Embodiment Construction

[0027] The present invention will be further described below in conjunction with the description of the drawings and specific embodiments.

[0028] Such as Figure 1 to Figure 7 As shown, a cable grounding box includes a box body 1, an internal connection structure 2 located inside the box body 1, and an external connection structure 3 located outside the box body 1, and a double-way connection structure is installed on the box body 1 Insulation sleeve 11.

[0029] The box body 1 is generally made of stainless steel to ensure high mechanical performance and good sealing performance; internal connecting elements are made of materials with excellent electrical conductivity.

[0030] The double-way insulating sleeve 11 is installed on the box body 1 for connecting the inside and outside of the grounding box.

[0031] The internal connection structure 2 uses bolts to directly connect the strip-shaped internal copper bar 21 to the double-pass insulating sleeve 11 to replace the o...

Abstract

The invention provides a cable grounding box which comprises a box body, an internal connection structure located in the box body and an external connection structure located outside the box body, a two-way insulation sleeve is installed on the box body, and the external connection structure is connected with the internal connection structure through the two-way insulation sleeve. The invention further provides an installation method of the cable grounding box. The cable grounding box and the installation method thereof have the beneficial effects of simple and convenient installation, low cost and high sealing performance.

Description

technical field [0001] The invention relates to a grounding box, in particular to a cable grounding box and an installation method thereof. Background technique [0002] The grounding box is a device for grounding the metal sheath to limit the induced voltage and fault voltage on the metal sheath of the power cable, to avoid the formation of circulating current in the sheath. [0003] To install the existing grounding box, first strip the cable, insert the cable into the sealing sleeve to the clamp, tighten the compression screw and loosen the screw on the clamp, then clamp the cable with a throat clamp, and then seal the sealing tube and the sealing tube with a heat shrinkable tube. Where the cables are connected, the port of the heat-shrinkable tube is wrapped and sealed with waterproof tape in a semi-overlapping manner to complete the connection between the cable and the interior. [0004] The existing grounding box has the following defects: [0005] 1. Installation: T...
