The utility model relates to a compensating starting device of the diesel locomotives, which comprises a capacitor C, a diode D, a thyristor T, a current limited resistance R; a storage battery group XDC, a storage battery switch XK, a starting contactor QC and a starting motor QD, wherein, the starting contactor QC and the starting motor QD are in series; the thyristor T and the current limited resistance R are sequencely connected in series, the anode of the diode D is connected with the negative electrode of the starting motor QD, one end of the current limited resistance R is connected with the positive electrode of the starting motor QD; a resistance R1 and a starting button IQA are connected in series between the triggering end of the thyristor T and the negative electrode of the capacitor C; the positive electrode of the capacitor C is connected with the sending end of the starting contactor QC by the battery switch XK, the negative electrode is connected with the cathode of the diode D. The utility model is characterized in that: at the transient of the starting of the motor QD, the powerful starting current is mainly provided by the capacitor C, the battery XDC only plays an auxiliary role, thus the impact to the battery by the starting current is reduced greatly, the service life of the battery is prolonged, the purpose of starting machines frequently is achieved, the alerting operating time of the diesel locomotives is reduced, the mechanical wear is decreased and the fuel oil is saved.
Description
Technical field
The utility model relates to the starting drive of internal combustion locomotive, exactly is internal combustion locomotive compensation starting drive.
Background technique
Present internal combustion locomotive adopts storage battery directly to start, because capacity of battery is limited, therefore can not frequently open machine, directly influences traffic safety.Simultaneously, do not allow when locomotive is awaited orders to shut down yet, and then cause the unnecessary wearing and tearing of machinery, and waste a lot of fuel oils.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of and can frequently opens machine, reduces storage battery moment overdischarge, reduces mechanical wear, fuel-efficient internal combustion locomotive compensation starting drive.
The technical solution of the utility model is such, and internal combustion locomotive compensation starting drive structure comprises battery pack XDC, storage battery disconnecting link XK, starting contactor QC, capacitor C, diode D, thyristor T, current-limiting resistance R, start button IQA, resistance R 1; Battery pack XDC, storage battery disconnecting link XK, starting contactor QC are connected in series with starting electrical machinery QD; Thyristor T and current-limiting resistance R are connected in series in proper order, and the anode of diode D inserts the negative pole of starting electrical machinery QD, and current-limiting resistance R one termination is gone into the positive pole of starting electrical machinery QD; Be serially connected with resistance R 1 and start button IQA between the trigger end of thyristor T and capacitor C negative pole; The capacitor C positive pole joins by the sending end of storage battery disconnecting link XK and starting contactor QC, and negative pole is connected on the negative electrode of diode D.
Characteristics of the present utility model are: start moment at motor QD, powerful inrush current is mainly provided by capacitor C, storage battery XDC only helps out, reduced the impact of inrush current greatly to storage battery, can prolong the working life of storage battery, and realize and frequently to have opened machine, reduce internal combustion locomotive and awaited orders running time, reduce mechanical wear, saved fuel oil.
Description of drawings
Fig. 1 is the circuit diagram of internal combustion locomotive compensation starting drive;
Embodiment
As shown in Figure 1, battery pack XDC, storage battery disconnecting link XK, starting contactor QC are connected in series with starting electrical machinery QD; Thyristor T and current-limiting resistance R are connected in series in proper order, and the anode of diode D inserts the negative pole of starting electrical machinery QD, and current-limiting resistance R one termination is gone into the positive pole of starting electrical machinery QD; Be serially connected with resistance R 1 and start button IQA between the trigger end of thyristor T and capacitor C negative pole; The capacitor C positive pole joins by the sending end of storage battery disconnecting link XK and starting contactor QC, and negative pole is connected on the negative electrode of diode D.
During use, press start button IQA, thyristor T conducting, battery pack XDC charges to capacitor C by thyristor T, current-limiting resistance R, starting electrical machinery QD.When starting contactor QC was closed, battery pack XDC and capacitor C were given starting electrical machinery QD power supply simultaneously.Because the capacitor C internal resistance is less than the internal resistance of battery pack XDC, most of electric current is provided by capacitor C, and then reaches the machine that can frequently open, and reduces storage battery moment overdischarge, reduces mechanical wear, fuel-efficient purpose.
