Abstract
The utility model discloses a kind of replacing insulator under electrified specific purpose tool, comprise cross-arm-end stationary fixture, two leading screws and insulating cord, described cross-arm-end stationary fixture is provided with the fastener fixing with cross-arm, described cross-arm-end stationary fixture respectively connected described two externally threaded one end of leading screw band by the screwed hole that its two ends are provided with, the end of described two leading screw band external screw thread other ends is equipped with perforation, an annulus is installed with in described perforation, described annulus vertically mounts described insulating cord, and the end of described insulating cord is connected with Self-locking hanging hook.Compared with prior art, the utility model can complete the replacing of insulator fast, not only for safer operator, and improves operating efficiency.
Description
Technical field
The utility model belongs to technical field of electric power, is specifically related to a kind of replacing insulator under electrified specific purpose tool.
Background technology
Insulator is a kind of special insulation control, between the conductor being arranged on different potentials or between conductor and current potential component, withstand voltage and mechanical stress effect, plays an important role in overhead transmission line.In overhead transmission line, insulator is between tower and conductor, and insulator has two basic effects, namely support wire and prevent electric current from returning (even if wire and shaft tower insulate).These two effects must be guaranteed.Insulator should not cause various dynamo-electric stress because environment and electric loading condition change and lose efficacy, otherwise insulator would not play work
With, the use of infringement whole piece circuit and service life.In electric power system, usually use and form insulator string by multiple insulator.Insulator string connects tower and conductor by gold utensil.Gold utensil is all kinds of device in connection and combinational electric system, to transmit the metal-ware of machinery, electrical load or certain protective action.Insulator string is primarily of multi-disc porcelain or glass insulator composition.Easily there is deterioration or breakage in porcelain or glass insulator, therefore needs to carry out replacing process to deterioration or damaged insulator in time, is replaced with good insulator in time by deterioration or damaged insulator.Existing substitute mode uses guide chain and insulated tension pole to change to strain wire, but it is heavier to there is equipment in this substitute mode, carry inconvenience, and there is use inconvenience in equipment replacement process, operating efficiency is low, adds the problem of the work load of maintainer.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of replacing insulator under electrified specific purpose tool, and replacing conductor spacer that can be convenient and safe, improves operating efficiency.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of replacing insulator under electrified specific purpose tool, comprise cross-arm-end stationary fixture, two leading screws and multistage insulating cord, described cross-arm-end stationary fixture is provided with the fastener fixing with cross-arm, described cross-arm-end stationary fixture respectively connected described two externally threaded one end of leading screw band by the screwed hole that its two ends are provided with, the end of described two leading screw band external screw thread other ends is equipped with perforation, an annulus is provided with in described perforation, described annulus vertically mounts described insulating cord, the end of described insulating cord is mounted with Self-locking hanging hook.
Further, described fastener comprises two groups of U-bolts, and described U-bolt is fixed together by the connecting hole that is provided with in the middle part of described cross-arm-end stationary fixture and cross-arm.
Described two annulus laterally also mount described insulating cord.
Described insulating cord is made up of glass fibre or epoxy resin.
Described Self-locking hanging hook is made up of insulating material.
When the utility model needs to change insulator, described cross-arm-end stationary fixture is fixed together by fastener and cross-arm, wire is hooked with two Self-locking hanging hooks, the handle of rotational lead screw, leading screw is moved to cross-arm-end, automatic coupling simultaneously is also moved to cross-arm-end with leading screw, and then make automatic coupling hook wire, insulator simultaneously between cross-arm and wire also becomes lax, after insulator string is lax, the insulator needing to change can be taken off, change good insulator, the handle of last rotational lead screw, make leading screw to cross-arm oppositely movement, simultaneously automatic coupling also with leading screw to cross-arm oppositely movement, and then make automatic coupling unclamp wire, insulator string simultaneously between cross-arm and wire is also again stressed, return to original position, finally achieve replacing insulator.
The utility model, by the convenient and swift replacing completing insulator of said process, improves operating efficiency; Stability after the insulating cord that described two annulus laterally mount keeps described two automatic couplings to hook wire; Described Self-locking hanging hook and insulating cord all adopt insulating material to make, and add the fail safe of instrument; Glass fibre or the epoxy resin strength ratio of described insulating cord employing are higher, add the useful life of instrument; The insulating cord that the utility model adopts has feature lightweight, easy to carry.
