Ngaba uyaluqonda ngokwenene utshintsho lokutshintsha?–AISO

Yintoni iukwahlula iswitshi

 Iswitshi yokwahlulahlula,eyaziwa ngokuba iswitsha imela, luhlobo lokutshintsha high-voltage.Ayinasixhobo sokucima i-arc.Xa ikwindawo evaliweyo, inokuthwala umbane osebenzayo, kodwa ayinakusetyenziselwa ukudibanisa okanye ukunqumla umthwalo wangoku kunye nombane omfutshane.Kufuneka usebenzisane ne-circuit breaker.

2. Injongo yeukwahlula iswitshi

 2.1 I-voltage ye-Isolation: Ngexesha lokugcinwa, izixhobo zombane zihlukanisiwe kwigridi yamandla esebenzayo kunye nokutshintsha okukodwa ukwenza i-gap ecacileyo yokuqhawula, ukwenzela ukuba kuqinisekiswe ukhuseleko lokusebenza kunye nokugcinwa.

2.2 Umsebenzi wokuvala: tshintshela ibhasi yokugcina okanye i-bypass ibhasi kwaye utshintshe indlela yokusebenza, sebenzisa iswitshi yokuhlukanisa kunye ne-breaker circuit ukugqiba.

 Kwimowudi yokudibanisa i-busbar ephindwe kabini, into yokudibanisa iyatshintshwa phakathi kweebhasi ezimbini ngokusebenzisa i-on-off yendawo yokutshintsha yodwa kwiibhasi ezimbini.

 2.3 Ukuvula kunye nokucima isiphaluka esincinci sangoku: Umtshini wokuhlukanisa unamandla athile okuvula kunye nokucima i-inductive current kunye ne-capacitive current.Iswitshi yokwahlula ingasetyenziselwa le misebenzi ilandelayo ngexesha lokusebenza:

 ①.Ingasetyenziselwa ukudibanisa kunye nokuqhawula i-voltage transformers kunye nokubamba.

 ②.Qhagamshela kwaye uqhawule imigca yothungelwano olungenamthwalo kunye nombane we-capacitance ongadlulanga kwi-5A, i-voltage ye-10kV, kunye nomgca wothumelo ongekho mthwalo kunye nobude obungaphantsi kwe-5km kunye nomgca wokuhambisa okungekho mthwalo kunye ne-voltage ye-35kV kunye nobude. ngaphantsi kwe-10km.

 ③.Vula kwaye ucime i-transformer engalayishiyo ekhoyo ngoku i-excitation ingekho ngaphezu kwe-2A: iklasi ye-35kV ingaphantsi kwe-1000kVA, kwaye iklasi ye-110kV ingaphantsi kwe-3200kVA.

 2.4 Ukuzihlukanisa ngokuzenzekelayo kunye nokukhawuleza: Phantsi kweemeko ezithile, unokukhawuleza ukuhlukanisa izixhobo kunye nemigca engaphumeleli ukuphumeza injongo yokugcina inani lee-circuit breakers.

Ukuba unombuzos okanye nayiphi na imveliso efunekayo, nceda uzive ukhululekile ukuba uqhagamshelane nam.
