Iswishi Yokuphumula Yomthwalo Ophezulu Ecwiliswe Uwoyela

Isimiso sokusebenza seswishi yomthwalo we-voltage ephezulu sifana nese-circuit breaker. Ngokuvamile, kufakwa idivayisi elula yokucisha i-arc, kodwa isakhiwo sayo silula. Isithombe sibonisa iswishi yomthwalo we-high-voltage yomoya ocindezelwe. Inqubo yaso yokusebenza yile: lapho ibhuleki livulwa, ngaphansi kwesenzo sesipilingi esivulayo, i-main shaft ijikeleza ngokwewashi. Ngakolunye uhlangothi, i-piston iya phezulu nge-crank-slider mechanism ukuze icindezele igesi; Ngakolunye uhlangothi, ngesistimu yokudlulisa eyakhiwe ngamasethi amabili e-four-bar linkage mechanism, ummese oyinhloko uvulwa kuqala, bese ummese wokucisha i-arc ucindezelwa ukuvula i-arc contact, bese umoya ocindezelwe ku-cylinder ukhipha i-arc nge-nozzle. Lapho ivala, nge-main shaft kanye nesistimu yokudlulisa, i-main blade kanye ne-arc-extinguishing blade zijikeleza ngokwewashi ngesikhathi esifanayo, futhi i-arc contact ivaliwe kuqala; i-main shaft iyaqhubeka nokujikeleza, ukuze i-main contact ivalwe kamuva. Ngesikhathi senqubo yokuvala, i-opening spring igcina amandla ngesikhathi esifanayo. Njengoba inkinobho yokulayisha ingakwazi ukuphula ugesi we-short-circuit, ivame ukusetshenziswa kanye ne-fuse ene-high-voltage ekhawulela ugesi. Umsebenzi we-current-limiting we-fuse ene-current-limiting awukwazi nje ukuqeda umsebenzi wokuphula ugesi, kodwa futhi unciphise kakhulu ukushisa okubangelwa ugesi we-short-circuit kanye namandla kagesi.

Umphumela wokushintsha umthwalo we-high-voltage ocwiliswe uwoyela:
Iswishi yomthwalo ecwiliswe ku-oyela we-transformer ifakiwe ku-oyela we-transformer. Iswishi yomthwalo iyithuluzi lokushintsha phakathi kwe-circuit breaker kanye neswishi yokuhlukanisa. Inedivayisi elula yokucima i-arc, enganquma ugesi womthwalo olinganisiwe kanye nogesi othile wokulayisha ngokweqile, kodwa ayikwazi ukusika ugesi we-short-circuit. Iswishi yomthwalo ecwiliswe ku-oyela iyiswishi yokuxhumanisa yezigaba ezintathu efakwe ku-transformer ehlanganisiwe futhi isebenzisa uwoyela we-transformer njengendawo yokuvala nokuvala i-arc. Uwoyela we-transformer uwumkhiqizo wokuhlukanisa uphethiloli, futhi izingxenye zawo eziyinhloko yi-alkanes, ama-hydrocarbon agcwele i-naphthenic, ama-hydrocarbon angenasawoti anuka kamnandi kanye nezinye izinto ezihlanganisiwe. Ngokuvamile aziwa ngokuthi uwoyela we-square shed, uketshezi olukhanyayo oluphuzi olubonakalayo, ubuningi obuhlobene 0.895. Iphuzu lokuqandisa <-45 ℃. Sebenzisa amandla e-arc ngokwayo ukubola nokufaka igesi ku-oyela ozungeze i-arc bese uyipholisa ukuze ucime i-arc. Isakhiwo silula, kodwa isisindo sikhulu, futhi sifanelekile emikhiqizweni yangaphandle engu-35kV nangaphansi.
