Technical field
The utility model relates to a kind of transformer, and specifically a kind of cabling on cable rack mining transformer, belongs to mining transformer technical field.
Background technology
General mining transformer is by the device body being placed in oil tank of transformer, by high-low pressure binding post, high voltage is accessed to low-voltage output, and by high-low pressure terminal sealing in terminal box, to prevent that the electric arc that wiring or failure and other reasons cause from causing gas explosion in external world's contact.
As shown in Figure 1, traditional transformer is mostly both sides outlet, mainly by high and low pressure terminal box 2-1,1-1, and cable entry 3, device body 6 and fuel tank 7 form, and terminal box is arranged on transformer both sides, and cable entry is arranged in terminal box.This kind of structure, has following several defect:
1. high-low pressure binding post and shunting switch must be installed on device and hold oil tank wall both sides with it and be immersed in insulating oil, because of the reason of switch and connection terminal structure, cause oil tank of transformer need increase and be full of insulating oil, relatively waste transformer oil, cause the waste of resource;
Install time, need first device body is placed in fuel tank, then in fuel tank, connect, tap and height outlet, narrow space be not easy to operation;
3. due to both sides outlet, need installation height compression bonded line box, thereby occupy heat sink location, cause radiator to install, cause radiating effect poor, be easy to damage, useful life is short, and is not easy to maintenance.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of cabling on cable rack mining transformer, dwindles fuel tank volume, reduces the use of insulating oil, and saving resource is effectively convenient to maintenance, and good heat dissipation effect, long service life.
For solving the problems of the technologies described above, a kind of cabling on cable rack mining transformer of the utility model, comprises fuel tank, fuel tank cap, low pressure terminal box, high-voltage connection box, the high-voltage connection terminal that is arranged in high-voltage connection box, the low-voltage wiring terminal that is arranged in low pressure terminal box, shunting switch and device body; Described fuel tank is provided with pasta line; Described low pressure terminal box and high-voltage connection box are respectively equipped with cable entry; Described high and low pressure binding post is arranged on fuel tank cap upper surface through fuel tank cap, and described shunting switch is arranged on fuel tank cap lower surface; Described low pressure terminal box and high-voltage connection box are arranged in fuel tank cap, and described fuel tank cap is arranged on device body top, and device body is placed in fuel tank.
Further, the sidewall of fuel tank is provided with radiator.
Further, radiator is corrugated radiator.
Further, radiator is provided with two, is arranged on respectively on the outer wall of fuel tank both sides.
The utility model is cabling on cable rack mining transformer, compared with prior art, has the following advantages:
1. device body connects case lid, can integral hoisting, and in advance at the exterior complete device body of fuel tank, then integral hoisting enters fuel tank, convenient operation, saving of work and time;
2. high-low pressure binding post and shunting switch are arranged on device body top, have reduced the height of fuel tank, greatly reduce the consumption of transformer oil, have effectively saved resource, cost-saving;

Brief description of the drawings
Fig. 1 is prior art structural representation;
Fig. 2 is the utility model overall structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 2, a kind of cabling on cable rack mining transformer of the utility model, is mainly made up of fuel tank 7, fuel tank cap 7-1, low pressure terminal box 1, high-voltage connection box 2, the high-voltage connection terminal 2-1 that is arranged in high-voltage connection box 2, the low-voltage wiring terminal 1-1 that is arranged in low pressure terminal box 1, shunting switch and device body 6; Described fuel tank 7 is provided with pasta line 4; Described low pressure terminal box 1 and high-voltage connection box 2 are respectively equipped with cable entry 3; Described high and low pressure binding post 2-1,1-1 are arranged on fuel tank cap 7-1 upper surface through fuel tank cap 7-1, and described shunting switch 8 is arranged on fuel tank cap 7-1 lower surface; It is upper that described low pressure terminal box 1 and high-voltage connection box 2 are arranged on fuel tank cap 7-1, and described fuel tank cap 7-1 is arranged on device body 6 tops, and device body 6 is placed in fuel tank 7.
Improvement as the utility model to technique scheme, the sidewall of described fuel tank 7 is provided with radiator 5, has strengthened the heat radiation dynamics of transformer, greatly reduces the temperature of transformer, extends the useful life of transformer, saves use cost.
As preferred version of the present utility model, described radiator 5 is corrugated radiator, corrugated radiator good heat dissipation effect, and cheap, cost performance is higher.
As another preferred version of the present utility model, described radiator 5 is provided with two, is arranged on respectively on the outer wall of fuel tank 7 both sides, further strengthens heat radiation dynamics, extends transformer useful life.
Because device body of the present utility model 6 is connected as a single entity with fuel tank cap 7-1, can integral hoisting, thus when mounted can be in advance at the exterior complete device body 6 of fuel tank 7, then integral hoisting enters fuel tank 7, simple to operation, time saving and energy saving, cost-saving.
