Overview
LZZBJ9-10 current transformer is an epoxy resin vacuum casting pillar structure, which is applicable to power lines and equipment with rated frequency of 50HZ and rated voltage of 10KV and below for current and energy measurement and relay protection.
Structural characteristics
LZZBJ9-10 current transformer is composed of epoxy resin, and its iron core is made of high-quality magnetic materials. 1、 The secondary winding and iron core are all cast in epoxy resin, the product surface is not sprayed, with excellent insulation and moisture resistance, and the surface is easy to clean. The primary outlet terminal is on the top of the casting body, and the outlet terminal marks are P1 and P2. The first secondary winding is the measuring stage, and the outlet terminal marks are 1S1 and 1S2; The second secondary outlet terminal is marked with protection level, and the outlet terminals are marked with 2S1 and 2S2. The transformer is connected in a reduced polarity. There are grounding bolts and four mounting holes on the base.
