Dehumidifying system, and control system and control method thereof

Abstract

The embodiment of the invention discloses a dehumidifying system, comprising a dehumidifier which is internally provided with a humidity sensor, an exhausting system, a heating system, a condensation system and a circulating pipeline. An adaptive control system controls the on and off of the exhausting system, the heating system, and the condensation system according to the magnitude relation between a humidity value detected by the humidity sensor and a preset threshold. A dehumidifying control system is used for collecting the control information from the adaptive control system received by the dehumidifier, and determining the operation state of the dehumidifier, thereby providing a reference for the adaptive control system to adjust parameters of the control information sent to the dehumidifier. The adaptive control system controls the dehumidifier to enter a corresponding work state according to detected humidity values; based on the operation state information of a determined dehumidifier, the adaptive control system can timely obtain whether the dehumidifier realizes preset dehumidifying effects; if the dehumidifier does not realize preset dehumidifying effects, the adaptive control system can adjust the parameters of the control information, and control the dehumidifier to enter a corresponding work state, thereby realizing optimized dehumidifying effects.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a dehumidification system and its control system and control method. Background technique [0002] In the power system, some power equipment, especially the equipment that realizes various control and execution functions, has higher and higher requirements for the environment. In order to ensure the normal operation and reliability of the service life of these equipment, the equipment needs to be strictly Control in a dry work environment. [0003] Common electrical equipment that needs to work in a dry environment, such as power high-voltage cabinets, outdoor / indoor switches, knife control boxes and power boxes, etc., are equipped with some electronic components that need to work in a dry environment. Especially in the control box of the substation equipment in the power equipment, the electronic components in it are easy to get wet when the weather changes, which may cause th...

AI Technical Summary

Problems solved by technology

Especially in the control box of the substation equipment in the power equipment, the electronic components in it are easy to get wet when the weather changes, which may cause the rotating parts of the electrical equipment to fail when performing work, which may lead to a decrease in insulation resistance and cause electrical breakdown. Poor contact or short circuit of the secondary terminals may cause equipment refusal or tampering, which greatly increases the potential safety hazard of the substation equipment and seriously affects the safe operation of the substation equipment.

[0004] The dehumidifiers in the existing power equipment cannot achieve the optimal dehumidification effect. The inspectors need to detect the dryness of the electric equipment on site and control the dehumidifier accordingly. Since the inspectors cannot be on-site for inspection in real time, they cannot know the power in time. The dry condition of the equipment, which makes the power equipment still have potential safety hazards
