Description
The present invention relates to a kind of power circuit Fuel Pressure Regulator Control of AC-DC electric locomotive method, particularly a kind of power circuit Fuel Pressure Regulator Control of Shaoshan 3B type electric locomotive method.
The transfer of energy of Shaoshan 3B type electric locomotive power circuit is to be converted to adjustable vdc from the power supply of contact system 25KV industrial frequency AC via main transformer step-down, voltage regulating rectifier device at present, offers traction electric machine and carries out the task that drags.Its voltage regulation mode adopts not three sections half-controlled bridge type sequential phase controls of five equilibrium voltage regulation mode of main transformer low pressure side thyristor, i.e. first section a1-x1-T11, T12, D11, D12 (a2-x2---T21, T22, D21, D22) bridge pressure regulation, rectifier bridge input voltage 1071V (zero load), by control T11, T12 (T21, T22) arm thyristor conduction angle, make VD extremely by 0 smooth adjustment
Ud, (Ud is a voltage regulating rectifier device output total voltage) is up to the full conducting of T11, T12 (T21, T22) thyristor.Second section a3-b3---T13, T14, D13, D14 (a4-b4-T23, T24, D23, D24) foot bridge pressure regulation, rectifier bridge input voltage 535.5 V (zero load), by control T13, T14 (T23, T24) arm thyristor conduction angle, make VD by
The Ud smooth adjustment extremely
Ud is up to the full conducting of T13, T14 (T23, T24) thyristor.The 3rd section b3-x3-T15, T16, D13, D14 (b4-x4-T25, T26, D23, D24) foot bridge pressure regulation, rectifier bridge input voltage 535.5 V (zero load), by control T15, T16 (T25, T26) arm thyristor conduction angle, make direct current output by
The Ud smooth adjustment is to Ud, until the full conducting of T15, T16 (T25, T26) thyristor.
The shortcoming that this mode produces is, sacrificed the intrinsic power factor specification of locomotive, causes the average power factor of locomotive to drop to below 65%, both wasted electric energy, causes electric network pollution, reduced the tractive output of locomotive again.
Purpose of the present invention is intended to overcome above-mentioned shortcoming, can improve locomotive power factor and tractive output effectively for Shaoshan 3B type electric locomotive provides a kind of, saves electric energy, reduces electric network pollution, implements economical and practical again economic four-section half-controlled bridge type phase control method.
The object of the present invention is achieved like this:
Shaoshan 3B type electric locomotive power circuit traction control mode is to rely on the electronic control cabinet generation and be sent to silicon unit silicon controlled trigging pulse at present, presses the conducting order of T11, T12 in Fig. 1 circuit (T21, T22) → T15, T16 (T25, T26), finishes

Three sections bridges of Ud are (T11 etc. are thyristor) of five equilibrium sequence control mode not.Task of the present invention is under the condition that does not change main circuit of electric locomotive, with Shaoshan 3B type electric locomotive power circuit traction control mode, change into (
Ud →
Ud) →
Ud (withdraws from preceding two simultaneously
Ud) →

Ud) → voltage regulation mode of Ud reaches the object of the invention.
That is: when the locomotive traction operating mode, main transformer ZB low pressure side a1-x1 and a3-b3-x3, the same respectively 1ZGZ of a2-x2 and a4-b4-x4 winding, 2ZGZ silicon rectifier device constitute the economic four-section half-controlled bridge type voltage regulating rectification circuit of two bogie individual power supplies separately, and its control program is:
At first,---T13, T14, D13, D14 (a4-b4---T23, T24, D23, D24 to a3-b3) foot bridge pressure regulation, rectifier bridge input voltage 535.5V (zero load) by control T13, T14 (T23, T24) arm thyristor conduction angle, makes VD by 0 smooth adjustment extremely
Ud is until the full conducting of T13, T14 (T23, T24) thyristor.
Then,---T15, T16, D13, D14 (b4-x4---25, T26, D23, D24 to b3-x3) the foot bridge pressure regulation, rectifier bridge input voltage 535.5 V (zero load), by control T15, T16 (T25, T26) arm thyristor conduction angle, make VD by
The Ud smooth adjustment extremely
Ud is until the full conducting of T15, T16 (T25, T26) thyristor.
When the full conducting of T15, T16 (T25, T26) thyristor, promptly VD reaches
Ud+
Ud=
During Ud, by control T11, T12 (T21, T22) arm thyristor conduction angle, make its full conducting,---T11, T12, D11, D12 (a2-x2---T21, T22, D22, D21, D22 to a1-x1) the bridge pressure regulation, rectifier bridge input voltage 1071V (zero load) reaches VD
Ud, simultaneously, by control T13, T14 (T23, T24) arm thyristor conduction angle and T15, T16 (T25, T26) arm thyristor conduction angle, make its Close All, withdraw from first section a3-b3-T13, T14, D13, D14 (a4-b4---T23, T24, D23, D24) foot bridge pressure regulation and second section b3-x3---T15, T16, D13, D14 (b4-x4-T25, T26, D23, D24) foot bridge pressure regulation, promptly withdraw from preceding two
Ud.Afterwards, again a3-b3-T13, T14, D13, D14 (a4-b4---T23, T24, D23, D24) foot bridge are carried out pressure regulation, rectifier bridge input voltage 535.5 V (zero load), by control T13, T14 (T23, T24) arm thyristor conduction angle, make VD by
The Ud smooth adjustment extremely
Ud is until the full conducting of T13, T14 (T23, T24) thyristor.At last, again to b3-x3-T15, T16, D13, D14 (b4-x4---T25, T26, D23, D24) foot bridge pressure regulation, rectifier bridge input voltage 535.5 V (zero load), by control T15, T16 (T25, T26) arm thyristor conduction angle, make VD by
The Ud smooth adjustment is to Ud, until 15, T16, the full conducting of (T25, T26) thyristor, thereby finished control to economic four-section half control bridge.How not change under Shaoshan 3B type electric locomotive power circuit condition, realization by three sections present bridges not five equilibrium sequence control mode change into and realize economic four-section half control bridge mode, key is to change the order that electronic control cabinet produces trigging pulse, promptly must change the sequential logic circuits in the pulse formation plug-in unit in the electronic control cabinet.The invention provides the pulse formation decision circuit of realizing Shaoshan 3B type electric locomotive economic four-section half control bridge mode.
Good effect of the present invention is: the China Railway task is heavy, number of locomotives is wretched insufficiency, bear cloud at present, expensive, surplus Shaoshan 3B type electric locomotive of the busy transportation burden in valley district has only 160, situation does not allow the power circuit of locomotive is done big change, economic four-section half-controlled bridge type phase control method, under this urgent situation, create, this traction control mode, the power factor that makes locomotive is by bringing up to 78%～80% less than 65% originally, its aviation value improves 14% before transforming, both saved and used electric energy, reduce reactive volt-amperes, improved tractive output widely, increased transportation volume, improved locomotive again effectively, usage ratio of equipment makes line voltage stable, reduced electric network pollution.
