Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
The present invention includes 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 and power distribution cabinet upper back are provided with heat radiation slotted eye (2,21); 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 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.
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 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, consider not preferable alloy class material from security standpoint, described condenser is arranged between absorber plate and power distribution cabinet rear wall.Liquid level monitor is arranged at the bottom in distribution cabinet, the alarm liquid level of described monitor lower than the foot of bottom element in power distribution cabinet to the 1/2-2/3 of cabinet bottom surface height.The alarm liquid level of monitor can adjust according to the needs of user, but its highest also should lower than the minimum position of electric elements in power distribution cabinet.Cable and pipeline etc. all carry out encapsulation process through the position of power distribution cabinet.
The specific works mode of power distribution cabinet of the present invention is: under normal conditions, namely comprise the rainy day when not having water to immerse, electromagnetically operated valve in power distribution cabinet is in opening, that is electromagnetically operated valve is open when not having action, now, be positioned at the louvre of power distribution cabinet front and rear with distribution cabinet and external connection, described louvre has rainwater-proof design, and now power distribution cabinet works when natural heat dissipation.
If now, position residing for power distribution cabinet is immersed gradually by water or other liquid, by Technology design requirement of the present invention, if in directly the power distribution cabinet designed by the technical program being gone in off the deep end, it is 1-3 minute that liquid immerses the time reaching power distribution cabinet liquid monitoring instrument alarm liquid level, this time also can change, these changes can not have influence on technical scheme of the present invention, these are used to technical scheme of the present invention is described, this alarm liquid level will have certain distance with the extreme lower position of element in power distribution cabinet.While monitor is reported to the police, start all electromagnetically operated valves in power distribution cabinet and heat abstractor, now closed electromagnetic valve, namely two place's louvres are closed and cabinet door is closed with cabinet, the closedown mode of cabinet door is similar to the water-stop door of ship class herein, and so far, whole power distribution cabinet all seals.At this moment, heat abstractor also starts, and is dispelled the heat by the cooling fluid in evaporator and condenser.
The type of alarm of liquid level monitor can be reported to the police by indicator light and sound this locality, and described indicator light is arranged at the outside of cabinet door, and can simultaneously by being arranged at the communicator remote alarms in cabinet, to maintain easily or the monitoring of administrative staff.
