Experimental Study on Relationship of SF6 Decomposition Products and Partial Discharge in Gas Insulated Switchgear
and a gas detection system are designed to simulate the fault state of discharge to ground.Subsequently
SF6 decomposed characteristic gas components induced by partial discharge are analyzed quantitatively
where the intensity of partial discharge is monitored with the pulse current method.The results show that:①The characteristic gas components from partial discharge-induced SF6 decomposition are SOF2
SO2
and S2OF10;②The volume fractions of SOF2 and SO2 exhibit positive correlation with duration and intensity of partial discharge;③Adsorbent imposes effect on measurement of SF6 decomposition products.
