Based on a control method for high power load equipment emergency service control system, during its normal power supply:
Powering mode selector switch is placed in "off" position, and normal power supply busbar is communicated with by normal power supply main fuse and normal power supply block system relay, carries out normal power supply to high power load equipment;
When adopting emergent busbar to power:
Powering mode selector switch is placed in " connection " position, emergency service is communicated with the control coil of relay for electrically connecting, the actuating of relay, emergency service busbar is communicated with the connection of relay by emergency service main fuse and emergency service, carries out emergency service to high power load equipment;
The control coil of normal power supply block system relay is for electrically connecting, and the actuating of relay, cuts off normal power supply circuit.
Advantage of the present invention is: the present invention is by a kind of design of high power load equipment emergency service control mode; achieve the isolation of emergency service circuit and normal power supply circuit; fundamentally isolate the charge and discharge process of electric capacity self in high-power power supply unit to emergent power supply quality and the impact connecting normal all the other loads of busbar; reduce failure rate, add the fail safe of system.
