CN202153556U - C-shaped plain end screw type ground clamp - Google Patents

Abstract

A C-shaped plain end screw type ground clamp is composed of a fixed press plate, a sliding press block and a fixed revolving screw pedestal. The fixed press plate is fixedly connected with the fixed revolving screw pedestal through a press plate pedestal connecting rod to integrally form a C shape. The front end of the fixed press plate is provided with an anti-sliding block, a slideway is arranged inside the press plate pedestal connecting rod, one end of a revolving screw passes through the fixed revolving screw pedestal (3) to be connected with the sliding press block which is arranged on the slideway, the other end of the revolving screw is provided with a position for arranging an insulation rod, and the press plate pedestal connecting rod is provided with a grounding wire nostril. In the C-shaped plain end screw type ground clamp, as an anti-sliding stop is added on the front of the upper end of the clamp, the work of installing a grounding wire can be completed easily by one people, and the power failure time is shortened. The operation is convenient, the installing is firm and reliable, the safety ground of power failure equipment can be ensured within the working scope, and the effective contact area of the ground clamp is realized to the largest extent.

Description

C-type flat spiral grounding clamp

technical field

The utility model relates to a grounding wire clip, in particular to a C-shaped flat-mouth spiral type grounding wire clip used when high-voltage electrical equipment is powered off for maintenance.

Background technique

Since the 10kV bus bar is nearly 2.5 meters above the ground and is basically installed horizontally, if the unmodified C-shaped flat-mouth spiral grounding wire clamp is used, since the upper end of the grounding wire clamp has no anti-slip stopper, when the operator rotates When the insulating rod is fastened, it often deviates from an angle of 90 degrees, or even falls off. Another person must hold the insulating rod on the upper part and press the upper end of the grounding wire clamp. It can be installed with tacit cooperation, but it still cannot achieve the purpose of complete contact. The effective contact area can only reach 60%.

Utility model content

The technical problem to be solved by the utility model is to provide a C-shaped flat spiral ground wire clip, which can ensure that the ground wire is in good contact with the maintenance equipment, the installation is firm and reliable, and prevents the equipment from reverse power transmission or the threat of nearby induced electricity. maintenance personnel life.

In order to solve the problems existing in the prior art, the technical solution adopted by the utility model is:

The C-type flat-mouth spiral grounding clamp is characterized in that it includes a fixed pressure plate, a sliding pressure block, a fixed rotating screw base, a rotating screw, a connecting rod for the pressure plate base, and an anti-slip block. The fixed pressure plate and the fixed rotation screw base pass through the pressure plate The connecting rods of the base are fixedly connected together to form a C-shape as a whole. The front end of the fixed platen is provided with a non-sliding block, and the inner side of the connecting rod of the platen base is provided with a slideway. The sliding pressure block on the road is connected, the other end of the rotating screw is provided with the installation position of the insulating rod, and the connecting rod of the base of the pressing plate is provided with a grounding wire nostril.

The advantages and effects that the utility model has are:

The utility model C-type flat-mouth spiral grounding wire clamp has more anti-slip stoppers because of its upper end, so that one person can easily complete the work of installing the grounding wire, shortening the power failure time. The operation is convenient, the installation is firm and reliable, ensuring safe grounding within the operating range of power failure equipment, and maximizing the effective contact area of the grounding wire clamp.
