Emergency Power System Scheme
Overview
- Article 6.2.1 of GB 51348-2019 "Civil Building Electrical Design Standard (Description of Provisions)" stipulates as follows: Emergency Power Supply (Emergency Power Supply), referred to as EPS, is a power supply equipment composed of power converter, energy storage device (battery) and transfer switch (electronic or mechanical). When the AC input power is normal, the AC input power is directly output through the transfer switch.
- The AC input power simultaneously charges the battery pack through the converter. In case of interruption (such as power interruption, voltage does not meet the power supply requirements), EPS uses the energy storage discharge of the battery pack to pass through the inverter transformation, and automatically switches to the emergency state to supply power to the load through the transfer switch.
