1, Isimiso sokuhlola:
a) ubekezelela ukuhlolwa kwe-voltage:
Umgomo oyisisekelo wokusebenza ngukuthi: Qhathanisa namanje evuvuthwa ekhiqizwe ithuluzi elihlolwe kumandla kagesi aphezulu wokukhishwa kokuhlolwa nguMhloli weVoltage Traject nge-Preset Tester yamanje. Uma i-evuza yamanje etholakele ingaphansi kwenani esethiwe, ithuluzi lidlula isivivinyo. Lapho kutholwa khona manje ukuvuza kutholakale kukhulu kunesahlulelo samanje, i-applov voltage inqunywa bese kuthunyelwa i-alamu ebonakalayo futhi ebonakalayo, ukuze kunqunywe amandla okumelana nengxenye yengxenye ehlolwe.
Ngomgomo wokuqala wokuhlola umhlabathi wokuhlola,
I-voltage i-handpant i-acter ihlanganiswa ikakhulukazi i-AC (Direct) yamandla aphezulu kagesi aphezulu, isilawuli sesikhathi, umjikelezo wokuthola, inkomba yesekeluzi kanye ne-alamu yeseker. Isimiso esiyisisekelo sokusebenza yilesi: Isilinganiso sokuvuza kwamanje esikhiqizwe ithuluzi elihlolwe ekutholeni okuphezulu kwe-voltage act by the Voltage Teoter kuqhathaniswa nesahlulelo esethiwe. Uma i-evuza yamanje etholakele ingaphansi kwenani esethiwe, idivaysi idlulisela isivivinyo, lapho kutholwa amanje, lapho i-arktage ebonakalayo inqunywa okwesikhashana futhi i-alamu ebonakalayo ithunyelwa ukuze ithole amavolushi umemela amandla engxenye ehlolwe.
b) Ukuvimbela Ukuvimbela:
Siyazi ukuthi i-voltage yokuhlolwa kokufakelwa kokufakelwa ngokuvamile i-500V noma i-1000V, elingana nokuhlola i-DC imelana nokuhlolwa kwe-voltage voltage. Ngaphansi kwalolu volfage, ithuluzi lilinganisa inani lamanje, bese likhulisa ukubalwa kwamanje kwesifunda sangaphakathi. Ekugcineni, kudlula umthetho we-ohm: r = u / i, lapho uhlolwe i-500V noma i-1000v, futhi yiwo okuvuza kwamanje kwalolu voltage. Ngokusho kwesipiliyoni sokuhlola se-handstand voltage, siyakwazi ukuqonda ukuthi okwamanje kuncane kakhulu, ngokuvamile kungaphansi kwe-1 μ a.
Kungabonakala kulokhu okungenhla ukuthi umgomo wokuhlolwa kokufakelwa kokufakelwa okufanayo nalokho okumelene novivinyo lwe-voltage, kepha kungenye nje inkulumo yoMthetho weHhom. Ukuvuza kwamanje kusetshenziselwa ukuchaza ukusebenza kwento yokufaka kwento evivinywa, ngenkathi ukulimazeka kokufakelwa ukumelana.
2, Inhloso Yokwenza Amandla Wokumelana Nokuhlola:
I-Voltage Worntate Test isivivinyo esingeyona eyonakalisayo, esetshenziselwa ukuthola ukuthi umthamo wokufaka imikhiqizo ufaneleke ngaphansi komoya ophakeme we-trans. Kusebenza i-high voltage kwimishini ehloliwe isikhathi esithile ukuqinisekisa ukuthi ukusebenza kokufakwa kwemishini kuqinile ngokwanele. Esinye isizathu salolu vivinyo ukuthi lungaphinde lubone iziphambeko ezithile zensimbi, njengebanga elinganele elinganele futhi imvume enganele kagesi enqubweni yokukhiqiza.
I-3, i-voltage voltate i-test voltage:
Kunomthetho ojwayelekile we-Test Voltage = Amandla ahlinzekelwe amandla okuphakelayo × 2 1 1000V.
Isibonelo: Uma amandla ahlinzeka nge-voltage yomkhiqizo wokuhlola angama-220v, i-test voltage = 220V × 2 + 1000v = 1480v.
Ngokuvamile, isikhathi sokuhlola se-voltage voltage umzuzu owodwa. Ngenxa yenani elikhulu izivivinyo zokumelana nogesi emugqeni wokukhiqiza, isikhathi sokuhlola kwesinye isikhathi sincishiswa sibe yimizuzwana embalwa. Kunomgomo ojwayelekile osebenzayo. Lapho isikhathi sokuhlola sehliswa kube yimizuzwana eyi-1-2 kuphela, i-test voltage kumele inyuswe ngo-10-20%, ukuze iqinisekise ukuthembeka kokufakwa kwesikhashana esifushane.
4, Alarm Okwamanje
Ukuhlelwa kwe-alamu okwamanje kuzonqunywa ngokuya ngemikhiqizo ehlukene. Indlela engcono kakhulu yokwenza ukuhlolwa okuvuza kwamanje kwe-batch yamasampula kusengaphambili, thola inani eliphakathi, bese unquma inani eliphakeme kancane kunenani eliphakathi le-average njengamanje le-average yamanje. Ngoba i-evuza yamanje yensimbi ehlolwe ikhona ngokungenakuphikiswa, kuyadingeka ukuqinisekisa ukuthi isethi yamanje ye-alamu inkulu ngokwanele ukugwema ukwenziwa kwephutha lamanje, futhi kufanele kube lincane ngokwanele ukugwema ukudlulisa isampula elivuvukala. Kwezinye izimo, kuyenzeka futhi ukuthola ukuthi isampula lixhumana nokuphela kokukhishwa komhloli we-voltage ngokusetha okuthiwa i-alamu ephansi yamanje.
5, Ukukhetha ukuhlolwa kwe-AC ne-DC
Amandla okuhlola, iningi lamazinga okuphepha livumela ukusetshenziswa kwe-AC noma i-DC voltage ekubhekaneni nokuhlolwa kwe-voltage. Uma kusetshenziswa i-ac test voltage, lapho i-peak voltage ifinyelelwa, i-insulator izohlolwa izothwala ingcindezi enkulu lapho inani eliphakeme lihle noma libi. Ngakho-ke, uma kunqunywa ukuthi kukhethe ukusebenzisa isivivinyo se-DC Voltage, kuyadingeka ukuqinisekisa ukuthi i-DC Test Voltage iyinhlangano-voltage evuthayo kabili, ukuze i-DC voltage ilingane nenani eliphakeme le-AC voltage. Isibonelo: I-1500V AC voltage, ye-DC voltage ukukhiqiza inani elifanayo lokuxineka kukagesi kumele kube ngo-1500 × 1.414 ngu-2121v DC voltage.
Enye yezinzuzo zokusebenzisa i-DC Test Voltage yilokho kumodi ye-DC, ukugeleza kwamanje nge-alamu yokulinganisa yamanje ye-Voltage Tester's okugeleza kwamanje ngesampula. Enye inzuzo yokusebenzisa ukuhlolwa kwe-DC ukuthi i-voltage ingasetshenziswa kancane kancane. Lapho i-voltage inyuka, opharetha angathola ukugeleza kwamanje ngesampula ngaphambi kokuphuka kwenzeka. Kubalulekile ukuqaphela ukuthi uma usebenzisa i-DC Voltage Voltate HandStand, isampula kufanele ikhishwe ngemuva kokuthi isivivinyo sesiphothulwe ngenxa yokushaja kwe-capcait. Eqinisweni, noma ngabe kuhlolwe kangaki amandla kanye nezimpawu zomkhiqizo, kuhle ekukhipheni ngaphambi kokusebenzisa umkhiqizo.
Okubi kwe-DC Voltage Voltage Witter Ukuhlolwa ukuthi kungafaka kuphela amavolumu wokuhlola endaweni eyodwa, futhi akunakusebenzisa ukucindezelwa kukagesi ebukhosini obubili njengovivinyo lwe-AC, kanye nemikhiqizo eminingi ye-elekthronikhi. Ngaphezu kwalokho, ngoba i-DC Test Voltage kunzima ukuyikhiqiza, izindleko zokuhlolwa kwe-DC ziphakeme kunalezo zokuhlola i-AC.
Inzuzo ye-AC Volutage i-Worntate Test ukuthi ingabona wonke ama-voltage polarity, asondelene nesimo esisebenzayo. Ngaphezu kwalokho, ngoba i-ac voltage ngeke ikhokhise amandla, ezimweni eziningi, inani elizinzile lamanje lingatholakala ngokuqondile ngokuqondile i-voltage ehambisanayo ngaphandle kokugqwala okuhambelana kancane. Ngaphezu kwalokho, ngemuva kokuqedwa ukuhlolwa kwe-AC, akukho lutho olusampumpu luyadingeka.
Ukushoda kwe-AC Votatege Voltate Test ukuthi uma kunekhono elikhulu le-y emugqeni ngaphansi kovivinyo, kwezinye izimo, ukuhlolwa kwe-AC kuzobe kudingwa kabi. Amazinga amaningi okuphepha avumela abasebenzisi ukuthi bangakwazi ukuxhuma ama-capacitors y ngaphambi kokuhlolwa, noma esikhundleni salokho basebenzise izivivinyo ze-DC. Lapho i-DC voltage eaptation ehambisa ukuhlolwa inyuke e-y capacitance, ngeke ihlushwe kabi ngoba amandla ngeke avumele noma yikuphi okukhona njengamanje.
