Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment 1 of power distribution cabinet of the invention, as shown in Figure 1, power distribution cabinet includes the cabinet for placing electrical equipment
Body 1, cabinet body 1 are surrounded by being placed in the coaming plate of the bottom plate of 1 bottom of cabinet body, 1 surrounding of cabinet body and being placed in the top cover 2 at 1 top of cabinet body, this reality
The cross section of top cover 2 in example is applied in inverted " v " structure, top cover 2 extends formation gear eaves on the outside of the coaming plate of cabinet body 1 and matches to improve this
The water-resistant performance of electric cabinet, and the steam generated in cabinet body 1 is made to rise the droplet that is condensed when touching top cover 2 along top cover 2 to cabinet
1 liang of Slideslip of body avoids droplet from instilling in cabinet body 1, but if droplet is constantly being gathered into the sliding process of 1 two sides of cabinet body
It when reaching constant weight, is still fallen in cabinet body 1 under meeting under the action of droplet gravity, therefore, in the present embodiment in cabinet body 1 also
Ventilative water lock is used to support equipped with being placed in the ventilative water lock film 3 between top cover 2 and cabinet body 1 and being arranged below ventilative water lock film 3
The support construction 4 of film 3, and be spaced and be arranged between ventilative water lock film 3 and top cover 2, what ventilative water lock film 3 can make to flow in air
Hydrone passes through, but water droplet can not be made to pass through, and avoids droplet from falling directly into cabinet body 1 from about 2 top cover backwardness, but also can
So that the steam in cabinet body 1 is normally passed through, avoids steam after encountering ventilative water lock film 3 in ventilative 3 downside of water lock film
Condensation.
It is likely to cause accident in order to avoid hoarding ponding on ventilative water lock film 3, therefore ventilative water lock film 3 is in support construction
Raise upward setting under 4 support, guides droplet to flow to 1 two sides of cabinet body when being dropped in droplet on ventilative water lock film 3, avoids
Ponding is hoarded on ventilative water lock film 3.Support construction 4 includes the support portion and fixed part to raise upward, support portion and ventilative water lock
The support cooperation of film 3, by latching the upper end of the removable coaming plate for being fixed on cabinet body 1, convenient for the power distribution cabinet is safeguarded and examined
It repairs.
It further include water outlet 5 on the cabinet body 1 of power distribution cabinet of the invention, it will be on ventilative water lock film 3 and top cover by water outlet 5
In the water discharge cabinet body 1 of 2 insides, in the present embodiment, water outlet 5 is that ventilative 3 edge of water lock film and 1 junction of cabinet body is arranged in
Outside, and water outlet 5 is arranged on the downside of gear eaves of top cover 2, water outlet 5 acts also as and top cover 2, ventilative in the present embodiment
The ventilation opening of cavity connection between water lock film 3, reduces the aperture of cabinet body 1.It certainly, in other embodiments, can also on cabinet body
Communicating passage is arranged, water is drawn into cabinet body 1.
When using the power distribution cabinet, the steam generated in cabinet body 1 is passed through from ventilative water lock film 3 when moisture is to colder
Top cover 2 when, steam liquefaction start gather droplet on the medial surface of top cover 2, when droplet accumulation to a certain extent when, droplet exists
It is flowed along the inclined two sides of top cover 2 towards 1 two sides of cabinet body under the action of gravity, continues to gather during droplet flowing, when
When droplet builds up the critical state for reaching droplet drippage, droplet fallen into from top cover on ventilative water lock film 3 gradually to
Then 1 liang of Slideslip of cabinet body flows out cabinet body 1 from water outlet 5, effectively avoids water droplet and fall on the electrical equipment in cabinet body 1
Cause the corrosion of electrical equipment and the decline of insulation performance.
