Summary of the invention
The purpose of the utility model is to propose the connecting wire integrated circuit board tool that the V insulator string is changed in a kind of suitable compact 500kV transmission line.
The technical scheme that realizes above-mentioned purpose is: the connecting wire integrated circuit board tool that a kind of compact 500kV circuit V insulator string is changed; Comprise conductor wire end card, cross-arm end card and two groups of retraction assemblies; The two ends of every group of retraction assemblies are articulated in the termination, the same side of conductor wire end card and cross-arm end card respectively; Each parts of jig are on same plane, and integral body is quadrangle; Said conductor wire end card is a symmetrical integrated member, and inboard midline position is fixed with the tray of a clamping conductor wire end gold utensil yoke plate; The outside midline position of said cross-arm end card is fixed with a joint that connects cross-arm end gold utensil yoke plate.
A U-lag that opening is inside is arranged on the said tray, and the width of notch and bottom land shape are suitable with the shape of the thickness of conductor wire end gold utensil yoke plate and middle circular hole respectively.
A U-lag that opening is outside is arranged on the said joint, and the width of notch and cross-arm end gold utensil yoke plate thickness are suitable.
Said retraction assemblies is connected to form by manual leading screw and insulation pull-rod.
When changing the V-type insulator string, the tray clamping of conductor wire end card also is fastened on the middle hole wall of conductor wire end gold utensil yoke plate; The U-lag of cross-arm end card is installed on the cross-arm end gold utensil yoke plate, operates two groups of retraction assemblies then simultaneously, draws conductor wire end card and cross-arm end card in, makes the absent-mindedness of insulator string tension force, can implement the replacing of bunch of insulator.
The utility model jig can make things convenient for and stably be fixedly mounted on the line hardware at V-type insulator string place, and what conductor wire end card and cross-arm end card directly promoted is the line hardware yoke plate, can not injure lead and iron tower cross-arm master material; Volume is little, and is in light weight, is convenient for carrying, and is particularly suitable for the replacing of V insulator string in the compact 500kV transmission line.
