Abstract

The invention discloses a ring main unit dehumidification system based on wind-solar complementary self-energization. The system comprises a power supply module, a controller, a monitoring module anda dehumidification module, wherein the power supply module supplies power to the controller, the monitoring module and the dehumidification module, the monitoring module and the dehumidification module are connected with the controller, the dehumidification module comprises a semiconductor chilling plate, a fan and a radiator, the semiconductor chilling plate comprises a hot end and a cold end, the radiator is connected with the hot end, the fan improves the heat dissipation efficiency of the radiator, the monitoring module monitors the air humidity in a ring main unit, and the controller controls the semiconductor chilling plate and the input current of the fan. The ring main unit dehumidification system has the advantages that the technical problem that the performance and the service life of power equipment are reduced due to the fact that the humidity in the ring main unit is too high is solved, the potential safety hazard problem that the ring main unit catches fire is solved, andthe problem that the ring main unit dehumidification system is difficult to supply power is solved.

Description

technical field [0001] The invention relates to the technical field of electrical safety of electric power systems, in particular to a dehumidification system of a ring main unit based on self-supply of wind-solar complementary energy. Background technique [0002] Based on the environment-friendly, pollution-free, low-noise, safe and reliable product requirements and the rapid development of thermoelectric materials, a new refrigeration method based on the Peltier effect-semiconductor refrigeration has gradually attracted people's attention and attention. Research, and is gradually entering our daily life. The advantages of semiconductor refrigeration: (1) low noise; (2) easy installation; (3) can be changed according to the shape, used in some places with special needs, such as in the temperature control of miniaturized equipment or devices, Very convenient; (4) No chemical refrigerants, green and pollution-free; (5) Semiconductor refrigeration is faster and quicker in re...
