Description

technical field [0001] The invention relates to the technical field of power equipment maintenance, in particular to a dehumidification system for a ring main unit with self-adaptive wind-solar complementary power supply. Background technique [0002] The high-voltage ring network cabinet currently faces two main problems, one type of internal dehumidification, the fire safety of the ring network cabinet and the power supply problem of the dehumidification system of the ring network cabinet, and the internal dehumidification problem. Domestic scientific research institutions and enterprises have developed high-voltage cabinets. Electronic dehumidification system, but there are also problems such as unstable power supply: There are DC electronic dehumidifiers that use batteries, but the batteries need to be replaced frequently, and long-term stable power supply cannot be guaranteed; The mains power is used as the power supply of the 220V AC dehumidifier, but this increases th...
