I-110kV yokuntywiliselwa kwe-oyile yaNgaphandle eGuquliweyo yaNgoku eFakelweyo nguMfanekiso

I-110kV ye-Oli yokuntywiliselwa ngaphandle kweSiguquli sangoku esiGuquliweyo

Inkcazelo emfutshane:

Ukusetyenziswa kweMveliso

I-oyile yangaphandle yesigaba esisodwa se-oil-immersed inverted current transformer, esetyenziselwa okwangoku, ukulinganisa amandla kunye nokukhuselwa kwe-relay kwi-35 ~ 220kV, i-50 okanye i-60Hz iinkqubo zamandla.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Imiqathango yokusetyenziswa

◆ Ubushushu be-Ambient: -40～+45℃
◆Ukuphakama: ≤1000m
◆Inqanaba longcoliseko: Ⅱ, Ⅲ, Ⅳ

Iimpawu zoLwakhiwo

◆Le mveliso yi-inverted oil-paper insulation structure.I-insulation engundoqo yenziwe nge-high-voltage cable paper wrapping.Ukuze kuphuculwe ukuhanjiswa kwentsimi yombane kunye nesantya sokusetyenziswa kwezinto zokugquma, izikrini ezininzi ze-capacitive zokulinganisa amandla ombane zisetiwe kwi-insulation engundoqo, entywiliselwa kwi-oyile ye-transformer emva kokumisa i-vacuum, kwaye akukho nxalenye phantsi kwamandla amaninzi.ukukhupha.Ukusebenza kwe-insulation kuzinzile kwaye kunokwethenjelwa, amava okusebenza atyebileyo, kwaye ubomi benkonzo bude.
◆Iyona ndlela iphambili yokujija isakhelo sodidi lwe-conductive rod, ephucula ukukwazi kwemveliso ukumelana nomsinga omfutshane;Uzinzo oluphezulu lwexabiso langoku lwe-thermal yi-63kA/3s (xa i-primary winding idityanisiwe kuthotho)
◆I-winding yesibini ifakwe kwiqokobhe le-aluminiyam ekhuselayo kunye nezinto eziphilayo, kwaye imigca yokulinganisa kunye nokukhusela kwicala lesibini ayiyi kuhlaselwa ngumbane ngenxa yokuphazamiseka kwe-insulation.
◆ Isixokelelwano esizenzekelayo esizenzekelayo sokumisa i-vacuum kunye nenkqubo yokumisa i-vacuum ephezulu kunye nenkqubo yokutofa kwe-oyile iqinisekisa ukuba iyonke i-dielectric loss factor tanδ yemveliso ingaphantsi kwe-0.4%
◆Isigqubuthelo sangaphandle samkela uyilo oluphuculweyo ukwenza indawo yombane ngaphakathi nangaphandle nangaphandle kokuphuma.Kukho iintlobo ezimbini zokukhetha abasebenzisi:
1. I-insulator ehlanganisiweyo
2. Umkhono ophezulu we-porcelain
◆Itheminali yesibini yocingo lomsebenzisi isebenzisa i-Phoenix ekhethekileyo.Imisebenzi yokuplaga, ukukhupha iiplagi kunye ne-wiring kulula ngakumbi kwaye iyakhawuleza.
◆ I-Sub-arc welding isetyenziselwa ukudibanisa phakathi kwamacandelo emveliso, kwaye yonke indibano izaliswe nge-nitrogen ephezulu yoxinzelelo lokubona ukuvuza, nto leyo isombulula ingxaki yokuvuza kweoyile yeemveliso ezintywiliselwe ngeoyile.
◆ Umphezulu wemveliso uxhotyiswe nge-expander yensimbi engenasici, egcina imveliso kwindawo etywinwe ngokupheleleyo, ikhusela ioli ye-transformer kunye ne-insulating paper ukuba ibe manzi, kunye nokwandisa ubomi benkonzo yemveliso, kunye nokuhlolwa kwenqanaba leoli. ifestile ibekwe kwi-expander yensimbi, enokuthi ibonwe ngokulula.Utshintsho kwinqanaba leoli.
◆Zonke iindawo ezikhuselayo zale mveliso zenziwe ngezinto ezinobungani nokusingqongileyo.
◆ Umzantsi wemveliso uxhotyiswe ngevalve ye-oyile enemisebenzi emininzi, eyenza kube lula ukuthatha iisampulu zeoyile kunye nokukhupha ioyile.
◆Amalungu entsimbi avuzayo angaphandle anje ngesiseko kunye nebhokisi yejunction amkele iinkqubo ezimbini zokuchasa umhlwa zokutshiza kunye ne-hot-dip galvanizing, ezintle kwaye zinentsebenzo entle yokuchasana nomhlwa.
