Description

Socket

Technical Field

The utility model relates to the technical field of sockets, in particular to a socket.

Background

In a medium-voltage distribution network medium-voltage distribution system, a certain distance is generated from a switch cabinet to a user transformer due to various reasons, so that the medium-voltage distribution network medium-voltage distribution system needs to be connected through a high-voltage insulated cable, and a cable tapping box can be arranged in a certain distance in consideration of factors such as convenience in cable laying, overhaul, troubleshooting and the like.

A cable tapping box is a device for tapping, branching, splicing and switching electrical circuits for a cable run, mostly used outdoors. The conventional socket for the tapping, branching, connecting and converting circuits of the cable line is usually designed by adopting an insulating layer epoxy resin, and the structure can generate a capacitance to ground due to the adoption of the epoxy resin in the insulating layer, so that the socket cannot be contacted, and further, discharge is generated in a polluted and wet environment, and the general environmental resistance is poor; and when an accident occurs, interphase breakdown and explosion are easy to occur, high-temperature and high-pressure gas is generated, and serious damage is caused to property and personnel.

Disclosure of utility model

The utility model provides a socket for solving the problems of poor environment resistance and unsafe performance of the socket in the prior art.

The technical scheme provided by the utility model is as follows:

A socket, comprising: the socket body, the socket body sets up for epoxy integrated into one piece, the outside cladding of socket body has the metal ground shield layer.

Further, the metal grounding shielding layer is arranged by zinc.

Further, a high-voltage conductor is arranged inside the socket body and is used for connecting a cable.

Further, the socket body is arranged in a tee joint structure, and the high-voltage conductor is arranged in the tee joint structure of the socket body.

Further, the high-voltage conductor is provided with a splicing hole at the outlet of the tee joint structure, and the splicing hole is used for connecting a cable.

Further, the metal grounding shielding layer is coated on the outer layer of the socket body along the three-way structure direction from the middle position of the socket body.

The beneficial effects of the utility model include: after the outer layer of the socket body integrally formed by the epoxy resin is subjected to sand blasting, a layer of metal grounding shielding layer is coated, so that the exposed part of the socket is grounded, when the external environment is severe, the socket is not damaged, and as the shielding layer is arranged on the surface of each interface, the tapping box is free from interphase short-circuit fault, and the damage caused by the fault is greatly reduced.
