Description
Technical field
The present invention relates to a kind of electric power auxiliary equipment, particularly a kind of heat abstractor of box type transformer low-pressure chamber.
Background technology
The change distribution combined electrical apparatus application of the types such as box type transformer (being called for short " case change ") is increasingly extensive, especially European-type box becomes, its inner member connection and reasonable arrangement, inspection travel is convenient, for transformer room be all provided with special thermal window, radiator fan carries out cooling.But but often there is the bad situation of heat radiation in the low tension switch chamber that European-type box becomes, especially summer, under the heat and Exposure to Sunlight thermogenic action of transformer, low tension switch room temperature usually reaches more than 80 DEG C, the ambient temperature limit value allowing considerably beyond equipment such as breaker of plastic casing, not only causes the aging quickening of inner member, also often causes the accident of switch malfunction tripping operation, not only a large amount of waste maintenance manpower and materials, return user and bring unnecessary trouble.For example, for breaker of plastic casing, its specified operating ambient temperature must not be greater than 45 DEG C, under the ambient temperature of 80 DEG C, the circuit breaker that electronics is de-mouthful will be easy to because of the aging malfunction tripping operation of electronic component, the de-mouthful electric current of circuit breaker that heat is de-mouthful will decay to below 60% of rated value, the probability of malfunction tripping operation is high, and case becomes, and the fire causing because of long-term overheated component ageing is quite a few to be seen.
But dependence prior art; the heat dissipation that can carry out case step-down pressure chamber at present is only confined to offer and strengthen louvre, radiator window; or provided with fan; although the means of this increase heat dispersion can reduce ambient temperature; but also extraneous dust, steam etc. together can be brought into low-pressure chamber simultaneously; can cause again inner dust stratification, enter tide, the other problems such as transformer noise leaks, certainly will bring adverse effect to the operation of the low-pressure chamber that contains secondary protection function.In sum, always undecided to the heat dissipation problem of case step-down pressure chamber.
Summary of the invention
The object of this invention is to provide a kind of heat abstractor of box type transformer low-pressure chamber, guarantee in low-pressure chamber being carried out to fully heat radiation, the pollutant in outside air can be introduced into the low-pressure chamber inside of box type transformer, the noise that also can not cause box type transformer leaks, and has effectively improved the operational reliability of box type transformer in summer high temperature environment.
For achieving the above object, technical scheme of the present invention is to provide a kind of heat abstractor of box type transformer low-pressure chamber, and it comprises a shell, and is all arranged on described enclosure: air-air heat exchanger, and it has an air inlet and a return air inlet; Cooling fan, it is arranged on the bottom of described air-air heat exchanger, and is connected with the radiating fin of described air-air heat exchanger; Circulating fan, it is arranged in the air inlet of described air-air heat exchanger or in return air inlet; Automatic control module, it is arranged on the top of described air-air heat exchanger, the internal temperature that records air-air heat exchanger higher than set threshold value time, control and start cooling fan.
The heat abstractor of box type transformer low-pressure chamber of the present invention also comprises support, it is arranged on the back of shell, for this heat abstractor is mounted and fixed on to the external wall of box type transformer low-pressure chamber, and make to separate between this heat abstractor and the external wall of box type transformer low-pressure chamber.
Described air inlet and return air inlet are all arranged on the back of shell, are inserted into the inside of low-pressure chamber by the external wall of box type transformer low-pressure chamber.
On the front and back of described shell, be respectively arranged with front shutter and rear shutter, wherein before the corresponding setting of air outlet of fan shutter and described cooling fan.
The front of described shell is also provided with a key lock.
The front of described shell is also provided with some indicator lights.
The heat abstractor of box type transformer low-pressure chamber provided by the present invention, not only overcome the problem that traditional box transformer low voltage chamber lacks heat abstractor, and can guarantee in low-pressure chamber being carried out to fully heat radiation, the low-pressure chamber inside that pollutant in outside air can be introduced into box type transformer, also can not cause that the noise of box type transformer leaks.The present invention can effectively reduce at least 25 DEG C by the temperature in low-pressure chamber, ensures that the indoor equipment of box transformer low voltage can, because of overheated and damage or tripping operation, not improve the operational reliability of box type transformer in summer high temperature environment greatly.

Embodiment
Below in conjunction with Fig. 1～Fig. 3, describe a preferred embodiment of the present invention in detail.
As shown in Figure 2, the heat abstractor of box type transformer low-pressure chamber provided by the present invention, it comprises a shell 6, and is all arranged on described shell 6 inside: air-air heat exchanger 1, it has an air inlet 4 and a return air inlet 5; Cooling fan 3, it is arranged on the bottom of described air-air heat exchanger 1, and is connected with the radiating fin of described air-air heat exchanger 1; Circulating fan 2, it is arranged in the air inlet 4 of described air-air heat exchanger 1 or in return air inlet 5; As shown in Figure 3, in the present embodiment, described circulating fan 2 is arranged in the air inlet 4 of air-air heat exchanger 1; Automatic control module 7, it is arranged on the top of described air-air heat exchanger 1, automatically control for cooling fan 3 is carried out to temperature, the internal temperature that records air-air heat exchanger 1 higher than set threshold value time, control and start cooling fan 3.
As shown in Figure 3, the present invention also comprises support 9, it is arranged on the back of shell 6, for the heat abstractor of described box type transformer low-pressure chamber being mounted and fixed on to the external wall of box type transformer low-pressure chamber, and make to separate certain distance between this heat abstractor and the external wall of box type transformer low-pressure chamber, guarantee heat sink interior and outside circulation of air.
As shown in Figure 3, described air inlet 4 and return air inlet 5 are all arranged on the back of shell 6, are inserted into the inside of box type transformer low-pressure chamber by external wall, participate in circulation cooling for the air extracting in low-pressure chamber.
