Ice-melting pup joint quick working device for jackstay-typed electric transmission line

Abstract

The invention discloses an ice-melting pup joint quick working device for jackstay-typed electric transmission line. The quick working device comprises that two ends of the pup-joint cable are connected respectively with a wire-hanging mechanism, wherein the wire-hanging mechanism comprises a fixed clamp splice with a hook on the upper portion of the wire-hanging mechanism, and a movable clamp splice with the top matching with the wire-hanging mechanism and a movable clamp splice fixed base. The permanent seat of the movable clamp splice is installed on the fixed clamp splice. The movable clamp splice is installed movably inside the fixed seat of the movable clamp splice through an up-down moving mechanism. The pup-joint cable is connected with the lower end of the fixed clamp splice. Two ends of the pup-joint cable are provided with the wire-hanging mechanism achieving the quick connection of the pup-joint cable. The quick working device has the advantages of being simple in structure and easy to operate. The quick working device can adjust the position of the movable clamp splice on the fixed seat of the movable clamp splice according to overhead lines with different diameters so as to be applied to the overhead lines with different diameters. The sharp working device is suitable for the ice-melting operation of the electric transmission line.

Description

technical field [0001] The invention relates to the field of power line equipment fittings, in particular to a pole-type power transmission line ice-melting short-circuit quick operation device. Background technique [0002] Before the present invention was proposed, DC short-circuiting was generally used for ice-melting operations, and workers were required to go to the substation in a power outage to short-circuit the overhead line and the DC power supply with a short-circuit cable. Since the ice-melting operation is carried out at high altitude and the operation requirements are higher, the operation risk is greater; at the same time, since it is necessary to install and disassemble the connection of multiple short-circuit cables and overhead wires when short-circuiting, and one short-circuit The cable needs to be manually tightened with about 6 nuts and tools such as nuts and screwdrivers are required, so the workload is heavy and time-consuming, which makes the staff pr...

Since the ice-melting operation is carried out at high altitude and the operation requirements are higher, the operation risk is greater; at the same time, since it is necessary to install and disassemble the connection of multiple short-circuit cables and overhead wires when short-circuiting, and one short-circuit The cable needs to be manually tightened with about 6 nuts and tools such as nuts and screwdrivers are required, so the workload is heavy and time-consuming, which makes the staff prone to fatigue and increases the power outage time; moreover, due to the work of the operators The environment is mostly cold and slippery, so longer working hours are likely to lead to safety accidents
