Abstract
The utility model provides a spiral arm type test hanging bracket for high-pressure tests. The spiral arm type test hanging bracket comprises a cement beam, wherein two fixed support steel plates are fixed to the cement beam; a rotating shaft is arranged on the two fixed support steel plates; a simulation pole and tower cross arm cantilever is fixed to the rotating shaft; and a plurality of fixed points are arranged at the bottom of a simulation pole and tower cross arm. According to the spiral arm type test hanging bracket for the high-pressure tests, the simulation pole and tower cross arm is fixed to the cement beam in a rotary mode, the simulation pole and tower cross arm can rotate to the using position with the rotation of the rotating shaft during the tests, and rotates to the position in which the simulation pole and tower cross arm is parallel to a building when the simulation pole and tower cross arm is not used, so other jobs are not obstructed and influenced while the simulation pole and tower cross arm meets the requirements of the tests. The spiral arm type test hanging bracket has a simple structure and is less in floor space.
Description
[technical field]
The utility model relates to a kind of high-potting and tests suspension bracket with swing-arm type.
[background technology]
Along with development and national economy; The rapid increase of power demand; The usage quantity of China's electric product is improving constantly; Urban and rural power grids construction and upgrading, Three Gorges Projects, " transferring electricity from the west to the east " and national cross-region the extra-high voltage networking that will carry out, all will create conditions for the development of more special, extra high voltage network and transformer station, current conversion station etc., the construction of these engineerings brings unprecedented opportunities and challenge also for the development of switch and insulator industry.Nowadays China's electrical network will be realized from the leap of high pressure to extra-high voltage, and in extra-high voltage grid was built, the transformer station of each grade all be unable to do without insulator.
Because of need further perfect to the type approval test condition of suspended insulator; According to GB GB/T775.2-2003 " insulator test method (electrical test method) "; Test product is hung vertically on the simulation shaft tower and cross-arm of ground connection by regulation; Cross-arm is intended with horizontal component dies, and test product should be at the one of which end, and the other end is the vertical member of simulation shaft tower.Each member is at least 20% of test product string length towards the width of the face of test product, and is not less than 400mm.The distance of test product axis to the vertical member of simulating shaft tower is 1.2～1.5 times of test product string length.Test product peak to the distance at the minimum position of horizontal member of simulating cross-arm is about 300mm, and simulation shaft tower cross-arm terrain clearance can make the conductor terrain clearance be about 1.5 times of the test product string length at least, and is not less than 6m.Other objects must not be long less than 1.5 times of strings from the distance of test product.The experimental enviroment in present existing high voltage control laboratory hall can't satisfy above condition.
[utility model content]
The purpose of the utility model provides the few high-potting of a kind of area occupied again simple in structure and tests suspension bracket with swing-arm type.
To achieve these goals, the utility model adopts following technical scheme:
A kind of high-potting is tested suspension bracket with swing-arm type, comprises the cement beam, is fixed with two blocks of fixed support steel plates on the cement beam; Turning axle is installed on two blocks of fixed support steel plates; Simulation shaft tower cross-arm cantilever is fixed on the turning axle; Simulation shaft tower cross-arm bottom is provided with a plurality of point of fixity.
Said high-potting also comprises first drawing pull bar and second drawing pull bar with swing-arm type test suspension bracket; First drawing pull bar, one end connects the turning axle top, and the other end connects the cantilevered distal end of simulation shaft tower cross-arm; Second drawing pull bar, one end connects the turning axle top, and the other end connects the middle part of simulation shaft tower cross-arm.
Compared with prior art; The utlity model has following advantage: a kind of high-potting of the utility model is tested suspension bracket with swing-arm type; The shaft tower cross-arm is rotatable to be fixed on the cement beam through simulating, and simulation shaft tower cross-arm can rotate to the use location along with the rotation of turning axle during test; Rotate to and build the body parallel position when not using, when satisfying the test needs, do not hinder again and influence carrying out smoothly of other work; Simple in structure, floor area is few.After having adopted this test suspension bracket, promptly can satisfy the requirement of GB GB/T 775.2-2003, again can be fixing on the wall suspension bracket, simple, practical, novel, reliable, thus satisfy the test of different voltage grade products.
[description of drawings]
Fig. 1 is the structural representation of the utility model.
[embodiment]
See also shown in Figure 1ly, a kind of high-potting of the utility model comprises cement beam 1, two blocks of fixed support steel plates 2, two drawing pull bar 4 and simulation shaft tower cross-arms 6 with swing-arm type test suspension bracket; Be embedded with two blocks of fixed support steel plates 2 on the cement beam 1, a turning axle 7 is installed between the fixed support steel plate 2, be fixed with a simulation shaft tower cross-arm 6 on the turning axle 7.In two drawing pull bar 4 one, an end connects turning axle 7 tops, and the other end connects the cantilever end of simulation shaft tower cross-arm 6; Another root drawing pull bar 4, one ends connect turning axle 7 tops, and the other end connects the middle part of simulation shaft tower cross-arm 6.Simulation shaft tower cross-arm 6 bottoms are provided with a plurality of point of fixity 5.
The utility model is fixed on fixed support steel plate 2 on the cement beam 1; With this support and root point as simulation shaft tower cross-arm 6; During test, simulation shaft tower cross-arm 6 can rotate to the use location along with the rotation of turning axle 7; Rotate to and build the body parallel position when not using, when satisfying the test needs, do not hinder again and influence carrying out smoothly of other work.For overcoming the stress deformation that simulation shaft tower cross-arm 6 long (about 7m) cause, designed adjustable drawing pull bar 4 to guarantee the reliability of simulation shaft tower cross-arm 6 when hanging test product suspended insulator 9.Several test product lifting point of fixity 5 are housed so that lift the test product 9 of different electric pressures on the simulation shaft tower cross-arm 6.Test product 9 is suspended on the simulation shaft tower cross-arm 6 through switching connections/switching suspender 8, conductor 10 through the connection/switching suspender 8 of transferring be connected test product 9 below, and simulate 6 one-tenth 90 ° of shaft tower cross-arms.
Above-mentioned instance only is a kind of preferred implementation of the utility model; Be not to be that protection domain to the utility model limits; All any simple modification and equivalent structures of being done according to the utility model spirit are changed or are modified, and all should be encompassed within the protection domain of the utility model claim.
