<p>A general load control type combined fire protection self-generator capable of improving profitability is provided to safely supply a power load for fire by including an apparatus opens a disconnect switch for general load before operating a main power source disconnect switch by a load. A general load control type combined fire protection self-generator(Ge) has a main power disconnect switch(SM). The main power disconnect switch is automatically disconnected by over current of a main power line. A bottom of the main power disconnection switch is connected to a power disconnection switch(SN) for general load and a power disconnection switch(SF) for fire. The general load control type combined fire protection self-generator comprises a current transformer(CT) and a programmable logic controller(PLC). The current transformer is installed in the main power line, and senses a current variance. The programmable logic controller is connected to the current transformer and the power disconnection switch for general load.</p> |
