背景技术Background technique
配电柜(箱)分动力配电柜(箱)和照明配电柜(箱)、计量柜(箱)，是配电系统的末级设备。配电柜是电动机控制中心的统称。配电柜使用在负荷比较分散、回路较少的场合；电动机控制中心用于负荷集中、回路较多的场合。它们把上一级配电设备某一电路的电能分配给就近的负荷。这级设备应对负荷提供保护、监视和控制。The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load.
一些配电柜需要安装在户外，而用于户外的配电柜需要保证其通风和防尘的效果，避免内部元器件的加速老化，而通风意味着需要在配电柜壳体上开设较大面积的通风口，而较大面积的通风口又导致配电柜内部器件暴露过多，无法起到防尘作用，传统的户外配电柜无法使得防尘和通风兼具，要么配电柜防尘效果好，通风效果差，导致内部热量无法散失，增加了内部元器件的加速老化，要么防尘效果差，通风效果好，这就导致灰尘能够大量的附着在内部元器件上，增加其功耗，传统的户外配电柜无法满足使用者的使用需求，为此我们设计出一种防尘通风的户外配电柜，来解决上述问题。Some power distribution cabinets need to be installed outdoors, and the power distribution cabinets used outdoors need to ensure their ventilation and dustproof effects to avoid accelerated aging of internal components, and ventilation means that it is necessary to open a large Ventilation openings with a large area, and the large-area ventilation openings cause too much exposure of the internal components of the power distribution cabinet, which cannot play a dust-proof role. Traditional outdoor power distribution cabinets cannot achieve both dust-proof and ventilation, or the power distribution cabinet is The dust effect is good, but the ventilation effect is poor, so that the internal heat cannot be dissipated, which increases the accelerated aging of internal components, or the dust-proof effect is poor, and the ventilation effect is good, which causes a large amount of dust to adhere to the internal components and increase their function. The traditional outdoor power distribution cabinet cannot meet the needs of users. Therefore, we have designed a dust-proof and ventilated outdoor power distribution cabinet to solve the above problems.

通过温度传感器检测到配电柜主体1内腔的温度超过临界值时，电动马达启动，带动转动轴9转动，调节机构向矩形进风口8的外部打开，此时扩大了配电柜主体1的通风开口，进风风机17和排风风机20同时启动，进风风机17向配电柜主体1内引入外部低温空气，排风风机20将配电柜主体1内的高温空气排出外部，使得空气循环流动，带走热量，达到通风散热的效果，弧形滤板13的设置既能保证进风量，又能对灰尘等杂物进行阻挡，提高了防尘效果，同时调节机构闭合时，挡板10完全堵住矩形进风口8，使得配电柜主体1的防尘效果进一步提升。When the temperature sensor detects that the temperature of the inner cavity of the main body 1 of the power distribution cabinet exceeds a critical value, the electric motor starts to drive the rotating shaft 9 to rotate, and the adjustment mechanism is opened to the outside of the rectangular air inlet 8. At this time, the space of the main body 1 of the power distribution cabinet is enlarged. The ventilation opening, the air intake fan 17 and the exhaust fan 20 are started at the same time, the air intake fan 17 introduces external low-temperature air into the main body 1 of the power distribution cabinet, and the exhaust fan 20 discharges the high-temperature air in the main body 1 of the power distribution cabinet to the outside, so that the air Circulating flow takes away heat to achieve the effect of ventilation and heat dissipation. The setting of the curved filter plate 13 can not only ensure the air intake, but also block dust and other sundries, which improves the dust-proof effect. At the same time, when the adjustment mechanism is closed, the baffle 10 completely blocks the rectangular air inlet 8, so that the dustproof effect of the main body 1 of the power distribution cabinet is further improved.
