The system can improve the repeated movement efficiency of the tested conducting wire in the corona cage, reduce wire replacing difficulty and ensure the testing performance.
Description
Technical field
The utility model relates to the facility in a kind of extra-high voltage direct-current test, particularly changes system about a kind of corona cage lead.
Background technology
The extra-high voltage corona cage is a critical facility in the extra-high voltage direct-current test base, is used for the research of multiple fission conductor corona characteristic.Corona cage test need be to the operation of wearing out of new lead, to obtain the lead identical with actual track.Aging operation has following two kinds of schemes: the one, carry out mandatory wearing out by lead being carried out physical means such as sandblast, poach, and Japanese at present corona cage adopts this method to carry out lead and wears out; The 2nd, new lead is destroyed burr by effluve, be placed on again and carry out unaccelerated aging in the physical environment, this scheme can access the aging effect identical with actual track.Because the corona cage length of China is long, employing scheme one has the following disadvantages: 1, equipment is many, and occupied ground is big; 2, investment cost height; 3, can't guarantee that the lead after the aging operation is identical with the aging effect of the lead of unaccelerated aging; Employing scheme two, then need the lead of test usefulness is moved between inside and outside the corona cage repeatedly, to check aging effect and to test repeatedly, but repeatedly the mobile employing between inside and outside the corona cage of several tons lead is done it by hand and carry it on one's shoulder for weighing, then not only the low difficulty of efficient is big, and the destructible conductive line surfaces situation that contacts of people and lead, thereby influence experimental performance.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides and a kind ofly makes the lead in the corona cage change system at the corona cage lead that moves repeatedly between inside and outside the corona cage under the situation of not having wearing and tearing.
For achieving the above object, the present invention takes following technical scheme: a kind of corona cage lead restringing system is characterized in that comprising: a plurality of shaft towers, and each described shaft tower branch is located at described corona cage both sides, is respectively arranged with a plurality of insulator chains on each described shaft tower; Two elevator stretching all-in-ones are separately positioned on the outside of each described shaft tower of described corona cage both sides; The couple of conductor support is arranged on the described shaft tower of described corona cage one side and wherein between the described elevator stretching all-in-one.
Described shaft tower is provided with the construction equipment that is used for fixing and adjusts lead.
Two described elevator stretching all-in-ones are connected with lead by traction rope.
This use is novel owing to take above technical scheme, it has the following advantages: 1, the utility model has improved lead repeatedly mobile efficient between inside and outside the corona cage; 2, the utility model has reduced the difficulty that lead moves between inside and outside the corona cage repeatedly; 3, the utility model can avoid the conductive line surfaces situation to be subjected to the influence that contacts between people and the lead, to guarantee experimental performance.

Embodiment
In order to describe structure of the present utility model, characteristics and effect in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.
As Fig. 1～shown in Figure 3, the utility model is used to the corona cage restringing, comprises a plurality of shaft towers 1 that are arranged on corona cage 4 both sides, is arranged on a plurality of insulator chains 2 on the shaft tower 1, couple of conductor support 5, two elevator stretching all-in- ones 61,62 and some assembly cover construction equipment.
As shown in Figure 1, shaft tower 1 is arranged on corona cage 4 both sides, and shaft tower 1 is as the fulcrum of corona cage 4 both sides, the hang oneself construction equipment of similar pulley group effect of shaft tower 1.Be anchored at shaft tower 1 on by insulator chain 2 tested lead 3 and adjust the lead state by the construction equipment of similar pulley group.Insulator chain 2 can make at the trial between lead 3 and the shaft tower 1 of band high-tension electricity and guarantee to insulate.
As shown in Figure 2, in a side of corona cage 4, between shaft tower 1 and the elevator stretching all-in-one 62 according to from low to high be sequentially set with couple of conductor support 5, but many leads that need test of parallel suspend on the wire support 5.The height of support 5 can be guaranteed still not contact with ground after lead 3 hangs.The distance that two wire supports are 5 is according to the Design of length of test lead, and the width of support 5 is by the number decision of lead, and system does not have direct relation with the lead replacing.In the present embodiment, the distance that two row's wire supports are 5 is approximately 80 meters, and the width of support 5 is about 25 meters with many leads of convenient suspension.
As shown in Figure 3, in the outside of corona cage 4 both sides shaft towers 1 and support 5, two elevator stretching all-in-one 61,62, two elevator stretching all-in- ones 61,62 with traction rope are set respectively are used for traction and unclasp lead 3.Elevator stretching all-in-one 61,62 is connected with lead 3 by traction rope, as required lead 3 is sent into or is derived in the corona cage 4.In the time will sending into lead 3 in the corona cage 4,61 take-ups of elevator stretching all-in-one, another 62 of elevator stretching all-in-one unclasps lead 3, after lead 3 enters in the corona cage 4, just lead 3 is fixed on the shaft tower 1 by insulator chain 2, and inserts power supply.After off-test, lead 3 is separated from shaft tower 1,62 take-ups of elevator stretching this moment all-in-one, 61 unwrapping wire of another elevator stretching all-in-one shift out lead 3 from corona cage 4, until lead 3 is transported on the wire support 5, again traction rope and lead 3 are got loose, lead 3 can be placed on the support 5, and traction rope can connect other and tried lead, and repeating said process can be transported in the corona cage 4 by two elevator stretching all-in-ones 61,62.The power of two elevator stretching all-in-ones and construction equipment is selected the specification that is complementary according to the weight of actual test lead, there is no particular determination.
The above; it only is a kind of better embodiment of the present utility model; those skilled in the art can make amendment and equivalent transformation according to the utility model instructions, claims and accompanying drawing, and such modification and conversion all should be included within the scope of patent protection of the present utility model.
