When the flexible leads pass through the tension tower, the rigid jumping wire process is adopted; a section of aluminum pipe is arranged between the flexible leads; and the unsafe factors caused by the easy sloshing of the flexible leads are effectively avoided by utilizing the characteristics of the aluminum pipe such as heavy weight, uneasy sloshing and the like.
Description
Technical field
The utility model relates to the high voltage substation field, particularly relates to a kind of rigid jumper device that is used for strain tower.
Background technology
Because the developable hydroelectric resources of China nearly 2/3 is in western part, coal resources 2/3 in Shanxi, Shaanxi and the Inner Mongol; But the power load of China 2/3 but is distributed in the developed area of the coastal and Beijing-Guangzhou Railway in east to the east of along the line.Like this, just need be delivered to the big area, the central and east of electricity needs to the electric weight of energy base generating.
In order to reduce transmission losses, improve the transmission of electricity quality, China begins to develop the UHV transmission technology at present.Ultra-high voltage AC transmission is meant the ac transmission engineering and the correlation technique of 1000kV and above electric pressure.Characteristics such as the UHV transmission technology has at a distance, big capacity, low-loss and economy.Though the UHV transmission technology has above advantage,, power transmission line there is very high requirement because the electric pressure of ultra high voltage is very high.
Power transmission line is when crossing strain tower, because power transmission line is a flexible cord, weight is lighter, when high altitude wind is big, can shake, and is bigger as shaking amplitude, touches the brandreth of strain tower, just causes security incident easily, therefore, need take corresponding measure to address this problem.
The utility model content
Technical problem to be solved in the utility model provides a kind of rigid jumper device that is used for strain tower, and this rigid jumper device can prevent the excessive unsafe factor that causes of flexible conductor shaking amplitude when flexible conductor process strain tower.
The utility model discloses a kind of rigid jumper device that is used for strain tower, comprises two connecting plates that are separately positioned on the strain tower both sides, is connected with draught line respectively between two connecting plates and the strain tower cross-arm; The flexible conductor of strain tower both sides is fixedly connected on two drainage plates through two connecting plates respectively, fixedly connected one section aluminum pipe between two drainage plates.
Preferably, be connected with the load-bearing hanger between described drainage plate and the connecting plate.
Preferably, described aluminum pipe is two rigidity aluminum pipes that are arranged side by side.
Preferably, described rigidity aluminum pipe is formed by fixedly connecting by the multistage aluminum pipe.
Preferably, the length range of described rigidity aluminum pipe is 10m-25m.
Preferably, described flexible conductor is the lead without tension stringing and stringing.
Compared with prior art, the utlity model has following advantage:
The utility model when the strain tower, adopts rigid jumper technology at flexible conductor, and one section aluminum pipe is set between flexible conductor, utilizes the weight of aluminum pipe big, characteristics such as is difficult for rocking, and effectively avoids easily rocking the unsafe factor that causes because of flexible conductor.
Description of drawings
Fig. 1 the utility model rigid jumper device one embodiment;
Fig. 2 is the utility model rigid jumper lifting schematic diagram.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The utility model at flexible conductor when crossing strain tower, for preventing the excessive strain tower that touches of flexible conductor shaking amplitude, take rigid jumper technology, between flexible conductor, connect one section rigid wire that quality is bigger, to prevent the excessive unsafe factor that causes of flexible conductor shaking amplitude.
Referring to Fig. 1, the utility model rigid jumper device one embodiment is shown, rigid jumper device 10 comprises 11, two connecting plates of two draught lines 12, two drainage plates 13, flexible conductor 14, aluminum pipe 15, and two load-bearing hangers 16.Two connecting plates 12 are separately positioned on strain tower 17 both sides, side at strain tower 17, the front end of connecting plate 12 connects draught line 11 1 ends, draught line 11 other ends are fixed on the cross-arm (not shown) of strain tower 17,4 flexible conductors 14 are connected on 4 wiring points of connecting plate 12, through wiring point, be connected on two end points of drainage plate 13 again.The structure of strain tower 17 opposite sides is identical with this side.Fixedly connected aluminum pipe 15 between two drainage plates 13 of strain tower 17 both sides, the two piece rigidity aluminum pipes of aluminum pipe 15 for being arranged side by side, two ends are connected on the end points of two drainage plates 13.
The utility model flexible conductor 14 adopts rigid jumper technology during through strain towers 17,14 of flexible conductors one section aluminum pipe 15 is set, and utilizes the weight of aluminum pipe 15 big, characteristics such as is difficult for rocking, and effectively avoids easily rocking the unsafe factor that causes because of flexible conductor 14.
The utility model aluminum pipe 15 can be spliced by the short aluminum pipe of multistage, for guaranteeing the straight of rigidity aluminum pipe 15, when splicing, carries out horizontal alignment with theodolite (or horizontal tube).
Referring to Fig. 2, be the utility model rigid jumper lifting schematic diagram.During rigid jumper device 10 lifting, earlier will all the other devices except that flexible jumper 14 be linked to be hang on together after the integral body in place, with the minimizing work high above the ground.Main suspension centre during lifting should be located at the tie point of load-bearing hanger 16 and rigidity aluminum pipe 15, and with soft thing rigidity aluminum pipe 15 is wrapped up protection, prevents wearing and tearing; Simultaneously, the free end of load-bearing hanger 16 application rope carries out synchronous service hoisting.
After lifting puts in place, load-bearing hanger 16 is connected with connecting plate 12, Hui Songzhu lifting rope 20 bears whole rigidity aluminum pipe 15 weight by load-bearing hanger 17.
All flexible jumpers 14 of homophase wire jumper two ends are all with after corresponding sub-conductor strain insulator pipe is connected and fixed separately, the degree of speeding of flexible jumper 14 is adjusted by root with manpower, after adjustment is finished, with manpower flexible jumper 14 conductor spacers are installed from top to bottom, in installation process, to give much attention to the variation of flexible jumper 14 degree of speeding, and in time carry out the fine setting of flexible jumper 14 degree of speeding.
After the conductor spacer installation of flexible jumper 14, reaffirm that flexible jumper 14 degree of speeding print, break after errorless, and finish the crimping of flexible jumper 14 lower end drainage plates 13 in the high-altitude that the flexible jumper 14 of finishing crimping is connected and fixed by root and rigidity aluminum pipe 15 connecting plates.
