The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Referring to Fig. 1, move the car scheme in the alternating current drive locomotive external direct current power supply storehouse of the embodiment of the invention, single core storehouse socket XSM3/XSM4 that a DC250V voltage class respectively is installed in the locomotive underframe both sides, the positive pole of DC70V external source can be introduced locomotive, and by rail → wheel → earth system → car body ground, the negative pole of the DC70V ground power supply of outside is introduced locomotive, link to each other with the intermediate loop negative pole of traction convertor 2.
Referring to Fig. 2; move the car device in the AC transmission electric power locomotive external direct current power supply storehouse of present embodiment; the DC70V external source is connected to the input end of input rectifying bridge one side among the traction convertor circuit TI with switch QS3 by the storehouse; be serially connected in the precharge protective circuit of external direct current power supply anode; by being formed in parallel with contactless switch KM41 after 41 series connection of contactless switch KM42 and resistance R, the ground protection resistance that one pole change-over swith QS4 links to each other with Support Capacitor mid point among the traction convertor circuit TI is connected in series.
When carrying out moving car in the storehouse, first locomotive is placed to disconnect line circuit breaker and fall arciform attitude, main transformer MT and traction convertor circuit disconnect.By socket XSM3 or XSM4 external direct current power supply is introduced locomotive.Then disconnect the one pole change-over swith QS4 in the traction convertor TI, closed storehouse switch QS3 connects the DC70V external direct current power supply, and the reversing handle with the manipulatable end controller leaves zero-bit again.Precharge contactless switch KM42 is closed, with resistance R 41 incircuits, can not cause excessive rush of current to traction convertor TI intermediate loop when guaranteeing the external source initial charge.When the intermediate circuit voltage for the treatment of traction convertor circuit TI reached standard voltage value when moving car (present embodiment is 60V), Operating In Persistent Current Mode contactless switch KM41 fell resistance R 41 short circuits.The governor handle of manipulatable end controller is left zero-bit, and (0~3Hz) makes locomotive realize that low speed moves to traction convertor TI output variable frequency alternating current power source.
Because the DC70V power supply frequently is switched on or switched off with the crawl form, for fear of frequent closure and the disconnection to the impact of traction convertor TI and precharge contactless switch KM42 and work contactless switch KM41, only have precharge contactless switch KM42 closed during precharge, complete work contactless switch KM41 to be charged and precharge contactless switch KM42 all are in closure state.When input power disconnected with a flowing mode, as long as the controller reversing handle does not return zero-bit, the precharge contactless switch continued to remain closed, and work contactless switch KM41 treats to disconnect when intermediate circuit voltage is lower than 60V, and is again closed when returning to 60V.So both guaranteed can not produce large rush of current when input power is sent into traction convertor TI with a flowing mode, can also reduce the switching number of times of precharge contactless switch KM42 simultaneously, improved its service life.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
