Ububi bokuhlolwa kwe-Direct Current (DC).
(1) Ngaphandle uma kungekho amandla entweni elinganisiwe, amandla kagesi okuhlola kufanele aqale “kuziro” futhi akhuphuke kancane ukuze agweme ukushaja kwamanje okukhulu.I-voltage eyengeziwe nayo iphansi.Uma i-chargency yokushaja inkulu kakhulu, izodala ukungahluleli kahle komhloli futhi yenze umphumela wokuhlola ungalungile.
(2) Njengoba i-DC imelana nokuhlolwa kwe-voltage izokhokhisa into evivinywayo, ngemva kokuhlolwa, into evivinywayo kufanele ikhishwe ngaphambi kokudlulela esinyathelweni esilandelayo.
(3) Ngokungafani nokuhlolwa kwe-AC, i-DC ukumelana nokuhlolwa kwe-voltage ingahlolwa kuphela nge-polarity eyodwa.Uma umkhiqizo uzosetshenziswa ngaphansi kwe-voltage ye-AC, lokhu kungalungile kufanele kubhekwe.Lesi futhi isizathu esenza ukuthi iningi labalawuli bezokuphepha bancome ukusebenzisa i-AC ukumelana nokuhlolwa kwamandla kagesi.
(4) Ngesikhathi sokuhlolwa kwe-AC ukumelana ne-voltage, inani eliphakeme kakhulu likagesi liphindwe izikhathi ezingu-1.4 inani eliboniswa imitha kagesi, elingakwazi ukuboniswa imitha kagesi evamile, futhi elingenakutholwa yi-DC ukumelana nokuhlolwa kwamandla kagesi.Ngakho-ke, imithethonqubo eminingi yokuphepha idinga ukuthi uma kusetshenziswa i-DC ukumelana nokuhlolwa kwe-voltage, i-voltage yokuhlola kufanele inyuswe ibe yinani elilinganayo.
Ngemuva kokuthi i-DC ukumelana nokuhlolwa kwe-voltage kuqediwe, uma into evivinywayo ingakhishwa, kulula ukubangela ukushaqeka kukagesi ku-opharetha;zonke izihloli zethu ze-DC ezimelana ne-voltage zinomsebenzi wokukhipha ngokushesha ongu-0.2s.Ngemuva kokuthi ukuhlolwa kwe-DC ukumelana ne-voltage kuqediwe, umhloli Ingakwazi ukukhipha ugesi ngokuzenzakalelayo emzimbeni ohloliwe ngaphakathi kwama-0.2s ukuvikela ukuphepha komsebenzisi.
Isingeniso sezinzuzo kanye nokubi kwe-AC ukumelana nokuhlolwa kwamandla kagesi
Ngesikhathi sokuhlolwa kwe-voltage ukumelana, i-voltage esetshenziswa i-voltage tester emzimbeni ohloliwe inqunywa kanje: phindaphinda i-voltage yokusebenza yomzimba ohloliwe ngo-2 bese wengeza i-1000V.Isibonelo, i-voltage yokusebenza yento ehloliwe ingu-220V, lapho ukuhlolwa kwe-voltage ye-standard kwenziwa, i-voltage ye-standard voltage tester ingu-220V+1000V=1440V, ngokuvamile ngu-1500V.
Ukuhlolwa kwe-voltage ye-standard kuhlukaniswe ukuhlolwa kwe-AC ukumelana ne-voltage kanye ne-DC ukumelana nokuhlolwa kwe-voltage;okuhle nokubi kokuhlolwa kwe-AC ukumelana ne-voltage imi kanje:
Izinzuzo ze-AC ukumelana nokuhlolwa kwe-voltage:
(1) Ngokuvamile, ukuhlola kwe-AC kulula ukwamukela iyunithi yokuphepha kunokuhlola kwe-DC.Isizathu esiyinhloko ukuthi imikhiqizo eminingi isebenzisa i-alternating current, futhi ukuhlola kwamanje okushintshayo kungahlola i-polarity enhle nengalungile yomkhiqizo ngesikhathi esifanayo, ehambisana ngokuphelele nendawo lapho umkhiqizo usetshenziswa futhi uhambisana khona. nesimo sokusetshenziswa sangempela.
(2) Njengoba ama-capacitor alahlekile engakwazi ukushajwa ngokugcwele ngesikhathi sokuhlolwa kwe-AC, kodwa ngeke kube khona inrush yamanje, ngakho-ke asikho isidingo sokuvumela i-voltage yokuhlola ikhuphuke kancane, futhi i-voltage egcwele ingengezwa ekuqaleni ukuhlolwa, ngaphandle uma umkhiqizo uzwela ku-voltage ye-inrush ebucayi kakhulu.
(3) Njengoba ukuhlolwa kwe-AC kungakwazi ukugcwalisa lawo mandla alahlekile, asikho isidingo sokukhulula into yokuhlola ngemva kokuhlolwa, okungenye inzuzo.
Ububi be-AC ukumelana nokuhlolwa kwe-voltage:
(1) Okungalungile okuyinhloko ukuthi uma amandla alahlekile ento elinganisiwe makhulu noma into elinganisiwe ingumthwalo we-capacitive, i-current ekhiqizwayo izoba nkulu kakhulu kunomsinga wangempela wokuvuza, ngakho-ke ukuvuza kwangempela kwamanje akunakukwaziwa.okwamanje.
(2) Okunye okungalungile ukuthi njengoba okwamanje okudingwa amandla alahlekile ento ehloliwe kufanele kuhlinzekwe, okukhiphayo kwamanje ngomshini kuzoba kukhulu kakhulu kunamanje uma usebenzisa ukuhlolwa kwe-DC.Lokhu kwandisa ubungozi ku-opharetha.
Ingabe ukhona umehluko phakathi kokutholwa kwe-arc kanye nokuhlola okwamanje?
1. Mayelana nokusetshenziswa komsebenzi wokuthola i-arc (ARC).
a.I-Arc iyinto engokoqobo, ikakhulukazi i-voltage ye-pulsed high-frequency.
b.Izimo zokukhiqiza: umthelela wendawo, umthelela wenqubo, umthelela wezinto ezibonakalayo.
c.I-Arc ikhathazeka kakhulu yiwo wonke umuntu, futhi ingenye yemibandela ebalulekile yokukala ikhwalithi yomkhiqizo.
d.Uchungechunge lwe-RK99 olulawulwa yi-standard tester olukhiqizwa inkampani yethu lunomsebenzi wokutholwa kwe-arc.Isampula isignali ye-high-frequency pulse ngenhla kuka-10KHz ngesihlungi se-high-pass enempendulo yefrikhwensi engaphezu kuka-10KHz, bese iyiqhathanisa nebhentshimakhi yethuluzi ukuze inqume ukuthi ifanelekile yini.Ifomu lamanje lingasethwa, futhi ifomu leleveli lingasethwa.
e.Indlela yokukhetha izinga lokuzwela kufanele isethwe umsebenzisi ngokuya nezici zomkhiqizo kanye nezidingo.
