Product Description

LZZJ-10Q Casting Resin Epoxy Resin Indoor High Voltage Current Transformer



The majority of products are single-phase, because voltage transformer capacity, small body accumulation, the inner and outer insulation between the three-phase high-pressure casing is difficult to meet, so only 3-15kV products sometimes adopt three-phase structure.

Transform rationing by voltage Electromagnetic voltage transformer: According to electromagnetic induction principle, the transformation voltage is similar to the basic structure and Transformer.The capacitive voltage Transformer is composed of capacitive voltage divider, compensation reactor, intermediate Transformer, damper and carrier protection gap, etc.. Photoelectric voltage transformer: Through the principle of photoelectric transformation to realize voltage transformation, is still under development.


Division according to use conditions . In-house voltage transformer: installed in indoor distribution equipment, generally used at and below voltage level;

Home external voltage transformer: installed in the outdoor distribution device, mostly used and above voltage level. According to the ground running state of primary winding
The voltage Transformer of primary winding grounding: the end of the primary winding of the single phase voltage Transformer or the neutral point of the primary winding of the three phase voltage Transformer is directly grounded. The UnGrounded voltage Transformer of primary winding: Both ends of primary winding of single phase voltage transformer are insulated to the ground. All parts of the primary winding of the three-phase voltage transformer, including the terminal, are insulated to the ground and the insulation level is consistent with the rated insulation level.


Divide by Magnetic Route Structure

Single-stage voltage transformer: primary winding and secondary winding(as required, multiple secondary windings can be set up on an iron core, the iron core is ground potential. In our country, the single-stage mode is used at and below the voltage level.
