AI Technical Summary

Technical Problem

In traditional high-voltage bushings, the insulating oil flows very slowly, which prevents heat from being conducted quickly, forming a thermal boundary layer that reduces heat exchange efficiency and affects insulation performance and operational stability.

Method used

The flow component includes an isolation cylinder and a drive unit. By driving the insulating medium to circulate between the capacitor core and the insulating sleeve, the thermal boundary layer is eliminated and the heat dissipation efficiency is enhanced.

Benefits of technology

It achieves directional circulation of the insulating medium, quickly absorbs the heat generated by the capacitor core, avoids thermal aging, ensures uniform temperature of the inner wall of the insulating sleeve, and improves insulation performance and operational stability.

Abstract

本发明涉及电力设备技术领域,具体涉及一种户外浸式环保气体电力变压器,包括高压套管。该高压套管包括绝缘套筒、电容芯子和流动组件。流动组件用于驱动绝缘介质在同轴设置的电容芯子与绝缘套筒之间循环流动。循环流动的绝缘介质能够迅速将电容芯子运行时产生的热量连续带走,并通过绝缘套筒壁面散发,大幅提升散热效率,有效降低电容芯子的工作温度,减缓绝缘介质热老化;同时,通过绝缘介质的循环流动打破热边界层,使轴向与周向温度分布更为均匀,避免了局部过热引发的绝缘劣化。
