Power-taking device for automatic wiring device of ground wire deicing

Abstract

Disclosed is a power-taking device for an automatic wiring device of ground wire deicing. Currents of transmission leads of iron towers are guided to combination, are guided to an opening-closing conducting device, and then are led to carry out deicing on a ground wire of the iron tower. The power-taking device comprises a power-taking device wire clamp and contact finger structures; an external expansion side is arranged at the side of the power-taking device wire clamp; and the contact finger structures are arranged at the external expansion side of the power-taking wire clamp. A plurality of groups of contact finger structure with springs are designed on the power-taking device; and the currents of the power-taking device are guided to the opening-closing conducting device.

Description

technical field [0001] The invention relates to the field of overhead power transmission line engineering, in particular to an electric pick-up used for an automatic wiring device for melting ice of ground wires in overhead power transmission line engineering. Background technique [0002] Transmission lines under extreme climate conditions, especially those in some alpine mountainous areas in my country, are often covered with ice in winter. The longitudinal unbalanced tension generated by the uneven ice coating on the transmission wires and ground wires will cause the tower to tilt or bend to the side with high tension. When the design capacity is exceeded, the transmission wires and ground wires will break , hardware falling off, etc., will cause the tower to collapse in serious cases. In addition, because the overhead ground wire on the iron tower is not like the transmission wire, it can resist partial freezing through the heat generated by the load current, and its ic...

Problems solved by technology

[0004] The purpose of the present invention is to provide an electrical take-off for the automatic wiring device for melting ice of ground wires, so as to solve the problem that when the opening and closing conductor of the automatic wiring device for melting ice of ground wires is directed towards the electrical take-off and the electrical take-off cannot be firmly engaged with the opening and closing conductor 1. The displacement deviation of the opening and closing conductor causes the opening and closing conductor and the electric take-off to not be accurately engaged, and the rain and snow fall on the electric take-off, which causes the freezing of the engaging place to affect the overcurrent and the heavy self-weight of the engaging place, which causes the electric take-off to be biased to one. side question
