Protection of power source in engine room equipment

探讨了如何及时监测机房电源的断相、错相、过压、欠压等情况,并在过压、欠压情况下进行稳压;在断相、错相、超出稳压范围时将电源切换到备用电源。

This article discusses how the power of the engine room to monitor the timely break phase, the wrong phase,the over-voltage,under-voltage,and so on,in the over-voltage,under-voltage situation has carried on the constant voltage;In the break phase,the wrong phase,beyond the scope of regulators will switch to a backup power source.
