State grid corporation (changzhou) electrical equipment testing center

Changzhou electrical equipment inspection center testing hall

Two units of 6500MVA short-circuit generators and 220kV power grid are used as the testpower supply of the project, to meet the full test capacity of switchgear 1200kV and below grade, short-circuit test of power transformer 500kV and below grade, etc. Power transmission and transformation equipment that can be tested mainly include: high voltage ACcircuit breaker, highvoltage AC metal-enclosed switchgear, high voltage isolatingswitch, grounding switch, high voltage AC switchgear, highvoltage load switch, contactor, current-limiting fuse, fuse combination electric appliance, box-type substation,transformers, etc.

Main test capability as below:

1. Composite test:

2. Medium voltage direct test

3. Direct HV test

4. Load test

5. Short-circuit test of transformer

6. Thermal stability tes
