Description
Technical field
The utility model relates to a kind of power supply circuits, the power supply circuits during the equal fault of particularly a kind of railway intelligent power supply panel power supply modular converter.
Background technology
Using I, II road power supply circuits in the railway intelligent power supply panel at present is two modular converters, and two modular converter power supplies all can automatic, manual switch.Work as I, during the equal fault of II road power supply modular converter, the whole not output of power supply panel, the station power consumption equipment can not be worked because of short of electricity, directly influence train operation, reduce conevying efficiency, added emergency supply circuit afterwards, but from finding that fault is to practical operation, can not be worked because of short of electricity in the station, if can not find in time that fault still can influence train operation, and emergency service has the operating sequence requirement, if the operating sequence mistake can cause power supply panel phenomenon on fire, if misoperation emergency supply circuit under the situation of normal power supply also can cause unnecessary fault to power supply panel simultaneously.
Fig. 1 dotted line is existing power supply screen I, the II road change-over circuit of automatically, manually powering, and as shown in the figure, I road three-phase input power supply is input to modular converter I through S1QF, outputs to terminal A, B, C respectively through modular converter I delivery outlet again; II road three-phase input power supply is input to modular converter II through circuit breaker S2QF, output to terminal A, B, C respectively through modular converter II delivery outlet again, finish the interlocking interlock function by modular converter I and modular converter II internal circuit, when I road three-phase input power supply has a power failure or modular converter I fault, automatically be transformed into II road three-phase input power supply, modular converter II work, otherwise when II road three-phase input power supply power failure or modular converter II fault, be automatically brought to I road input power supply, modular converter I work.When the equal fault of duplex feeding modular converter, can manually forward emergency supply circuit to.
Emergency supply circuit when Fig. 1 dotted line inside is divided into the equal fault of modular converter, as shown in the figure, the normally closed input of isolating switch QSA is disconnected receives respectively on the power supply circuits input terminal of I road, the input of often opening of isolating switch QSA is received respectively on the power supply circuits input terminal of II road, and the normally closed output of QSA is distinguished corresponding connection with the output of often opening of QSA; The input of circuit breaker SYQF is received the normally closed output of QSA respectively and is distinguished corresponding connection with the output of often opening of QSA; Isolating switch QSB often opens the output that input is received I, II road power supply modular converter circuit respectively, isolating switch QSB often opens the output that input is received circuit breaker SYQF respectively, the output of often opening of isolating switch QSB is distinguished corresponding linking to each other with the normally closed output of QSB, and receive respectively on output terminals A in the described power supply circuits, B, the C, under the normal power supply situation, isolating switch QSA gets to the optional position, and isolating switch QSB gets to upwards position, and circuit breaker SYQF is in off-state; When the two-way modular converter all breaks down, need earlier isolating switch QSB to be got to upper/lower positions with the emergency supply circuit power supply, close circuit breaker SYQF again, isolating switch QSA can get to the optional position, and these operations must be artificial hand-manipulated, and must operate in order.
Therefore, when I, the equal fault of II road power supply modular converter take place when, the whole not output of power supply panel, and this moment is unattended operation again, or operating sequence mistake during the manual operation emergency supply circuit, or under the normal power supply situation misoperation emergency service equipment etc., all can directly have influence on the operate as normal of station power consumption equipment.
Thus, the third power supply circuits that can change power supply when being necessary to provide the equal fault of a kind of railway intelligent power supply panel power supply conversion automatically replace manual emergency supply circuit, avoid the generation of the problems referred to above.
