Description

One kind changes 220kV common-tower double-return linear insulator maintenance ladders
Technical field
The utility model belongs to power industry and changes insulator maintenance ladder structure, in particular by medial potential working method more Change 220kV common-tower double-return linear insulator maintenance ladder structure technologies.
Background technology
220kV double-circuit line tangent towers wire is typically using vertical arrangement, phase cross-arm and lower phase cross-arm, middle phase cross-arm because in It is 7m with the distance between upper phase cross-arm, insulator and connection gold utensil length are 3.14m, can not meet the direct edge of equipotential personnel Rope ladder enters electric field.At present, it is domestic to change 220kV common-tower double-return linear insulator chain operations, all it is to use insulated ladder, operation Personnel are changed along flat ladder into electric field, many with Work tool needed for such a method, and insulated ladder is heavy, installation difficulty, operation Time is longer, and operating personnel will directly contact highfield, although take safeguard procedures, but personnel are exposed to forceful electric power for a long time Off field, different degrees of meeting gives band operating personnel to bring harm.
The content of the invention
With medial potential working method compared with equipotential charged for replacement 220kV common-tower double-return linear insulators, intermediate potential Operating personnel only needs to one section of 7m or so the device for being made for industry human users, the installation weight about 5kg, vehicle transport side of development Just, no matter and setting road is far and near, only need 1 people to be carried to setting, in-site installation is convenient, and ground only needs to 1 people just Device can be hung ground potential operating personnel on job position on tower, tower to cooperate with medial potential working personnel, easily, very Fast can just install device, and intermediate potential can be carried out more changing jobs from electrical body a certain distance with action bars , personnel without directly contact charging equipment just can complete more to change jobs.Solve and enter electric field safety with conventional equipotential Distance is not enough, more into complex operation, installation difficulty, outfit with flat ladder is rotated, with ground potential working system operating difficulties Problem.
To achieve these goals, the technical scheme that the utility model is used is:
One kind changes 220kV common-tower double-return linear insulator maintenance ladders, including angle steel hanging piece, is connected to angle steel hanging piece lower end Two section series connections upper insulation pull-rod, lower insulation pull-rod, be connected to it is lower insulation pull-rod on insulation tightener, be connected to it is lower absolutely Seat on edge pull-rod and below insulation tightener, is hinged and connected to the hanging ladder of lower insulation pull-rod lower end;Wherein:Angle steel hanging piece It is made up of two fastener A with neck, the rectangular cross arrangements of fastener B, fastener A and upper insulation pull-rod bolt connection, Fastener B ends are provided with movable nut, for connecting fastening tower material;The upper pendant of insulation tightener passes through steel cable and drawn with lower insulation Rod is connected, and the lower pendant of insulation tightener is shaped as S-hook, and bolt hole, the S-hook lower end and seat are provided with its end Chair is connected, the height for adjusting seat;Hook is connected for fork-shaped with the lower end of lower insulation pull-rod on hanging ladder, under hanging ladder lower end Suspension member is used for angle cleat.
The utility model fastener A is fixed with insulation pull-rod, and fastener B is played and tower by controlling bolt to move horizontally The effect of material fastening.
The utility model is connected provided with seat controller with seat, for by controlling insulation tightener to adjust seat Highly.
The beneficial effects of the utility model are that medial potential working personnel only need to one section of 7m or so confession operating personnel behaviour The device of work, installation weight about 5kg, vehicle transport is convenient, no matter and setting road is far and near, only need 1 people to be carried to work Industry point, in-site installation is convenient, and ground, which only needs to 1 people, can just hang device ground potential operating personnel on job position on tower, tower Cooperated with medial potential working personnel, device can just be installed easily, quickly, intermediate potential is certain from electrical body Distance, can be carried out more changing jobs with action bars, personnel without directly contact charging equipment just can complete more to change jobs. Solve and enter electric field safe distance not enough with conventional equipotential, with rotate flat ladder enter complex operation, it is installation difficulty, required Instrument is more, with the problem of ground potential working system operating difficulties.
