Description
技术领域 technical field

背景技术 Background technique
变电箱(substation)就是电力系统中对电能的电压和电流进行变换、集中和分配的场所的箱体。为保证电能的质量以及设备的安全，在变电箱中还需进行电压调整、潮流（电力系统中各节点和支路中的电压、电流和功率的流向及分布）控制以及输配电线路和主要电工设备的保护，主要用于保护电力设施的。 A substation is a box in a power system where the voltage and current of electric energy are transformed, concentrated and distributed. In order to ensure the quality of electric energy and the safety of equipment, voltage adjustment, power flow (flow direction and distribution of voltage, current and power in each node and branch in the power system) control and power transmission and distribution lines and The protection of main electrical equipment is mainly used to protect power facilities.
变电箱很多时候都是被安装在户外，并且变电箱内部安装的都是电力设备。首先，变电箱由于设置于户外所以阴雨天，变电箱内部的湿度应该会很大，再者，由于里面安装的都是电力设备，如果湿度过大，势必会影响电力设备的正常工作，更有甚者会导致内部的电力设备短路，给个经济上造成很大的损失；还有一些电力设备很多都是塑料的，有的里面会用一些粘固胶，会散发出有毒气体（如甲醛等），这样电力人员刚一打开变电箱的时候，会吸入很多有毒气体，危害身体健康；所以上述的这些问题亟待解决。 The substation box is often installed outdoors, and all the electrical equipment is installed inside the substation box. First of all, the substation box is installed outdoors, so the humidity inside the substation box should be very high on cloudy and rainy days. Furthermore, since all the electrical equipment is installed inside, if the humidity is too high, it will inevitably affect the normal operation of the electrical equipment. What's more, it will cause the short circuit of the internal power equipment, which will cause a lot of economic losses; there are also some power equipment that are mostly made of plastic, and some of them will use some glue, which will emit toxic gases (such as Formaldehyde, etc.), so that when the electric power personnel just open the transformer box, they will inhale a lot of poisonous gas, which will endanger their health; so the above-mentioned problems need to be solved urgently.
