Electric power overhaul isolation device for turntable groove wire pipe shearing of high-voltage line load

Abstract

The invention discloses an electric power overhaul isolation device for turntable groove wire pipe shearing of a high-voltage line load. The device structurally comprises a rotating holding handle, arotating tube post, a wire clamping lead pin plate, a base casing, a relay groove seat, a shaft disc transfer device and a digital roller groove, wherein the effect of using the wire clamping lead pinplate to be matched with the shaft disc transfer device is achieved; a wire pipe hemispherical cover and a jacking and clamping groove truss are communicated to form an inner path for conduction by hinging a high voltage wire to the wire clamping lead pin plate; at the moment, overhaul personnel work and rotate a gear shaft post to link a laterality jacking and pushing frame to jack and press thejacking and clamping groove truss, so that the effects that one side of the single-side deflection is in a broken circuit state, and the other side is in a conducted state are achieved; the reeling operation of forming an arc groove by an arc groove disc is also used; during the rotation, a hemispherical square sheet cover is jacked and supported by a groove pad to be put onto the disc body to realize sliding moving; copper wire bur is protected by the wire end hemispherical cover; the approaching to the lead pin to realize the butt joint circuit conduction is convenient; the smooth on-off switching operation of an isolation switch is effectively promoted; the inside loss condition due to wire pipe resistance is reduced; the safety of the overhaul personnel is ensured.

Description

technical field [0001] The invention relates to an electric power maintenance and isolation device for shearing of a turntable slot line pipe loaded by a high-voltage line, and belongs to the field of electric power maintenance and isolation equipment. Background technique [0002] The overload of high-voltage lines is often caused by instantaneous current or excessive voltage. At this time, the load isolating switch is to block the overload of electricity, provide the maintenance staff with safe space for operation and maintenance, and ensure the safety of high-voltage lines. The current technology is common The disadvantages to be optimized are: [0003] The wall of the high-voltage line pipe is thick, and the end of the line pipe is already in a hinged state when it is docked with the load isolating switch. During the power maintenance, the pressure brake jams the line pipe, and the power connection will be broken through the partition or flipping the line pipe head, form...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a power maintenance isolation device for the shearing of the turntable slot line pipe of the high-voltage line load, so as to solve the problem of the wall thickness of the high-voltage line pipe. Already in a hinged state, when the wire tube is stuck by the pressure brake during power maintenance, it will break the power connection through the partition or flip the wire tube head, forming a protective operation that the wire tube is not energized during maintenance, but the wire tube will be subject to top pressure. And bending effect, resulting in the distortion of the rubber tube shell and the loss of extension and tearing, resulting in frequent switching operations, scraping off the burr at the end of the thread and accumulating in the auxiliary maintenance instrument, generating a static arc, which is easy to cause a small combustion-supporting spark.
