The energy-saving outdoor terminal box dehumidifying and cooling device has the beneficial effects of being green, energy-saving and environment-friendly since the device is powered through the power generated by the solar cell panel, being capable of solving the high temperature problem completely through the additionally arranged refrigerating device, having field alarming and dispatching real-time monitoring functions, improving the intelligent degree of a terminal box, enhancing the visible and controllable properties of temperature and humidity inside the outdoor terminal box, reducing insulation deterioration and short circuit failures caused by moisture and high temperature, and being of great significance to prevent electrical accidents.

Description

(1) Technical field [0001] The invention belongs to the technical field of power grids, and in particular relates to an energy-saving outdoor terminal box dehumidification and cooling device. (2) Background technology [0002] The outdoor terminal box of the substation is an intermediate link between outdoor electrical equipment and indoor measurement and control, protection, communication and other equipment, and is generally installed next to the equipment. When the air is humid, especially in the rainy season, the moisture and condensation in the outdoor switch terminal box will not only cause the box to be easily corroded, but also easily lead to a decrease in the insulation resistance of the DC secondary circuit to the ground. In severe cases, the insulation resistance will drop to zero. Thereby forming a direct current positive power supply or negative power supply grounding. If the two points of DC are grounded, the DC fuse will be blown, the protection will refu...
