Problems solved by technology

[0005]In order to solve the above-mentioned existing high-voltage isolating switch when the static contact plate and the moving contact plate are merged, generally arc operation or horizontal operation is performed, and the arc is performed at a high place Difficult operation during operation or horizontal operation, which is not conducive to merging. At the same time, it is easy to decouple during long-term use, which is not conducive to the stable use of high-voltage isolating switches. In addition, the technical problem that high-voltage isolating switches are inconvenient to open during use. The present invention provides a A kind of high-voltage isolating switch with anti-off function and method

Abstract

The invention provides a high-voltage isolation switch with an anti-falling function and a method, and relates to the technical field of high-voltage electrics. The technical problem that the static contact plate and the movable contact plate of the high-voltage isolation switch are not easy to combine when needing to be combined is solved. According to the technical scheme, the high-voltage isolating switch comprises a base, the base is provided with a linear manual operation structure, the base is provided with an anti-falling structure, the anti-falling structure is connected with the linear manual operation structure, the linear manual operation structure is provided with a reset structure, the reset structure is connected with the base, and the linear manual operation structure is provided with a high-voltage isolating switch assembly. The operation method comprises the following steps that firstly, the base is installed, the square frame is arranged on the outer side of the connecting rod in a sleeving mode, the manual driving rod is pulled downwards, and the manual driving rod drives the connecting rod to move downwards through the square frame; vertical operation is carried out during merging, actual operation is facilitated, the operation difficulty is reduced, and merging is facilitated.

Description

technical field [0001] The invention relates to the field of high-voltage electric technology, in particular to a high-voltage isolating switch with an anti-off function and a method. Background technique [0002] The high-voltage isolating switch is a commonly used electrical appliance that plays an isolation role in the circuit, and the high-voltage isolating switch is one of the isolating switches. Existing high-voltage isolating switches generally include a moving-end insulating post and a static-end insulating post fixedly connected to the base. A group of isolating contacts arranged at intervals are rotatably mounted on the corresponding mounting bases, and the two ends of the isolating contacts arranged at intervals are detachably clamped to the static contact plate and the moving contact plate respectively. [0003] The static contact plate and the moving contact plate of the high-voltage isolation switch are generally operated in an arc or laterally when they are c...
