Abstract
The utility model discloses a spare protecting card for charged changing a tension resisting insulator chain, which is composed of an insulating pulling plate, a tower end pulling plate hook hinged with one end of the insulating pulling plate, a second transition plate hinged with the other end of the insulating pulling plate, a first transition plate hinged with the other end of the second transition plate and a conducting line end clamping head hinged with the first transition plate. The spare protecting card for charged changing a tension resisting insulator chain is used for an 110KV tension resisting circuit and is matched with a tightener and a bottle carrying stand to play the spare protecting function. The utility model has the characteristics of portable carrying and flexible and convenient use and can enhance the reliability and the security of the charged operation.
Description
The utility model relates to a kind of electric power system power tool, belongs to the charged for replacement strain insulator string backup protection card of using in a kind of power transmission lines overhauling, the construction production.
At present, in the electric power system live line working, transmission line is changed strain insulator string and is adopted the bottle supporting frame to operate, but because this bottle supporting frame mechanical strength is not enough, can not prevent the generation of the person and equipment breakdown effectively, so the safety assurance deficiency.Now, live line working is more frequent in producing in the maintenance of electric power system, construction, and developing a kind of circuit has become objective requirement with the backup protection instrument of charged for replacement strain insulator string.
The purpose of this utility model provide a kind of in live line working the matching used charged for replacement strain insulator string backup protection card that can prevent the person and equipment breakdown generation effectively.
The purpose of this utility model is achieved in that it is by the insulation arm-tie, with the hinged tower end plate pulling hook of insulation arm-tie one end, form with hinged second rebound of the insulation arm-tie other end, the conductor wire end dop that is hinged with hinged first rebound of the second rebound other end, with first rebound.
The utility model be used for 110KV strain insulator circuit, with tightener and the supporting use of bottle supporting frame, play the backup protection effect, it not only improves the reliability and the fail safe of live line working, guarantees electric power netting safe running, improves power supply reliability, the minimizing electric energy loss.Also have the characteristics light, flexible and convenient to use of carrying simultaneously.
Below in conjunction with drawings and Examples the technical solution of the utility model is elaborated.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of conductor wire end dop among the utility model embodiment.
With reference to Fig. 1,2, the utility model is made up of conductor wire end dop 1, first rebound 2, second rebound 3, insulation arm-tie 4, tower end plate pulling hook 5.Conductor wire end dop 1 is to be made by aluminum alloy material, and conductor wire end dop 1 is a gate slot shape, at gate slot position configuration pin 6; First rebound 2 is slab of being made by aluminum alloy material, pin hole is respectively established at its two ends, and second rebound 3 also is to be made by aluminum alloy material, and its front and back is " I-shaped " shape, above it and below be slab, also establish pin-and-hole at the two ends of second rebound 3; Insulation arm-tie 4 is slab of being made by the insulation material, and pin-and-hole is established at its two ends, not only has high mechanical properties, and satisfies electrical strength again; Tower end plate pulling hook 5 one ends are half " worker " font, and the end is provided with pin-and-hole, and the other end is established drag hook, and slotted eye is established in the position, intermediate portion, disposes thumbscrew in slotted eye.Pin is housed pin-and-hole on first rebound, 2 one ends and conductor wire end dop top is hinged, first rebound, 2 other ends place second rebound, 3 one ends hinged by pin, insulation arm-tie 4 one ends place second rebound, 3 other ends hinged by pin, and insulation arm-tie 4 other ends place among half " worker " font one end of tower end plate pulling hook 5 hinged by pin.When the utility model uses that tower end plate pulling hook 5 hooks are fastening by thumbscrew on the angle steel at iron tower cross-arm end place, the lead at strain clamp place snaps in the gate slot of lead termination, and is tightened by pin.
