Ground potential installation type shunt clamp device and installation method thereof

Abstract

The invention relates to a ground potential mounting type shunt wire clamp device and a mounting method thereof. The shunt wire clamp device comprises two wire clamps and a drainage wire, wherein the two wire clamps are arranged on the left side and the right side; the drainage wire is used for connecting the two wire clamps; the upper end of the left wire clamp is connected with a bracket; the bracket is rightwards connected with a first bolt fixedly; a through hole of which the diameter is greater than that of the first bolt is formed in the upper end of the right wire clamp, and the upper end of the right wire clamp is arranged on the first bolt in a sleeving way; the lower end of the right wire clamp is hinged to a rotary block; a threaded through hole is formed in the rotary block, and a second bolt is arranged on the rotary block in a penetration way; a bayonet is arranged at the lower end of the left wire clamp; a head part capable of clamping the bayonet is arranged at the left end of the second bolt; a locking nut is arranged at the right end of each of the first bolt and the second bolt. The device and the mounting method thereof are capable of realizing ground potential mounting of a shunt wire clamp, high in safety, wide in application range, easy to operate and high in operation efficiency.

Description

Technical field [0001] The invention relates to the technical field of power transmission line construction, in particular to a ground potential installation type shunt clamp device and an installation method thereof. Background technique [0002] Heating caused by loose bolts or line overload is a common defect in line operation. Long-term heating or short-term overheating will cause the equipment life to be reduced or even damaged. The installation of shunt clamps to shunt is the basic method to deal with heating defects, and the effect is high. And the scope of application is wide. [0003] At present, the shunt clamps are made of two aluminum clamps connected by drain wires and fastened by bolts on both sides. The installation of the shunt clamps is done by equipotential operation. The specific method is to install the two ends of the insulated hard ladder separately. At the cross arm of the tower and the conductor side (the hanging point is near the heating point), then the e...

AI Technical Summary

Problems solved by technology

[0004] 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
