Ndiye ndabhala kwaye ndiphonononga izixhobo ukususela kwi-2007, kwaye amanqaku ashicilelwe kwi-Fine Homebuilding, Le Ndlu endala, iSayensi ePhambili, i-Popular Mechanics kunye neZixhobo zoRhwebo.Ndaphinda ndasebenza njengomchweli, umlindi kunye nomphathi wendawo iminyaka eyi-10, ndisebenza kwiiprojekthi zokuhlala ezixabisa izigidi zeedola.Ngo-2011, ndaphinda ndadiliza indlu yam yasefama eneminyaka eli-100 ubudala, eyayifuna inkqubo yombane entsha kraca.
Ngolwazi oluthe kratya malunga nabavavanyi bombane abangaqhagamshelwanga nabo, ndithethe nabantu abazisebenzisa mihla le: uMark Tierney waseTierney Electrical, eHopkinton, Massachusetts.U-Tierney uneminyaka engama-20 yamava kwaye ebeqhuba inkampani yakhe ukusukela ngo-2010.
Umhloli we-voltage ongaqhagamshelani naye ufuna kuphela ukuba asondele ukuze abone i-current in the wire or socket.1 Bubukhulu kunye nokumila kwenqatha elibukhali.Ubhaqo lwenzeka kwincam yeprobe.Kwiimeko ezininzi, incam yeprobe yenzelwe ukutyhalelwa kwindawo yokuphuma.Kuba izinto ezothusayo zombane azimnandanga kakhulu kwaye ziyingozi kakhulu, esi sixhobo siluncedo nakweyona misebenzi ikhaphukhaphu yombane, njengokulungisa ingxaki kwi-thermostat okanye ukufakela i-dimmer switch.
Ngokucacileyo, sisixhobo esihle sombane we-DIY, kodwa nabantu abathambekele kumbane ongu-zero banokuzuza ngokuba nomnye.Ndihlala ndiyisebenzisa njengenqanaba lokuqala lokusombulula ingxaki ngaphambi kokufowunela ingcali yombane.
Umvavanyi ongaqhagamshelwani naye unokunceda kwimephu inkqubo yakho yombane ekhoyo.Andizange ndihlale kuyo nayiphi na indlu ekufutshane nephaneli ephawulweyo echanekileyo.Ukuba unendlu endala okanye indawo yokuhlala, ipaneli yakho yombane mhlawumbi ibhalwe ngendlela engeyiyo.Ukusombulula le ngxaki yinkqubo ethatha ixesha, kodwa kunokwenzeka.Cima zonke izaphuli zesekethe ngaphandle kwesinye, uze ujonge umsebenzi ojikeleze indlu.Nje ukuba uqikelele, bhala i-breaker circuit kwaye uqhubekele kwelinye elilandelayo.
Uninzi lwabavavanyi abangaqhagamshelwanga barekhoda kuphela umbane oqhelekileyo.Emva kokufunda ngalo mbandela, sigqibe kwelokuba i-voltage yoluhlu olumbini ifanelekile kwiibhokisi zezixhobo zasekhaya.Kumandla ombane asemgangathweni, isengasebenza ngokuqhelekileyo, kwaye kukho inzuzo eyongezelelweyo yokuchongwa kombane ophantsi, oluncedo kwiintsimbi zomnyango, ii-thermostats, ezinye izixhobo ze-AV, unkcenkceshelo kunye nezibane ezithile zomhlaba.Amaxabiso eemodeli ze-voltage ezimbini kunye ne-single-voltage ikakhulu phakathi kwe-US $ 15 kunye ne-US $ 25, ngoko ke izixhobo zoluhlu olumbini zenza ingqiqo njengesixhobo sokumisa esinye kwabo bangezongcali;ukuba nesakhono kunye nokungasisebenzisi kubaluleke ngaphezu kokusifuna nokungabi naso.kulungile.
Xa sithatha isigqibo sokuba yeyiphi imodeli ekufuneka siyivavanye, sifunde iAmazon, iHome Depot, kunye neemveliso zeLowes.Sikwajolise kubenzi bezixhobo zamandla abathembekileyo.Ukusukela ngoko, siye salunciphisa olu luhlu lwaba sixhenxe.
Senze ezinye iimvavanyo ukumisela ukusebenza kunye novakalelo lomvavanyi ngamnye.Okokuqala, ndacima isitshixo sombane esasikwibhokisi yombane ndaza ndazama ukufumanisa ukuba kweziphi iingcingo ezingama-35 ezaziphuma kuyo ezaphukileyo.Emva koko, ndathatha ucingo olufileyo ukuze ndibone ukuba ndingasisondeza na isixhobo kucingo oluphilayo kwaye ndiphinde ndifumane umvavanyi ukuba afunde i-negative.Ukongeza kolu vavanyo lolwakhiwo, ndikwasebenzise umvavanyi ukudibanisa iisokethi ezithile kwaye ndafakela izitshixo eziluzizi, ii-cooktops, iifeni zesilingi kunye nezinye ii-chandeliers.
I-Klein inokubona amandla ombane asemgangathweni kunye nombane ophantsi, kwaye ifakwe isibane esiluncedo-xa isibane sicinyiwe, unokufuna isixhobo esilungileyo.
Emva kokuphanda ngezihloko, ukuthetha nombane, kunye nokuchitha iiyure zokuvavanya iimodeli ezisixhenxe ezihamba phambili, sincoma i-Klein NCVT-3.I-NCVT-3 inokukhanya okubonakalayo okubonakalayo, iqhosha elihle lokuvula/lokucima kunye ne-onboard LED esebenza njengetotshi encinci.Le yinkalo enkulu, kuba xa uhlola i-voltage ye-wire, ukukhanya kunokungasebenzi kakuhle.Kwakhona iyahambelana nesokethi yobungqina be-tamper efunwa yikhowudi yangoku.I-NCVT-3 inesalathisi sobomi bebhetri kunye nomzimba ohlala ixesha elide okhusela izixhobo ze-elektroniki ezibuthathaka ukusuka kumathontsi ukuya kwi-6½ iinyawo.
Okona kubaluleke kakhulu, i-NCVT-3 ilula kakhulu ukuyisebenzisa.Sisixhobo soluhlu olumbini, ngoko siyakwazi ukubona amandla ombane asemgangathweni (iziseko, iingcingo eziqhelekileyo) kunye nombane ophantsi (intsimbi yomnyango, i-thermostat, iingcingo zokunkcenkceshela).Uninzi lwabavavanyi lubona kuphela amandla ombane asemgangathweni.Ngokungafaniyo nezinye iimodeli zoluhlu olukabini, inokutshintsha ngokuzenzekelayo phakathi koluhlu ngaphandle kokusebenzisa ukucofa okubuhlungu.Igrafu yebar ye-LED ecaleni kwesixhobo ibonisa amandla ombane ojongene nawo.Ukubona i-voltage ephantsi ikhanyisa izibane ezibini ze-orenji ezantsi, kwaye umbane oqhelekileyo ukhanyisa enye okanye ngaphezulu kwezibane ezibomvu ezithathu phezulu.Iinkampani ezininzi zithengisa ii-detectors eziphezulu kunye neziphantsi zoxinzelelo, kodwa kubantu abangengabo abachwephesha, kunengqiqo ukuzibeka kwisixhobo esinye, ngakumbi ukuba kulula ukusebenza njengoKlein.
Kwigumbi lam elingaphantsi, iingcingo zibethelelwe kwisilingi ngaphezulu kwezibane ze-fluorescent, ngoko ke nokuba izibane zikhanyile, kunzima ukuphatha iingcingo.Kwiimodeli ezimbini ezineethotshi, i-NCVT-3 yodwa enokuthi iqhutywe ngokuzimeleyo komsebenzi wokuvavanya, okulungileyo ngokwenene.
Isibane se-LED yeyona nto ibalaseleyo ye-NCVT-3.Kwigumbi lam elingaphantsi, iingcingo zibethelelwe kwisilingi ngaphezulu kwezibane ze-fluorescent, ngoko ke nokuba izibane zikhanyile, kunzima ukuphatha iingcingo.Kwiimodeli ezimbini ezineethotshi, i-NCVT-3 yodwa enokuthi iqhutywe ngokuzimeleyo komsebenzi wokuvavanya, okulungileyo ngokwenene.Xa umhloli evuliwe, kuya kubakho uluhlu lwee-beep kunye nezibane ezikhanyayo.Ukuba ufuna nje ukusebenzisa isibane, kuhle ukuba ukwazi ukuyiphepha.Ukhetho lwethu lokubaleka, i-Milwaukee 2203-20 i-voltage detector ene-LED nayo inomsebenzi wesibane, kodwa iya kukhanya kuphela xa i-tester ivuliwe, ngoko ke, kufuneka umamele i-beep, akukho ndlela. ukuba ukwigumbi elikhanyiswe kakuhle Cima isibane xa usebenza esixekweni.I-NCVT-3 LED ikwaqaqambile kune Milwaukee.
I-NCVT-3 nayo inemvakalelo ehlala ixesha elide.Ngokomenzi, unokumelana nokuhla kwe-6.5-foot, ngoko ke ukuba ufumana ukuwa, lo mzekelo uya kukunika ithuba lokusinda.Ukongezelela, izitshixo zivaliwe, kwaye isiciko sendawo yebhetri sitywinwe, ngoko i-NCVT-3 inokumelana nemvula encinci kunye nomswakama.UKlein unevidiyo malunga nesixhobo, kwaye kubonakala ngathi siphantsi kwempompo ethontsizayo.
Xa sabuza usombane uMark Tierney ukuba angacebisa nawuphi na umenzi kumninimzi, wasixelela ukuba "oyena uthembekileyo nguKlein."Ukwathanda iimodeli ezinee-LED.Uthe kubaninimzi, "baza kufumana izinto ezimbini ezintle kwisixhobo esinye."
Ngokuphathelele ubomi bebhetri, uKlein uthe iibhetri ezimbini ze-AAA ziya kubonelela ngeeyure ze-15 zokusebenzisa umhloli oqhubekayo kunye neeyure ze-6 zokusebenzisa isibane esiqhubekayo.Oku kwanele kubasebenzisi ngamanye amaxesha, njengoko besitshilo, kulungile ukuba nesalathisi sebhetri ukuze wazi xa isihla.
Asithi sodwa abathanda i-NCVT-3.UClint DeBoer, obhale kwiProToolReviews, wathi isixhobo "Nokuba wenza umsebenzi wombane ngamaxesha athile, ungaphantse usifumane lula."Waqukumbela ngelithi: “Esi sisixhobo esiyilwe kakuhle esinokwenza oko sifanele sikwenze.Kakuhle kakhulu.Khetha ibe nye.Awuyi kuzisola.”
I-NCVT-3 ikwafumene uphononongo oluhle ngokubanzi kwi-Amazon kunye ne-Home Depot.Uninzi lweendaba ezimbi kwiAmazon zivela kubantu abathanda isixhobo kodwa badanile kukuba asinakuqhagamshelwa kwisokethi.Njengoko kukhankanyiwe ngasentla, oku akuyongxaki kuba iyakwazi ukubona okwangoku kwaye ibonise kuphela njenge-voltage ephantsi (kwaye iyenze ihambelane ne-socket-proof socket efunwa yikhowudi).Ukuqinisekisa ngokwenene i-voltage esemgangathweni kwi-socket, kulula ukukrazula isigqubuthelo kwaye ubeke incam yesixhobo kwicala lesokhethi apho iingcingo zikhoyo.
I-NCVT-3 yodwa kuba ayinakuqhagamshelwa kwisokethi.Ukuqala nje kokubona, oku kubonakala kuyingxaki, njengoko uninzi lwabanye abavavanyi abangaqhagamshelwanga banokufunda amandla kwisokethi nje ngokuyifaka kwindawo yokuvula.Inyaniso kukuba ngenxa yokuba iyakwazi ukufunda i-voltages ephantsi, i-NCVT-3 isenako ukutsala okwangoku ngaphandle kwesokethi, eyona nto ibalulekileyo xa ujongana neesokethi zobungqina be-tamper-proof ngoku ezifunekayo ngeekhowudi zombane.Ukufakela iplagi kwelinye leesokethi, uxinzelelo olulinganayo kufuneka lusetyenziswe kwiindawo ezimbini zokuvula izikhonkwane (lo ngumba wokhuseleko lwabantwana).Ngezi sokethi, i-voltage yesiqhelo engadibanisiyo ayisoloko isebenza kuba inokufunda kuphela iivoltages eziqhelekileyo.Njengoko uBruce Kuhn, umlawuli wemveliso yophuhliso lwemveliso, uvavanyo kunye nomlinganiselo eKlein, wasixelela, "Ukuba wenza umvavanyi olulolo hlobo ukuba luvane ngokwaneleyo ukuze lubone amandla ombane angaphandle 'kwisokethi yobungqina be-tamper-proof, ke ikwindawo exineneyo. ibhokisi yombane.Ucingo olushushu.”2 Ngenxa yokuba i-NCVT-3 yenzelwe ukufumanisa i-voltage eqhelekileyo kunye ne-voltage ephantsi, xa ibekwe kwindawo yokuvula i-socket ephilayo, iya kuthatha i-voltage eqhelekileyo, kodwa isuka kude, ibonakala i-Voltage ephantsi. isaqinisekisa ukuba isokhethi iyaphila.
Kukho amaqhosha okulawula kwicala le-NCVT-3, apho uTierney wasixelela ukuba sinikele ingqalelo.Ulumkise ngelithi iimodeli ezinamaqhosha asecaleni kulula ukuzivula xa zifakwe epokothweni, nto leyo ayicaphukisi nje kuphela, kodwa inyusa isantya sokusetyenziswa kwebhetri.Omnye umahluko kwi-NCVT-3 kukuba amaqhosha agungxulwa nomphezulu;amaqhosha amaninzi afana neli aphuma kwicala lesixhobo kwaye angenziwa lula ngempazamo.Ndasebenzisa i-NCVT-3 epokothweni yam usuku, kwaye ayizange ivuleke.
Lo mvavanyi wamandla ombane amabini uyafana nokhetho lwethu kwezona zinto zibalulekileyo, kodwa ezinye zeenkcukacha zayo ezincinci ziyacaphukisa.
Ukuba i-Klein ayifumaneki, sincoma i-Milwaukee 2203-20 i-voltage detector ene-LED.Inemisebenzi emininzi efana neKlein NCVT-3, kodwa isibane asikhanyisi kangako kwaye asinakusetyenziswa ngokuzimeleyo kumvavanyi.Ikwakhupha i-beep ekhwaza ngendlela engakholelekiyo (akukho khetho luthuli).Oku kunokuba luncedo kwindawo yokusebenza enengxolo, kodwa emva kokuba ndichithe imizuzu engama-45 ndijonge iingcingo ezikwigumbi elingaphantsi, umthamo wawanele ukundenza ndiphambane kancinci.
Nangona kunjalo, iMilwaukee iyakwazi ukubona amandla ombane aphantsi kunye nomgangatho oqhelekileyo wombane, kwaye akukho switsha ngesandla phakathi kwabo, ngoko kulula ukuyisebenzisa njenge-NCVT-3.
Ngo-2019, siqaphele ukuba uKlein ngoku ungumnikazi we-NCVT-4IR.Ijongeka ngokufanayo nokukhetha kwethu, kodwa ikwabandakanya nomsebenzi wethermometer ye-infrared.Sikholelwa ukuba oku akufanelanga ukunyuswa kweendleko zokusetyenziswa rhoqo ekhaya.
Siye saqaphela kwakhona imifuziselo kwiinkampani ezifana Meterk, ToHayie, Taiss, kunye SOCLL.Ezi zixhobo eziqhelekileyo ezivela kwiinkampani ezingaziwayo.Sivakalelwa kukuba kukhuselekile ukucebisa abavavanyi kubenzi bezixhobo zokuxilonga zombane eziqinisekisiweyo.
Sivavanye i-Klein NCVT-2, efana kakhulu ne-NCVT-3.Ikwayimodeli yoluhlu olumbini olunokuthi lubone ngokuzenzekelayo phakathi koluhlu olubini, kodwa alunayo i-LED;iqhosha lokuvula / lokuvala liyaziqhenya ngayo (ngoko kunokwenzeka ukuba livulwe epokothweni);kwaye imeko ayinayo loo mvakalelo yokuqina.
Siye sabona iGreenlee GT-16 kunye neSperry VD6505 zisebenzisa i-dial ukukhetha ubuntununtunu phakathi kombane ophantsi kunye nombane oqhelekileyo.Ngethuba lokuvavanya kwethu, sifumene ukuba xa kukho iingcingo ezininzi kwindawo, le mizekelo iya kufumana izibonakaliso kwezinye iingcingo, okwenza kube nzima ukuba sazi xa uvakalelo luncitshisiwe ngokwaneleyo ukufumana kuphela iingcingo esizifunayo.Kunzima ukuqonda amaqhinga okudayela ngovakalelo, kwaye ukhetha ujongano olulula lweMilwaukee kunye neKleins.
I-Greenlee TR-12A inoyilo lwe-pin-ezimbini ngokukodwa kwi-sockets-proof sockets, kodwa inokufunda kuphela ii-voltages eziqhelekileyo endaweni yombane ophantsi, ngoko sicinga ukuba i-NCVT-3 iluncedo ngakumbi.
I-Klein NCVT-1 ibona kuphela amandla ombane asemgangathweni.Ndinenye iminyaka emininzi kwaye bendisoloko ndiyifumanisa ichanekile kwaye inokuthenjwa, kodwa iyavakala ukufumana imodeli enokuthi ibone umbane ophantsi.
Sacela u-Klein ukuba achaze ngokuchanekileyo umgaqo wokusebenza we-non-contact voltage tester.Inkampani isixelela ukuba: “Isixhobo esivavanya amandla ombane esingaqhagamshelwanga sisebenza ngokuphembelela indawo ye-electromagnetic eyenzelwe ukujikeleza i-conductor eqhutywa ngumthombo wangoku otshintshanayo (AC).Ngokubanzi, Okukhona uphezulu umbane osetyenziswayo kwi-conductor, kokukhona ukomelela kwentsimi yentsimi ye-electromagnetic ehambelanayo.Inzwa kwisixhobo sovavanyo esingaqhagamshelwanga siphendula ngokwamandla entsimi ye-electromagnetic field.Ngokusekwe kulo mgaqo-siseko, xa umvavanyi wombane ongaqhagamshelwanga ukufutshane nomqhubi onamandla Xa ubekiwe, amandla ombane owenziweyo abangela ukuba isixhobo “sazi” nokuba sikwindawo enevoltage ephantsi okanye ikwindawo enevoltheji ephezulu.
Ndithathe iKlein NCVT-1 ijikeleze ikhaya lam.Ibona kuphela iivolthi eziqhelekileyo.Izinga lokuphumelela lokubona amandla kwiisokethi ezinobungqina be-tamper malunga ne-75%.
UDoug Mahoney ngumbhali ophezulu wabasebenzi eWirecutter, oquka ukuphuculwa kwekhaya.Usebenze kwintsimi yolwakhiwo oluphezulu iminyaka eyi-10 njengomchweli, umlindi kunye nomphathi.Uhlala kwindlu yasefama eneminyaka engama-250 ubudala, yaye uchithe iminyaka emine ecoca yaye esakha ikhaya lakhe langaphambili.Ukwafuya iigusha, afuye inkomo, aze asenge rhoqo kusasa.
Kulo nyaka siye savavanya iimpuku zokudlala ezingama-33 ukuze sifumane ezona zi-5 zifanelekileyo kumdlalo wentambo okanye ongenazingcingo, kubandakanya neenketho ezinexabiso eliphantsi.
Emva kweeyure ezingaphezu kwama-350 zophando kunye novavanyo lwezixhobo ezingaphezulu kwama-250, siye sahlanganisa eyona khithi ilungileyo yekhaya lakho.
Isiselo esikhulu esingesiso isiselo esinxilisayo sinencasa entsonkothileyo njengecocktail enxilisayo, kwaye siyabhiyoza ngokulinganayo.Siye sasela iziselo ezinganxiliyo ezingama-24 ukuze sifumane ezona zilungileyo.

Uvavanyo lokumelana ne-voltage lwenziwa ngomthombo wombane ophezulu kunye nombane kunye neemitha zangoku.Isixhobo esinye esibizwa ngokuba yi-“pressure test set” okanye “hipot tester” sisoloko sisetyenziswa ukwenza olu vavanyo.Isebenzisa amandla ombane ayimfuneko kwisixhobo kwaye ijonge ukuvuza kwangoku.Ikhoyo ngoku inokukhubaza isalathisi sempazamo.Umvavanyi unokhuseleko lomthwalo ogqithisiweyo.Amandla ombane ovavanyo anokuba ngawo angoku ngokuthe ngqo okanye aguqukayo angoku kumbane ohamba rhoqo okanye amanye amaza, njenge-resonant frequency (30 ukuya kwi-300 Hz egqitywe ngumthwalo) okanye i-VLF (0.01 Hz ukuya kwi-0.1 Hz), xa kufanelekile.Amandla ombane aphezulu anikwe kumgangatho wovavanyo wemveliso ethile.Ireyithi yesicelo inokuhlengahlengiswa ukulawula imisinga yokuvuza okubangelwa kwiziphumo zendalo ze-capacitive zento yovavanyo.Ubude bexesha lovavanyo luxhomekeke kwiimfuno zovavanyo zomnini we-asethi kodwa ngokuqhelekileyo ukuya kuthi ga kwimizuzu emi-5.Amandla ombane asetyenzisiweyo, isantya sokusetyenziswa kunye nobude bexesha lovavanyo luxhomekeke kwiimfuno ezichaziweyo zesixhobo.Imigangatho yovavanyo eyahlukeneyo iyasebenza kubathengi bombane, izixhobo zombane zomkhosi, iintambo zombane ophezulu, izixhobo zokutshintsha kunye nezinye izixhobo.[2]

Isixhobo se-hipot esivuzayo sokuvuza kwangoku izicwangciso zomda wohambo ziphakathi kwe-0.1 kunye ne-20 mA[3] kwaye zisetwa ngumsebenzisi ngokweempawu zento yovavanyo kunye nesantya sosetyenziso lombane.Injongo kukukhetha useto lwangoku olungayi kubangela ukuba umvavanyi ahambe ngobuxoki ngexesha lokusetyenziswa kwamandla ombane, ngelixa kwangaxeshanye, ukhetha ixabiso elinciphisa umonakalo onokwenzeka kwisixhobo esiphantsi kovavanyo ukuba ukukhutshwa ngokungazi okanye ukuphuka kwenzeka.
