摘要: 户外箱式电容器在雨雪、寒冷或高温环境下,传统的左右通风散热形式往往会出现温度不均、进出风口漏水、灰尘堵塞等问题。根据箱式电容器的内部配置和散热需求,设计一种侧进风、顶出风的散热方案。通过优化进出风口、风机数量和位置,在进风口设置导风板,在环境温度55℃情况下,内部元器件满足散热要求,同时箱体满足IP54的结构防护要求。该方案实际运行效果良好,为箱式电容器的散热设计提供参考。

Abstract: Outdoor box capacitors often encounter problems such as uneven temperature, water leakage at the inlet and outlet, and dust blockage in traditional left and right ventilation and heat dissipation methods in rainy, snowy, cold, or high-temperature environments. A heat dissipation scheme for side inlet and top outlet air is design based on the internal configuration and heat dissipation requirements of box capacitors. By optimizing the number and position of air inlet and outlet, fans and installing guide plates at the air inlet, the internal components meet the heat dissipation requirements at an ambient temperature of 55 ℃, and the box body meets the structural protection requirements of IP54. The actual operation effect of this scheme is good, providing a reference for the heat dissipation design of box capacitors.

Key words: box heat dissipation design, air cooling, protection, filter
