Abstract

The utility model provides telescopic hardware for an extra-high voltage direct current support type tubular busbar, which is used for connecting and supporting the tubular busbar, and is characterized in that the telescopic hardware comprises a support clip and a telescopic clip, wherein the support clip and the telescopic clip are independently separately arranged, and the outer surfaces of the support clip and the telescopic clip are arranged to be circular arc surfaces; and with the adoption of the telescopic hardware, the range of adjustable distance of the tubular busbar can be enlarged, the tubular busbar can be axially and radially adjusted, the flow guide and support effects are good, the corrosion resistance can be realized, and corona is difficult to occur.

Description

The extra-high voltage direct-current brace type pipe bus gold utensil that stretches

Technical field

The utility model relates to a kind of electric armour clamp, particularly relates to the flexible gold utensil of a kind of extra-high voltage direct-current brace type pipe bus.

Background technology

At present, the flexible gold utensil of normally used brace type pipe bus in transformer station, the flexing line clamp of its passive fixture and interconnect function is same wire clamp integrated setting, promptly welding lead is used for water conservancy diversion on fixture, and fixture can be done the slip along the pipe bus in the kerve of chassis, its design concept all is by fixture body and fixture cover plate pinch tube bus, the lead that is welded on the fixture body is used for water conservancy diversion, though this brace type pipe bus clip is easy for installation, but the adjustable extent of pipe bus is smaller, can only be along pipe bus axial horizontal adjusting, and the water conservancy diversion effect neither be very good.

Summary of the invention

The purpose of this utility model is that solution pipe bus is little apart from adjustable extent, can only be along the axial horizontal adjusting of pipe bus, the problem that the water conservancy diversion effect is bad.

To achieve these goals, the utility model provides a kind of extra-high voltage direct-current brace type pipe bus gold utensil that stretches, the pipe bus is connected and supports, comprise fixture and flexing line clamp, fixture and flexing line clamp independently divide and are arranged, and the outer surface of fixture and flexing line clamp is arranged to arc surface.

Described fixture comprises base, fixture body, fixture cover plate and securing member, and the fixture body is fixed on the base by securing member, fixture cover plate and fixture body by securing member from grip tube bus radially; Described flexing line clamp comprises wire clip body, wire clamp cover plate, lead and securing member, wire bonds on wire clip body, wire clamp cover plate and wire clip body by securing member from grip tube bus radially.

Described securing member is nut bolt and/or screw.

The aperture surface of described fixture body is provided with support slipper, and the aperture surface of fixture cover plate is provided with rubber column.

The fixture body is provided with lock-screw.

Bottom sides at the fixture body is provided with balancing patch.

Compared with prior art, the utlity model has following advantage:

1, the utility model compact conformation is clear.Support function and Telescopic separately increase pipe bus moving range, makes the pipe bus increase the swing of axis ± 15 °.

2. the utility model scope of application increases.The pipe bus can be two horizontal arrangement, can be arranged vertically for two, also can be that three T types are arranged.

3. the utlity model has obvious energy-saving effect.The fixture design is succinct, provides cost savings, and fixture body, fixture cover plate, flexing line clamp body adopt non magnetic high-strength aluminum alloy material, and the design of the slyness of wire clamp and cover plate, and corona is no longer produced, and energy-saving effect is more arranged.

4. the utlity model has superior decay resistance.Because main body adopts aluminum alloy materials, securing member adopts stainless steel material, makes product more corrosion-resistant.

Embodiment

Describe the preferred embodiment of utility model in detail below in conjunction with accompanying drawing.

Present embodiment such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, present embodiment provides a kind of extra-high voltage direct-current brace type pipe bus gold utensil that stretches, comprise fixture 1 and flexing line clamp 2, fixture 1 is by base 3, fixture body 4, fixture cover plate 6, support slipper 5, rubber column 7, screw 8 and lock-screw 10 are formed, flexing line clamp 2 is by wire clip body, the wire clamp cover plate, lead 11 and screw 8 are formed, screw 8 adopts stainless steel material, base 3, fixture cover plate 6, fixture body 4, wire clip body and wire clamp cover plate adopt aluminum alloy materials to make, and the outer surface of aluminum alloy materials is arranged to arc surface, to reduce the generation of corona; Support slipper 5 adopts in the aperture surface of the movable embedding of round roller fixture body 4, support slipper 5 is provided with two, perhaps also can adopt additive method that sliding support is set, realize the axial displacement of pipe bus 12, fixture and flexing line clamp are independent separately to be arranged on the base 3, with the needs that are connected a plurality of fixtures 1 and flexing line clamp 2 can be set on difference pipe bus 12 respectively according to supporting, realize that horizontal type, vertical-type or the T type of pipe bus 12 connects and support.

Fixture body 4 is horizontally fixed on the base 3 by screw 8, fixture cover plate 6 and fixture body 4 are by the radially grip tube bus 12 of screw 8 from pipe bus 12, perhaps also can carry out fastening as required with nut bolt, the aperture surface of fixture cover plate 6 embeds rubber column 7, rubber column 7 protrudes internal diameter and contacts with pipe bus 12, make pipe bus 12 that the upwards swing at 15 degree angles of footpath can be arranged when being held, realize the precision adjustment when pipe bus 12 connects, also be provided with lock-screw 10 on the fixture body 4, convenient pipe bus 12 and fixture body 4, fixing of fixture cover plate 6, the side of fixture body 4 also is provided with two balancing patches 9, balancing patch 9 is fixed on the side of fixture body 4 bottoms by screw 8, and pipe bus 12 is played auxiliary balance and supporting role; The wire clip body of described flexing line clamp 2 and wire clamp cover plate are managed bus 12 by screw 8 from radially clamping, perhaps also can carry out fastening with nut bolt, wire clip body is welded with lead 11, the other end of lead 11 is welded on the wire clip body of another one pipe bus 12, realize water conservancy diversion, can be provided with manyly according to the needs of water conservancy diversion, can weld a plurality of leads 11 on the wire clip body flexing line clamp 2.
