Description

Double tongue tension multi-directional grounding clamp

technical field

The utility model relates to a grounding wire clamp, in particular to a double-tongue tensioning multi-directional grounding wire clamp suitable for high-voltage electric equipment power outage maintenance.

Background technique

Since the 10kV busbar is nearly 2.5 meters above the ground and is basically installed in a horizontal direction, if the grounding clamp with double tongue tension before modification is used, the operator will not be able to lift the insulating rod to a horizontal position, let alone The ground wire is installed.

Utility model content

The technical problem to be solved by the utility model is to provide a double-tongue tightening type multi-directional grounding wire clamp, which can ensure that the grounding wire is in good contact with the maintenance equipment, and the installation is firm and reliable, preventing the equipment from reversely transmitting power or nearby induction currents. Threat to maintenance personnel's life.

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

The double-tongue tensioning type multi-directional grounding clamp includes an inverted U-shaped clamp main body. The fixed conductor spring clip is arranged on the clamp main body. One end of the clamp main body is sequentially provided with Insulation pole vertical installation device, multi-strand annealed copper grounding wire nostril and insulation pole horizontal installation device.

The advantages and effects of the utility model are:

The utility model double-tongue tensioning multi-directional grounding clamp includes an inverted U-shaped clamp main body, on which a fixed conductor spring clip is arranged, and one end of the clamp main body is sequentially arranged from bottom to top It is provided with a vertical installation device for insulating rods, a nostril for installing multi-strand annealed copper grounding wires and a horizontal installation device for insulating rods. In this way, one person can easily complete the work of installing the ground wire, reducing the power outage time. The grounding clamp is suitable for the grounding of different substation busbars or steel-cored aluminum stranded wires, which is convenient for the operation team to operate multiple substations. Easy to operate, firm and reliable to install, suitable for grounding of bus bars in different directions such as horizontal and vertical angles, steel-reinforced aluminum conductors, etc., to ensure safe grounding within the operating range of power failure equipment, and to maximize the effective contact area of the grounding wire clamp. It meets the requirements of the short-circuit current at the installation site, prevents the reverse power transmission of the line, and ensures the personal safety of the operators.
