Problems solved by technology

[0002] In the power industry, when a branch line is powered off for maintenance, the ground wire is hung on the ground ring. If there is a mistake in closing the switch and sending power, the switch cannot be closed because the wire is already in the ground state, so as to ensure the personal safety of the maintenance personnel. The existing grounding ring must be connected after stripping off the cable insulation. The disadvantages are: the insulation protection of the wire is damaged, the conductor part is exposed to atmospheric conditions, and the service life is reduced due to corrosion, and the stripping process is time-consuming and laborious.

Embodiment Construction

[0010] See Figure 1-3. The specific structure is as follows: the lower part of the main body of the grounding ring is the connecting ring 3, and the upper part of the main body of the grounding ring is the main connecting body 1. The main connecting body 1 can be connected to the clip 5 through the connecting bolts. It is hemispherical, and the two are combined to form a sphere. An inner arc surface in contact with the wire is provided on the connecting body 1 and the clamping member 5, and the clip 4 is arranged on the inner arc surface of the two parts.

[0011] When in use, the cable or wire with insulation is placed between the main connecting body 1 and the clamping member 5, then the connecting bolt is tightened, and the clamping thorn 4 pierces the insulation layer of the cable-type wire to reach the conductor to form a conductive loop.

Abstract

This invention relates to one insulation puncture earth ring, which comprises earth ring body and is characterized by the following: earth ring body down part is of connection ring with top part as main connection part connected with clamper through connection bolt; the main connection part and wire inner arc are set with puncture. The invention has the following advantages: without peeling off cable insulation puncture method with easy installation and reliable connection without destroying cable or wire insulation protection layer.

Description

technical field [0001] The invention belongs to a grounding device for power cable or wire maintenance, in particular to an insulation piercing grounding ring. Background technique [0002] In the power industry, when a branch line is powered off for maintenance, the ground wire is hung on the ground ring. If there is a mistake in closing the switch and sending power, the switch cannot be closed because the wire is already in the ground state, so as to ensure the personal safety of the maintenance personnel. In the existing grounding ring installation, the cable insulation must be stripped before connection. The disadvantages are: the insulation protection of the wire is damaged, the conductor part is exposed to atmospheric conditions, and the service life is reduced due to corrosion, and the stripping process is time-consuming and laborious. Contents of the invention [0003] The object of the present invention is to provide an insulation piercing grounding ring, which is...
