The radiating protection structure comprises a box body, wherein a dry type transformer, a high-voltage power distribution device and a low-voltage power distribution device are arranged in the box body which is made of metal sheets. An air feeding machine is arranged at the top of the box body, and air fed by the air feeding machine passes through the dry type transformer, the high-voltage power distribution device and the low-voltage power distribution device in the box body. Air return passages are arranged at the bottom of the box body, inlets of the air return passages are distributed all around the bottom of the box body, and outlets of the air return passages are connected with an air discharging machine. Air fed into the box body moves from top to bottom, and the inlets of the air return passages are distributed all around the bottom in the box body so that the air in the box body can enter the air return passages in a cover-shaped mode, the air blown into the box body can move all around in a diffusing mode so as to cover all directions in the box body, heat in the box body can be taken away effectively, temperature in the box body can be even, and the radiating protection structure of the box-shaped transformer is safe to use, simple in structure, scientific and reasonable, easy to manufacture and low in cost.
Description
Technical field
The utility model relates to the transformer technology field, especially relates to box type transformer.
Background technology
At present; at skyscraper; commercial center; theater; hospital; the hotel; the tunnel; subway; the underground power station; laboratory; the station; harbour; the airport; important place such as assembly transformer substation; adopted volume little; in light weight; low noise and low-loss box type transformer; box type transformer is with transformer; high voltage distribution installation; low-voltage distribution equipment is integrated in the casing; transformer is generally dry-type transformer; and dry-type transformer and high voltage distribution installation; low-voltage distribution equipment all can produce heat in the course of the work; so that the temperature in the casing raises; in order to protect the use of transformer; prevent unexpected the generation; usually need to use blower fan that the case inner part is dispelled the heat; and in the prior art; the mode that blower fan dispels the heat and normally directly advances directly to go out the case inner part; radiating surface is little; so that the uneven defective of heat radiation in the case occurs, still fail effectively to solve problem of temperature rise.
The spirit that the applicant is adhering to the research innovation, keeping on improving is utilized its professional eye and professional knowledge, works out a kind of heat radiation protection structure that promotes the box type transformer of radiating effect.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and reaches comprehensive blowing heat radiation in the casing, uses the heat radiation protection structure of safer box type transformer.
For achieving the above object, the utility model adopts following technical scheme:
The heat radiation protection structure of box type transformer, comprise the casing that is built-in with dry-type transformer, high voltage distribution installation and low-voltage distribution equipment, casing is made by sheet metal, and the casing top is provided with the air intake machine, air intake machine air-supply flow through dry-type transformer, high voltage distribution installation and low-voltage distribution equipment in the case; Bottom at casing is provided with return air channel, and around the entrance of return air channel was distributed in the bottom half, the outlet of return air channel was connected to out blower fan.
Described air intake machine air-supply is earlier through entering in the casing behind dedusting, the dehydrating unit again, and dedusting, dehydrating unit are installed in the casing top.
Also be provided with the air intake machine on the described casing, go out the temperature controller that blower fan is connected.
The entrance of described return air channel is mesh-structured.
Describedly go out the side that blower fan is arranged on bottom half.
The heat radiation protection structure of the box type transformer that the utility model provides; the wind that its air intake machine is sent in the case is mobile from top to bottom; and the entrance of return air channel is distributed in around the case inner bottom part; make the wind in the case be the hood-shaped return air channel that enters, thereby diffusion is mobile around reaching the wind that is blown in the case, covers each orientation in the case comprehensively; effectively take away heat in the case; make the temperature inside the box more even, better heat-radiation effect is used safer.
The utility model also increases dedusting, dehydrating unit and temperature controller, thereby effectively prevents dust and steam from entering in the case and influence electronic unit case in, protection and the use of prolongation parts; And temperature controller can start the air intake machine, go out blower fan according to temperature rise situation in the case, reaches the effect of automatic monitoring and effective energy savings, has positive social benefit and economic benefit.
The utility model advantage again is simple in structure, and is scientific and reasonable, easily makes, with low cost.
Description of drawings:
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult shown in Figure 1ly, the heat radiation protection structure of the relevant box type transformer of the utility model comprises the casing 1 that is built-in with dry-type transformer, high voltage distribution installation and low-voltage distribution equipment, and casing 1 is made by sheet metal, makes easily; Casing 1 top is provided with air intake machine 2, and air intake machine 2 air-supply flow through dry-type transformer, high voltage distribution installation and low-voltage distribution equipment in the case can be done ventilative compartment in the casing 1 and arrange dry-type transformer, high voltage distribution installation and low-voltage distribution equipment; Be provided with return air channel 11 in the bottom of casing 1, around the entrance 111 of return air channel 11 was distributed in casing 1 bottom, the outlet of return air channel 11 was connected to out blower fan 3; Go out the side that blower fan 3 is arranged on casing 1 bottom, 111 of entrances are mesh-structured, are conducive to collect return air.Like this, during work, the wind that air intake machine 2 is sent in the case is mobile from top to bottom, and the entrance of return air channel is distributed in around the case inner bottom part, makes the wind in the case be the hood-shaped return air channel that enters, thereby diffusion is mobile around reaching the wind that is blown in the case, cover each orientation in the case comprehensively, effectively take away heat in the case, make the temperature inside the box more even, better heat-radiation effect is used safer.Go out 3 side air-out from casing 1 bottom of blower fan, overcome traditional defective of directly going out directly advanced, promote result of use.
