Abstract

The invention relates to a gas intelligent compensation device of a sulfur hexafluoride breaker. The breaker comprises at least one breaker body. The compensation device comprises a gas storage tank and a controller, a gas pumping in and out system is arranged inside the gas storage tank, the gas storage tank is connected with the breaker body through a guide pipe, and the controller and the gas storage tank are electrically connected with the pumping in and out system used for controlling the inner portion of the gas storage tank. The compensation device guarantees the fact that the problems of low-temperature alarming and locking cannot exist in operating equipment. Meanwhile, the device has the breaker body air pressure field display and background monitor function, the pressure intelligent adjusting functions of body micro-leaking air supply and high-temperature automatic air leakage, the SF6 gas leakage reminding function and other practical functions.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an intelligent gas compensation device for a sulfur hexafluoride circuit breaker. Background technique [0002] Sulfur hexafluoride (SF 6 ) is a colorless, odorless, stable chemical substance that is gaseous at normal temperature and pressure. Because of its very good insulation and arc extinguishing capabilities, it is widely used in power equipment as an insulating medium and arc extinguishing medium . Current Grid SF 6 The circuit breaker has fully replaced the oil circuit breaker, 35kV and above voltage level, SF 6 The proportion of circuit breakers has reached over 98%. [0003] But SF 6 It is a macromolecular gas with a high liquefaction point. In the alpine region, when the ambient temperature drops to -23°C, SF 6 Liquefaction will occur, resulting in a decrease in density, and at the same time, the capacity of the interrupter, that is, the breaking capacity of th...
