POWER CONTROL SYSTEM SWITCHBOARD AND AUXILIARY CONTROLLER FOR RESERVED THE POWER OF THE FIRE-FIGHTING AND THE METHOD OF OPERATION

摘要

The present invention relates to reserved firefighting power control system switchboard and an auxiliary control device. A measurement device or a control device detects a changed power value of emergency power including a firefighting load and an emergency load classified by purpose. In a protective CPU, a generator control panel, or an auxiliary control device, the operation of a reserved firefighting power operation device and a display device thereof is conducted by the switchboard and the auxiliary control device with a fixed set value automatically connected and stored according to the rated output capacity setting of an emergency generator in advance and a temporary set value stored by any manual input. In case of fire, the emergency power is continuously supplied to stably have firefighting safety. A test drive performance test can be performed in a field in a non-fire situation without overload conditions. An operation capacity usage rate is increased in the non-fire situation by the connection operation which determines fire or not with fire signals. As the operation of an emergency main power circuit breaker and an emergency circuit breaker at the lower end thereof, the reserved firefighting power operation integrally or successively controls the emergency circuit breaker before the operation of the emergency main power circuit breaker in any case by composing a protection cooperation relation. Therefore, the firefighting safety is secured with the continuous supply of the emergency power in case of fire by not cutting off the main power circuit breaker and a firefighting circuit breaker before the emergency circuit breaker is cut off. The safety and management efficiency of power facilities are increased by easily checking the battery performance state at the switch board frequently.
