It is linked togather, often moves down a resistor 10, resistor 10 parallel value 0.006 Ω less than parallel value above, conversely, work as
When resistance box 9 moves up, often move up a resistor 10, the parallel value ratio of each resistor 10 does not move in resistance groove 2
Big 0.006 Ω when dynamic；The like, in resistance box 9, each layer resistor 10 resistance is different, an often many and resistor 10, namely
Resistance box 9 often moves down a resistor 10 in resistance groove 2, and its value is than little 0.006 Ω before not moving.
Process of the test：As shown in Figure 1,3, start locomotive first, according to《Locomotive Loading Test technique》Operated,
Resistance box 9 in two resistance grooves 2 of Fig. 1 middle left and right is in complete full state, upper limit position switch 5 (XK1/2) and lower limit
Switch 19 (JK1/2) just interlocking closure, instead interlock and open；Press resistance box 9 and rise button QA1, due to the upper limit in right resistance groove 2
Bit switch 5 (XK2), lower position switch 19 (JK2) are just being interlocked in closure position, and catalyst 1C+ obtains electric, and in left resistance groove 2, two subtract
Fast machine 5 rotates forward, and resistance box 9 rises, and such as Fig. 3 shows, now, left resistance groove 2 ventilation motor 1 operates, and is contained in left resistance groove 2 bottom
Limit switch 19 (JK1) discharge, its just interlock open, anti-interlocking closure；Not rising in the resistance box 9 of left resistance groove 2 makes limit
Under bit switch XK1 release conditions, just interlocking still in closure position, anti-interlocking is opened.Press resistance box 9 and decline button QA2, by
It is in closure position in now limit switch JK1, limit switch XK2, JK2 are just interlocking closure, therefore catalyst 1C- obtains electric, left resistance
Groove 2 reducing motor 5 inverts, resistance box 9 declines, and left resistance groove 2 ventilation motor 1 operates, and is in work when dropping to limit switch JK1
When using position, its anti-interlocking is opened, catalyst 1C- dead electricity, and in left resistance groove 2, reducing motor 5, ventilation motor 1 stop.At this moment anti-again
Come over to press rising button QA1, in left resistance groove 2, resistance box 9 rises, and ventilation blower 1 operates, limit switch JK1 discharges.When left electricity
When in resistance groove 2, resistance box 9 has risen last resistor band 10, limit switch XK1 discharges, and it is just interlocked and opens, instead interlocks and close
Close, catalyst 1C+ dead electricity, in left resistance groove 2, reducing motor 5, ventilation blower 1 stop.Continue to press rising button QA1, catalyst
2C+ obtains electric, and in right resistance groove 2, reducing motor 5 rotates forward, and resistance box 9 rises, and ventilation blower 1 operates.If now release rises button
QA1, press that decline button QA2 situation is identical with above-mentioned, catalyst 2C- obtains electric, and in right resistance groove 2, reducing motor 5 inverts, resistance
Case 9 declines, and ventilation blower 1 operates.Release declines button QA2, then presses rising button QA1, and right resistance groove 2 reducing motor 5 rotates forward, electricity
Resistance case 9 rises, and ventilation blower 1 operates, when in right resistance groove 2, resistance box 9 has risen last resistor band 10, limit switch
XK2 discharges, its just interlock open, anti-interlocking closure, now catalyst 2C+ dead electricity, reducing motor 5 in right resistance groove 2, ventilation electricity
Machine 1 stops, and sound and light alarm sounds simultaneously, and all resistors 10 are away from resistance groove 2, then presses reactionless during rising button QA1.Press
When declining button QA2, in right resistance groove 2, resistance box 9 declines, the such lifting process repeatedly of resistance box 9 in two resistance grooves 2.Cause
It is that there is one normally opened one normally closed compound button for rising button QA1 and decline button QA2, from figure 3, it can be seen that press upper simultaneously
Rise button QA1 and decline button QA2 when always have one inoperative.Draw from the above mentioned, resistance box 9 in only left resistance groove 2
After rising to top, in right resistance groove 2, resistance box 9 just can rise or fall, and same only have when in right resistance groove 2, resistance box 9 declines
To after low side, in left resistance groove 2, resistance box 9 just can rise or fall.
