Low-voltage grounding wire clamp for compact electrical structure

Abstract

The invention discloses a low-voltage grounding wire clamp for a compact electrical structure. A first clamp body is arranged on the upper portion of a support, one end of the first clamp body is clamped between the two pieces of the support, a second clamp body is arranged at one end of an arc-shaped or curved connecting rod, the other end of the arc-shaped or curved connecting rod is hinged between the two pieces of the support, a return spring is arranged at the hinged end of the arc-shaped or curved connecting rod, a flat nut is arranged on the lower portion of the support and below the arc-shaped or curved connecting rod, an adjusting bolt is connected in the flat nut in a screwed mode, and a connecting device capable of being connected with an insulation operating bar is arranged on the lower portion of the adjusting bolt. According to the low-voltage grounding wire clamp for the compact electrical structure, the contact mode between the first clamp body and the second clamp body is designed to be a rotary clamping type, and the grounding wire clamp is guaranteed to be in reliable contact with a connected conductor. Meanwhile, due to the fact that the angle of the adjusting bolt is adjustable, the function of being capable of adjusting the direction of the clamp mouth of the grounding wire clamp is achieved so that the grounding wire clamp can be conveniently aligned to a connected busbar.

Description

technical field [0001] The invention relates to a grounding clamp, in particular to a low-voltage grounding clamp for a compact electrical structure. [0002] Background technique [0003] With the strengthening of strong and smart grid construction, the State Grid Corporation gradually promotes the use of miniaturized and compact electrical equipment. In many areas, low-voltage branch boxes, switchgear and other low-voltage complete sets of equipment have compact electrical structures and small spaces. The traditional low-voltage grounding wires have insufficient safety distance from live parts during installation, which may easily cause phase-to-phase short circuits and poor grounding wires. If the space is narrow and cannot be installed, it can only be operated by expanding the power outage range of the equipment. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a me...

In many areas, low-voltage branch boxes, switchgear and other low-voltage complete sets of equipment have compact electrical structures and small spaces. During the installation process of traditional low-voltage grounding wires, there is insufficient safety distance from live parts, which may easily cause phase-to-phase short circuits, poor contact of grounding wires, and even If the space is narrow and cannot be installed, it can only be operated by expanding the power outage range of the equipment
