Description

【Technical field】 [0001] The invention relates to the technical field of substations, in particular to an intelligent temperature regulation system and its application. 【Background technique】 [0002] With the rapid development of smart grids, more and more indoor developments have turned to outdoor closed installations in recent years. When the outdoor control cabinet is not shielded, it is affected by solar radiation and the heat dissipated by the equipment itself, so that the temperature inside the sealed cabinet may exceed the allowable range of the equipment. performance and life, which in turn leads to device failure, reduces the stability of the entire system and even causes major safety accidents. Generally, if the ambient temperature of components increases by 10°C, the failure rate of components will increase by an order of magnitude. As the main carrier of power system equipment, the cabinet is essential for safety and reliability. Therefore, how to control the...

AI Technical Summary

Problems solved by technology

However, the cabinet air conditioner is designed with a compressor. For the application of intelligent substation protection and intelligent control cabinet temperature control, there are a series of disadvantages such as large vibration, large volume, water condensation, complicated maintenance, short operating life, and no heating in winter.

Among them, the problems of large vibration and condensation may affect the working status of the electronic devices in the intelligent control cabinet and cause death, which is unacceptable for this application. Complex maintenance and short operating life will also cause high operation and maintenance costs.

[0011] 4. Summary of defects in existing temperature regulation and heat dissipation technology and technical bottlenecks in new devices using high-power semiconductor temperature regulation technology

The most effective solution to solve the heat dissipation problem of intensive high-power semiconductor temperature regulation devices is to use water-cooled heat dissipation solutions. Using water-cooled heat dissipation solutions will inevitably make the temperature regulation devices bulky and heavy, which cannot be applied to intelligent substation protection and intelligent control cabinets.

In addition, the water cooling solution needs to use a water pump for circulation. The water pump is a vibration device, which is prone to failure and is not suitable for use in this application field.
