A kind of protection device for ground wire melting ice automatic wiring device

Abstract

The invention discloses a technical proposal of a protection device for an automatic wiring device for ground wire melting ice, which is installed on an iron tower to lock and protect an opening and closing conductor driven by a motor separated from an electric taker, and on the opening and closing conductor A locking ring is provided, and the protection device includes a locking mechanism, which is inserted into the locking ring of the opening and closing conductor when the opening and closing conductor is in a separated state, wherein the locking mechanism includes a motor and an electric push rod. When the closing conductor is in the separated state, the electric push rod of the locking mechanism is inserted into the locking ring of the opening and closing conductor. The beneficial effect of the present invention is to ensure that the opening and closing conductor does not fall and cause serious electrical accidents in the case of breakage or serious deformation, and at the same time protect the moving contact of the opening and closing conductor from freezing in rainy and snowy weather, thereby effectively The ground is in contact with the electric taker.

Description

technical field [0001] The invention relates to the field of overhead power transmission line engineering, in particular to a protection device for an automatic wiring device for ground wire melting ice. 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 ice thickness is generally far greater than that of the tra...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a protective device for the ground wire melting automatic wiring device, which solves the problem of major electrical accidents caused by the breakage, falling off or serious deformation of the opening and closing conductors due to their own quality and weight. Rain and snow affect the icing of the opening and closing conductors, causing drainage failure problems
