Problems solved by technology

When the grounding switch is in the process of opening, due to the influence of weight acceleration, the opening speed is relatively fast. If the speed of the support pad suddenly drops to zero when the opening is in place, if there is no buffer or the buffer is not enough, it will cause the grounding opening to rebound, affecting Electrical distance and grounding switch mechanical structure

Abstract

The invention relates to a grounding switch switch-off buffering device comprising a mounting base and a buffering portion, wherein the buffering portion is an assembled multi-stage buffer body. The multi-stage buffer body includes at least two horizontal buffer portions and a vertical buffer portion. The horizontal buffer portions are successively mounted on the vertical buffer portion from top to bottom, and are a rubber buffer structures. The vertical buffer portion is a spring buffer structure. The grounding switch switch-off buffering device uses the assembled structure, and can reduce and increase the assemblies according to actual needs in order to form products with different buffering requirements. The buffering portion of the present invention is the multi-stage buffer body, thatis, a combination of a rubber cushion buffer and a spring buffer. The rubber cushion can reduce the metal bump between the contact portion of the buffering device and the grounding knife switch of agrounding switch. The switch-off inertia of the grounding switch can be effectively buffered by compressing the spring buffer. The multi-stage buffer body is configured to reduce the switch-off inertia of the grounding switch, avoids the mechanical vibration caused by the switch-off inertia, and enhances the switch-on / switch-off stability and reliability of the grounding switch in operation.

Description

technical field [0001] The invention relates to the field of high-voltage equipment, in particular to an opening and buffering device suitable for high-voltage AC and DC grounding switches. Background technique [0002] The traditional grounding switch is generally not provided with a buffer device or only supported by a rubber pad. When the grounding switch is in the process of opening, due to the influence of weight acceleration, the opening speed is relatively fast. If the speed of the support pad suddenly drops to zero when the opening is in place, if there is no buffer or the buffer is not enough, it will cause the grounding opening to rebound, affecting Electrical distance and grounding switch mechanical structure. [0003] With the continuous and rapid development of my country's economy, power consumption has maintained a high-speed growth. In order to meet the future development of the national economy, the construction of ultra-high voltage and ultra-high voltage ...
