Abstract

The invention discloses a device for removing oxide on a double-pole switch. The device for removing the oxide on the double-pole switch comprises a sealing cover made of insulating materials, wherein the sealing cover is provided with an opening. A through hole is formed in the sealing cover, one end of the through hole is connected with a conduit, one end of the conduit is connected with a dust collector, and a transfer bar is placed on the sealing cover. A dull polish ball is placed at one end of the transfer bar, and a motor for rotating the transfer bar is arranged at the other end of the transfer bar. According to the double-pole switch, a movable contact cutter can be manually grinded, air in the double-pole switch is extracted, and the surface of the movable contact cutter is prevented from being oxidized.

Description

technical field [0001] The invention relates to an oxide removal device for a double-pole switch. Background technique [0002] A double-pole switch is a switching device with blade-shaped contacts. It is mainly used for isolating power supply in the circuit, or for infrequently connecting and breaking loads below the rated current. When the knife switch is in the off position, it can be clearly observed, which can ensure the safety of circuit maintenance personnel. [0003] The double-pole switch mainly consists of an insulating base plate, a moving contact blade, a static contact seat, an arc extinguishing device and an operating mechanism. The moving contact knife realizes the on-off of the circuit by closing and disconnecting the static contact on the static contact seat. [0004] Among them, the moving contact knife includes two plates, and the two plates are roughly perpendicular to each other. When passing through, one of the plates is closed with the static contac...
