Description

Interlock tripper for DC traction power-supply system

The invention belongs to the power-off protection apparatus in the DC traction power-supply system.

In the DC traction power-supply system that adopts two way feeding.When near traction substation one side when being short-circuited fault, the short circuit current that is reacted to near-end substation is very big, and it is just much little to be reflected to the short circuit current of far-end substation, even can be less than the locomotive starting current of this station near-end.In this case, the relaying of DC traction switch wants to satisfy simultaneously the requirement of running current and short circuit current, just need take some special measures, and it is one of method of using always that bilateral jumping protection is set.It is that DC supply switch with two ends substation links up with electric control cable that traditional connection is jumped protection; when the short circuit current that is reacted to near-end substation makes this stand erectly the stream switch trip; make the corresponding switch trip of remote station simultaneously by the electrical communication of control loop; so just can be when satisfying big running current, the dead band of eliminating the far-end short circuit current.Bilateral jumping protection is simple and reliable; up to the present, be that China adopts most widely used protected mode in the DC traction power-supply system of two way feeding, but this traditional bilateral jumpings protection need road along the line total length laying electric control cable always; function singleness, cost are also than higher.

Characteristics of the present invention are that this device comprises two identical subsystems, are separately positioned in two substations of two way feeding, and a pair of circuit that can use the subway communication system between two subsystems carries out full duplex communication as passage.As mainframe computer, the state to direct-current traction power supply switch in standing separately carries out circle collection, the track analysis to each subsystem respectively with a 8-bit microcontroller (8031).When confirming to need " connection is jumped ", notify another subsystem controls the other side switch trip, finish " connection is jumped " function.

Owing to use communication channel and finish two contacts between substation in the light current mode; jumping device with traditional connection compares; saved the expense of laying the electric installation cable along whole power supply section; novel jumping device is jumped device than the tradition connection and is reduced investment outlay more than 80%; because micro controller system (8031) function is stronger; system real time is better; this device not only can be finished " connection is jumped " function; and can distinguish pass breaking reason; only, both guaranteed the sensitieness of protection, guaranteed reliability again the other side's " connection is jumped " that sends a notice of the situation because of short circuit tripping operation; can avoid when non-short circuit breaking blindly " connection is jumped ", enlarge the power failure scope and influence driving.This device can also record, analyzes the switch running state, provides the maintenance prompting according to operating standard in good time.This device also has functions such as sound, light demonstration, printing, intelligent degree is higher, the man machine interface close friend, easy to use, can prevent the watch keeper owing to the error of lacking experience or inadvertent causes to a certain extent, so can not only finishing traditional connection, this novel jumping device jumps function, and the serviceability that improves DC power-supply system there is certain help, consider that the interference of subway running environment is more, novel jumping device has adopted a large amount of anti-dried measures, and antijamming capability is stronger.Owing to adopt modular construction, change promptly can be used for unattended substation a little.

Embodiments of the invention are as shown in drawings:

In conjunction with the accompanying drawings technical solution of the present invention is specified:

What accompanying drawing was represented is the micro-processor controlled jumping of separate unit device, and fitness for purpose is established one respectively between adjacent station in actual use, uses with communication channel UNICOM.

Unit work can have three kinds of situations respectively under different software supports:

One: as figure one, figure two, figure three tie lines.Use software I.

Connection is jumped the displacement situation of device by four switch auxiliary nodes of collection acquisition circuit terminal row 1-8 circle collection on the case backboard, learn with this whether switch has the breaking situation, after finding the switch breaking, whether the current relay of gathering this switch moves, it is the fault tripping operation that action specification is arranged, and sends signal by communication line to remote station.After remote station receives signal, drive corresponding switch trip by relay circuit.If current relay does not have action, only transmit sub-gate signal to remote station.More than all sound, the light of each situation two station arrangement show, record, print.

Its two: as figure one, figure two, figure three wiring.Use software I I.

The 13-16 of acquisition of signal terminal row connects the end of a pair of node of the opening button of 1-4# switch, other end connecting terminal 12 respectively among the figure three.After finding to close breaking, check earlier to have or not artificial sub-switching operation, just transmit sub-gate signal if having, do not have, then transmit trip signal.All the other are with first kind of condition of service.

Its three: as figure four, figure two, figure three wiring.Use software I II.

On the acquisition of signal loop terminals row of case backboard, terminal 1-10 wiring is used with first kind, gathers switch auxiliary node displacement signal, and terminal 11-14 can gather the switch trip signal as first kind of condition of service; Also can gather the manual brake separating signal as second kind of use.When carrying out connection jumping function, with first kind or the third condition of service.Eight relays on the BASE 8860 are connected on the lead-out terminal row, and

Several service conditions as " connection is jumped " system.

1. system can be a base unit with a two way feeding section, two " limits " in two way feeding respectively adorn a table apparatus, (Φ＜0.4mm) connects or uses a pair of communication channel and connects, and the correspondence station connection that each table apparatus only is responsible for the same side is jumped function (comprise the reclosing of this side switch of our station, reclosing judge) to use twisted-pair feeder between two table apparatus.

2. a table apparatus can be controlled whole dc switchs in the traction substation, and the device at while and station, both sides connects by transmission line, and the switch connection that relies on the software communication landmark identification to belong to that side is jumped.All the other are with 1.

3. when using optical cable as communication channel, the BM-2 line driver can be replaced by the optic electric interface device, the junction style of optic electric interface device and mainboard is constant.

4. at unattended substation, software be can adjust, sound, lightshow function no longer established.The human-machine interface oralia only keeps " switch withdraws from connection and jumps button ", uses during for inspection switch.

The unit circuit of system controlled by computer formula interlock tripper of the present invention can adopt integrated measure to make special-purpose integrated circuit block, belongs to interest field of the present invention.
