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.
