high voltage sf6 gas Pressure gauge Process

2020/6/5In a high voltage circuit breaker like SF6, current interruption is achieved by separating the contacts in a gas medium. The sf6 comprises both fixed and movable contacts enclosed in a gas system at a pressure of around 2.8 kg/cm 2. Whenever a fault arises, the movable contacts separate, and an arc strikes in between them.

High quality CIRCUIT BREAKER gas Test Method

Power Frequency Over Voltage Withstand Test. The power system may experience different temporary power over voltage conditions may be due to sudden cut of load from the system, wrong operation of online tap changer, insufficient shunt compensation in the system, etc.Dielectric test on auxiliary and control circuit. There may be abnormal over voltage condition in the auxiliary and control supply circuits, too. Hence, the auxiliary and control circuits of breakers should also be gone through short duration power frequency voltage withstand test.Measurement of the resistance of main circuit. The resistance of main circuit is measured from DC voltage drop across the circuit. In this test, direct current is injected to the circuit and corresponding voltage drop is measured and from this resistance of the circuit is measured.Tightness Test. This test is carried out on mainly gas insulated switch gear. In this test, leakage rate is measured. This test ensures the desired lifespan of the switchgear.See full list on electrical4uHigh Voltage Gas Insulted Switchgear (GIS) Field Testing According to IEEE C37.122 Switchgear Content switchgearcontent/2019/09/18/1554/high voltage gas...2019/9/181 Mechanical tests: Gas Leakage and Gas Quality (Moisture, Purity, and Density): All gas compartments shall be filled with sulfur hexafluoride gas ( SF6 ) or a required gas mixture to the manufacturer's required rated filling pressure and tested to detect any gas leaks.An initial test is performed to detect any and all gas leaks and ensure compliance with the specified maximum gas leak rate.
