High-voltage electric cabinet grounding protection device

Abstract

The invention relates to the technical field of high-voltage electric cabinets, and particularly discloses a high-voltage electric cabinet grounding protection device. The device comprises a protection plate, a cable fixing plate and a wire holder, wherein the whole protection plate is of an L-shaped structure, a clamping plate is transversely arranged at the bottom of the protection plate, and the cable fixing plate and the wire holder are both fixed to the side surface of the protection plate; the protection plate is provided with a threading groove and a fixing hole, the cable fixing plateis arranged below the threading groove, and the wire holder is arranged below the cable fixing plate; the cable fixing plate and the wire holder are arranged on the same side surface of the protectionplate, and the clamping plate is arranged on the other side surface; and the threading groove is a through groove, a threading hole is formed in the cable fixing plate, a connector lug is arranged onthe upper side of the wire holder, and a grounding bus is arranged on the lower side of the wire holder. The protection structure provided by the invention can be used for fixing wires and cables ofdifferent components in high-voltage electricity and is uniformly connected with a grounding wire, so that the protection structure is convenient to use and high in safety; and the device is simple inoverall structure and convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of high-voltage electric cabinets, in particular to a grounding protection device for high-voltage electric cabinets. Background technique [0002] Grounding In order to prevent electric shock or protect the safety of equipment, connect the metal chassis or casing of power and telecommunications equipment to the ground wire; use the earth as the ground wire for the current loop. In the power system, it is called grounding to make a good electrical connection between the neutral point, shell or support of the equipment and the electrical device, and the grounding device with a conductor. The function of grounding is not only to introduce some useless current or noise interference into the earth, but also to protect users from electric shock.

Problems solved by technology

[0003] When the cables in the existing high-voltage cabinets are grounded, because there is no special grounding device, the operation is cumbersome; moreover, there may be more than one grounding busbar, and the wires are intricately arranged during wiring, which is not easy to organize and brings inconvenience to maintenance , at the same time, there are risks, and it is easy to have leakage due to operational errors or other reasons
