| 国家标准《剩余电流动作保护装置的安装和运行》GB13955中对电气火灾监控保护装置的安装有明确要求：“电气火灾监控保护装置安装应充分考虑供电方式、供电电压、系统接地型式及保护方式。电气火灾监控保护装置的形式、额定电压、额定电流、短路分断能力、额定剩余动作电流、分断时间应满足被保护线路和电气设备的要求，在不同的系统接地形式中应正确接线”。 The National Standard GB13955 stipulates clearly the installation of electric fire monitoring and protection devices: "The installation of electric fire monitoring and protection devices should fully consider the power supply mode, power supply voltage, system grounding type and protection mode. The form, rated voltage, rated current, short-circuit breaking capacity, rated residual operating current and breaking time of the electric fire monitoring and protection device should meet the requirements of the protected line and electrical equipment, and the correct connection should be made in different grounding forms of the system. |
