A ring main unit dehumidification system with self-adaptive wind and solar complementary power supply

Abstract

The invention discloses a dehumidification system for a ring network cabinet with environment-adaptive wind-solar complementary power supply, which includes a power supply device, an electric energy conversion device, a charging and discharging management system, an energy storage device, and a dehumidification device. The energy storage device is electrically connected, the energy storage device is electrically connected to the dehumidification device through the electric energy conversion device, and the charging and discharging management system controls the action of the electric energy converter to ensure the safety of charging and discharging the energy storage device. The power supply device includes a wind power generator set, a photovoltaic power generation device, a regulating device, a tower pole and a controller. The controller controls the adjusting device to perform the adjusting action. The device has played a positive role in improving the power supply efficiency of the wind-solar hybrid generator set and the fire safety in the ring network cabinet.

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...
