Product introduction:
HZGTU gas-filled non-partial discharge combined electrical test device is suitable for high-voltage, large-capacity GIS, GIL power equipment insulation withstand voltage test, partial discharge test and accuracy test of GIS transformers. It is a necessary device for GIS substations, GIS, GIL power equipment manufacturers, basin insulators, and insulation structural parts manufacturers to conduct preventive tests and factory tests.
Adding a high-voltage casing interface to the equipment can lead to high-voltage, which can perform various high-voltage tests on traditional high-voltage equipment. II.Basic performance of test equipment:
1.Technical index
Voltage level::100kV,200kV,250kV,300kV,500kV,800kV,1000kV.
Capacity:50-2000kVA
High-voltage generation methods: high-voltage transformer step-up and series resonance (power frequency, variable frequency), all step-up methods are one-stage step-up without cascade step-up.
Input voltage (primary voltage):0.35-10kV
Partial discharge of equipment: 1-3pc under rated voltage (normal environment)
Temperature rise: the temperature rise is not more than 65k (50Hz) after running at rated current for 60 minutes
2.Technical parameters of test system components
GTU high voltage non-partial discharge test transformer
The GTU high-voltage non-partial discharge test transformer is the key to the test system. It is placed in a specially designed SF6 insulating container. The high-voltage side is separated from other circuits by high-voltage disc insulators. All low-voltage terminals are placed in the junction box.
The low voltage side of the transformer is wound with excitation winding and measurement winding (measurement winding is only used for system testing). For large-capacity (500kVA and above) transformer compensation, there is an independent compensation winding to better play the test of low voltage and load. Flexibility to improve the efficiency of compensation.
The transformer tank is equipped with a gas/vacuum quick connector, a pressure monitoring gauge, an over-pressure release valve, and temperature and pressure sensors for remote monitoring of the operation console.
