gascircuit breakers leak check for pinggao

For example, pure SF6 gas is used in gas insulated switchgears (GIS), gas insulated lines (GIL), and gas circuit breakers (GCB). One of practical solutions of controlling the emission rates of SF6 is to reuse by separation and recovery of SF6 of low concentration from the gases mixtures with nitrogen or air in the electric power industry.

    Sep 17, 2019The leak-rate test (MAC test):This test is based on the Penning Discharge Principle which is named after Frans Michael Penning (1894-1953). Penning showed that when a high voltage is applied to open contacts in a gas and the contact structure is surrounded with a magnetic field, the amount of current flow between the plates is a function of the

    SF6 gas circuit breakers can be enclosed in a pressure vessel, referred to as a dead-tank breaker, or open to the atmosphere, referred to as a livetank circuit breaker. For both breaker types, SF6 gas is used to insulate the surrounding system when the breaker opens to allow for separation of the contacts.

    Because the GIS tank is thick, it is easy to produce false welding. The tank may not leak gas after welding for a short time. However, after long time operation, especially when welding parts are corroded and exposed to the air directly, it will cause gas leakage and pose a threat to the safety of the equipment. Figure 14 gives an example.
