    摘 要:为了解决现有变电站强排水系统无法自动检测排水效果的问题,提出了一种集水井微机控制强排水系统及排水效果自动检测方法。该系统通过采集集水井水位、强排水系统出水口水流速度及水泵电流判断集水井排水效果,实现了水泵自动排水控制、排水效果自动检测、异常自动报警功能。该系统代替了人工定期检查,并在一座 220 kV 变电站中得到试点应用,应用结果表明,其可以自动检测排水效果,提高了变电站运行的安全性,降低了变电站管理成本,提高了工作效率。

    Abstract: An existing problem of the substation forced drainage system is that the system could not automatically detect the drainage effect.This research proposed a microcomputer in the water-collecting well and a solution for automatic detection. The system could determine the drainage effect of the water-collecting well by collecting the water level of the water-collecting well, the water flow speed of the outlet of the forced drainage system, and the working current of the pump. It realized the function of the water pump auto-control of drainage, automatic detection of drainage effect, and automatic alarm of abnormality. This system replaced the manual inspection, and it has been applied in a 220 kV substation. The result shows that this system can automatically detect the drainage effect, improve the safety of substation operation,reduce the cost of substation management, and improve work efficiency.
    Key words: substation; water-collecting well; water pump; forced drainage system; drainage effect
