A high-voltage electric cabinet grounding protection device

Abstract

The invention relates to the technical field of high-voltage electric cabinets, and specifically discloses a grounding protection device for high-voltage electric cabinets, which includes a protection plate, a cable fixing plate, and a terminal block. The bottom is horizontally provided with a clamping plate, and the cable fixing plate and the terminal block are fixed on the side of the protective plate; the protective plate is provided with a threading groove and a fixing hole, the cable fixing plate is set under the threading groove, and the terminal block is set on the Below the cable fixing plate; the cable fixing plate and the terminal block are arranged on the same side of the protection plate, and the clamping plate is arranged on the other side; the threading groove is a through groove, and a threading hole is arranged on the cable fixing plate. A terminal block is provided on the upper side of the terminal block, and a grounding bus bar is provided on the lower side of the terminal block; the protective structure provided by the present invention can fix the wires and cables of different components in high voltage electricity, and connect them with the grounding wire uniformly, which is convenient Use, high safety; the overall structure of the device is simple, easy 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
