Abstract
The utility model discloses a kind of heat abstractor for box-type substation, it comprises cabinet and air grid, described cabinet is provided with several depressed parts, the ventilating opening coordinating described air grid is offered in described depressed part, described air grid is fixed in described ventilating opening, wherein, the air grid arranged outside of described depressed part has cover plate, has ventilation gap between the cabinet of described cover plate and described depressed part.The structural design of the above-mentioned heat abstractor for box-type substation, can effectively stop rainwater, dust enters in casing, simultaneously leave gap between cover plate and cabinet, still can carry out ventilation and heat in casing, and take up room little, structure simple, be convenient to install.
Description
Technical field
The utility model relates to a kind of heat abstractor, particularly relates to a kind of heat abstractor for box-type substation.
Background technology
Box-type substation is a kind of power distribution equipment, the functions such as high powered, transformer pressure-reducing, low-voltage distribution is organically combined, is arranged in a casing, electromechanical integration, totally-enclosed operation.Various instrument, switch, electronic modular unit etc. are provided with in box-type substation, along with the continuous firing of transformer station, instrument in case, electronic modular unit etc. can produce a large amount of heats, cause the temperature inside the box constantly to raise, too high temperature can cause instrument, electronic modular unit etc. normally to work.Again because instrument, electronic modular unit etc. in case are very high to dust, temperature, humidity requirement, therefore all adopt sealed type, the heat produced in the case of box-type substation will be made like this to be difficult to discharge.Heat dissipating method conventional at present uses blower fan or offers heat abstractor, but this radiating mode has shortcoming: the sealing destroying casing, make dust dust, the dust of static electrification is also had to enter in the casing of box-type substation by blower fan and heat abstractor, be attached on various components and parts and affect insulating properties, even short circuit causes the accident.Therefore a kind of can to dispel the heat and can the radiator structure of blocks dust and rainwater is needed.
Utility model content
The purpose of this utility model is to provide a kind of heat abstractor for box-type substation, its have take up room little, be convenient to the features such as installation, dustproof and rainproof, to solve the problems referred to above that box-type substation in prior art exists in heat radiation when use procedure.
For reaching this object, the utility model by the following technical solutions:
A kind of heat abstractor for box-type substation, it comprises cabinet and air grid, described cabinet is provided with several depressed parts, the ventilating opening coordinating described air grid is offered in described depressed part, described air grid is fixed in described ventilating opening, and wherein, the air grid arranged outside of described depressed part has cover plate, have ventilation gap between the cabinet of described cover plate and described depressed part, like this can ventilation and heat again can dustproof and rainproof.
Especially, described cover plate four side all rearwardly crimping, and be fixed in the plane of described depressed part, being embedded in four limits of described depressed part of gap is left in four sides of described cover plate.
Especially, described air grid is flap type, and Open Side Down, arranges in low inside and high outside mode, also can discharge, prevent from entering in casing when having a small amount of rainwater to be splashed into.
Especially, described cover plate is connected and fixed by bolt and nut.
The beneficial effects of the utility model are, compared with prior art the described heat abstractor for box-type substation is by the cover plate outside the air grid of flap type and grid, effectively prevent entering of rainwater, dust, leave gap between cover plate and cabinet simultaneously, ventilation and heat can be carried out in casing, and little, the structure of taking up room simple, be convenient to install.

In figure:
1, cabinet; 2, cover plate; 3, air grid; 4, ventilating opening; 5, bolt and nut; 6, depressed part.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Refer to shown in Fig. 1, Fig. 1 is the cutaway view of the heat abstractor for box-type substation that the utility model embodiment 1 provides.
In the present embodiment, a kind of heat abstractor for box-type substation comprises cabinet 1 and air grid 3, described cabinet 1 is provided with several depressed parts 6, the ventilating opening 4 coordinating described air grid 3 is offered in described depressed part 6, described air grid 3 is fixed in described ventilating opening 4, wherein, air grid 3 arranged outside of described depressed part has cover plate 2, has ventilation gap between described cover plate 2 and the cabinet 1 of described depressed part.
Described cover plate 2 four side all rearwardly crimping, and be fixed in the plane of described depressed part 6 by bolt and nut 5, described cover plate 2 four side is all left in four limits being embedded in described depressed part 6 in gap; In addition, described air grid 3 is flap type, and Open Side Down, arranges in low inside and high outside mode, also can get rid of in time, prevent from entering in casing when having a small amount of rainwater to be splashed into.
In use procedure, the described heat abstractor for box-type substation, leaves gap between described cabinet 1 and described cover plate 2, can realize ventilation and heat in casing; The setting of described cover plate 2, can effectively stop rainwater and dust; And little, the structure of taking up room simple, be convenient to install.
Above embodiment has just set forth general principle of the present utility model and characteristic; the utility model does not limit by above-mentioned example; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various change and change, and these changes and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
