[0002] At present, high and low voltage distribution cabinets are indispensable and important equipment in the power system, and are widely used in industrial, commercial and civil buildings to distribute and control electric energy. With the continuous development of the power system, the safety and reliability of distribution cabinets have become one of the key considerations. Especially under high load operating conditions, temperature monitoring of internal components of the distribution cabinet becomes particularly important, because excessive temperature may cause electrical failures or even fire accidents, which will seriously affect the safety and stability of power supply.

[0003] In order to ensure the normal operation of high and low voltage distribution cabinets, the prior art usually uses a variety of methods to monitor the temperature inside the cabinet. Use fixed temperature sensors to be directly installed at key locations in the cabinet, or use infrared thermometers to perform manual inspections regularly. However, existing temperature monitoring methods have some shortcomings. Fixed temperature sensors can only monitor temperature changes at specific locations and cannot fully cover all components and cables inside the entire distribution cabinet. Especially when the components are densely arranged, the distance between the temperature sensor and the measured component is limited, resulting in reduced temperature measurement accuracy. Manual detection requires manual operation, which is inefficient and easy to miss certain key areas.

[0004] In view of the above-mentioned related technologies, it is necessary to propose a high and low voltage distribution cabinet with a temperature measurement structure to solve one of the above-mentioned technical problems. Summary of the invention
