Description

Technical Field

[0001] The present invention relates to the technical field of electric power devices, and in particular to a moisture-proof device for a power distribution room, which is specifically used for moisture-proofing a power distribution room of a power cabinet structure. Background Art

[0002] In the power system, the distribution room is a key link in the distribution and conversion of electric energy, and the stability of its internal environment is crucial to the safe operation of the power grid. Especially in a humid environment, excessive humidity in the distribution room will lead to a decrease in the insulation performance of electrical equipment. Therefore, moisture-proof measures in the distribution room have always been the focus of attention in the power industry. China's authorized patent (Announcement No.: CN217281660U) discloses an active moisture-proof ventilation device for the distribution room, which heats the air to remove moisture through the heating wire in the distribution room, and then prevents moisture in the distribution room. However, this device still has certain defects when used and needs to be improved;

[0003] When the moisture-proof device in the prior art is in use, the heating wire will generate heat when working, affecting the normal operation of other equipment in the distribution room. As a wearing part, it may break, age, or otherwise become damaged during long-term use and needs to be replaced, thereby increasing the difficulty and cost of maintenance. In addition, since the heating wire is arranged inside the distribution room, if the heating wire fails during operation, it may cause safety accidents such as fire, posing a threat to the distribution room and the entire power grid. Therefore, a moisture-proof device for a distribution room is proposed to overcome the above-mentioned defects.
