Description
Technical field
The invention belongs to field of power distribution, refer to especially a kind of low-voltage distribution cabinet that after being flooded, still can ensure Electrical Safety.
Background technology
All there is following defective in existing distribution system, namely in the situation that be flooded, water can enter power distribution cabinet inside from the shell slit of power distribution cabinet, element in the power distribution cabinet is soaked in the water, thereby causes electric equipment normally to move, also can cause serious potential safety hazard simultaneously.
The underground transformer of immersion service requirement now occurred to satisfy, but the high-low voltage electric power distribution cabinet that matches with this class transformer still can't satisfy the requirement of immersion operation.
Prior art proposes, and adopts hermetic power distribution cabinet to realize the purpose of anti-water logging.This hermetic power distribution cabinet adopts a can, after carrying out the electrical equipment assembling, seals the cabinet door fixing.And this structure still has following weak point, and the electric elements in the power distribution cabinet can produce a large amount of heats, and this class power distribution cabinet can't be realized efficiently radiates heat when workpiece.Therefore also there is technology to propose, in the full seal type distribution box, heat abstractor is set and solves heat dissipation problem, but this requires the continuous operation of heat abstractor, causes the loss of energy.
Now also there is technology to propose, at power distribution cabinet outer cover one bucker, and utilizes pressure principle to solve anti-water logging problem, but the same Shortcomings of this technical scheme, namely because the water logging degree of depth is different, the air space of retaining above the distribution cabinet is different.Under actual conditions, support the reason of water column because of atmospheric pressure, the air of power distribution cabinet top retains highly very little, that is to say, utilizes pressure principle can't realize the purpose of anti-water logging fully at all.And even this technical scheme can satisfy the requirement of anti-water logging, but the air humidity in the power distribution cabinet is very high, particularly at low temperature season, can form a large amount of condensations on electric elements, causes the problems such as short circuit, spark, can't realize safety in production.
Therefore search out a kind of under normal circumstances routinely power distribution cabinet use, when being subject to water logging, can automatically prevent the water logging protection and guarantee that the power distribution cabinet of the normal operation of element is that those skilled in the art are in the direction of effort.
Summary of the invention
The objective of the invention is existing power distribution cabinet is proposed improvement project, to guarantee the Electrical Safety of power distribution cabinet under the immersion condition, reach the heat dissipation problem in the immersion situation.
The present invention is achieved by the following technical solutions:

Described heat abstractor includes evaporator, condenser and compressor; Described condenser, compressor are arranged in the cabinet of power distribution cabinet, and described evaporator is arranged in the space of cabinet back side edge, and described condenser links to each other with an end of evaporator, and condenser connects compressor with the other end of evaporator.
Rear side is provided with absorber plate with holes in the cabinet of described power distribution cabinet, and described condenser is arranged between absorber plate and the power distribution cabinet rear wall; Described absorber plate is selected insulating heat-conduction material.
Described liquid level monitor is arranged at the bottom in the cabinet of power distribution cabinet, and the alarm liquid level of described monitor is lower than in the power distribution cabinet foot of lower element to the 1/2-2/3 of cabinet bottom surface height.
The beneficial effect that the present invention compares with prior art is:
The power distribution cabinet of the technical program, in usual situation, each electromagnetically operated valve is in open mode, heat abstractor does not start, and power distribution cabinet relies on the louvre heat radiation, after liquid level monitor monitors liquid level and reaches alarm liquid level, start electromagnetically operated valve and heat abstractor, each closed electromagnetic valve is realized the power distribution cabinet sealing, and dispels the heat by heat abstractor.

Embodiment
The below describes embodiments of the invention in detail, and the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the present invention, and can not be interpreted as limitation of the present invention.
As shown in Figure 1 to Figure 3, the waterproof low-voltage distribution cabinet comprises that the back side edge of described cabinet 3 and cabinet door are double-decker, between the bilayer of the back side edge of described cabinet the space are arranged with distribution cabinet 3 that can the enclosures door; Generally cabinet door for power distributing cabinet is by being arranged on the switch opens on the cabinet door or closing the cabinet door, and the compression type electromagnetically operated valve 5 that is arranged in the cabinet door is processed opening, and cabinet is tightly connected between each limit, namely connects in the mode of not leaking between each limit of cabinet; Be provided with heat abstractor 8 in the described power distribution cabinet, upper lateral part is provided with heat radiation slotted eye (2,21) behind the below of described power distribution cabinet front side cabinet door and the power distribution cabinet; The heat radiation slotted eye place of upper lateral part respectively is provided with an electromagnetically operated valve 61 in order to close heat radiation slotted eye 21 behind the below of the inboard close power distribution cabinet front side of the cabinet of described power distribution cabinet cabinet door and the power distribution cabinet; Inboard four limits of described distribution cabinet door are provided with the fixing sealing strip 4 of cabinet door, and are provided with compression type electromagnetically operated valve 5 in cabinet door 1 inboard; Be provided with liquid level monitor 7 in the described power distribution cabinet, the startup of liquid level monitor 7 control electromagnetically operated valves and heat abstractor.
