Description

Shunt clamps available for ground potential installation

technical field

The utility model relates to the technical field of power transmission line construction, in particular to a shunt clip which can be installed with ground potential.

Background technique

Heat generation caused by loose bolts or line overload is a common defect in line operation. Long-term heat generation or short-term overheating will cause equipment life to be reduced or even damaged, and shunting by installing a shunt clip is the basic method to deal with heat generation defects. The effect is high And it has a wide range of applications.

At present, the shunt clamps are connected by two aluminum clamps with drain wires, and the two sides are fastened by bolts. The installation of the shunt clamps is completed by equipotential operation. The specific method is to install the two ends of the insulated hard ladder separately. On the side of the tower cross arm and the conductor (the hanging point is near the heating point), and then the equipotential workers wear high-voltage shielding clothing and enter the high-voltage electric field on the conductor side through an insulated hard ladder, remove the bolt on one side of the shunt clamp and insert the conductor, and then tighten both sides. Bolt to keep it in place.

Due to the limitations of the existing shunt clamps, the installation of the shunt clamps can only be carried out by using the equipotential operation method, but there are many shortcomings in the use of the equipotential operation method: one is the safety of the equipotential operators. For high-voltage electric field operations, any negligence or inadequate safety measures may cause high-voltage electric shock accidents; the second is the scope of application of equipotential installation shunt clamps. Equipotential operations have strict requirements for safety distances. Especially when the live equipment in the substation is compact, the safety distance specified in the safety regulations cannot be reached, and the equipotential operation cannot be carried out; the third is the cumbersome operation of the equipotential installation of the shunt clamp, and the equipotential operation has many procedures and tools. , There are many auxiliary personnel who are required to cooperate with the equipotential operators, and the operating efficiency is low.

Contents of the invention

The purpose of the utility model is to provide a shunt clamp which can be installed with ground potential. The shunt clamp can be installed with ground potential. It not only has high safety, but also has a wide application range, and is easy to operate and easy to assemble and disassemble.

In order to achieve the above purpose, the technical solution of this utility model is: a shunt clamp that can be installed at ground potential, including two clamps on the left and right sides and a drain wire connecting the two clamps. The upper end of the side clamp is connected with a bracket, and the bracket is fixedly connected to the right with a first bolt, and the upper end of the right clamp is provided with a through hole with a diameter larger than the first bolt, and is sleeved on the first bolt The lower end of the right clamp is hinged with a rotating block, the rotating block is provided with a threaded through hole, and a second bolt is pierced, the lower end of the left clamp is provided with a bayonet, and the left end of the second bolt is provided with a snap-on Hold the head of the bayonet, and the right ends of the first bolt and the second bolt are respectively provided with lock nuts.

Further, the upper end of the left wire clamp is hinged to the bracket through a pin shaft, so that the left wire clamp can swing left and right around the pin shaft.

Further, the bracket is provided with an operating rod connecting portion for connecting the operating rod.

The beneficial effect of the utility model is to provide a shunt clip that can be installed at ground potential, which can be remotely installed at the ground potential by using an operating rod and auxiliary tools, compared with the traditional shunt clip installed in an equipotential manner , not only improves safety, reduces the risk of electric shock accidents for operators, but also expands the scope of application, and is simple to operate, easy to assemble and disassemble, high in operating efficiency, and has strong practicability.
