Abstract

The invention aims at providing a real-time monitoring and charged gas supply device for an SF6 gas in a circuit breaker used for solving the technical problems of real-time monitoring and gas supplyof the gas in the circuit breaker. The device comprises an electric cabinet, the circuit breaker, a monitoring mechanism, a gas supply mechanism and a control system, wherein the circuit breaker is provided with a density detector tube, a gas regulator tube and an arc-suppressing pressure sensor; the gas supply mechanism comprises a gas supply tube, a gas supply tank, a gas supply electric controlvalve and a gas supply pressure sensor; the gas supply tank communicates with the gas regulator tube through the gas supply tube; the gas supply electric control valve is arranged on the gas supply tube; and the control system is electrically connected with the arc-suppressing pressure sensor, a gas density meter, the gas supply electric control valve and the gas supply pressure sensor separately. The real-time monitoring and charged gas supply device has the beneficial effects that the density of the SF6 gas in the circuit breaker can be monitored in real time, and intelligent inflation anddeflation can be implemented.

Description

technical field [0001] The invention relates to the technical field of sulfur hexafluoride circuit breakers, in particular to a circuit breaker SF6 gas real-time monitoring and charged gas supply device. Background technique [0002] The density or pressure of the SF6 gas in the sulfur hexafluoride circuit breaker directly affects the insulation performance and arc extinguishing effect of the circuit breaker. The sulfur hexafluoride circuit breaker is affected by some circumstances, and the internal SF6 gas indicator will be toggled. In order to ensure the safety performance of the circuit breaker, in the prior art, the SF6 gas index of the sulfur hexafluoride circuit breaker is usually checked by means of power failure, but this will have a great impact on the power supply. Contents of the invention [0003] The object of the present invention is to provide a circuit breaker SF6 gas real-time monitoring and charged gas supply device, which is used to solve the technical ...
