Umsebenzi we-High Voltage Circuit Breaker

I-circuit breaker into esebenza ngogesi kusistimu yamandla, enganqamuka ngokuzenzakalelayo lapho ulayini noma isiteshi esincane sisiyingi esifushane noma silayisha ngokweqile ukuze kuvikelwe okokusebenza kwamandla nokuphepha komuntu siqu.
I-high voltage circuit breakerikakhulukazi yakhiwe isistimu yokucisha i-arc, isistimu ephazamisayo, idivayisi yokulawula kanye nesici sokuqapha.
Uma iswishi ingakwazi ukunqanyulwa ngesikhathi, idivayisi kagesi noma ingxenye ye-elekthronikhi izonqamula indawo enephutha ngokuzenzakalelayo ukuze kuvikelwe ukuphepha komuntu siqu kanye nokuphepha kwezinto zokusebenza.

I, isistimu yokucisha i-arc
Isistimu yokucima i-arc ye-high voltage circuit breaker ihlanganisa idivayisi ekhiqiza i-arc, idivayisi yokucima i-arc negumbi lokucima i-arc.
Kusistimu ye-voltage ephansi, ngokuvamile isebenzisa isiphazamisi somoya ukucisha i-arc, ngoba isiphazamisi somoya asinawo amandla kagesi, ngakho-ke asikwazi ukuba ne-arc yokukhiqiza.
Kuhlelo lwamandla kagesi aphezulu, ukucisha i-arc ye-vacuum kuvame ukusetshenziswa, kusetshenziswa umphumela oshisayo namandla kazibuthe kagesi wegumbi lokucisha le-vacuum arc lamanje.
Kumasekhethi e-HVDC, ukucisha i-arc kuvame ukwenziwa ngokukhipha imishini ngenxa ye-DC enkulu yamanje nokuvela kalula kokuqhuma kwe-arc.
Ngenxa yomthamo omkhulu we-high voltage circuit breaker, igumbi lokucisha i-air arc lisetshenziswa kakhulu.
II, Isistimu yokunqanyulwa
I-breaker ye-high voltage circuit breaker ikakhulukazi ihlanganisa i-electromagnetic, ikhoyili kagesi, njll.
Umsebenzi kazibuthe kagesi ukukhiqiza insimu kazibuthe ecindezela i-arc ngokumelene nejoka.
Umsebenzi wekhoyili kazibuthe ukuthumela isignali yokushaya kwenhliziyo lapho iswishi ivuliwe noma ivaliwe kusilawuli, futhi isilawuli siqedela umsebenzi wokunqamula ngokulawula ikhoyili kazibuthe ukuze uvule noma uvale.
Ikhoyili ye-electromagnetic nayo isebenza njengokuhlukaniswa kwe-electromagnetic.
Ijoka libekwe phezu kwe-circuit breaker, okubangela ukuthi i-arc voltage ikhiqize insimu kazibuthe ejokeni, ehlinzekwa yipheya yezikhali ezizungezisayo ezizungezayo, ngaleyo ndlela ivimbele i-arc ukuthi ingathwalwa isuka esekethe ngejoka futhi ibangele ingozi.
III, Lawula amadivayisi
Ama-Circuit breaker ngokuvamile asebenzisa amathuluzi okulawula akhethekile, njengama-microcomputer circuit breaker (amadivaysi okuvikela amakhompyutha amancane), anokulawula nokuvikela.
Umsebenzi wedivayisi yokuvikela i-microcomputer ukukhiqiza isignali ye-voltage noma yamanje kusekethe uma kunephutha, bese uyiguqula ibe isignali kagesi noma isignali ye-pulse ngokusebenzisa i-amplifying circuit, futhi uqaphele umsebenzi wokusebenza kwe-circuit breaker ngokusebenzisa i-relay noma ezinye izinto zokulawula ( njenge-reactor, isolator, njll.).
Ngaphezu kwalokho, kukhona ukushintsha kwemishini okusetshenziselwa ukusebenza kokushintsha kokulawula okuzenzakalelayo, njenge-SCR, ama-SCR rectifier diode, njll.
Ukuze kuthuthukiswe ukuthembeka nokuphepha, amadivayisi okuvikela amakhompuyutha amancane avame ukusebenzisa izinto ezikhiphayo ze-analog ukuze anikeze imisebenzi yokuvikela eyengeziwe, efana ne-analog input/output (AFD), inhlanganisela ye-voltage/current (AVR) noma isampuli yamandla kagesi we-transformer yamanje.
IV, Izingxenye zokuqapha
I-circuit breaker ifakwe isethi yezingxenye zokuqapha ezizenzakalelayo, ezisetshenziselwa kakhulu ukuthola isimo esingavamile ngesikhathi sokuphulwa kwe-circuit breaker.
Ama-circuit breaker ajwayelekile aphezulu yi-SF6, SF7, vacuum nezinye izinhlobo, ngokusho kwezinhlobo ezahlukene zingahlukaniswa ngama-voltage akaliwe 1000V, 1100V kanye no-2000V.
Ngokuthuthuka kwesayensi nobuchwepheshe, ama-circuit breaker e-HV avuselelwa njalo.Njengamanje, i-SF6 circuit breaker kanye ne-SF7 circuit breaker isetshenziswa kabanzi ezweni lakithi.
V, Izidingo zokufakwa kanye nezinyathelo zokuphepha zama-high voltage circuit breaker
Lapho ufaka i-high voltage circuit breaker, ukunakwa kufanele kukhokhwe ukuphakama kwendawo yokufaka kanye nebanga;imodi ye-wiring ehambisanayo izokhethwa ku-breaker circuit ngokusho kwezinga le-voltage kanye nezinga elifushane lesifunda samanje.
Ukuze ugweme izinkinga ezinjengomphumela oshisayo kanye nomphumela we-electromagnetic lapho kwenzeka isifunda esifushane, kufanele kuqashelwe ukuthi indawo yokufaka i-breaker circuit izoba kude nesikhungo sokulayisha ngangokunokwenzeka;ngesikhathi sokufakwa, kuzoqinisekiswa ukuthi i-high-voltage circuit breaker ingashajwa kalula kusuka kudivayisi yokusabalalisa amandla, futhi indlela yokusebenza ye-circuit breaker izoba nesikhala esanele sokunyakaza;futhi isikhundla sendlela yokusebenza ye-breaker circuit sizoba lula ukuhlukanisa ukunikezwa kwamandla okusebenzayo kumandla okusebenza.
