All-digital intelligent temperature and humidity control dehumidification system

Abstract

An all-digital intelligent temperature and humidity control dehumidification system is arranged in a housing of a cabinet of an electrical device and comprises a heater, a dehumidifier, a controller which is connected with and control the heater and the dehumidifier, and a temperature and humidity sensor communicated with the controller. According to the all-digital intelligent temperature and humidity control dehumidification system, the temperature and humidity sensor is used for continuously measuring the change of relative humidity and temperature in the cabinet, the controller is used for automatically controlling the start and stop of the dehumidifier and the heater, and the heater is started for working in matching when the temperature is low, so that the system can work at a wide temperature range stably, the air humidity in the cabinet can be ensured to be maintained at a reasonable range, the humidity in the cabinet of the electrical device can be effectively reduced, the condensation in the cabinet of the electrical device can be effectively eliminated, all kinds of accidents caused by damp can be prevented, and the energy efficiency is obtained; meanwhile, the dehumidifier serves as the core, the heater and the ventilation design are used for auxiliary dehumidification, and self-test and protection functions are arranged, so that the safety of the operation of the device can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of dehumidification of power equipment, in particular to an all-digital intelligent temperature and humidity control dehumidification system and a dehumidification method. Background technique [0002] In a large number of operating power transmission and transformation equipment, the insulation distance of sealed boxes such as switchgears, box transformers, central control cabinets, and outdoor terminal boxes is tight. Tripping, or even burning equipment, causing large-scale power outages, the consequences will be very serious. Especially the internal insulation level of electrical equipment in high-humidity areas puts forward higher requirements for moisture-proof and anti-condensation in the cabinet. Condensation is the biggest problem causing accidents in high and low voltage cabinets, central cabinets, terminal boxes, etc. For example, the seven-day heavy fog in Harbin in 2000 caused a power outage acr...

Problems solved by technology

[0007] ⒊Semiconductor dehumidification: Semiconductor dehumidification is an application of semiconductor refrigeration chips in the field of dehumidification, but this application is restricted by its own conditions. Under high or low ambient conditions, the dehumidification effect is poor or even invalid, and its dehumidification The amount is small, because the occasion that needs to be dehumidified is not sealed, when the humidity of the external environment is very high, the dehumidification of the semiconductor is a bit powerless at this time
