Khetha [Uvavanyo]-[Vala], kukho isiboniso sexesha lokwenyani leezaphulelo ezili-12 ngaphantsi kwesikrini se-LCD somvavanyi weempawu ze-high-voltage.Isikrini sibonisa ukuba phantsi kolu jongano, unokujonga ukuba itshaneli yokuphuka kwesixhobo ikwimeko entle.Ukuba igalelo lefracture liyadada, kufuneka libonise "Vula", kwaye ukuba lifutshane-lijikeleza emhlabeni, kufuneka libonise "Vala".Ngoko ke, i-short-circuit i-fracture nganye phantsi kwaye ugcine umboniso wesimo ukuze ubone ukuba ishaneli yexesha lokuphuka kwe-Circuit Breaker Tester iyinto eqhelekileyo.
HV HipotGDKC series Circuit Breaker Tester
I-HV Hipot iya kukuphendulela ukuba iswitshi yevoltage ephezulu ikwanayo nesantya esiqinileyo sokwahlula (ekufutshane) esichazwa ngumenzi, ikakhulu kwezi ndidi zilandelayo:
1. Thatha isantya esiphakathi kwenkqubo yonke yokuvala, kwaye uthathe isantya esiphakathi kwe-6mm emva nje kokuvula;
2. Thatha umyinge wesantya senkqubo yonke yokuvala, kwaye uthathe isantya esiphakathi senkqubo yonke yokuvula;
Ichazwa njengenkcazo yesantya eyongeza umsebenzi weprogram ngaphambi nje kokuvala (nje emva kokuvula), enokuthi iququzelele uvavanyo lwesantya ngokuhambelana nokutshintsha okucacileyo kwe-vacuum.Ukongeza, xa uvavanyo lwesantya sokutshintsha kwe-vacuum lwenziwa, isantya esiphakathi kwayo yonke inkqubo yokuvula siphantsi kakhulu ngenxa yomsebenzi wesixhobo se-buffer ngexesha lokuvula.Kuchazwa ngokubanzi ukuba isantya esiphakathi somatshini wokuvala phambi kokuba isixhobo sesithinteli sisebenze ngexesha lokuvula iswitshi yevacuum sisantya esiphakathi senkqubo yonke, oko kukuthi, isantya esiphakathi sokuvala sithathwa njengenkqubo yonke. i-avareji, kunye nesantya esiphakathi kwe-6mm nje emva kokuvula kusondele kwixabiso lokwenene.Ekubeni umgama wokuvula we-35KV vacuum switch ngokubanzi malunga ne-S = 22mm, ixabiso le-6 kuzo zonke iinkcazo ezingasentla ze-10KV isantya sokutshintsha i-vacuum inokutshintshwa ukuya kwi-10 okanye i-11.
Kuchazwa njengendawo yokumisa indawo ngaphambi kokuba kuvalwe (ngemva nje kokuqhekeka), nikela ingqalelo kucingo lokumisa kuqala, uze udibanise ucingo lokuphuka ukuze uqinisekise ukhuseleko lomjelo wokuqhekeka.
Ngexesha lovavanyo ebaleni, kuba kudla ngokubakho amandla ombane aphezulu phakathi kokuqhekeka kweswitshi ephezulu yombane (ingakumbi ngaphezulu kwe-220kV) kunye nomhlaba, lo mbane mkhulu ngobukhulu kwaye uncinci kumandla, kodwa kwanele ukusongela ukhuseleko. ye-high-voltage iswitshi eguqukayo umvavanyi uphawu ngokwayo..Ngaphakathi kwesixhobo, isiphaluka soncedo sidibaniswe phakathi kwe-terminal yokufakwa kwesignali ye-fracture kunye nomhlaba.Ucingo lomhlaba luqala, kwaye isiphaluka soncedo ngokwenene siqhagamshelwe kuqala.Ngeli xesha, xa umgca wesignali we-fracture udibaniswe, nokuba i-voltage ephezulu ibangelwa yi-fracture, inokukhutshwa emhlabeni ngokusebenzisa isiphaluka soncedo, ngaloo ndlela iqinisekisa i-Circuit Breaker Tester.Ukhuseleko lomjelo wokuqhekeka.
