Cabinet dehumidifying device and method and cabinet monitoring system and method thereof

Abstract

The invention discloses a cabinet dehumidifying device which comprises a control module, a dehumidifying module and a heating module. The dehumidifying module and the heating module are both arranged in a cabinet. The control module is used for analyzing and judging received signals, starting or removing the dehumidifying module and the heating module, judging a fault type and feeding back information in time. The dehumidifying module is used for condensing and collecting moisture in air in the cabinet and discharging the moisture out of the cabinet. The heating module is used for heating the air in the cabinet. The invention further discloses a cabinet dehumidifying method and a monitoring system and monitoring method thereof. According to the technical scheme, cold end frosting of refrigeration fins is effectively prevented, the moisture is discharged out of the cabinet in time, absolute humidity in the cabinet is reduced, fault information is fed back in time and maintained, therefore normal operation of the dehumidifying device is guaranteed, and the effect of thorough dehumidifying is achieved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a cabinet dehumidification device and method, and a cabinet monitoring system and method thereof. Background technique [0002] In recent years, electrical accidents have occurred frequently due to the moisture condensation of the equipment in the electrical cabinet. With the development of science and technology, sealed electrical cabinets have become more and more common, and the equipment in the cabinet has become more and more compact. The requirements for the tide drive device are getting higher and higher. In order to ensure the normal operation of the electrical equipment in the electrical cabinet, there are strict requirements on the humidity of the air in the cabinet. When the relative humidity in the air reaches a certain value, it will easily cause the equipment to condense. Lead to the occurrence of dangerous conditions such as creepage and short circuit, ther...
