Izilumkiso zeSeries Resonance Test System

Izilumkiso zeSeries Resonance Test System

1. Ngethuba lovavanyo, isigaba sovavanyo sixhunywe kumthombo we-voltage ephezulu, kwaye i-high-voltage lead wire kufuneka isebenzise i-halo-free lead wire, kwaye isigaba esingenalo uvavanyo sisekelwe kwigobolondo ye-GIS;

2. Uvavanyo maluqinisekise ukuba igesi ye-SF6 kwigumbi ngalinye legesi iphantsi koxinzelelo olulinganisiweyo, kwaye umxholo wegesi ungaphakathi koluhlu olwamkelekileyo emva kweeyure ezi-4 zoxinzelelo lokunyuka kwamaxabiso, kwaye i-GIS ikwimeko esebenzayo.Uvavanyo lunokwenziwa kuphela emva kokuqinisekiswa;

3. Ngaphambi kokuba ucinezele uvavanyo, qinisekisa ukuba i-voltage transformer kwi-GIS isusiwe (ukuba umenzi we-GIS uyavuma, i-voltage transformer inokunyanzeliswa kunye, kodwa i-resonant frequency test kufuneka ibe mkhulu kune-100Hz), i-CT second circuit short circuit, kwaye uqhagamshelo lombambi kufuneka luqhawulwe;

4. I-voltage yokuvavanya yongezwa kwi-output bushing, i-bushing core ixhunyiwe kumthombo ophezulu we-voltage, kwaye i-metal bushing ixhunyiwe kwi-wire ekhethekileyo yomhlaba wenkqubo;

5. Ngethuba lovavanyo, iingcingo ezikhethekileyo zomhlaba kufuneka zisetyenziswe phakathi kwamacandelo enkqubo yovavanyo kunye naphakathi kwenkqubo yovavanyo kunye negobolondo le-GIS, kwaye i-ground bar ekwisiza mayingasetyenziselwa ukutshintsha uxhulumaniso lwecingo lomhlaba phakathi kwenkqubo yovavanyo. kunye neqokobhe leGIS;

6. Nika ingqalelo uxhulumaniso lwenqaku elinye phakathi kwenkqubo yokuvavanya kunye negridi yamandla kwisayithi, kwaye indawo yokumisa kufuneka ibekwe kumgca wokudibanisa phakathi kwe-voltage divider kunye nento yokuvavanya;

Umgaqo kunye nemibandela efuna ingqalelo yovavanyo lwesicelo se-transformer yangaphandle

Uvavanyo olusetyenzisiweyo lwangaphandle luvavanyo olusisiseko lokuvavanya i-insulation ephambili ye-transformer, kwaye i-frequency yokuvavanya ayiyi kuba ngaphantsi kwe-80% ye-frequency elinganisiweyo;

Ingqalelo kuvavanyo lwesicelo sangaphandle se-transformer:

1. Zomibini i-winding evavanyiweyo kunye ne-non-test winding i-short-circuited, kunye ne-non-test winding isekelwe emva kokujikeleza okufutshane.Ngokomgaqo, imveliso yovavanyo akufuneki ibe nokunqunyanyiswa okunokwenzeka;

2. Ngethuba lovavanyo, uxhulumaniso phakathi kwenkqubo yokuguqulwa kwe-resonant kunye negobolondo ye-transformer evavanyiweyo ithatha ucingo olukhethekileyo lomhlaba olunikezwa yinkampani;
