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 andsoltaqe 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.
