Background
The terminal box of the transformer substation is an intermediate link for connecting outdoor electrical equipment and indoor measurement and control, protection, communication and other equipment, and is generally installed beside the equipment on site. When the air is humid, particularly in rainy season, the humidity condensation water in the outdoor switch terminal box is accumulated, so that the insulation resistance of the direct current secondary circuit to the ground is easily reduced, and the insulation resistance is reduced to zero, thereby forming a direct current positive power supply or a direct current negative power supply to be grounded. If the direct current two points are grounded, a direct current fuse is fused, the protection is refused to operate or is operated by mistake, even equipment is damaged, and the safe operation of a power grid is seriously threatened. The terminal box is affected with damp to lead the terminal row screw and the connecting sheet to rust, lead the secondary terminal to have poor contact, also lead the current loop terminal to generate heat and even open a circuit, cause protection to reject operation or malfunction and cause accidents. Therefore, the humidity real-time monitoring is adopted for the outdoor terminal box, and the method has important significance for preventing accidents.
At present, the outdoor terminal box of the transformer substation is dehumidified, and a switch cabinet, a terminal box and the like are heated by adopting a manual input heating dehumidifier, so that the temperature in the box body is improved, and moisture is evaporated, thereby removing the condensation phenomenon. Therefore, timely putting in and out of the heating dehumidifier is very important for ensuring normal operation of equipment in the station. Because there is no humiture monitoring module in the outdoor terminal box, the operation and maintenance personnel generally put into the heating dehumidifier manually in 11 months every year according to the five-way regulation and the in-station maintenance plan, and withdraw from 3 months next year, in order to ensure that the heating dehumidifier always works normally in this period, the operation and maintenance personnel need to check the working condition of the dehumidifier one by one, and the operation needs to open each box body one by one for checking, so that the fault dehumidifier can not be found in time; the processing needs to be changed to unable normal operation's dehumidifier, need open the terminal box for a long time during the change, and moist air enters into the terminal box, causes the influence to the equipment of terminal box.
