Abstract
The utility model discloses an air-convection pipeline-type rainproof power box, which comprises a box body (1), a blower fan (3), and a sliding cover body (4). The power box is characterized in that the blower fan (3) is disposed on the box body (1), and that the sliding cover body (4) is provided with a shutter (5). The utility model is aimed at providing the air-convection pipeline-type rainproof power box, which is small in size, large in air flow, and high in speed of heat exchange.
Description
Technical field
The utility model relates to field of power supplies, relates in particular to the rainproof power pack of a kind of cross-ventilation duct type.
Background technology
Power supply box mainly is to provide operating power for vacuum circuit-breaker and other high-voltage switch gear.Power supply box all adopts input AC 220V or 380V through the silicon-controlled voltage regulation rectification, and the output direct current has many grades of adjustable currents of output dc voltage big characteristics or alternating voltage, carries out the function of single branch, single closing operation.
Under actual condition, power supply box often need be exposed under the natural environmental condition, and traditional rainproof power shell often adopts sealed type or half-sealed structure.Because the circuit of power supply box inside in the course of the work, can produce a large amount of heats, the accumulation of heat influences the useful life of power supply box, also can reduce the security performance of use simultaneously.Owing to there is above problem, some rainproof power shell manufacturers have also adopted some improvement, are included in enclosure interior and add blower fan, this kind mode causes the power shell volume excessive, adopt this kind power shell, not only waste material resource, and processing technology cost is higher.
The utility model content
The purpose of this utility model provides that a kind of volume is little, and air flow amount is big, and heat replaces the rainproof power pack of fireballing a kind of cross-ventilation duct type.
For realizing above purpose, the technical solution adopted in the utility model: the rainproof power pack of a kind of cross-ventilation duct type, it comprises box body (1), blower fan (3) and slip lid (4); It is characterized in that: described blower fan is installed on the box body (1), and described slip lid (4) is provided with shutter (5).
Under preferable performance, described box body (1) bottom air inlet openings area equals shutter (5) and goes out aperture area.
Under preferable performance, be connected by rail plate (6) between described box body (1) and the slip lid (4).
Under preferable performance, the air outlet of described slip lid (4) is provided with a protruding drip ring (7), and described shutter (5) bottom is provided with delivery port (8).
Under preferable performance, described box body (1) bottom is provided with ventilation flashing board (9).
Under preferable enforcement situation, described box body (1) is metal material or macromolecular material with slip lid (4).
The beneficial effects of the utility model:
1, because blower fan is installed on the box body, and described slip lid is provided with shutter, blower fan is aimed at shutter in practical work process, and shutter has prevented that effectively rainwater from entering power supply box inside, and causes the damage of circuit.
2, under preferable condition of work, be connected by rail plate between box body and the slip lid, thereby realized easy accessibility between box body and the slip lid.
3, under the bigger situation of rainfall, may there be the part rainwater to enter power supply box by the slit of shutter, the air outlet of described slip lid is provided with a protruding drip ring, has effectively stoped rainwater to enter power supply box by the slit of shutter.
4, in the coastal area, and the torrid areas, storm can appear usually.Storm may enter power supply box inside by the bottom air inlet mouth of rainproof power pack under the drive of blast.In such cases, be provided with the ventilation flashing board in described box body bottom.
5, described box body and slip lid are metal material or macromolecular material, adopt this kind material to realize the heat of circuit board generation and the exchange between the air to greatest extent in reality.
