Ama-circuit breaker kufanele aqonde umqondo ojwayelekile

I-vacuum circuit breaker ikakhulukazi ihlanganisa izingxenye ezintathu: igumbi lokucisha i-arc yepompo ye-vacuum, induction ye-electromagnetic noma inhlangano yokusebenza yangempela ye-torsion spring, kanye nohlaka lokusekela.
Impilo ye-vacuum circuit breaker ihlanganisa impilo yepompo ye-vacuum, impilo yemishini yokusebenza kanye nempilo yezinto zokusebenza zikagesi.
Vacuum circuit breaker.
1. Isikhathi somjikelezo wokulungisa.
Igumbi lokucisha i-arc le-vacuum circuit breaker ngokwayo ayidingi ukulungiswa. I-vacuum circuit breaker idinga kuphela ukufakwa futhi ilungiswe njengoba kudingekile, futhi inhloko-dolobha ingasetshenziswa, futhi ukugcinwa ngesikhathi sokusebenza kulula. Ngesikhathi sokusebenza kwe-vacuum circuit breaker, lapho imvamisa yokusebenza ifinyelela ingxenye eyodwa kwesihlanu yempilo yemishini engumshini, amandla kufanele anqanyulwe ukuze kwenziwe ukuhlola okuphelele nokulungiswa. Okufana nempilo yemishini engumshini. Uma izinto zikagesi zisekupheleni kwempilo yazo, nciphisa izikhathi zomjikelezo wokuhlola nokulungiswa ngangokunokwenzeka.
2. Hlola okuqukethwe okuthile kokulungisa.
Ukuhlola nokulungiswa ikakhulukazi kufaka izici ezilandelayo:
(1). Qinisa izingxenye zokuxhuma zamatheminali esekethe yokulawula eyinhloko.
(2) Hlanza inhlangano yangempela yokusebenza kanye ne-casing yegumbi lokucisha i-arc.
(3) Engeza amafutha endaweni yokuzivocavoca umzimba, bese ubuyisela indawo eyonakele negugulekile.
(4) Hlola indawo yokuxhumana ngomonakalo.
(5) Hlola idigri yevacuum yegumbi lokucisha i-arc lephampu yevacuum.
(6) Lungisa amanye amapharamitha ayinhloko (ikakhulukazi ibanga lokuvula i-circuit breaker. Hlola futhi ulungise uhlelo lokuhamba oluncishisiwe).
3. Cacisa bese ubuyisela idigri ye-vacuum ye-arc chute.
(1) Ukuhlolwa kwezinga le-vacuum yegumbi lokucisha i-arc.
Idigri ye-vacuum ye-vacuum circuit breaker ihlobene ngokushesha nokusebenza kwe-flame retardant kanye nezici zokucisha i-arc zeswishi ehlukanisayo. Ekuphileni kwansuku zonke, kunzima ukuhlukanisa kahle izinga le-vacuum yegumbi lokucima i-arc. Indlela evamile ukusebenzisa indlela yokuminyanisa ye-DC ukuze unqume ukuthi idigri ye-vacuum isezingeni elifanele.
(2) Khipha futhi ubeke esikhundleni segumbi lokucisha i-arc.
Umsebenzi wokudiliza nokufaka esikhundleni se-arc chute ulula, futhi ngokuvamile ungenziwa ngokuvumelana nezidingo zemanuwali yomkhiqizi. Ngemuva kokuhlakazeka nokushintshwa, imininingwane yokufakwa kwemishini yomshini. Ukuhlelwa kwe-stroke yesixhumi. Ukuhamba ngaphezulu. Kala ngokunembile amabanga. Nokho, kuzomele kwenziwe izinguquko lapho kuvalwa. Bese uthatha amandla okukhipha i-AC ukumelana nokuhlolwa kwe-voltage.
