Background technique
Power distribution cabinet sub-power power distribution cabinet and light distribution cabinet, metering cabinet, are widely used in power plant, substation, power distribution station Equal places, also can be used as the protection and observing and controlling of the voltage and current of system in voltage class switchgear between the 70V-220V of part, are The final stage device of distribution system.Power distribution cabinet is the general designation of motor control center.Power distribution cabinet use is load is more dispersed, circuit Less occasion;The occasion that motor control center concentrates for load, circuit is more.They are a certain upper level controller switching equipment The electric energy of circuit distributes to nearest load.This grade of equipment reply load provides protection, monitoring and control.It is usually set in power distribution cabinet Set the fever types electric power component such as singlechip controller, current transformer, voltage transformer, relay, UPS, component itself Fever will cause the temperature in power distribution cabinet raising, and then influence component itself working condition, lead to the frequency of power failure Hair.
It under normal conditions, is all that exhaust fan is installed on power distribution cabinet to realize cooling, the most commonly used is the wind with axial flow blower Fan, but when fan work, external dust, greasy dirt and pernicious gas can also enter in power distribution cabinet therewith, by component surface Electrostatic Absorption is accumulated over a long period, and has certain corrosion to component, route etc., while influencing its heat dissipation performance.The dust of aggregation by The phenomenon of component short circuit can also be caused after tide, the power distribution cabinet working time is longer, and above-mentioned problem is more, and accumulation is to a certain extent The catastrophic failure of control section will be caused afterwards.The patent document of Authorization Notice No. CN207910275U discloses a kind of with heat dissipation The power distribution cabinet of dedusting function, including power distribution cabinet shell, are equipped with control layer between power distribution cabinet inner walls top, inside control layer Control module is installed, control layer lower end is provided with fan, and there are two the power distribution cabinet shell side inner wall settings below control layer Mounting plate, the power distribution cabinet shell other side inner wall below control layer are oppositely arranged there are two mounting plate, between the mounting plate of two sides It is movably installed with first partition, is provided with second partition below first partition, power distribution cabinet shell two sides outer wall is relatively set with scattered Hot mouth is hinged with cover board on thermovent, and multiple ventilation gaps are provided with above thermovent, and power distribution cabinet inner walls correspond to ventilation The position in gap is provided with the first dirt filtrating screen, and disposal box is provided on the bottom plate of power distribution cabinet shell, and disposal box upper end is provided with out Mouthful, disposal box opening is provided with unidirectional spring hinge.The structure is dust-proof by the way that dirt filtrating screen progress is arranged at ventilation gaps, but It is dirt filtrating screen in long-time use process, easily blocks, influence intake efficiency.
Utility model content
In view of this, the purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of Unpowered ventilation formula and match Electric cabinet, the application extends outwardly air inlet by blast pipe, and blast pipe is obliquely installed, pre- preventing rainwater from flowing backward, setting The phenomenon that Air Filter in the end of blast pipe can passively be washed away on rainy day, pre- anti-clogging occurs, and guarantees that air inlet is suitable Freely.
In order to achieve the above objectives, the utility model uses following technical scheme:
Including cabinet body and the rain visor held on the cabinet is arranged, on the top plate of cabinet body in a kind of Unpowered ventilation formula power distribution cabinet Unpowered blast cap is set, and the unpowered blast cap is located at the lower section of rain visor, and air inlet, institute is arranged in the lower part of the side baffle of cabinet body Air inlet setting blast pipe is stated, the blast pipe is obliquely installed, and the end sleeve of the blast pipe sets Air Filter.
Further, catch basin is arranged in the edge of the rain visor, and drainpipe, the row is arranged in the bottom of the catch basin Water pipe includes the first drainpipe and the second drainpipe for being rotatably connected on the first drainpipe lower end, the lower end of second drainpipe It can rotate to the top of Air Filter.
Further, the lower end of second drainpipe is flat mouth shape.
Further, the upper end of the Air Filter and blast pipe are socketed.
Further, the rain visor is herringbone or trapezoidal shape structure.
The beneficial effects of the utility model are:
1. unpowered blast cap to be arranged in the lower section of rain visor, pre- rainwater leakage prevention;Air inlet is passed through air inlet by the application The phenomenon that pipe extends outwardly, and the Air Filter that the end of blast pipe is arranged in can passively be washed away on rainy day, pre- anti-clogging Occur, guarantees that air inlet is smooth, and blast pipe is obliquely installed, pre- preventing rainwater from flowing backward.
2. the rainwater of rain visor actively wash away to Air Filter by the application via catch basin, drainpipe, such as second Drainpipe flexural pivot is connected to the lower end of the first drainpipe, or is rotatably connected on the lower end of the first drainpipe, overhauls operation maintenance personnel Can be when the rainy day to be on duty, nozzle alignment Air Filter progress is manually actively washed away when rotating the second drainpipe, strong operability.
3. the lower end of the second drainpipe is designed to flat mouth shape, the instantaneous velocity of rainwater discharge can be improved, be conducive to improve The flush efficiency of Air Filter.
4. rain visor is herringbone or trapezoidal shape structure, it is conducive to Quick drainage, in particular, the rain cover of trapezoidal shape structure Plate can reserve reasonable installation space for unpowered blast cap.
Detailed description of the invention
