Description

Electricity testing grounding ring with protection structure

Technical Field

The utility model relates to the technical field of, especially, relate to an electricity testing grounding ring with protective structure.

Background

In the middle and low voltage line of the present urban distribution network (namely 10 kilovolt and below voltage level), generally adopt the aerial insulated wire to lay, and when examining and repairing the line or equipment, in order to ensure the safety of the examining and repairing personnel, the line needs to be verified after no electricity, the earthing protection wire is hung, which requires that the earthing wire clamp and the electric wire must be reliably contacted when hanging the earthing wire, because the insulativity can not be hung, the electricity testing earthing ring must be adopted, the structure of the existing electricity testing earthing ring is shown in figure 1, which comprises a clamping component 1-1 and an insulating ring 1-2, the middle part of the lower end of the insulating ring 1-2 is provided with a wiring part 1-3 exposed outside for hanging the earthing wire, because the wiring part 1-3 is exposed in the natural environment when not used, impurities such as rain water, dust and the like can be attached to the surface of the wiring part 1-3, which is long, the use effect of the device can be influenced, and certain potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to avoid prior art's weak point, provide an electricity ground ring of testing with protective structure to effectively solve the weak point that exists among the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme: an electricity testing grounding ring with a protective structure comprises a clamping part and an insulating ring body, wherein a wiring part exposed outside is arranged in the middle of the lower end of the insulating ring body, and the protective structure is detachably arranged on the outer side of the wiring part;

the protective structure comprises two protective plates which are symmetrically arranged, a first semi-annular protective sleeve is arranged at the middle part of each protective plate in a matched connection mode, a second semi-annular protective sleeve is arranged at the two ends of each semi-annular protective sleeve in a matched mode, and the upper side and the lower side of each protective plate are connected through connecting pieces.

Furthermore, the connecting piece is a thumb screw, a through hole is formed in one of the guard plates in a matched mode with the thumb screw, and a threaded hole is formed in the other guard plate in a matched mode with the thumb screw.

Further, the end part of the first semi-annular sheath pipe abuts against the end face of the insulating ring body.

Furthermore, the connecting piece is provided with four places, is located the upside both ends of backplate and the downside both ends of backplate respectively.

Further, the guard plate is made of an insulating material.

Further, the connecting piece is made of an insulating material.

The above technical scheme of the utility model following beneficial effect has: the utility model discloses a position at electricity inspection ground ring wiring portion sets up detachable protective structure, when not using, it can play fine guard action to wiring portion, when using, directly lift protective structure off, carry out normal earth connection operation can, very practical.
