LZZBJ9-10 current transformer is an indoor epoxy resin cast pillar-type all-working-condition product. It is used for current, energy measurement or relay protection in power systems with a rated frequency of 50Hz and a rated voltage of 10kV and below. It is suitable for center-mounted switches. cabinets and other types of switch cabinets.
LZZBJ9-10 current transformer has a fully enclosed structure. The iron core is made of high-quality magnetic conductive materials. The primary and secondary windings and iron core are all cast in epoxy resin. It has excellent insulation performance and moisture-proof ability, and is easy to Surface clean.
The primary outlet P1 and P2 are at the top of the pouring body respectively, and the secondary winding outlet end is at the lower part of the pouring body. The first group is the metering winding (0.2S level, 0.2 level), marked 1S1, 1S2: the second group is the monitoring winding. (Level 0.5), marked as 2S1, 2S2: The third group is the protection level winding (10P), marked as 3S1, 3S2, and the secondary winding can be tapped.
