Description
Technical field
The invention belongs to field of power distribution, refer to a kind of low-voltage distribution cabinet that still can ensure Electrical Safety after being flooded especially.
Background technology
, all there is following defect, namely when being flooded in existing distribution system, water can enter power distribution cabinet inside from the housing slot of power distribution cabinet, element in power distribution cabinet is soaked in water, thus causes electric equipment normally to run, also can cause serious potential safety hazard simultaneously.
Now occurred the underground transformer that can meet immersion service requirement, but the high-low voltage electric power distribution cabinet matched with this kind of transformer still cannot meet the requirement of soaking and running.
Prior art proposes, and adopts hermetic power distribution cabinet to realize the object of waterproof.This hermetic power distribution cabinet adopts a can, after carrying out electrical equipment assembling, cabinet door is carried out sealing and fixes.And this structure still has following weak point, the electric elements in power distribution cabinet, when workpiece, can produce a large amount of heats, and this kind of power distribution cabinet cannot realize efficiently radiates heat.Therefore also have technology to propose, heat abstractor is set in full seal type distribution box 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 utilize pressure principle to solve waterproof problem, but the same Shortcomings of this technical scheme, namely because the water logging degree of depth is different, the air space retained above distribution cabinet is different.In practical situations both, because atmospheric pressure supports the reason of water column, the air above power distribution cabinet retains highly very little, that is, utilizes pressure principle cannot realize the object of waterproof completely at all.Further, even if this technical scheme can meet the requirement of waterproof, but air humidity in power distribution cabinet is very high, particularly at low temperature season, can form a large amount of condensations on electric elements, cause the problem such as short circuit, spark, cannot realize safety in production.
Therefore search out one power distribution cabinet use routinely under normal circumstances, automatically can carry out waterproof protection when being subject to water logging and ensure that the power distribution cabinet that element normally runs is the directions that those skilled in the art are making great efforts.
Summary of the invention
The object of the invention is to propose improvement project to existing power distribution cabinet, to ensure the Electrical Safety of power distribution cabinet under immersion condition, and the heat dissipation problem in immersion situation.
The present invention is achieved by the following technical solutions:
A kind of waterproof low-voltage power distribution cabinet, comprise with can the distribution cabinet of enclosures door, the back side edge of described cabinet and cabinet door be double-decker, have space between the bilayer of the back side edge of described cabinet, and cabinet is tightly connected between each limit; Cable and pipeline pass cabinet place through encapsulation process; Be provided with heat abstractor in described power distribution cabinet, below the front side cabinet door of described distribution cabinet, upper back be provided with heat radiation slotted eye; An electromagnetically operated valve is provided with in order to close heat radiation slotted eye near each heat radiation slotted eye place inside the cabinet of described power distribution cabinet; Be provided with the sealing strip of same cabinet door Four built in boundaries inside described distribution cabinet door, and be provided with compression type electromagnetically operated valve inside cabinet door; Be provided with liquid level monitor in described power distribution cabinet, liquid level monitor controls the startup of above-mentioned electromagnetically operated valve and heat abstractor.
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 is connected with one end of evaporator, and condenser connects compressor with the other end of evaporator.
In the cabinet of described power distribution cabinet, rear side is provided with absorber plate with holes, and described condenser is arranged between absorber plate and power distribution cabinet rear wall; Described absorber plate selects insulating heat-conduction material.
Described liquid level monitor is arranged at the bottom in the cabinet of power distribution cabinet, the alarm liquid level of described liquid level monitor lower than the foot of bottom element in power distribution cabinet to 1/2-2/3 of cabinet bottom surface height.
The present invention's beneficial effect is compared with the existing technology:
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 heat radiation of heat radiation slotted eye, 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 power distribution cabinet sealing, and is dispelled the heat by heat abstractor.

Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
As shown in Figure 1 to Figure 3, waterproof low-voltage power distribution cabinet, comprise with can the distribution cabinet 3 of enclosures door, the back side edge of described cabinet 3 and cabinet door be double-decker, have space between the bilayer of the back side edge of described cabinet; Cabinet door for power distributing cabinet is by being arranged on switch opens on cabinet door or closing cabinet door under normal circumstances, and the compression type electromagnetically operated valve 5 be arranged in cabinet door processes 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 described power distribution cabinet, on front side of described power distribution cabinet, the below of cabinet door is provided with heat radiation slotted eye 2, and power distribution cabinet upper back is provided with heat radiation slotted eye 21; Inside the cabinet of described power distribution cabinet, on front side of power distribution cabinet, the below of cabinet door and the heat radiation slotted eye place of power distribution cabinet upper back are respectively provided with an electromagnetically operated valve 61 in order to close heat radiation slotted eye 2 and heat radiation slotted eye 21; Inside described distribution cabinet door, four limits are provided with the fixing sealing strip 4 of same cabinet door, and are provided with compression type electromagnetically operated valve 5 inside cabinet door 1; Liquid level monitor 7 is provided with, the startup of liquid level monitor 7 Controlling solenoid valve and heat abstractor in described power distribution cabinet.
Described heat abstractor includes evaporator, condenser and compressor; Described condenser, compressor are arranged in distribution cabinet, and described evaporator is arranged on rear side of cabinet in double-deck gap, and described condenser is connected with one end of evaporator, and condenser connects compressor with the other end of evaporator.
In described distribution cabinet, rear side is provided with absorber plate with holes, described absorber plate selects insulating heat-conduction material manufacture, although absorber plate also can select metal group material manufacture, but consider not preferable alloy class material from security standpoint, described condenser is arranged between absorber plate and power distribution cabinet rear wall.
