Environment-friendly gas insulated ring main unit auxiliary grounding switch

Abstract

The invention relates to the technical field of network cabinets, and discloses an environment-friendly gas insulated ring main unit auxiliary grounding switch. The auxiliary grounding switch comprises a triangular switch base and an auxiliary positioning base, a grounding switch base is fixedly installed at the top of the switch base, a straight sliding groove is formed in the surface of the grounding switch base, a sliding connection assembly is arranged on the straight sliding groove, and the surface of the sliding connection assembly is rotationally connected with a vertical transmission pull rod. According to the environment-friendly gas insulation ring main unit auxiliary grounding switch, a longitudinal transmission rod rotates rapidly, the contact support and the auxiliary switch contact rotate rapidly, the auxiliary switch contact makes contact with a fuse in a main unit, a fusible core in the fuse is fused rapidly, the main unit is powered off, and parallel grounding is achieved, so the operation speed and the power-off speed of the device are improved, the safety of the network cabinet is ensured to the greatest extent, the purpose of quick power-off is realized, the safety of operation and maintenance personnel is ensured, and the probability of accidents is reduced.

Description

technical field [0001] The invention relates to the technical field of network cabinets, in particular to an auxiliary grounding switch for an environmentally friendly gas-insulated ring network cabinet. Background technique [0002] At present, with the rapid development of my country's economy, the construction of power grids and the transformation of urban grids are deepening, and the number of electrical equipment is increasing. At the same time, the requirements for reliability and safety of power supply are also getting higher and higher. Therefore, high-voltage switchgear has also increased significantly. Terminal users mostly use pre-installed box-type substations. This product integrates high-voltage ring main unit, transformer, and low-voltage switchgear into an outdoor box, which can be quickly hoisted and used immediately, and is very popular among users. The internal high-voltage ring network cabinet, with the national environmental protection, more and more us...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an auxiliary grounding switch for an environmentally friendly gas-insulated ring network cabinet, which has the advantages of conveniently and quickly connecting the contacts of the auxiliary switch to the fuse, and solves the problem that the grounding switch passes through the power output device inside the network cabinet. During operation, because the transmission is relatively slow, it is easy to make the time for the auxiliary switch contact to be connected to the fuse longer.
