Load shifting device and vacuum arc-extinguishing chamber aging device using load shifting device

Abstract

The invention discloses a load shifting device and a vacuum arc-extinguishing chamber aging device using the load shifting device. A load shifting port is formed in the wall of an aging lead room; the load shifting device which consists of a fixed seat, a support seat and a bearing unit is assembled in the load shifting port; a shifting device which is used for shifting the bearing unit with an arc-extinguishing chambers to be detected between an aging platform and the support seat is assembled in the aging lead room. During the use, the arc-extinguishing chambers to be detected shifts indoors and the detected arc-extinguishing chambers shift outdoors through the rotation of the support seat in the load shifting device on the fixed seat; after the arc-extinguishing chambers to be detected shift indoors, the load shifting port of the aging lead room is blocked by the support seat to prevent the harmful rays generated in the aging process from escaping, so that the automatic loading of the arc-extinguishing chamber aging operation is realized when the radiation resistance in the aging process is ensured and then the arc-extinguishing chamber aging efficiency is accelerated.

Description

technical field [0001] The invention relates to a transfer device and a vacuum interrupter aging device using the transfer device. Background technique [0002] At present, the voltage aging in the process of vacuum interrupter refers to the way of applying high voltage to the interrupter to cause strong spark discharge between the internal contacts and between the contacts and the shielding cover. With the help of such spark discharge to eliminate high beta emission points on internal parts. However, there are two problems in the voltage burn-in devices currently used by arc extinguishing chamber manufacturers: first, the adjustment of the burn-in voltage in the burn-in process needs to be determined by the operator according to the observed spark discharge phenomenon, which is affected by human factors. The interference is large, and the quality consistency is difficult to guarantee; second, because a large amount of X-rays harmful to the human body will be generated duri...

However, there are two problems in the voltage burn-in devices currently used by arc extinguishing chamber manufacturers: first, the adjustment of the burn-in voltage in the burn-in process needs to be determined by the operator according to the observed spark discharge phenomenon, which is affected by human factors. The interference is large, and the quality consistency is difficult to guarantee; second, because a large amount of X-rays harmful to the human body will be generated during the high-pressure aging process, the aging device must be shielded by a lead room during the pressurized aging process, that is, the operator needs to wait After the burn-in is completed, you can enter the interior of the lead room to unload the burn-in interrupter and reload it. This operation method is labor-intensive, and the waiting time for the burn-in device is too long and the utilization efficiency is insufficient.
