Abstract

The invention relates to a grounding wire device, in particular to a spiral pressing elastic sheet type grounding wire conductor end wire clamp. The spiral pressing elastic sheet type grounding wire conductor end wire clamp comprises a wire clamp shell, a wire clamp shell lid lidding the wire clamp shell and a screw device which is arranged on the wire clamp shell, and the wire clamp shell comprises a clamping part of a U-shaped structure and a conveying part connected to one side of the U-shaped structure; a first spring assembly is arranged at one side inside the clamping part, and a secondspring assembly is arranged at the other side inside the clamping part; a control device controlling the second spring assembly is arranged at the top of the clamping part, a displacement amplifier compressing the first spring assembly is arranged in the conveying part, and the displacement amplifier is connected with the screw device. The spiral pressing elastic sheet type grounding wire conductor end wire clamp is simple in structure and firmly clamps a conductor; meanwhile, the spiral pressing elastic sheet type grounding wire conductor end wire clamp is convenient to operate and improves the work efficiency.

Description

technical field [0001] The invention relates to a grounding wire device, more specifically, to a spiral compression spring leaf type grounding wire conductor terminal clamp. Background technique [0002] The short-circuit grounding wire is the most common safety device in the substation. By lapping the conductor terminal clamps on the three-phase conductors respectively, the three-phase short-circuit of the power failure equipment is short-circuited through the short-circuit wire, and then a grounding wire is led to the grounding pole, so as to realize The protection of the safety of construction personnel within the scope of protection. [0003] At present, the conductor terminal clamps of the station short-circuit grounding wire are mainly divided into two operation modes: thread fastening and double spring compression. For the spring compression type, the operator can directly overlap the wire clip on the conductor, and the conductor can be compressed by the deformation ...

AI Technical Summary

Problems solved by technology

For the spring compression type, the operator can directly overlap the wire clamp on the conductor, and the conductor can be compressed by the deformation pressure of the double spring by pulling it down, and it can be separated by pushing it up. The connection between the sheet and the conductor is not stable, and the clamp is easy to slip off from the conductor under the condition of large external force interference, and the double spring spring is easy to age; for the threaded fastening type, the rotation of the insulating rod is changed by the thread It is the vertical linear movement of the clip, so as to realize the compression of the wire clamp to the conductor, the reliability is high, and the connection is stable. However, this transformation of the rotary motion of the insulating operating rod into the vertical linear motion of the clip through the helical thread has already Sacrificing speed to ensure clamping force requires the operator to reciprocate many turns

Due to the large opening of the contact clip, a large amount of lost travel is caused

In addition, the electrical equipment is installed at a high place, which leads to a relatively high installation position of the temporary grounding wire. The operating rod of the grounding wire is usually relatively long, and the grounding copper wire is very heavy, requiring a lot of strength to operate smoothly; Personnel need to stand on the insulating ladder and wear insulating gloves, raise their hands and rotate dozens of times, which is time-consuming, labor-intensive, consumes a lot of physical strength, and is easy to lose balance and fall
