Abstract
The utility model relates to an external structure of a detachable load switch. Three independent on-load tap changers are arranged outside the long axis direction of a transformer tank, the transformer tank is hermetically connected with the oil tanks of the on-load tap changers through flanges, and the transformer tank and the oil tanks of the on-load tap changers are completely communicated; a pressure regulating wire of the transformer body is connected with the wires of the on-load tap changers through wire connecting terminals. The external structure provided by the utility model is simple and easy to realize, a railway transportation condition which severely requires a converter transformer body in length and width directions can be met by dismounting the oil tanks of the on-load tap changers in the process of transporting products, so that the situation that high-end products are difficult to transport can be effectively relieved.
Description
Technical field
The utility model relates to a kind of converter transformer loaded switch, specifically a kind of detachable loaded switch external structure.
Background technology
China's energy resources distribute and are contrary distribution with economic development, water power is mainly distributed in southwest, coal electricity is mainly distributed in the Northwest, and power load is mainly distributed in developed regions, middle part, east, therefore be necessary in China electric power resource to be realized and being distributed rationally, to ensure the fast development of national economy.And high voltage direct current transmission project has very outstanding advantage aspect remote large capacity electric energy transmission of electricity and power system interconnection.Along with the development of Domestic Direct Current Transmission engineering, converter transformer also constantly increases as the topmost device requirement amount of current conversion station, due to the raising of electric pressure and the increase of capacity, UHV has all reached the limit of existing railway transport capacity aspect weight and volume, has restricted comprehensive fast development of China's DC transmission engineering.In order to accelerate the development of China's DC transmission engineering, adopt a kind of converter transformer of detachable loaded switch external structure, with the railway transportation condition that meets the demands harsh, very urgent.
Conventional converter transformer adopts two stem stem modes, and two on-load voltage regulating switchs 2 are placed on product end, as shown in Figure 1.Along with the increase of converter transformer capacity, increasing of voltage, in order to meet railway transportation condition, if also adopt two conventional stem stem modes, when transportation, Width transfinites, and has adopted the mode of three stem stems for this reason, if but loaded switch is also placed on termination, transfinite at length direction, cannot meet the condition of railway transportation.
Utility model content
Cannot meet the weak points such as the condition of railway transportation for converter transformer in prior art, the technical problems to be solved in the utility model is to provide a kind of detachable loaded switch external structure that can all meet at length and Width railway transportation condition.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of detachable loaded switch external structure of the utility model, adopts three independently on-load voltage regulating switchs, and is arranged on oil tank of transformer long axis direction outside, and oil tank of transformer is tightly connected by flange and on-load voltage regulating switch fuel tank, and two parts are communicated with completely.
Transformer body pressure regulation lead-in wire is connected by lead-in wire binding post with each on-load voltage regulating switch lead-in wire.
The utlity model has following beneficial effect and advantage:
1. the utlity model has simple in structurely, be easy to the feature that realizes, by adopting three independently on-load voltage regulating switchs, and be arranged on body fuel tank outside, by loaded switch oil tank flange with body fuel tank dress; When Product transport, pull down loaded switch fuel tank, just can all meet converter transformer body is required to harsh railway transportation condition at length and Width, effectively alleviated high-end product and transported difficult situation, accelerate the development of China's DC transmission engineering.
Accompanying drawing explanation
Fig. 1 is loaded switch arrangement schematic diagram in prior art:
Fig. 2 is the detachable loaded switch external structure of the utility model schematic diagram.
In figure: 1 is oil tank of transformer, 2 is on-load voltage regulating switch, and 3 is on-load voltage regulating switch fuel tank.
Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figure 2, a kind of detachable loaded switch external structure of the utility model, adopt three independently on-load voltage regulating switchs 1, and be arranged on outside oil tank of transformer 1 long axis direction, oil tank of transformer 1 is tightly connected by flange and on-load voltage regulating switch fuel tank 3, and oil tank of transformer 1 is communicated with completely with on-load voltage regulating switch fuel tank 3.Transformer pressure regulation lead-in wire is with it connected by lead-in wire binding post with each on-load voltage regulating switch lead-in wire.
In the present embodiment, on oil tank of transformer 1 long axis direction sidewall, be provided with three mounting flanges, on the sidewall of each on-load voltage regulating switch fuel tank 3, be also provided with flange, coordinate load is connect with the flange on oil tank of transformer 1.
In the time of shop test, converter transformer body fuel tank fixes dress by flange with loaded switch fuel tank, and the pressure regulation lead-in wire of device body inside is connected and fixed by the loaded switch lead-in wire in binding post and loaded switch fuel tank.Test complete, when the change of current becomes body transportation, first transformer oil is emitted, open on-load voltage regulating switch 2 lead-in wire and the transformer body pressure regulation binding post being connected that goes between, and each terminal is fixed in factory, open adpting flange simultaneously, pull down three on-load voltage regulating switch fuel tanks 3, the railway transportation condition that the high-end converter transformer body that removes like this loaded switch fuel tank just can all meet the demands harsh at length and Width.
Product is transported to behind scene, the conveying cover plate of three mounting flanges is removed, three loaded switch fuel tanks are fixed dress successively with body fuel tank, converter transformer device pressure regulation lead-in wire is with it connected to shielding with each on-load voltage regulating switch lead-in wire by lead-in wire binding post simultaneously and fixes.
Claims (2)
1. a detachable loaded switch external structure, it is characterized in that: adopt three independently on-load voltage regulating switchs (2), and be arranged on outside oil tank of transformer (1) long axis direction, oil tank of transformer (1) is tightly connected by flange and on-load voltage regulating switch fuel tank (3), and two parts are communicated with completely.
