Description

Technical Field

[0001] The present application relates to the technical field of high and low voltage cabinets, and in particular to a high and low voltage cabinet body with an anti-condensation function. Background Art

[0002] High and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution cabinets. Low voltage distribution cabinets are then led to distribution boards, control boxes and switch boxes for each power user. The equipment inside is a distribution device that is assembled into one by some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices to meet the design functional requirements.

[0003] At present, high and low voltage cabinets are installed either indoors or outdoors. Outdoor high and low voltage cabinets are easily affected by the external climate environment because they are exposed to the outdoors. For example, weather with large temperature differences, humid weather and marine climate can easily cause condensation in the high and low voltage cabinets, which can easily lead to serious consequences such as failure or burning of electrical components and tripping of switch equipment.

[0004] In the related art, in order to avoid condensation in the high and low voltage cabinets, a double-layer structure is generally set up in the cabinet, and the interlayer is filled with insulation material to ensure the internal temperature of the high and low voltage cabinets. However, since the power equipment in the cabinet needs to be connected to cables and the cable holes cannot be sealed, the cabinet temperature is lower than the expected temperature and moisture enters the cabinet. In addition, since the dew point temperature is not a fixed value, the high and low voltage cabinets are still at risk of condensation as the ambient temperature changes. Summary of the invention
