LZX-10Q Casting Resin Indoor High Voltage Fully Enclosed Current
Transformer
Division according to use conditions
1. In-house voltage transformer: installed in indoor distribution
equipment, generally used at and below voltage level;
2. Home external voltage transformer: installed in the outdoor
distribution device, mostly used and above voltage level.
3. 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;
4. 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.
5. 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.
Serial voltage transformer: The primary winding is separated into
several cells with the same number of turns, each with its own
independent iron core, with multiple iron cores, and a secondary
winding with high voltage. This type of structure is commonly used
in our country in voltage grade.
6. Combination Transformer: The transformer combined by voltage
Transformer and current Transformer group is called combination
Transformer.
