Problems solved by technology

[0002] The power cabinet is a commonly used power infrastructure, which is equipped with a large number of power components, so its protection requirements are relatively high; the current power cabinet is mainly surrounded by a shell, and the shell is a layer of iron, although it can protect The internal power components play a good protective role, but the problem is that when the ambient temperature is low, especially in autumn and winter, due to the large temperature difference between the inside and outside of the power cabinet, condensation water will be generated on the inner wall of the casing, and this condensation water will feed the power supply. Electrical components inside the cabinet pose a safety hazard
[0004] The power distribution cabinet is the final equipment in the power distribution system. It is usually installed outdoors away from the power supply center for outdoor power distribution and transformation. The transformer is prone to failure during work and use, and the monitoring center cannot detect it in time. In addition, power distribution cabinets often have theft accidents, which seriously affect the normal production and power supply. The stolen components in the power distribution cabinet not only bring economic losses to the power department, but also cause a great waste of time and manpower.

Description

technical field [0001] The invention relates to an electric cabinet. Background technique [0002] The power cabinet is a commonly used power infrastructure, which is equipped with a large number of power components. The internal power components play a good protective role, but the problem is that when the ambient temperature is low, especially in autumn and winter, due to the large temperature difference between the inside and outside of the power cabinet, condensed water will be generated on the inner wall of the casing, and this condensed water will feed the power supply. The electrical components inside the cabinet pose a safety hazard. [0003] A semiconductor cooler, also called a thermoelectric cooler, is a heat pump. Its advantage is that there are no sliding parts, and it is used in some occasions where the space is limited, the reliability is high, and there is no refrigerant pollution. Utilizing the Peltier effect of semiconductor materials, when direct curren...
