110kV变电站备用电源自动切换装置应用试验

摘要

The power supply mode of on-load automatic switching standby power is that the on-load automatic switching standby power works as the power supply in case of the breakdown of common power source to avoid the large-scale blackout and improve the power supply reliability and quality .Fast switchover device plays an important part in the power supply system ,whose switching success rate is essential to high-efficiency opera‐tion of the power supply system .By introducing the working principle of fast switchover mode ,the paper em‐phasizes its advantages over several other power switching modes and reaches the conclusion that the application of fast switchover device can better guarantee the normal operation of power supply system .%备用电源带负荷自动切换供电方式是：在常用电源故障失电的情况下，可以通过备用电源带负荷自动切换作为电源，避免全站（所）失电造成大面积的停电，从整体上提高供电可靠性，改善供电质量，从而确保矿井安全供电。快切装置是供电系统中的重要装置，本文介绍了快切装置的工作原理，得出了将快切装置运用于供电系统中可以更好地保证系统正常运行这一结论。
