Description
Technical field
The utility model relates to a kind of power supply system, particularly relates to a kind of large-scale aluminium electrolysis factory power supply system.
Background technology
Aluminum Electrolysis Production factory rules and regulations mould is increasing, there are a plurality of Aluminum Electrolysis Production series in general each factory, for it provides the galvanic voltage regulating rectifier transformer unit that 4～8 cover parallel runnings are arranged, above-mentioned voltage regulating rectifier transformer unit for the parallel running of Aluminum Electrolysis Production series is designated hereinafter simply as the user.
Though it is multiple that present method for user's power supply has, these methods cut both ways.Though some method is safe and reliable to operation, track investment is big, and the transmitting line corridor is taken up an area of many, can not make full use of the ability to transmit electricity of circuit.Though also can to solve track investment big for some method, many problems are taken up an area of in the transmitting line corridor, move that also basic security is reliable, but can not solve the problem of the ability to transmit electricity that makes full use of circuit.Though also some method has solved that track investment is big, the transmitting line corridor is taken up an area of many and can not make full use of the problem of the ability to transmit electricity of circuit, the safe reliability of operation has been subjected to influence again.Therefore above-mentioned method is all unsatisfactory.
The utility model content
The purpose of this utility model is: provide a kind of and guaranteeing under the power supply system prerequisite safe and reliable to operation, can effectively reduce track investment, make the circuit corridor take up an area of less, and can make full use of the large-scale aluminium electrolysis factory power supply system of the ability to transmit electricity of circuit, to overcome the deficiencies in the prior art.
The technical solution of the utility model: large-scale aluminium electrolysis of the present utility model factory power supply system, comprise first power supply and second source, first power supply is connected with second power supply buses with first power supply buses with the second source isolating switch through first power circuit breaker respectively with second source, first power supply buses is connected with one group of user's bus through one group of lead-in circuit breaker respectively with second power supply buses, and user's bus is connected with each user through user's isolating switch respectively.
In the said system, described user's bus is a double-bus, and double-bus comprises first bus and second bus.
In the aforementioned system, be provided with bus between described first power supply buses and second power supply buses.
Compared with prior art, when one or several user among all users is broken down when needing all devices in the failed subs criber all to trip, can realize that all isolating switchs all trip in the failed subs criber by the lead-in circuit breaker that disconnects failed subs criber in the utility model, the tripping operation that can may occur because of the isolating switch in each rectifier unit current supply circuit is not asynchronous, cause certain rectifier unit running overload, rectifier unit is safe.When first power supply (or second source) needs maintenance, can disconnect first power circuit breaker (or second source isolating switch), and connect bus, can both normally move system's safety in operation height to guarantee all users.
Because whole users only need two power supplys power supplies in the utility model, each power supply all can provide required whole loads for all users.Guaranteeing can effectively to reduce track investment under the power supply system prerequisite safe and reliable to operation, the circuit corridor is taken up an area of less, and can make full use of the ability to transmit electricity of circuit.

Fig. 1 is a structural representation of the present utility model.
Accompanying drawing is an example with two users.Being labeled as in the accompanying drawing: 1-first power supply, 2-second source, 3-first power circuit breaker, 4-second source isolating switch, 5-first power supply buses, 6-second power supply buses, 7-lead-in circuit breaker, 8-first bus, 9-second bus, 10-user's isolating switch, 11-user, 12-bus.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: Fig. 1 is a structural representation of the present utility model, and only having drawn among Fig. 1 is two users, and remaining user is identical with Fig. 1.Described user is meant the electrolytic series that is made of a plurality of electrolyzers, and overlaps the rectifier unit that voltage regulating rectifier transformers constitute for each electrolytic series provides galvanic by 4～8.Each Aluminum Electrolysis Production series production capacity 100～350Kt/ first, for each Aluminum Electrolysis Production series provides the galvanic voltage regulating rectifier transformer unit that 4～8 cover parallel runnings are arranged, about 80～the 140MV the first of each voltage regulating rectifier transformer unit unit capacity, the about 170～600MW of each electrolytic series power load.Existing each voltage of supply for user's power supply is generally 220KV or 330KV, and the size of the visual electrolytic series power load of the transmission capacity of its circuit is a plurality of series power supplies simultaneously.
Large-scale aluminium electrolysis of the present utility model factory power supply system comprises first power supply 1 and second source 2, during making, first power supply 1 is connected with second power supply buses 6 with first power supply buses 5 with second source isolating switch 4 through first power circuit breaker 3 respectively with second source 2, first power supply buses 5 is connected with one group of user's bus through one group of lead-in circuit breaker 7 respectively with second power supply buses 6, and user's bus is connected with each user 11 through user's isolating switch 10 respectively.Described user's bus is a double-bus, and double-bus comprises first bus 8 and second bus 9.Be provided with bus 12 between described first power supply buses 5 and second power supply buses 6.
The utility model method be that all users are powered by two power supplys, two power supplys are connected with two power supply buses through power circuit breaker respectively; Each user is connected with separately user's bus through user's isolating switch, and two user's buses are connected with two power supply buses through lead-in circuit breaker respectively, connect through bus between two power supply buses.Described user is meant the electrolytic series that is made of one group of electrolyzer, and provides galvanic one group of voltage regulating rectifier transformer unit for each electrolytic series.The capacity of described two power supplys all can satisfy whole loads of all users.
Principle of work of the present utility model is as follows:
Only use first power supply (second source) power supply during the utility model works better, first power supply (second source) is connected with second power supply buses with first power supply buses through first power circuit breaker (second source isolating switch).When first power supply (second source) when needing interruption maintenance, can cut off first power circuit breaker (second source isolating switch) that is connected with first power supply (second source), and then the second source isolating switch (first power circuit breaker) that is connected with second source (first power supply) of connection, second source (first power supply) is connected with second power supply buses with first power supply buses.Two power supplys constitute the syndeton of the using and the reserved, can be by any one power supplies in two power supplys, and another maintenance can not influence production.
If there is one or several user to break down when maybe needing to overhaul, only the pairing lead-in circuit breaker 7 of open failure user and user's isolating switch 10 get final product successively, do not influence other user's normal operation.
