The fire inspection power supply device that another group of power supply is powered is automatically switched under condition.
In order to realize the purpose, the utility model is adopted the following technical scheme that：
A kind of fire inspection power supply device, including, main power source, stand-by power supply, main power source and stand-by power supply are respectively by the
One current supply circuit and the second current supply circuit are connected with fire inspection amplifier, control second is connected with first current supply circuit and is powered
The control device of loop break-make, when the first current supply circuit is powered off, it is fire that the control device controls the second current supply circuit to connect
Inspection amplifier is powered.
Further, the control device is relay, and the relay is connected on the first current supply circuit, relay it is normal
Closed contact is connected on the second current supply circuit, and in relay power, cuts off the second current supply circuit.
Further, the relay is the first relay KM1 being connected in parallel on the first current supply circuit, the fire inspection amplifier
It is connected with the first current supply circuit by the normally opened contact of the first relay KM1；Second is also associated with second current supply circuit
Relay KM2, the second relay KM2 are connected by the normally-closed contact of the first relay KM1 with the second current supply circuit, the fire inspection
Amplifier is connected by the normally opened contact of the second relay KM2 with the second current supply circuit.
Further, it is respectively equipped with opening manually for control loop break-make on first current supply circuit and the second current supply circuit
Close.
Further, the main power source and stand-by power supply are also connected with a supply monitor respectively.
Further, the main power source is ups power, and the stand-by power supply is APS power supplys.
After using technical scheme described in the utility model, following beneficial effect is brought：
Main power source of the present utility model can automatically switch to stand-by power supply and power when powering off, and not only increase system power supply
Reliability, it is ensured that system will not cause unit tripping because power supply loses, and by increasing supply monitor, accomplish
To two groups of monitoring of power supply, operations staff is found the problem of system power supply in time, and notify to examine in the very first time
Repair personnel's treatment, it is to avoid threaten the safe and stable operation of unit because of pinpointing the problems not in time.
Brief description of the drawings
Fig. 1：System block diagram of the present utility model；
Fig. 2：Power supply the principle figure of the present utility model；
