In the 110KV GIS (gas-insulated switchgear) test, a variety of electrical equipment is required to ensure its performance and safety. The following are the main electrical equipment and their functions:
High-voltage test transformer
It is used to provide high voltage power supply, perform voltage resistance test and partial discharge test to verify the insulation strength of GIS.
Partial discharge detector
It is used to detect partial discharge in the GIS and evaluate the health status of the insulation system.
Loop resistance tester
Measure the resistance of the conductive loop inside the GIS to ensure good contact and reduce energy loss.
SF6 gas leak detector
Detect the leakage of SF6 gas in the GIS to ensure stable gas insulation performance.
SF6 gas moisture tester
Measure the moisture content of SF6 gas to prevent excessive moisture, resulting in decreased insulation performance.
Circuit breaker characteristic tester
Test the closing time, speed, synchronization, and other parameters of the circuit breaker to ensure its reliable operation.
Insulation resistance tester
Measure the insulation resistance of GIS and evaluate whether its insulation performance meets the requirements.
Ground resistance tester
This section describes how to check the grounding system of the GIS to ensure equipment and personnel safety.
oscilloscope
It is used to record and analyze the voltage and current waveform in the test process and assist fault diagnosis.
Multifunctional relay protection tester
Verify that GIS protection devices (such as overcurrent, differential protection, etc.) operate correctly.
These devices work together to ensure that the 110KV GIS meets design requirements and safety standards before it is put into operation. During the testing process, it is necessary to strictly follow the procedures to ensure the accuracy of data and the reliability of the equipment.
