Izixhobo/iivalvu zokunciphisa uxinzelelo zihlala zihlelwa kwi Ishishini le-transformer njengezixhobo zokhuseleko okanye zokukhusela isixhobo sokunceda uxinzelelo lwetransformer Ivalvu yeetransformer ezintywilisiweyo ngamanzi ivuliwe xa kukho isiphene sangaphakathi kwaye iqinisekisa ukuba uxinzelelo olugqithisileyo olwenzekileyo lunokukhululwa ngokufanelekileyo. Iivalvu zesixhobo sokunceda uxinzelelo kwiitransformer ezivala ngoxinzelelo olunciphayo lubuyela kwindawo evaliweyo neqinileyo. Iivalvu zesixhobo sokunceda uxinzelelo kwiitransformer zinokufakwa kuyo nayiphi na indawo okanye ukuthambekela kwisiciko okanye eludongeni lwetransformer. Xa iceliwe, itransformer inokuxhotyiswa ngeevalvu ezininzi zokunceda uxinzelelo. Iivalvu zokunceda uxinzelelo ziyavavanywa ukuba zisebenza na. Ukusetyenziswa kwezi zixhobo kukunciphisa ukunyuka ngequbuliso koxinzelelo lweoyile, ngaphakathi kwitanki yeTransformer epholisiweyo yioyile ephefumla ngokukhululekileyo.

Xa i-transformer entywilisiweyo kwioyile isiphene sangaphakathi esifana ne-short circuit, itanki ivelisa inani elikhulu legesi，ukuze uxinzelelo olungaphakathi kwitanki lunyuke kakhulu, ivalvu yokunciphisa uxinzelelo inokukhulula uxinzelelo oluveliswa ngaphakathi kweemilimitha ezi-2, kwaye xa uxinzelelo luyehla luye kwivalvu ukuze luvale uxinzelelo, ivalvu ivalwa ngokuthembekileyo, ukuze kukhuselwe itanki yetransformer entywilisiweyo kwioyile.

Umgaqo wokusebenza we isiqabu kuxinzelelo lwe-transformer ivalvu Kulula kakhulu. Ukuba uxinzelelo luvela ngaphakathi kwitransformer kwaye ludlule umda woxinzelelo obekwe kwangaphambili, ivalvu yokhuseleko loxinzelelo ivula ivalvu yayo ebambekileyo, ebanjwe sisipringi kwaye ikhuphe uxinzelelo lwangaphakathi ide yehle. Emva kokwehla koxinzelelo, ivalvu yoxinzelelo ibuyela kwindawo yayo yokuqala kwaye ivale ngokupheleleyo. Ngokwesiqhelo, isixhobo sokunciphisa uxinzelelo siya kuxhonywa phezu kwetransformer. Ngenxa yeziphene zangaphakathi, kucetyiswa ukuba kubekho ezinjalo. iivalvu zokunceda uxinzelelo ukukhusela i-transformer nokukhulula uxinzelelo oluvelayo ngequbuliso.

Simele senze ntoni ukuba I-PRV uhambo nge-transformer?

Ivalvu Yokunciphisa Uxinzelelo (i-PRV) Uxinzelelo lwegesi luyanda kwi-transformer ngenxa yezizathu ezibini. (1) I-transformer igcwele kakhulu kwaye (2) kukho impazamo ethile kwi-transformer.

Xa i-transformer igcwele kakhulu, ukujija kuyatshisa kwaye ioyile yanda kuloo bushushu. Ioyile iya phezulu iye kwi-oyile conservator. Oku kwenza indawo yegesi kwi-conservator ibe ncinci kwaye ngaloo ndlela uxinzelelo luyanda.

Xa kukho isiphene somhlaba okanye isiphene sesigaba ukuya kwesinye kwi-transformer kuya kubakho ubushushu obukhulu kwaye ngenxa yesi sizathu, iigesi ze-methane, i-ethane, i-acetylene, njl.njl. ziya kwakheka ngokugquma iphepha kunye neoyile ngokulandelelana ngokukhawuleza. Emva koko, i-PRV iya kukhubeka.

Ngoko ke isicwangciso sokusebenza siza kuba kukuqonda ukuba kukho impazamo kwi-transformer okanye igcwele kakhulu. Jonga ukufundwa kwangoku ukuze uqonde imeko yokulayisha kwaye ukuba igcwele kakhulu, yehlisa umthwalo. Ukuba kukho impazamo kwi-transformer, awunandlela ngaphandle kokulungisa.
