GIS defects simulation device simulate various discharge phenomena inside GIS, suitable for experimental research and instrument assessment of GIS partial discharge live detection.
II. Features
1. Good authenticity: It is designed according to the physical GIS, and the various partial discharge faults inside the GIS are truly simulated. 2. Good integrity: high-voltage equipment such as step-up transformers and coupling capacitors are built into the GIS. 3. Fault simulation: It can simulate GIS tip, suspension, air gap, particle, creeping and other discharge types, and multiple discharges can be combined. 4. Controllable discharge: The type of discharge can be selected arbitrarily to control the initial voltage, extinguishing voltage and discharge intensity of each discharge signal. 5. Diversified detection: It can provide a test platform for pulse current, UHF, ultrasonic, high frequency, SF6 gas analysis and other technical detection. 6. Metering transmission: Built-in pulse current method related coupling and calibration unit, which can be detected simultaneously. 7. Good stability: Each discharge module can be used repeatedly, and the discharge characteristics are stable. 8. Convenient operation: the occurrence and disappearance of various faults can be directly controlled outside the device. 9. Diversification of basins: The basin insulators are equipped with various types such as fully shielded, bare basin, and pouring port. 10. Visualization: Built-in infrared video probe, convenient to observe the internal state and capture discharge video. 11. Built-in sensor: built-in ultra-high frequency sensor, which is convenient for comparison with the tested instrument.
