Problems solved by technology

[0004] The purpose of the present invention is to at least solve the problem that the cabinet body of the existing protection device is fixed on the ground. The line wiring in the cabinet body is easily affected by the vibration and external force impact at the bottom of the cabinet body, causing the line connection contact port to become loose, so that the protection device will not be able to operate. To solve the technical problems of normal operation, provide a low residual voltage protection device for busbars used in power transmission and transformation systems

Abstract

The invention discloses a busbar low residual voltage protection device used in a power transmission and transformation system, and relates to the technical field of circuit protection devices. A first support plate and a second support plate are fixedly connected, a guide rail is fixedly connected to the mounting plate, and a first slider and a second slider that slide along the axis of the guide rail are slidably connected to the guide rail. A first baffle and a second baffle are fixedly connected, the first baffle is located outside the first slider, a first spring is arranged between the first slider and the first baffle, the second baffle is A second spring is arranged between the sliding block and the second baffle plate; a third spring is arranged on the outer sides of the first baffle plate and the second baffle plate. The present invention buffers vibration and impact, so as to dampen the cabinet body, keep the circuit connection in the cabinet reliable, and improve the stable operation of the device.

Description

Technical field: [0001] The invention relates to the technical field of power transmission and transformation protection devices, in particular to a busbar low residual voltage protection device for power transmission and transformation systems. Background technique: [0002] In the power transmission and transformation system, the phenomenon of overvoltage is very common. With the rapid development of the power industry, the miniaturization of switchgear design, and the large-scale application of power cables have put forward new requirements for insulation coordination and overvoltage protection. The expansion of the system and the use of a large number of vacuum circuit breakers have made the frequency of overvoltage gradually mentioned above. If there is no preventive measure, there may be an overvoltage shock at any time, which will clamp the insulation of the system electrical equipment and cause the system electrical equipment to have an insulation shock. wear fault. ...
