Problems solved by technology

[0003] However, during the use of the power distribution cabinet, the components in the power distribution cabinet tend to generate more heat, which makes the temperature in the power distribution cabinet rise, which in turn affects the normal use of electrical components in the power distribution cabinet and the service life of the line. At the same time, in the power distribution cabinet, due to the relatively humid air, the components are corroded, resulting in line damage or short circuit.

Abstract

The invention belongs to the technical field of power distribution cabinets and relates to a damp-proof detection and dehumidification integrated power distribution cabinet based on heat recovery. Thecabinet comprises a cabinet body; a supporting frame is arranged in cabinet body; one side of the support frame is fixedly connected with a plurality of connecting rods; the connecting rods are fixedly connected with the inner wall of the cabinet body; the supporting frame is provided with multiple sets of heat absorption pipes; boiling liquid is arranged in the heat absorption pipes; power mechanisms are arranged in the heat absorption pipes; a supporting plate is fixedly connected into the side wall of the cabinet body and located below the supporting frame; the bottom end of the supportingplate is fixedly connected with a first air bag; and the top ends of the heat absorption pipes are communicated with the first air bag. By arranging the heat absorption pipes, rapid heat absorption of components on the supporting frame can be achieved through gasification of the low-boiling-point boiling liquid, heat dissipation on the components on the supporting frame can be achieved; the heatenergy of the components is converted into mechanical energy, so that the repeated utilization of the energy is realized, and the dehumidification and drying of the cabinet body are realized.

Description

technical field [0001] The invention belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet integrated with moisture-proof detection and dehumidification based on heat recovery. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. In many occasions, they distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads, and this level of equipment should provide protection, monitoring and control for the loads. [0003] However, during the use of the power distribution cabinet, the components in the power distribution cabinet tend to generate more heat, which makes the temperature in the power distribution cabinet rise, which in turn affects the normal use of electrical components in the pow...
