Description

An easy-to-detach anti-corrosion ground electrode connector

technical field

The utility model belongs to the technical field of lightning protection and live detection in electric power engineering, in particular to a detachable anti-corrosion ground electrode connection device.

Background technique

In the process of transmission line operation and maintenance, it is necessary to measure the grounding resistance of the grounding electrode of the power tower every year. According to the grounding resistance measurement method and technical requirements, the connection with the grounding electrode must be disconnected for accurate detection. At present, in the grounding device of the power line, the grounding electrode and the down conductor are mostly connected by means of bolt fastening or welding. The bolt connection method is very easy to rust, and it leads to insufficient leakage of the grounding device when the equipment is struck by lightning. It is difficult to disassemble and reinstall the rusted bolts during inspection, resulting in a great waste of manpower and material resources. Although the welding method solves the problem of leakage, it needs to be cut every year for inspection, and then welded after the measurement is completed, and the grounding lead will be shortened after cutting every year, and an additional secondary wire has to be welded in the end. The construction is time-consuming and laborious, and the process is rough. , has been far from meeting the requirements of modern power grid construction.

detailed description

Referring to the accompanying drawings, an easy-to-detach anti-corrosion grounding electrode connector is characterized in that: the connector is provided with a wire barrel 1, hollow screws 2 are threaded at both ends of the wire barrel 1, and the inside of the wire barrel 1 is an oil chamber 3 , The hollow screw 2 is provided with a hole 4, and the lower end of the hole 4 is provided with a conical crimping joint 5, and the two ends of the hollow screw 2 are respectively fixed by a gasket 6, a spring pad 7 and a nut 8.

When in use, fill the oil chamber 3 with butter, pass the grounding leads 9 on both sides through the holes 4 in the hollow screw 2, and use the conical crimping head 6 to crimp and fix the ends of the grounding leads 9 so that the grounding leads 9 will not automatically Pull out; relatively rotate the upper and lower two hollow screws 2, so that the upper and lower conical crimping joints 5 are in close contact, and then the hollow screws 2 are fixed by the gasket 6, the spring pad 7 and the nut 8 respectively. The connecting wire cylinder of the utility model is provided with an oil cavity to ensure that the connector is no longer corroded during installation. When performing ground resistance detection, if it is necessary to disconnect the ground wire, unscrew the hollow screws fixing the ground lead at both ends of the wire drum to realize the disconnection of the ground wire, and then tighten the screws at both ends after the detection is completed.
