Description

Grounding device for cable terminal

Technical Field

The utility model relates to the technical field of power cables, in particular to a grounding device for a cable terminal.

Background

The cable terminal is an important matching product of a cable line, and the reliability of the terminal grounding directly influences the operation quality of the cable terminal.

At present, a common grounding mode of cable terminals of cable accessory factories in China and in China is as follows: the grounding cable is firstly in pressure connection with the double-hole wire outlet terminal, and then the double-hole grounding terminal is connected with the tail pipe grounding row through bolts, so that the grounding of the cable terminal is realized.

Another grounding mode adopted by some domestic manufacturers at present is as follows: firstly, the grounding cable conductor is in pressure connection with the grounding pipe of the tail pipe body, and then a waterproof belt, a heat-shrinking sleeve and the like are wrapped at the pressure connection part, so that the grounding of the cable terminal is realized.

As shown in fig. 2, the prior art provides a first grounding mode of a cable terminal, and the grounding mode installation process of the structure is as follows: the grounding cable conductor is firstly in pressure connection with the double-hole grounding terminal, and then the double-hole grounding terminal is connected with the tail pipe grounding row through bolts, so that the grounding of the cable terminal is realized. The grounding mode of the structure is convenient to install and later overhaul because the grounding cable conductor is firstly pressed and connected with the grounding terminal through bolts and then is fixed and detachable. The hidden trouble brought is that the grounding terminal is directly exposed in the air and is easy to oxidize and corrode, so that the contact resistance of the part is increased, and the grounding reliability of the cable terminal is affected.

As shown in fig. 3, the prior art provides a second grounding mode of the cable terminal, and the grounding mode installation process of the structure is as follows: firstly, the grounding cable conductor is in pressure connection with the grounding pipe of the tail pipe body, and then a waterproof belt, a heat-shrinking sleeve and the like are wrapped at the pressure connection part, so that the grounding of the cable terminal is realized. The grounding mode of the structure has good overall sealing and waterproof effects, and the grounding reliability of the cable terminal can be greatly improved. The problem is that the cable conductor needs to be crimped with the grounding pipe of the tail pipe body before being installed on a product, and the cable conductor is limited by the on-site installation environment and is difficult to operate. Meanwhile, the steel cannot be removed after crimping, and the overhaul of the product after operation is not facilitated.
