Description
技术领域 technical field
本发明涉及电力系统电力柜，尤其涉及一种电力柜除湿装置。 The invention relates to a power cabinet of a power system, in particular to a dehumidification device for a power cabinet.
背景技术 Background technique
电力柜是电力系统中的重要设施，其安全运行关乎各相关设备的正常运转，因此对其保护与检查也得到高度重视。若电力柜在潮湿环境下运行，对其安全带来隐患，当温度在30℃以上，空气相对湿度在80%以上时，则会引起凝露现象，凝露会造成电力设备接线端子腐蚀、降低绝缘性能而引起短路，造成不应有的停电事故和损失。 The power cabinet is an important facility in the power system, and its safe operation is related to the normal operation of all related equipment, so its protection and inspection are also highly valued. If the power cabinet operates in a humid environment, it will bring hidden dangers to its safety. When the temperature is above 30°C and the relative air humidity is above 80%, it will cause condensation, which will cause corrosion of the terminals of the power equipment and reduce the Short circuit caused by poor insulation performance, resulting in undue power outages and losses.
常用解决方案一是电力柜安装加热器，保证柜体内空气干燥，这样虽然柜内湿度降低了，但是会使柜体内温度升高，这对柜体内的仪表、元器件，导线、塑料件的可靠性和使用寿命都影响较大；方案二是在安装柜体设备的房间内加装除湿机，这样可以保证室内相对湿度控制在85%以下，使柜体内的湿度符合设备运行要求。但由于安装柜体设备房间的立体空间较大，这样就需要安装功率较大的除湿机，这样不但浪费电能而且除湿机工作时产生的噪音也较大，并且部分电力柜所处的房间并不适合安装除湿机。 The common solution is to install a heater in the power cabinet to ensure that the air in the cabinet is dry, so that although the humidity in the cabinet is reduced, the temperature in the cabinet will rise, which is reliable for the instruments, components, wires, and plastic parts in the cabinet. The performance and service life are greatly affected; the second option is to install a dehumidifier in the room where the cabinet equipment is installed, so as to ensure that the indoor relative humidity is controlled below 85%, so that the humidity in the cabinet meets the equipment operation requirements. However, due to the large three-dimensional space in the room where the cabinet equipment is installed, it is necessary to install a dehumidifier with a large power, which not only wastes electric energy but also produces a lot of noise when the dehumidifier is working, and some rooms where the power cabinets are located are not. Suitable for installing a dehumidifier.
