Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of waterproof and the good power distribution cabinet of radiating effect.
For achieving the above object, the utility model provides following technical scheme: a kind of power distribution cabinet, comprise cabinet and cabinet door, described cabinet sidewall is provided with transom, be connected with side shield in described cabinet, between side shield and cabinet sidewall, form ventilation slot, bottom described side shield, be connected with ventilating board, described ventilating board offers ventilation hole, between described ventilating board and cabinet diapire, is formed with gap.
Preferably, ventilation slot from top to bottom narrows gradually, and the rear wall of described side shield side and cabinet is affixed, and opposite side abuts with cabinet door.
Preferably, the roof of cabinet is provided with fresh air inlet, and described fresh air inlet place is connected with induced draft plate, and the inner side of the roof of described cabinet is provided with overhead gage, and the two ends of described overhead gage are all extended side shield and arrived ventilation slot place.
Preferably, overhead gage and side shield are all connected with flanging, and described flanging is positioned near cabinet door side.
Preferably, the diapire of cabinet is provided with apopore.
Compared with prior art the utility model has following advantage: form ventilation slot between side shield and cabinet sidewall, ventilating board is connected with bottom side shield, ventilating board offers ventilation hole, gap is formed between ventilating board and cabinet diapire, when there being wind to be blown into transom, wind can enter the inside of power distribution cabinet from the top of side shield, or enters from ventilation hole, take away the heat in power distribution cabinet, play good radiating effect; When rainy, block rainwater when rainwater enters transom by side shield, rainwater can slide into bottom along side shield, and rainwater can flow out from the gap of cabinet door and cabinet.

Embodiment
With reference to accompanying drawing, the utility model power distribution cabinet embodiment is described further.
A kind of power distribution cabinet, comprise cabinet 1 and cabinet door 2, cabinet 1 sidewall is provided with transom 3, and transom 3 can be connected with weather shield 31, thus Open Side Down to make transom 3, ensure that rainwater is not easy to enter the inside of power distribution cabinet so to a certain extent; If do not arrange weather shield 31, wind is just more prone to enter from transom 3, advantageously in the heat radiation of power distribution cabinet inside.Side shield 4 is connected with in cabinet 1, ventilation slot is formed between side shield 4 and cabinet 1 sidewall, ventilation slot has been communicated with the inside of power distribution cabinet, can be used for air ventilation, ventilating board 5 is connected with bottom side shield 4, transformer be arranged on ventilating board 5 top and between two side shields 4, ventilating board 5 offers ventilation hole 51, gap is formed between ventilating board 5 and cabinet 1 diapire, when there being wind to be blown into transom 3, wind can enter the inside of power distribution cabinet from the top of side shield 4, or arrival gap enters from ventilation hole 51; Wind enters from the side of power distribution cabinet, take away power distribution cabinet inside to blow out from opposite side compared with the air of upside heat, the air on the downside of it supplements, and wind just enters in power distribution cabinet and supplements from ventilation hole 51 afterwards, thus the heat taken away in power distribution cabinet, play good radiating effect; When rainy, block rainwater when rainwater enters transom 3 by side shield 4, rainwater can slide into bottom along side shield 4, and rainwater also can not move upward and enter power distribution cabinet inside from ventilation hole 51, makes power distribution cabinet internal unit be not easy short circuit or aging.
Ventilation slot from top to bottom narrows gradually, like this be arranged so that the more wind be blown into from transom 3 enters the inside of power distribution cabinet from the top of side shield 4, be more prone to the air taking away power distribution cabinet upper inside heat, such setting more easily makes air form circulation, the heat in power distribution cabinet can be taken away more rapidly and thoroughly, the diapire of cabinet 1 can be provided with apopore 11 simultaneously, apopore 11 can be used for draining on rainy day, when air circulation, can be used for air intake or air-out, further facilitate heat radiation, and improve radiating efficiency.The rear wall of side shield 4 side and cabinet 1 is affixed, opposite side abuts with cabinet door 2, such setting prevents rainwater from entering power distribution cabinet inside from both sides to a certain extent, also stop that wind enters power distribution cabinet inside from both sides, ensure the smooth circulation of air, reduce the generation of sinuous flow, thus ensure to dispel the heat fast, improve radiating efficiency.
The roof of cabinet 1 is provided with fresh air inlet 6, fresh air inlet 6 place is connected with induced draft plate 61, like this when there being wind, induced draft plate 61 can guide in wind direction power distribution cabinet, thus imports in power distribution cabinet by wind, strengthens intake, thus the air circulation in increasing power distribution cabinet, further reinforcement radiating effect, the inner side of the roof of cabinet 1 is provided with overhead gage 7, the top of all outstanding side shield 4 in two ends of overhead gage 7.Like this when to rainy day, ensure that rainwater can not drip on transformer, rainwater can flow to side shield 4 from overhead gage 7 two ends, thus flows to bottom by rainwater discharge, plays the effect of waterproof.
General overhead gage 7 and side shield 4 abut with cabinet door 2, can prevent into water so to a certain extent, as preferably, overhead gage 7 and side shield 4 are all connected with flanging 8, flanging 8 is positioned near cabinet door 2 side, blocked the rainwater arrived on overhead gage 7 and side shield 4 like this by flanging 8, prevent rainwater from the gap of cabinet door 2 infiltrate.
All can arrange screen pack in ventilation hole and between side shield and overhead gage, screen pack is coated with drier, wind can sponge steam wherein through screen pack, ensures the dry and comfortable of power distribution cabinet inside, makes equipment be not easy aging or short circuit further.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
