A control device for on-load voltage regulation and cooling of power distribution transformers
By introducing a combined structure of telescopic rods, connecting plates, and guide slots into the distribution transformer, and combining it with air-cooling and liquid-cooling systems, the problems of incomplete disconnection and insufficient heat dissipation are solved, achieving rapid disconnection and efficient heat dissipation, and ensuring the stable operation and safety of the transformer.

Abstract
本发明公开了一种用于配电变压器的有载调压与冷却控制装置，属于变压器技术领域，包括变压器，所述变压器的一侧固定连接有控制箱，所述变压器的侧边位于控制箱的一侧固定连接有机箱；本发明中，通过设置伸缩杆、连接板、导向槽、连接触头和连接轴，当变压器出现紧急状况，伸缩杆带动连接板移动，此时连接板上的限位滑块沿限位滑轨滑动，同时连接板通过连接轴牵引连接触头，连接触头借助底部滑槽在滑柱上滑动，连接轴也随之在支撑板的弧形导向槽内移动，最终连接触头在牵引和导向作用下完成180度翻转，能让连接触头快速与调压回路的对应接触端子分离，实现电路紧急切断，及时阻断故障扩大，保障变压器和电网安全。
