Description

The device of charged for replacement V-type insulator string

One, technical field

The utility model relate to a kind of on 330 kilovolts of ultra-high-tension power transmission lines the device of charged for replacement V-type insulator string.

Two, prior art

Ningxia especially in the west area, on 330 kilovolts of ultra-high-tension power transmission lines from Guyuan to big Xifeng, having designed the V-type that adopts at the heavy icing area insulator string connects, because the method that on this ultra-high-tension power transmission line, has adopted the special V-type insulator string of structure to connect, the instrument of used power-on serving replacing insulator string can't be used on this kind transmission line on other ultra-high-tension power transmission lines at present, even take the measure that has a power failure, change also difficulty very.

Three, summary of the invention

The purpose of this utility model provide a kind of have two combine simultaneously use, simple in structure, in light weight and use easy to carry can be on 330 kilovolts of ultra-high-tension power transmission lines the device of charged for replacement V-type insulator string.

The utility model is realized in the following way: a kind of device of charged for replacement V-type insulator string, and it comprises two parts that are not connected mutually, it is respectively jig and bottle supporting hook; Described jig comprises an insulation board, the insulation board two ends are respectively by being removably connected with a card and a main leading screw, perpendicular to main leading screw axially on successively activity card and handle are housed, the described side of going up card links to each other with an end of regulating silk, the other end of adjusting thread links to each other with an insurance card; Described bottle supporting hook is made up of shank and two hooks that are fixed on the shank at least; The described profile of card down is " S " type, and respectively there are microscler deep trouth and following microscler deep trouth on one in the bottom of " S " type greater than top on its end face and the bottom surface; There is hole on the top that is " S " profile with the last microscler deep trouth place of communicating, and its underpart has three to be the holes that isosceles triangle distributes with the following microscler deep trouth place of communicating; Described going up blocked the shape that is the counterclockwise turnback of " L " type, the front of its " one " type has two floors to form a U-shaped draw-in groove, one elongated semi-circular groove is arranged above two floors, its top, " one " type the right has two tailgates to form an elongated slot, two tailgate symmetries a through hole respectively arranged, its " 1 " type bottom have one with the perpendicular long draw-in groove of elongated slot place face, the bottom, side of described " 1 " type is " V " type; Described insurance card is " V " type, and " V " type top forms a square groove by two wing plates, with the top of the perpendicular face of " V " profile slide opening is arranged on wing plate, and U type groove is arranged at the bottom.

Described upward card and following card are to be manufactured by aluminium alloy or titanium alloy material; Described bottle supporting hook is to be manufactured by insulating material.

The utility model has following effect:

1) simple in structure, easy to carry: the device that the utility model provides is combined by two parts that are not connected mutually and uses simultaneously, and it comprises jig and bottle supporting hook; Jig is blocked and is blocked down and form by the going up of two ends flexible connection of insulation board, and bottle supporting is linked up with by shank and linked up with and form, thereby it is relatively simple for structure; When installing without this, because all connections of the detachability of employing activity of each part on the jig, thereby they can be removed, so that carry, when using, again they are installed.

2) be fit to the hotline maintenance that special V-type insulator string is especially adopted in the west area on 330 kilovolts of ultra-high-tension power transmission lines in Ningxia, so not only reduced frequency of power cut, and can guarantee in time to send for the user.

3) in light weight, use easy to operate: because jig provided by the utility model mainly adopts aluminium alloy or titanium alloy to make, the bottle supporting hook adopts dielectric resin material to make, thereby in light weight, easy to carry, has alleviated maintenance electrician's load; During use the following of jig one end fastened on grading ring, the insurance card that goes up card and link to each other with last card on the other end links to each other with supporting leg on the iron tower respectively, to take off the bottle hook simultaneously hangs on insulator string, by adjusting handle and regulating a tension force that changes insulator string and can realize changing insulator string, thereby simple in structure, easy operating.
