Iswitshi se-voltage ephezulu sibhekisela emisebenzini yokuvala, ukulawula noma ukuvikela ekukhiqizeni ugesi, ukudlulisa, ukusatshalaliswa, ukuguqulwa kwamandla kanye nokusetshenziswa kohlelo lwamandla. Iswitshi se-voltage ephezulu sisetshenziselwa imikhiqizo kagesi enezinga le-voltage elingu-3.6kV ~ 550kV, i-voltage ephezulu...

Umsebenzi oyinhloko webhokisi legatsha lekhebula ukuhlukanisa noma ukushintshanisa izintambo. Ukuqhekeka kwekhebula. Ukuthwala izintambo eziningi ezincane zendawo yonke endleleni enebanga elide kuvame ukuholela ekuphazanyisweni nasekuchithekeni kokusetshenziswa kwekhebula, ngakho-ke ngaphandle kwemingcele yomthwalo wamandla, isigxobo esiyinhloko nezintambo ezinkulu ...

Isimiso sefusi yamandla Ifusi yamandla ingenye yamafusi, okubhekisela kumshini kagesi ohlanganisa ukuncibilika nokushisa okukhiqizwa ngokwawo bese unqamula isekethe lapho ugesi udlula inani elithile. Ifusi iyisivikelo samandla esenziwe ngokusebenzisa ukushisa okukhiqizwa yi...

Iswishi yokulayisha iyidivayisi yokushintsha phakathi kwe-circuit breaker kanye neswishi yokuhlukanisa. Inemishini elula yokucima i-arc, engavimba ugesi owengeziwe kanye nogesi othize odlulayo, kodwa ayikwazi ukuvimba ugesi we-short-circuit. Iswishi yokulayisha ingavula futhi ivale ugesi wokulayisha,...

Izintambo zikagesi zisetshenziselwa ukudlulisa nokusabalalisa amandla kagesi anamandla amakhulu. Ngokwezinto ezahlukene zokuvimbela ukushisa, zingahlukaniswa zibe izintambo zikagesi ezifakwe uwoyela ezifakwe ephepheni, izintambo zikagesi ezifakwe irabha kanye nezintambo zikagesi ezifakwe i-PVC. Ezisetshenziswa kakhulu kwezobunjiniyela yi...

Okuyisisekelo Ekusetshenzisweni kwawo wonke amabhlogo wokugcina, amabhlogo wokugcina wesitayela saseYurophu anezinzuzo zokusetshenziswa. Isihluthulelo ukuthi awagcini nje ngokuba nomoya ophezulu ngesikhathi senqubo yonke yokusebenzisa, kodwa futhi anesiqinisekiso esiphezulu sesici sokuphepha, kodwa uma kuqhathaniswa namanye amabhlogo wokugcina,...

Iswishi yomthwalo ene-high-voltage isetshenziselwa ukuphula i-load current (kufaka phakathi i-overload current ejwayelekile) esebenza, futhi inekhono elithile lokulungisa i-photosynthesis short-circuit current kanye nokuqina kokushisa. Ivame ukusetshenziswa kanye nama-fuse ohlelweni lwamandla. Iswishi yomthwalo isetshenziswa...

I-Fuse ibizwa nangokuthi i-fuse, melt. I-fuse ephelele yokuhlala ifakwa ngemuva kwemitha yamandla kagesi, kanti i-fuse ye-porcelain plug-in isetshenziswa ngokuvamile. Manje njengokuvikela okuphelele kwendlu, ama-circuit breaker avame ukusetshenziswa esikhundleni sama-fuse. Ama-workshop abantu ngabanye basemadolobheni nasemaphandleni, amadolobha amadala ...

Ama-fuse ane-voltage ephezulu ngokuvamile asetshenziswa kuma-grid kagesi amancane ane-voltage engaphansi kuka-35kV. Uma kwenzeka ukugcwala ngokweqile noma i-short circuit ohlelweni, ukuncibilika kuyapheshulwa ngenxa yokushisa ngokweqile, ngaleyo ndlela kunqamule umugqa futhi kuvikele i-grid kagesi kanye nemishini kagesi. Isimiso sayo sokusebenza...

Iswishi yomthwalo we-high-voltage iyithuluzi likagesi elihlanganisiwe elinomthamo ophezulu, eliqukethe iswishi yokuhlukanisa, i-fuse, i-thermal relay, i-shunt release kanye nedivayisi yokucisha i-arc. Iswishi yomthwalo we-high-voltage inedivayisi elula yokucisha i-arc, engasetshenziswa kuphela ukwenza nokukhiqiza...

1. Ngokwendlela yokufaka i-circuit breaker (1) Uhlobo olususwayo noma uhlobo lwenqola yesandla (olumelelwe u-Y) Kusho ukuthi izingxenye zikagesi eziyinhloko (njengezi-circuit breaker) ekhabhinethi zifakwe enqoleni yesandla edonsekayo. Ngenxa yokuthi ikhabhinethi yenqola yesandla inokushintshaniswa okuhle,...

Izivikelo ezinhlanu zeswitshi ye-voltage ephezulu 1. Ngemva kokuba i-trolley ye-vacuum circuit breaker ekhabhinethini yeswitshi ye-voltage ephezulu ivaliwe endaweni yokuhlola, i-trolley circuit breaker ayikwazi ukungena endaweni yokusebenza. (ukuvimbela ukuvala ngomthwalo) 2. Lapho ummese wokumisa endaweni ye-voltage ephezulu ushintsha...
