In use, the tube type bus post insulator is changed the anchor ear of instrument and the two ends that assembly pulley is installed on respectively pole, then anchor ear is connected to the framework concrete bar top of tubular bus, anchor clamps are connected on the crossbeam of tube type bus framework, then the one by one end with two insulating cords is connected on the tube type bus, the other end is walked around one of assembly pulley wire grip or cucurbit rear and on ground or the truck transom and is linked to each other, another rope then is connected on the insulator, thus its equally behind another in the assembly pulley of the bar pole top group pulley with ground or crossbeam on wire grip or cucurbit link to each other and realize the replacing of insulator.
Described assembly pulley is the assembly pulley of claw type, is set side by side with respectively the pulley more than two groups on two goat's horns.
Adopt the assembly pulley of claw type, can improve the support degree of assembly pulley, the knotting wrapping phenomena occurs in the rope that also can avoid walking around simultaneously on the assembly pulley.
Described anchor clamps comprise the support of two U-shapeds and connect two braces of two U-shaped support corresponding sides, be provided with the slotted hole along the extension of brace length direction that passes for the limit of U-shaped support in the top and the bottom of brace, end at the U-shaped support is provided with screw thread, and two braces can be realized the location of U-shaped support on tubular bus structure crossbeam with nut check after passing respectively the corresponding sides of two U-shaped supports.
In use, U-shaped support is being stuck on the pole of upper-lower position, after then upper lower carriage being passed by the upper and lower surface of truck transom respectively, lock after two braces being connected respectively the corresponding sides of U-shaped support up and down, can realize pole is fixed on the crossbeam of framework by support.
Certain described anchor clamps also can adopt anchor ear or U-shaped lockset etc.
The pin nail that two rows are arranged at the interval, both sides of pole epimere Heterogeneous Permutation.
Climbed to the top of pole along this pin nail by tubular bus structure crossbeam place the interval, both sides of pole epimere Heterogeneous Permutation pin nail convenient working personnel.
Described pole is the pole of adjustable in length.
Being adjusted to of pole length is made of pole the rod member more than two sections, between each section or adopt flange to add connector to connect, or mutually be screwed in together.
The insulating cord that is used for the support tube type bus is the Di Nima high strength cord.
In sum, the utility model following advantage compared to existing technology:
Tube type bus post insulator of the present utility model is changed instrument, utilize the design feature of transformer station's tubular bus framework itself, employing is fixed on the concrete bar of framework as the end of the pole strong point with pole with the anchor ear of joint coupling, and the crossbeam that uses anchor clamps and framework carries out rigidity and fixes, tubular bus is without the strong point when having overcome electric substation's tubular bus post insulator replacing, the difficult problems such as insulator lifting difficulty, can realize that surrounding devices does not have a power failure and change the tubular bus post insulator, reduce substantially power failure range, filled up the tubular bus post insulator and changed technological gap.
