Umehluko phakathi kwedivayisi yokuhlola i-voltage ye-DC kanye nedivayisi yokuhlola i-voltage ye-AC

1. Uhlukile ngemvelo

Idivayisi ye-AC imelana nokuhlola i-voltage: indlela ephumelela kakhulu neqondile yokuhlonza amandla okufakwa kwezinto kagesi.

I-DC imelana nedivayisi yokuhlola i-voltage: ukuthola i-voltage enkulu uma kuqhathaniswa nephezulu into ekwazi ukumelana nayo ngaphansi kokuhlolwa kwamandla kagesi aphezulu.

2. Ukucekela phansi okuhlukile

I-DC imelana nedivayisi yokuhlola i-voltage: Njengoba ukufakwa ngaphansi kukagesi we-DC ngokuyisisekelo kungakhiqizi ukulahlekelwa kwe-dielectric, i-DC ukumelana ne-voltage inomonakalo omncane ku-insulation.Ngaphezu kwalokho, njengoba i-DC imelana ne-voltage idinga kuphela ukuhlinzeka ngokuvuza okuncane, imishini yokuhlola edingekayo inomthamo omncane futhi kulula ukuyiphatha.

I-GDYD-M yochungechunge lwe-insulation imelana nedivayisi yokuhlola i-voltage

I-AC ukumelana ne-voltage: I-AC ukumelana ne-voltage ilimaza kakhulu ukufakwa kwe-insulation kune-DC ukumelana ne-voltage.Njengoba umshini wokuhlola uyi-capacitive current, imishini yokuhlola umthamo omkhulu iyadingeka.

Ukuhlolwa kokuvimbela i-insulation

Ukuhlolwa kokuvimbela ukufakwa kwemishini kagesi kuyisinyathelo esibalulekile sokuqinisekisa ukusebenza okuphephile kwemishini.Ngokuhlolwa, isimo sokufakelwa kwezinto zokusebenza singaqondwa kahle, amaphutha afihliwe ngaphakathi kokufakwa kungatholakala ngesikhathi, futhi amaphutha angaqedwa ngokulungiswa.Uma ibucayi, kufanele ishintshwe ukuze kuvinjwe ukuthi ukufakwa kwamathuluzi kungenzeki ngesikhathi sokusebenza.ukuphuka, okuholela ekulahlekelweni okungenakulungiseka njengokucisha kukagesi noma ukulimala kwemishini.

Ukuhlolwa kokuvimbela ukufakwa kwe-insulation kungahlukaniswa izigaba ezimbili:

Olunye ukuhlolwa okungabhubhisi noma ukuhlolwa kwesici sokufakelwa, okuyizinhlobonhlobo zamapharamitha wesici akalwa ku-voltage ephansi noma ngezinye izindlela ezingeke zilimaze okokufaka, ikakhulukazi okubandakanya ukukalwa kokumelana nokufakwa kwe-insulation, ukuvuza kwamanje, i-tangent yokulahleka kwe-dielectric njll. ., ukuze kwahlulele ukuthi kukhona yini ukonakala ngaphakathi kokwahlukanisa.Ukuhlola kufakazele ukuthi lolu hlobo lwendlela luyasebenza, kodwa alukwazi ukusetshenziselwa ukwahlulela ngokuthembekile amandla e-dielectric of insulation okwamanje.

Okunye ukuhlola okulimazayo noma idivayisi yokuhlola amandla kagesi.I-voltage esetshenziswa ekuhlolweni iphakeme kune-voltage yokusebenza yemishini.I-standard voltage ikakhulukazi ifaka i-DC ukumelana ne-voltage, i-AC ukumelana ne-voltage nokunye.Ububi bokusebenzisa idivayisi yokuhlola i-voltage ukuthi izodala umonakalo othile ku-insulation.
