Abstract

The invention discloses a device for detecting vacuum degree of a vacuum arc-extinguishing chamber. In the detection device, a magnetic control coil is used in the periphery of the arc-extinguishing chamber to be detected to produce a pulse magnetic field; a bracket is arranged under the arc-extinguishing chamber to be detected to play a role in supporting; a positioning mechanism is used for compacting a pipe body of the arc-extinguishing chamber to be detected on the bracket so as to realize the positioning of the arc-extinguishing chamber to be detected; an drawing mechanism is used for clamping a movable pull rod of the arc-extinguishing chamber to be detected and drawing upwards the movable pull rod to pull a movable contact and a static contact open inside the arc-extinguishing chamber to be detected after the pipe body of the arc-extinguishing chamber to be detected is compacted and positioned by the positioning mechanism; therefore, according to the detection device, through the mutual cooperation of the bracket, the positioning mechanism and the drawing mechanism, the positioning and the drawing distance of the arc-extinguishing chamber to be detected are realized; thus, after the magnetic control coil is powered, the vacuum degree of the vacuum arc-extinguishing chamber is detected. According to the detection device, the vacuum degree of the vacuum arc-extinguishing chamber is detected through the cooperation between all mechanisms and rack bodies, so that the detection efficiency of the vacuum degree of the vacuum arc-extinguishing chamber to be detected is improved.

Description

technical field [0001] The invention relates to a vacuum degree detection device for a vacuum interrupter. Background technique [0002] The vacuum interrupter is the core part of the vacuum circuit breaker. In order to realize the current breaking and arc extinguishing, the pressure in the vacuum interrupter is generally not higher than 5×10-4Pa. The pressure in the interrupter directly determines the medium recovery after breaking Intensity, thus affecting the breaking performance of the vacuum interrupter, when the pressure in the interrupter increases seriously, it will cause its breaking to fail completely. Therefore, it is urgent to measure and record the vacuum degree of the vacuum interrupter in the field of practical application. [0003] At present, the vacuum degree testers on the market are basically measured by the magnetron discharge method, that is, the two contacts of the vacuum interrupter are separated by a certain distance, the electric field pulse high vo...
