Fast arc-extinguishing drainage wire locking and releasing device

Abstract

The invention relates to a drain wire locking release device with rapid arc suppression. The device comprises an insulation rod, an eccentric shaft and a clamping board, the insulation rod is fixedly connected with the eccentric shaft through a connecting rod, the clamping board is in an L shape, a connecting end of the L-shaped clamping board is arranged on the connecting rod through a rod sleeve, the rod sleeve is connected with the connecting rod in a rotating manner, a work end of the L-shaped clamping board is parallel to the eccentric shaft, and the upper surface of the work end of the clamping board is provided with arc wire grooves. According to the device, wires are arranged in the wire grooves through the setting of the clamping board and the eccentric shaft; when one surface, away from the axis, of the eccentric shaft rotates to the upper surface of the clamping board, the gap between the eccentric shaft and the clamping board is reduced, and rapid locking of the wires can be realized; when one surface, close to the axis, of the eccentric shaft rotates to the upper surface of the clamping board, the gap between the eccentric shaft and the clamping board is increased, the release of the wires can be realized, rapid arc suppression can be realized, the problem of discharge of a drain wire due to lengthening of arc is avoided, and the device is applicable to narrow space.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission and transformation, and in particular relates to a fast arc-extinguishing drain wire locking and releasing device, which is suitable for live maintenance operations of power transmission lines and substations. Background technique [0002] During the operation and maintenance of the 220kV-66kV power system, it is often necessary for the operator to cut off the fault point and use the insulation to cut off the drain wire. In the past, multiple insulating lock bars were used in the process of live disconnection, and 3-4 people Cooperate with fixing the drainage line, connect the consumable rope to the drainage line, arrange the arc suppression measures, and cut the drainage line with insulating wire cutters. Fixing the drainage line requires more manpower and tools, which is not conducive to the operation in the narrow space of the tower, often causing The arc extinguishing time ...
