[0002] In recent years, with the increasing shortage of urban land resources, the space for equipment installation has become extremely limited. Therefore, users' demand for high-voltage capacitor compensation devices has gradually shifted to miniaturization, compactness and integration to meet the needs of efficient operation and efficient use of space in modern power systems. Cabinet-type high-voltage capacitor compensation devices have emerged and have won the favor of the market with their unique advantages. For example, CN218498828U provides a compact and refined reactive compensation device that solves the problems of diverse layout of components inside the cabinet, complex wiring methods, large differences in device sizes, and difficulty in modularization. This structure adopts a combination of standard modules, which can quickly complete the internal layout design of device cabinets with different capacities and capacitor quantities. The standard module size is serialized and suitable for products with various capacity configurations, realizing mass production of standard sizes, thereby changing the previous production mode of customized orders and greatly improving production efficiency. However, although the cabinet-type device provided by CN218498828U has the advantages of small footprint and simple construction, it encloses the capacitor set inside the cabinet, and the ventilation and heat dissipation effect is poor. Especially in places with high ambient temperature, the temperature rise of the capacitor in the cabinet may be close to the standard limit, which will directly affect the service life of the capacitor.

[0003] Therefore, how to optimize the heat dissipation performance and ensure the reliable operation of the capacitor while maintaining miniaturization, compactness and integrated design is an urgent problem to be solved in the field of high-voltage capacitor compensation device design.
