Iinkcukacha zeMveliso

Iithegi zeMveliso

Inkcazo emfutshane yemveliso:

I-breaker esebenzise i-vacuum njenge-arc extinction medium ibizwa ngokuba yi-vacuum circuit breaker.I-vacuum circuit breaker ine-high insulating medium yokuphela kwe-arc xa kuthelekiswa nenye i-breaker circuit.Xa i-arc ivuliwe ngokuhambisa ngaphandle abafowunelwa kwi-vacuum, ukuphazamiseka kwenzeka kwi-zero yokuqala yangoku.Ngokuphazamiseka kwe-arc, amandla abo e-dielectric anyuka ukuya kuthi ga kwisantya samawakawaka xa kuthelekiswa nezinye izaphuli.
Kulula kakhulu ekwakhiweni xa kuthelekiswa nayiphi na enye i-breaker circuit.Ukwakhiwa kwabo ngokuyinhloko kuhlulwe kumacandelo amathathu, oko kukuthi, abafowunelwa abasisigxina, ukudibanisa okuhambayo kunye ne-arc shield efakwe ngaphakathi kwegumbi lokuphazamisa i-arc.
Ukunqunyulwa kwangoku kwi-vacuum circuit breaker kuxhomekeke kuxinzelelo lomphunga kunye neempawu zokukhutshwa kwe-electron yezinto zoqhagamshelwano.Inqanaba lokunqunqa liphinde liphenjelelwe yi-thermal conductivity-ezantsi i-thermal conductivity, ephantsi yinqanaba lokusika.

Qwalasela

Amanyathelo okuthintela ukugqithiswa kwamandla.I-vacuum circuit breaker inomsebenzi omhle wokuqhawula.Ngamanye amaxesha xa kuphulwa umthwalo wokufakelwa, ukugqithisa okuphezulu kuveliswa kuzo zombini iziphelo ze-inductance ngenxa yokutshintsha ngokukhawuleza kwe-loop yangoku.Ngoko ke, kwii-transformers zohlobo olomileyo kunye nezinye izixhobo ezinokumelana nombane ophantsi we-impulse, kungcono ukufaka izixhobo zokukhusela i-overvoltage, ezifana ne-metal oxide arresters.
