Description
技术领域 technical field
本发明属于户外电气柜技术领域,尤其涉及一种符合国家IP55防护等级的户外机柜的防水防尘结构及采用该结构的户外机柜。 The invention belongs to the technical field of outdoor electrical cabinets, and in particular relates to a waterproof and dustproof structure of an outdoor cabinet conforming to the national IP55 protection level and an outdoor cabinet adopting the structure.
背景技术 Background technique
户外机柜作为智能电网中自动化设备的载体,必须提供一种近乎室内的工作环境,才能保证其自动化设备在温度、湿度、太阳辐射、风沙、雨淋等恶劣环境下正常运转和工作。中国发明专利公开文件CN1756012A公开了一种防水防尘型配电柜,该配电柜中至少其中一侧的侧板中设有上、下分体的夹层结构,下夹层内壁上设有进风口,进风口内设有轴流风机,上夹层内壁上设有排风口,上、下夹层的外壁均为设有百叶窗的防水隔板,使得各夹层构成连通百叶窗与对应进风口、排风口的风道,其中,进风口及排风口在对应夹层内壁上的位置高于对应的百叶窗位置,从而在进风口、排风口与相应百叶窗之间的风道形成高低落差,在进风口与排风口的外侧还分别设有防水防尘罩以及滤尘网。这种防水防尘型配电柜利用进风口、排风口与相应百叶窗的高低位置差及进风口、排风口外设置的防水防尘罩及滤尘网实现柜体的防水防尘,但在使用过程中,由于防水防尘罩对水蒸汽的阻挡会造成水蒸汽通过百叶窗后在夹层内积聚,积聚的水蒸汽凝结成水珠留着夹层中无法流出,其不仅会腐蚀柜体,而且夹层中存留的水重新蒸发又会加重进风口处水蒸气的含量,从而造成防水防尘罩过滤失效而致使水蒸汽进入柜体中,影响柜体内电气元件的正常运行。 As the carrier of automation equipment in the smart grid, outdoor cabinets must provide a nearly indoor working environment to ensure the normal operation and work of their automation equipment in harsh environments such as temperature, humidity, solar radiation, wind and sand, and rain. Chinese Invention Patent Publication Document CN1756012A discloses a waterproof and dustproof power distribution cabinet, in which at least one side panel of the power distribution cabinet is provided with an upper and lower sandwich structure, and the inner wall of the lower sandwich is provided with an air inlet , the air inlet is equipped with an axial flow fan, the inner wall of the upper interlayer is provided with an air outlet, and the outer walls of the upper and lower interlayers are waterproof partitions with louvers, so that each interlayer forms a connection between the louvers and the corresponding air inlet and air outlet. The air duct, wherein, the position of the air inlet and the air outlet on the inner wall of the corresponding interlayer is higher than the position of the corresponding louver, so that a height difference is formed in the air duct between the air inlet, the air outlet and the corresponding louver, and the difference between the air inlet and the corresponding louver is formed. The outside of the air outlet is also provided with a waterproof dustproof cover and a dust filter net. This kind of waterproof and dustproof power distribution cabinet uses the height difference between the air inlet, the air outlet and the corresponding louvers, and the waterproof and dustproof cover and the dust filter set outside the air inlet and the air outlet to realize the waterproof and dustproof of the cabinet body. During the process, due to the blocking of water vapor by the waterproof and dustproof cover, water vapor will accumulate in the interlayer after passing through the louvers, and the accumulated water vapor will condense into water droplets and stay in the interlayer and cannot flow out. The re-evaporation of the retained water will increase the content of water vapor at the air inlet, which will cause the filter failure of the waterproof dustproof cover and cause water vapor to enter the cabinet, affecting the normal operation of the electrical components in the cabinet.

附图说明 Description of drawings
图1为本发明户外机柜具体实施例的局部结构示意图; Fig. 1 is the partial structure schematic diagram of the specific embodiment of outdoor cabinet of the present invention;
图2为图1中的A部放大图。 Fig. 2 is an enlarged view of part A in Fig. 1 .
具体实施方式 Detailed ways
本发明的户外机柜的具体实施例如图1、图2所示,该户外机柜至少在其一侧侧壁100上由底部至顶部竖向间隔的设有三个用于供机柜散热的通风装置,其中,位于顶部的通风装置为用于将机柜内的高温排出的排风装置101,中部及下部的两通风装置均为向机柜内供风的进风装置102,进风装置102与排风装置101均具有开设有机柜侧壁100上的通风口及罩设于对应通风口外的百叶窗,其中,位于进风装置102内的通风口为进风口,位于排风装置101内的通风口为排风口,在排风装置101及进风装置102中均设有用于防止水蒸汽及灰尘等杂质通过先相应通风口进入柜体内部的防尘防水结构。
The specific embodiment of the outdoor cabinet of the present invention is shown in Fig. 1 and Fig. 2. At least on one
本实施例以进风装置102中的防尘防水结构为例,如图2所示,本实施例中,该进风装置102是在机柜侧壁100上挖设有内凹的凹槽1,在位于凹槽1内的槽底壁上部开设有进风口2,在凹槽1的槽口罩设有与机柜侧壁100平齐的百叶窗3,百叶窗3下部开设有上下排布的开口,进风口2与百叶窗3之间留有间隙,凹槽1四周的槽壁围成连通百叶窗3与进风口2的风道4,百叶窗3的各开口不高于进风口2,其中,百叶窗3最底层的开口的下口沿与风道4的下壁面5齐平,从而可以将风道4中凝结的水及时排出。在百叶窗5的开口内侧还罩设有纱网(图中未视出),在进风口2的外侧罩设有过滤棉6。为加强机柜内部的通风,提高散热效率,其在进风口的内侧还固定有轴流风机7。
In this embodiment, the dust-proof and waterproof structure in the air inlet device 102 is taken as an example. As shown in FIG. An
排风装置101与进风装置102的结构基本相同,两者之间的区别仅在于排风装置101的排风口内未安装轴流风机。
The structure of the
机柜在户外工作时,外界含有水蒸汽、粉尘等杂质的空气通过百叶窗3进入到风道4中,颗粒较大的灰尘被百叶窗3内侧设置的纱网阻挡,颗粒较小的灰尘和水蒸汽被进风口2外设置的过滤棉6阻挡,从而仅让干燥、洁净的空气进入到柜体内,水蒸汽在风道4中凝结后形成的水珠流到风道4的下壁面5上通过百叶窗3最底层开口流出,避免水在风道4中存留。当机柜中的温度达到一定限度后,进风装置102中的轴流风机7开始工作,空气从柜体中、下部的进风装置102进入柜体内带动电子设备工作过程中产生的热量流动上升,最后由最上方的排气装置101中的排风口和百叶窗排出柜体,形成空气循环,减少因热量局部集中而造成对元器件的损坏,从而延长户外机柜的使用寿命。
When the cabinet is working outdoors, outside air containing impurities such as water vapor and dust enters the
