Iswitshi ye-voltage ephezulu isetyenziselwa iimveliso zombane ezinenqanaba le-voltage ye-3.6kV ~ 550kV, i-voltage ephezulu...

Umsebenzi ophambili webhokisi yesebe lentambo kukwahlulahlula okanye ukutshintsha iintambo. Ukuqhawuka kweentambo. Ukuthwala iintambo ezininzi ezincinci kwindawo yonke kwindlela enomgama omde kudla ngokukhokelela ekugqithiseni nasekuchitheni ukusetyenziswa kweentambo, ngoko ke xa umthwalo wamandla ungangeni ndawo, ipali ephambili kunye neentambo ezinkulu...

Umgaqo wefusi yamandla Ifusi yamandla yenye yeefusi, ebhekisa kwisixhobo sombane esidibanisa ukunyibilika nobushushu obuveliswa bubodwa kwaye sinqamule isekethe xa umbane udlula ixabiso elithile. Ifusi sisikhuseli samandla esenziwe ngokusebenzisa ubushushu obuveliswa yi...

Iswitshi yomthwalo sisixhobo sokutshintsha phakathi kwe-circuit breaker kunye ne-isolation switch. Inezixhobo ezilula zokucima i-arc, ezinokuthintela i-load current eyongezelelweyo kunye ne-overload current ethile, kodwa azinakuthintela i-short-circuit current. Iswitshi yomthwalo ingavula kwaye ivale i-load current,...

Iintambo zombane zisetyenziselwa ukudlulisa nokusasaza amandla ombane anamandla aphezulu. Ngokwezixhobo ezahlukeneyo zokukhusela ubushushu, zinokwahlulwa zibe ziintambo zombane ezifakwe ioyile ephepheni, iintambo zombane ezifakwe irabha kunye neentambo zombane ezifakwe i-PVC. Ezona zisetyenziswa kakhulu kubunjineli yi...

Izinto ezisisiseko Ekusetyenzisweni kwazo zonke iibhloko zesiphelo, iibhloko zesiphelo zesitayile saseYurophu zinezibonelelo zokusetyenziswa. Eyona nto ibalulekileyo kukuba azigcini nje ngokuba nomoya ophezulu ngexesha lonke lenkqubo yokusetyenziswa, kodwa zikwanaso nesiqinisekiso esiphezulu sento yokhuseleko, kodwa xa kuthelekiswa nezinye iibhloko zesiphelo,...

Iswitshi yomthwalo ene-high-voltage isetyenziselwa ukwaphula i-load current (kuquka i-regular overload current) esebenzayo, kwaye inamandla athile okulungisa i-photosynthesis short-circuit current kunye nozinzo lobushushu. Ihlala isetyenziswa kunye nee-fuses kwinkqubo yamandla. Iswitshi yomthwalo isetyenziswa...

I-Fuse ikwabizwa ngokuba yi-fuse, melt. I-fuse epheleleyo yokuhlala ifakwa emva kwemitha yamandla ombane, kwaye i-fuse ye-porcelain plug-in isetyenziswa ngokubanzi. Ngoku njengokhuseleko olupheleleyo lwendlu, ii-circuit breakers zihlala zisetyenziswa endaweni yee-fuses. Iiworkshops zomntu ngamnye zasezidolophini nezasemaphandleni, izixeko ezindala ...

Iifusi ze-high-voltage zihlala zisetyenziswa kwiigridi zamandla ezinomthamo omncinci ezine-voltage engaphantsi kwe-35kV. Xa kwenzeka i-overload okanye i-short circuit kwinkqubo, i-melt iyavuthuzwa ngenxa yokushisa kakhulu, ngaloo ndlela inqumla umgca kwaye ikhusele igridi yamandla kunye nezixhobo zombane. Isiseko sayo sokusebenza...

Iswitshi yomthwalo we-high-voltage sisixhobo sombane esidibeneyo esine-high-voltage, esiqulethwe yiswitshi yokwahlukanisa, i-fuse, i-thermal relay, i-shunt release kunye nesixhobo sokucima i-arc. Iswitshi yomthwalo we-high-voltage inesixhobo esilula sokucima i-arc, esinokusetyenziselwa kuphela ukwenza nokuvelisa...

1. Ngokwendlela yokufaka i-circuit breaker (1) Uhlobo olususwayo okanye uhlobo lwenqwelo ephathwayo (emelwe ngu-Y) Kuthetha ukuba izinto eziphambili zombane (ezifana ne-circuit breakers) kwikhabhinethi zifakwe kwinqwelo ephathwayo etsalwayo. Ngenxa yokuba ikhabhinethi yenqwelo ephathwayo inokutshintshwa kakuhle,...

Izixhobo zokuzikhusela ezintlanu zeswitshi ye-voltage ephezulu 1. Emva kokuba itroli ye-vacuum circuit breaker kwikhabhinethi yeswitshi ye-voltage ephezulu ivaliwe kwindawo yovavanyo, i-trolley circuit breaker ayinakungena kwindawo yokusebenza. (ukuthintela ukuvalwa ngomthwalo) 2. Xa imela yokumisa kwi-high-voltage swi...
