摘要
在分析异步电动机、消防水泵、消防风机特性基础上,探讨消防水泵、消防风机过载保护和堵转保护,以及配电线路过负荷保护,提出消防配电应考虑消防设备及配电系统的特性,在火灾时尽量让消防设备在安全、可靠的配电系统下坚持工作,以保障人身和财产安全。
Based on an analysis on the characteristics of asynchronous motor,fire pump and fire fan,the overload protection and locked rotor protection for fire pump and fire fan as well as the circuit overload protection are discussed,proposing that the features of relevant fire safety equipment and the distribution system shall be considered,so as to ensure the normal operation of fire safety equipment in a safe and reliable distribution system in case of fire to guarantee the personal and property safety.
