The accompanying drawing explanation
Fig. 1 is serial schematic diagram of power supply of emergency power supply system of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the emergency power supply system that nuclear power station passive system provided by the present invention is relevant is divided into A, B series according to supply load.A herein, B series are the A described in nuclear power station owner technique, B series, refer to whole nuclear power station Redundancy Design to load from the AC power to the DC power supply, B series is the redundancy of A series fully, and A series breaks down, and does not affect B series and completes nuclear safety function.Two complete equipments are carried out safety function, and a set of fault is another set of unaffected, continue to carry out function.Therefore emergency power supply system of the present invention also is provided with two covers, with A, the B series matching of whole nuclear power station.
Each series consists of direct current component and AC portion, and direct current component consists of two chargers 1,2 and a group storage battery 3 and one group of DC power distribution cabinet 4, and AC portion consists of inverter 5 and voltage regulating transformer 6, static switch 7 and AC power distribution cabinet/AC distribution panel 8.Two chargers 1,2 of direct current component are connected with DC power distribution cabinet 4 respectively with a group storage battery 3, and DC power distribution cabinet 4 is connected with the inverter 5 of AC portion, and inverter 5 is connected with AC power distribution cabinet/AC distribution panel 8 by static switch 7 respectively with voltage regulating transformer 6.A charger 1 in two chargers is connected with emergent 380V AC power 10 in nuclear power station, and another charger 2 is connected with the 380V AC power 11 that SBO diesel engine (the additional diesel engine started during station blackout) is powered.
The emergency service method that the present invention is directed to the said system design is as follows:
Under normal circumstances, a charger is by the Power supply of the 380V with diesel engine in nuclear power station, and charger is load carrying is battery charging simultaneously.
