A ground wire protection device

Abstract

The invention discloses a grounding wire protection device. The grounding wire protection device is composed of a sheath, a conductive ring, a sealing ring and a moisture-proof filler. A release pipe is arranged in the center of the sheath, and its outer wall is uniformly arranged in an annular ring perpendicular to the axial direction of the release pipe. It is raised and integrally formed with the sheath. There are at least two sealing rings with wire holes in the middle, which are evenly distributed inside the sheath from the top of the sheath, and between the two sealing rings and between the sealing ring and the inner wall of the sheath. Set moisture-proof filler, at least 3 conductive rings, which are evenly distributed inside the pay-off pipe. The conductive rings are provided with wiring holes, and a conductive paste layer is provided in the wiring holes. Compared with the traditional grounding wire, the invention improves the corrosion resistance of the grounding wire while improving the conductivity with the earth, effectively prolongs the effective service life of the grounding wire, reduces the number of inspections, and provides great convenience. The grounding wire detection and replacement operation improves the grounding reliability of electrical equipment, reduces the labor intensity of grounding wire detection, maintenance and replacement, and improves the efficiency of line protection operations.

Description

technical field [0001] The invention relates to a ground wire protection device, which belongs to the technical field of electric power protection. Background technique [0002] The grounding wire is used to realize the connection between the electrical system and the earth to form an equipotential, so as to achieve the purpose of electrical protection for the electrical system, operators and flammable and explosive places. It is widely used, but many electrical accidents that occur in reality , The reason is mostly caused by poor grounding caused by environmental corrosion after the grounding wire has been used for a long time. The light ones cause power outages due to tripping or damage to electrical equipment, and even cause electric shocks and fires in severe cases. Major accidents, in order to overcome this problem, when laying wires, it is often practiced to increase the wire diameter ratio of the grounding wire to spray or electroplate an anti-corrosion layer on the o...

[0002] The grounding wire is used to realize the connection between the electrical system and the earth to form an equipotential, so as to achieve the purpose of electrical protection for the electrical system, operators and flammable and explosive places. It is widely used, but many electrical accidents that occur in reality , The reason is mostly caused by poor grounding caused by environmental corrosion after the grounding wire has been used for a long time. The light ones cause power outages due to tripping or damage to electrical equipment, and even cause electric shocks and fires in severe cases. Major accidents, in order to overcome this problem, when laying wires, it is often practiced to increase the wire diameter ratio of the grounding wire to spray or electroplate an anti-corrosion layer on the outer surface of the grounding wire, but this method only delays the grounding. Therefore, it is necessary to regularly inspect and replace the grounding wire. The inspection interval is generally about one year, but in areas with severe corrosion, inspection is almost every month. On the one hand, it increases labor intensity, and on the other hand On the one hand, it also brings great hidden dangers to the safe operation of the power system.
