Description of drawings
Fig. 1 is the circuit block diagram of the utility model shield door supply power mode.
Below in conjunction with accompanying drawing, to the nearly step detailed description of the utility model.
Embodiment
Can see essential structure of the present utility model clearly by Fig. 1: mainly be respectively 1 and 6,2 by two groups of dual power supply switching boxes and form for control loop UPS, two groups of rectification modules 7 and 8, the intelligent power distribution unit 5 that drives intelligent power distribution unit 4, loop and control loop for driving loop UPS, 3.Wherein: first group of electrical source exchange case draws and connects the two-way civil power and drive loop UPS and control loop powered ups to shield door; Second group of electrical source exchange case is the control loop power supply; Driving loop and control loop intelligent power distribution unit is used for distributing electric energy to each load; The UPS monitoring system is connected and monitors with above-mentioned subsystems.The two-way input of described the second dual power supply switching box is from different UPS power supplies, and first via primary input is from control loop UPS rectification output, and the commutating phase in the second pass self-driven loop UPS three-phase alternating current output is exported.Control loop adopts 1+1 parallel redundancy mode to power.When control loop UPS broke down, control loop can obtain electric energy from driving loop UPS.In addition, two groups of intelligent power distribution unit are provided with by-pass switch, can manually realize the Third Road power supply when PLC controller or on-load switch tripping operation.Screen door also comprises for Real-Time Monitoring UPS monitoring unit, and the UPS monitoring system can monitor and diagnose above-mentioned all power supply units, and the UPS monitoring system comprises communication network, can station comprehensive monitoring system communication.The power distribution to all machines can be completed in driving intelligent power distribution unit, loop, guarantees that each machine can work.The power distribution of each control units such as PSA, PSL, DCU can be completed in control loop intelligent power distribution unit, guarantees the normal operation of each control unit.In order to guarantee to drive the high reliability in loop, the dual power supply switching box output is electrically connected to two and drives loop UPS main frame.
The shield door electric power system belongs to a stage load, should adopt a stage load power supply, draw by electric substation the two-way independence civil power that connects and be connected to first group of dual power supply switching box, the two-way power supply of built-in PC level double power supply automatic switching switch is standby each other, can be automatically and manual switchover.Controller is that external is installed, break-before-make in the electrical source exchange process, and can haul oneself willingly into runback.Second group of dual power supply switching box function class seemingly.
Under normal mode of operation, drive loop UPS and control loop UPS and accept the electric energy that first group of dual power supply switching box exported, then drive loop UPS energy supply to driving intelligent power distribution unit, after the rectification of control loop UPS output simultaneously, energy supply is to control intelligent power distribution unit.UPS inside is comprised of rectification/charger, inverter, batteries and static bypass switch.Rectifier/charger converts alternating current to suitable direct current, and this direct current accumulators group floating charge provides DC power supply to inverter simultaneously, and inverter converts it to the alternating current of regulation parameter again.In the situation that the two-way civil power breaks down and can not power, the UPS batteries can provide enough electric energy, and its power reguirements satisfies the requirement of screen door regulation.Rectifier provides direct current to batteries and inverter behind the city power recovery.When inverter or rectifier break down, static bypass switch work, the control loop load transfer does not interrupt power supply to bypass.After Failure elimination, system rotates back into load on UPS again, thereby does not affect the load normal operation.
