Redundancy design principle of power system in high-level biosafety laboratories

 Compares and analyses the domestic and foreign standards on requirements of redundancy design principle such as cold and heat source, gas supply and power supply system employed in high-level biosafety laboratory. Presents the international redundancy design principles of power systems. According to the concrete implementation forms of redundancy design of power system in the existing high-level biosafety laboratories in China, proposes some redundancy design suggestions.
