Whether the fire pump should be equipped with overload protection

Fire pump is an important equipment for fire fighting and rescue. According to our habitual thinking, all important equipment should be equipped with overload protection. However, according to article 8.6.3.5 and article 1 0.2.2.4 (3) of the civil regulation, "for distribution lines whose sudden power failure will lead to greater losses than those caused by over-load, over-load protective appliances (such as power supply lines of fire pumps) that cut off the circuit shall not be installed, but over-load alarm appliances shall be installed. According to this regulation, the fire pump should not be equipped with overload protection cut-off device. This is mainly in view of the fire, the need to ensure the fire water, because the pump overload may cause line, equipment loss compared with the fire loss is negligible. But in engineering practice, and even in some construction standard atlas, including college textbooks introduced in fire pump electrical diagram, fire pump overload protection circuit is added to the cut off the electrical appliances, such as atlas of building electric installation engineering JD13 18 pages 3 'high-rise building fire system full voltage start the fire pump control device (2) ".
