Clamping device for electrical contact of isolating switch

Abstract

The invention discloses a clamping device for an electrical contact of an isolating switch, comprising: a base, a first clamping part and a second clamping part; the first clamping part comprises: two first telescopic rods, two second Two telescopic rods, two third telescopic rods, rollers, two first rotating shafts, two second rotating shafts and two rollers, the second clamping part includes: two fourth telescopic rods, two fifth Telescoping rod, third hinge, fourth hinge and two clips. The present invention adapts to electrical contacts of different sizes and radians by adjusting the components of the first clamping part and the second clamping part before and during spraying. Adjust the parts of the first clamping part and the second clamping part to move the electrical contacts, adjust the spraying position, angle and distance, and maintain the plane spraying of the electrical contacts, so as to improve the deposition efficiency of spraying, the quality of the deposited layer and the deposition thickness, no need to move the spraying device, greatly reducing the workload, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of isolation switch protection, in particular to a clamping device for an electrical contact of an isolation switch. Background technique [0002] Cold spray technology can be traced back to the mid-1980s. Its principle is that high-temperature and high-pressure gas is accelerated through the Laval nozzle to obtain low-temperature and high-speed airflow. The airflow accelerates solid particles, causing them to hit the substrate at high speed, resulting in plastic deformation to achieve bonding. During this process, solid particles are accelerated to over 300m / s. Compared with other thermal spraying technologies, the biggest advantage of cold spraying is that the process temperature is lower (up to about 1100°C), which can greatly reduce adverse reactions such as particle oxidation and decomposition. Because there is no large amount of heat input, the coating prepared by cold spraying maintains the original ...
