LA-10(LFZ1-10,LFZB1-10) 10kv indoor wall through current transformer /Mutual inductor
LA-10 current transformer is sen I-sealed structure with resin casted insulation and fuII-sealed indoor installment product with resin casted insulation for the us of measurement of current and electronic energy and relay protection at frequency of 50Hz and soltaqe of 10kv below.
Construction
The current trarsformer is semi-sealed structure 200A beIow and full-concealed resin casted insulation sturcfu re over 300A.
The semi-conceaied resin casted insuIation product is of foIded-sliced dou ble ring core with prlmary winding and secondary winding The resin is casted bet ween the two winding wives The secondary winding and core are insulated by glassboard with core eaposed.
The full-sealed resin casted insuIation product is of an anneaIed tina core wound with secondary wlndina The prlbary is single-furn through copper stick The primary and the secondary are casted with the core as a whole body insulation casting body is fixed on the flange which rating plate,warning plate ea rthing volts and holds for mounting are on.
`The lead code:The prmary is P1,P2 and the secondary 1S1,1S2(a5 class)2S1,2S2(10p class)when the primary current flons to P2throuqh P1 and the secondary flows back to S2 through S1 which is polar reduce.when the current is through the prlmary.the secondary can not be open in case of high-tenston current.
Technical data
1. The current transformer can keep working at rate current of 1.1multiple.
2. Power frequency testing voltage: between the primary and secondary t earthing of voltage 2kv ,for duration of 1min.
