The device rapidly powers off and then transmits power by a switch arranged on the ground to realize that the motor train unit passes through the slit phase in a non-breaking mode so as to guarantee the operating speed and operating time of the motor train unit, realizes the stable split phase passing, is suitable for large-scale popularization and application and has great production practice significance.
Description
Technical field
The utility model relates to power system of electric railway high voltage supply technical field, particularly relates to the non-shut-brake automatic neutral-section passing device of a kind of EMU.
Background technology
At present, electric railway adopts the tractive power supply system of single-phase 25kV, power to electric rail car group or motor train unit through contact system feeding section by substation along the railway track top, the length of each feeding section is generally 25 to 45 kilometers, because the phase place of two adjacent feeding sections is often inequality, can not link together, therefore, be provided with a neutral section form between two adjacent feeding sections, this neutrality section also is one section contact system.
Between the contact system feeding section of described neutral section and both sides a fracture being arranged respectively, is respectively into section fracture and the section of going out fracture, by these two fractures, realizes the feeding section of neutral section both sides is kept apart.The length of neutral section generally has 400 meters to 500 meters, and does not have mechanical the connection with the both sides feeding section, and this neutral section that has fracture is called phase-splitting on electric.
During concrete the operation, EMU slides to the section of the going into fracture of neutral section from the contact system feeding section of phase-splitting (promptly neutral section) side, enter neutral section from the section of going into fracture again, leave neutral section through the section of going out fracture again and arrive the contact system feeding section of phase-splitting opposite side, this process was called phase-splitting.
For EMU, it is to obtain energy in the contacting of pantograph and contact system by the top, in the motor train unit walking process, pantograph also slides together and contacts with contact system all the time along with motor train unit, therefore can continuously obtain electric current from contact system, if under motor train unit on-load situation, pantograph from the contact system feeding section of alive part when uncharged neutral section slides, pantograph is in the process of progressively leaving alive part, will cause the arcing phenomenon occurring between the contact system feeding section of pantograph and alive part, this electric arc can produce very big heat at short notice, even blow contact system, cause serious safety misadventure, this situation is called the motor train unit on-load and rushes phase-splitting, on the contrary, if the motor train unit undue phase time of on-load not, because can not form current return, above-mentioned arcing phenomenon just can not appear.
In order to solve above-mentioned arcing problem, traditional motor train unit are crossed the method that phase-splitting mainly adopts, before motor train unit are crossed phase-splitting, just with the vehicle-mounted circuit breaker automatic brake separating of the major loop on the motor train unit, make the motor train unit major loop descend phase-splitting in the cut situation of load, the feature of this method is, on the track circuit of neutral section both sides, the motor train unit responser is installed all, responser generally has 300 meters distance apart from neutral section, when before motor train unit enter neutral section, at first passing through the position of responser, responser elder generation driving motor train unit subtract the master and are loaded to zero, drive the circuit breaker trip of body again, but motor train unit outages pantograph are not landed to slide again and are entered into a section fracture, the neutral zone, the section of going out fracture leaves phase-separating section at last, thereby realizes passing through phase-splitting.But, the greatest problem of this method is when having only the permutation motor train unit to leave phase-separating section fully, just can reload, therefore undue phase time loses the chronic of tractive force, be generally tens seconds, simultaneously, because the every undue phase time of motor train unit promptly has been cut off power supply, rely on the inertia of motor train unit to slide phase-splitting, therefore the motor train unit speed of crossing phase-splitting can reduce greatly, if just cut off once every 25 kilometers circuit breakers, will prolong the time of train occupation track circuit greatly to 45 kilometers motor train unit.
Therefore, press at present and develop a kind of device, can realize that motor train unit are non-shut-brake by phase-splitting, guarantee the running velocity and the time of run of motor train unit.
