The invention discloses an inspection device used for production of a high voltage vacuum circuit breaker, comprising a shell, wherein a plurality of insulated sleeves are sequentially arranged at thetop of the shell from left to right in sequence, a wiring terminal is arranged at the top end of each insulated sleeve, a breaking-closing operation handle is movably connected to the right side of the front part of the shell, an insulated handle is fixedly connected to the top end of the breaking-closing operation handle, an insulated handle sleeve is sleeved on the left side of the insulated handle, and an insulated pressure lever is fixedly connected to the center of the bottom of the insulated handle sleeve. According to the invention, by the match of the insulated handle sleeve, the insulated pressure lever, a fixed rack, a sliding sleeve, a fixed transverse plate, a bearing seat, a movable contact, a fixed seat, a static contact, a pressure sensor, a junction box, a wire and a control panel, pressure values in high voltage vacuum circuit breaker breaking and closing can be accurately measured, and therefore the detection effect of the detection device is improved, the problem ofpoor detection effect of conventional detection devices is solved, and the percent of pass of the high voltage vacuum circuit breaker can be increased.
