Technical Field

[0001] The utility model relates to the technical field of low - voltage compensation cabinet cooling, in particular to a cooling device for a low - voltage compensation cabinet. Background Technique

[0002] Most of the load types in the power system belong to inductive loads. Coupled with the widespread use of power electronic devices by power - using enterprises, the power factor of the power grid is relatively low. A lower power factor reduces the equipment utilization rate, increases the power supply investment, damages the voltage quality, shortens the service life of the equipment, and greatly increases the line loss. Therefore, by connecting a compensation cabinet to the power system, the inductive load can be balanced and the power factor can be improved to enhance the equipment utilization rate.

[0003] In actual work, many parameters of the capacitors in the compensation cabinet are closely related to temperature. Especially when designing precision circuits and long - life circuits, the relationship between temperature and capacitors should be fully considered.

[0004] Generally, the life of a capacitor shortens as the temperature rises, especially for electrolytic capacitors. An electrolytic capacitor with a maximum operating temperature of 85°C can generally guarantee a normal operating time of 181019 hours when operating at a temperature of 20°C; while when operating at the maximum temperature of 85°C, it can generally only guarantee a normal operating time of 2000 hours. Therefore, this situation should be noted when designing the circuit.

[0005] It can be seen that the cooling design of the compensation cabinet has a crucial impact on the service life of the capacitor.
