Abstract
The invention discloses a kind of more hanging point combination hardware fittings of large span hanging tubular bus, the combination hardware fitting includes suspension gold utensil, yoke plate, compensation linkage, grading ring, its mounting means is that more than two suspension gold utensils are taken at the both ends of pipe busbar respectively, often yoke plate is used between two hanging points in end, the gold utensils such as pull rod connect, the junction of each yoke plate carries out pressure shielding using grading ring, the yoke plate of outermost end is connected by insulator chain and the pylon of respective side respectively, the installation of large span hanging tubular bus and cost-effective is realized by the mounting means of combination hardware fitting and more hitch points.
Description
Technical field
The present invention relates to power transmission and transformation fields, and in particular to a kind of more hanging point combination hardware fittings of large span hanging tubular bus.
Background technology
Transformer substation tubular busbar is equipped with brace type and suspension type, and the installation of pipe bus hanging formula can greatly reduce pillar
Quantity, anti-gentle breeze vibrations and antiseismic ability are strong, and eliminate the failure that Insulator detection is caused due to pipe mother's amount of deflection
Occur, hanging tubular bus is applied in the installation of transformer substation pipe busbar more and more widely, but traditional suspension type installation is all
It is 2 suspension types, since the spacing of two hanging points is larger, in addition centre, which must increase, draws lower gold utensil, especially 750kv or more
It is super, extra-high voltage power transformation engineering pipe busbar span is increasing, causes pipe busbar amount of deflection larger, not only influence the beauty of substation,
And have an effect on the safe operation of substation.
Invention content
The purpose of the present invention is to provide a kind of novel hanging tubular bus assorted golden tool of more hanging point structures, realization sides
Formula is as follows：
The combination hardware fitting includes four suspension gold utensils being mounted on tube type bus, four connection being connect with suspension gold utensil
Plate, two pull rods and four grading rings.
The yoke plate and Equalized voltage ring construction are various.
The pull rod is compensation linkage, and there are one latch closures respectively at pull rod both ends.
When installation, the both ends of pipe busbar are respectively separated two suspension gold utensils of installation, often hold between two hanging points using yoke plate,
The gold utensils such as pull rod connect, and the junction of each yoke plate carries out pressure shielding using grading ring, edge substring respectively with the connection of outermost end
Plate is connected with pylon.
The beneficial effects of the present invention are：The size of hanging tubular bus installation horizontal span is to determine the amount of deflection of pipe mother
Most critical factor, the length of insulator chain must be increased by changing horizontal span, in this way in the case where meeting electrical insulation properties
The height that pylon must just be increased will certainly increase construction cost in this way, and the present invention is suspended in midair using more hanging points, be drawn by adjustable
Bar adjusts second hanging point at a distance from first hanging point, and the pulling force of insulator chain is extended to second hanging point, is quite shortened
Pipe mother's horizontal span, can greatly reduce the amount of deflection of pipe mother, and do not increase mounting cost, installation is simple, flexible adjustment, side
Just.
Description of the drawings
Fig. 1：Pipe busbar Multi-point hung type installation diagram
Fig. 2：Compensation linkage
Fig. 3：Yoke plate
Fig. 4：Grading ring
In figure：1 is tube type bus；2 be suspension gold utensil；3 be pull rod；4 be grading ring；5 be yoke plate；6 be insulator chain；7
For steel tower.
Specific implementation mode
Fig. 2 is pull rod, and both ends are lead screw, and screw rod one end is latch closure, is hollow steel pole among pull rod, and steel pole both ends are spiral shell
Parent structure, nut just coincide with lead screw, meanwhile, the internal diameter of hollow structure part is more than the outer diameter of lead screw, needs to adjust
When rod length, just steel pole or lead screw are twisted with spanner.
Fig. 3 is the structure chart of yoke plate, and yoke plate structure is a variety of, has aperture, yoke plate to be connected with insulator chain and pull rod on plate, root
Different yoke plates is used according to position of more hanging points suspension gold utensil on pipe busbar.
Fig. 4 is the structure chart of grading ring, and the structure of grading ring is a variety of, and needs are installed according to pipe busbar, can be in different extensions
Point uses the grading ring of corresponding construction.
Mounting means is shown in that Fig. 1, the both ends of pipe busbar 1 take two suspension gold utensils 2 respectively, and outer end hangs the yoke plate on gold utensil
One end is connect with pull rod, and the other end is connect with insulator chain, and the other end of insulator chain is connect with pylon, the other end of pull rod with
Yoke plate connection on the suspension gold utensil of intermediate hanging point, grading ring are mounted on yoke plate, and suspension gold utensil is covered with yoke plate and reaches equal
The purpose of pressure, adjustment rod length to optimum state.
Often hold between two hanging points using the gold utensils connection such as yoke plate 5, pull rod 3, pull rod be adjusted between two hanging points away from
From the junction of each yoke plate 5 carries out pressure shielding using grading ring 4, to reduce corona, with traditional pipe busbar both ends
It takes some suspended fixing modes to compare, in the length for not increasing insulator chain 6, greatly reduces pipe busbar amount of deflection.
Example the above is only the implementation of the present invention not thereby limits the scope of patent protection of the present invention, every profit
Equivalent structure or equivalent transformation made by description of the invention and its accompanying drawing content directly or indirectly use other than the present invention
Other related fields, can be considered the present invention scope of patent protection in.
