Abstract
The invention relates to a multifunctional overcurrent clamp capable of being mounted vertically. The multifunctional overcurrent clamp comprises a conductor clamping groove, a T-shaped mounting head and an insulated U-shaped mounting rod; the T-shaped mounting head comprises a locking lead screw and a mounting plate; the locking lead screw is vertically mounted in the middle of the mounting plate; two through grooves are formed in the mounting plate; a bead is arranged in each through hole; a screw hole is formed in the conductor clamping groove; the locking lead screw is connected with the conductor clamping groove by use of the screw hole; the two plugs of the insulating U-shaped mounting rod are inserted into the two through holes. The multifunctional overcurrent clamp is rotated by a worker on a tower to drive the conductor clamping groove to be tightened or untightened; when an overcurrent pulley is mounted on a horizontal live conductor, an arc extinction rope is used for short-circuiting the potential difference of drainage by use of the overcurrent pulley. The clamp can be applied to any towers and any conductors. The clamp is manufactured by use of a high-strength aluminum alloy, and has the characteristics of light weight, high strength, strong current conductivity and convenience for mounting.
Description
Technical field
The present invention relates to 220kV and 66kV hot line maintenance used tool, especially relating to can vertically arranged multi-functional overcurrent fixture.
Background technology
Drainage due to strain tower of transmission line is the installation form of slow arc downwards, need the live wire metal wire short circuit of connecting plate both sides in the work of the charged disconnecting drainage of the circuit of both sides connecting plate, to guarantee that the live wire of both sides in the process before and after connecting plate is opened is on same current potential all the time, there is no the generation of potential difference.The method of conventional transmission lines road charged disconnecting drainage adopts equipotential electrician to enter highfield by the method for metal wire bundling in the downward drainage of slow arc to carry out short circuit, make the live wire of both sides be on same current potential, huge potential safety hazard is all also existed for job safety, handling safety, personal security.
Existing overcurrent fixture has two kinds:
The first is owing to being connected fastening being arranged in the downward drainage of slow arc with insulating bar, insulating bar is non-dismountable, can affect other program of operation.
The overcurrent fixture of the detachable insulating bar of the second is not connected with insulating bar, is to lock after utilizing insulating bar to hang again, but can only hang on the wire of level, and the downward drainage of slow arc is not installed.
Summary of the invention
The technical problem to be solved in the present invention is to provide can vertically arranged multi-functional overcurrent fixture, can independently be arranged on arbitrarily angled live wire.
In order to solve prior art Problems existing, the technical solution used in the present invention is:
Can vertically arranged multi-functional overcurrent fixture, include wire draw-in groove, T-shaped mounting head and the U-shaped mounting rod that insulate, described T-shaped mounting head includes locking screw and mounting panel, locking screw is vertically mounted on the middle part of mounting panel, mounting panel has two through holes, be respectively provided with a collision bead in each through hole, wire draw-in groove is provided with screw, locking screw is connected with wire draw-in groove by screw, and two plugs of the U-shaped mounting rod that insulate are inserted in through hole.
The U-shaped mounting rod of described insulation includes U-shaped fork and insulating bar, and U-shaped fork and insulating bar are linked by butterfly and connect, and the madial wall of U-shaped fork is provided with collision bead groove.
The sidewall of described wire draw-in groove is provided with suspension ring.
The sidewall of described wire draw-in groove is provided with overcurrent pulley.
The advantage that the present invention has and effect are:
The present invention can vertically arranged multi-functional overcurrent fixture owing to including wire draw-in groove, T-shaped mounting head and the U-shaped mounting rod that insulate, wire draw-in groove is provided with screw, locking screw is connected with wire draw-in groove by screw, and two plugs of the U-shaped mounting rod that insulate are inserted in T-shaped mounting head.Wire draw-in groove is used for locking belt electric lead and makes it reliably be connected with wire, the tightness of adjustable wire draw-in groove when locking screw rotates, T-shaped mounting head can increase revolving force distance, be connected with the U-shaped mounting rod of insulation temporarily, can install with the U-shaped mounting rod of insulation at any time and dismantle, with collision bead and collision bead groove increasing friction force, suspension ring are used for being connected with extinguishing arc rope and insulating cord, the U-shaped mounting rod that insulate is inserted in T-shaped mounting head, with collision bead groove and collision bead increasing friction force, on tower, staff is by rotating it with the degree of tightness driving wire draw-in groove, when overcurrent pulley is arranged on the live wire of level, extinguishing arc rope is by the potential difference of its short circuit and drainage.This fixture can any tower, any wire uses.The present invention adopt high-strength aluminum alloy be made, have lightweight, intensity is large, water conservancy diversion is strong, be convenient to installation feature.
Use staff of the present invention that insulating bar can be utilized to install on shaft tower, avoid staff and enter the hazards brought in forceful electric power place, enhance fail safe.The present invention can not be subject to the restriction of turriform, wire angle, greatly improves the scope of operability and improves work completion rate, is the extremely strong tools for live working of a versatility.
