.. 2 is a chopper device, and /3 is a W4 column resistor. Note that the chopper opener 10 and/or are in a closed and open state, respectively, under normal conditions, and do not exhibit the opposite state when an abnormality occurs, such as when the chopper is opened.
今、電気車が正常運転状態にあるとずれば、−ヒ述のと

す。Now, assuming that the electric car is in normal operating condition, the chopper opener/θ is closed and the opener/l is open as described in (b), so the shunt field current is transmitted by the chopper device 7.2. The electric car is controlled and driven along the characteristic curve shown in Figure 1. That is, FIG. 2 shows a characteristic notch curve when the field chopper is normal, and the vertical axis is the speed (V), and the horizontal axis is the armature current (Ia). -[-櫨 is the current on the negative side, -I. represents the regenerative side current.

短絡して行(ように制御すれば、電機子電流Iaに対し
速度Mは第2図の抵抗進段ステップ/グの矢印に従って
上昇する。そして最終的には起動抵抗器グを経て短終し
た特定曲線/左になって更に速度は上昇する。In No. 1 Nj and Fig. 2, when the current interrupters Ko and S are turned on, the current limited by the starting resistor Da flows into the main electric machine armature circuit, and the chopper device /-1 flows into the shunt field circuit.
A controlled field current flows, and the electric car is driven in full force. The electric machine preload Ia is limited by the starting resistor G, but when it decreases to a constant value Ia, the starting resistor G is successively short-circuited and the speed M becomes The speed increases according to the arrow of the resistance advancement step/g in Figure 2.Finally, the speed increases further as it passes through the starting resistor and reaches a short-terminated specific curve/to the left.
このように電機子電流1aが変化するとき、分巻界磁電

流1h巻電動機と同じ特性を得ることができろ。When the armature current 1a changes in this way, if the shunt field current is controlled by the chopper device 7.2 in proportion to the armature current Ia, as shown in FIG. It should be possible to obtain the same characteristics as a DC 1-hour winding motor for a conventional electric car.
また!時性曲線/Sは、電機子1b7流Iaが減少する

、界磁チョッパ動作が正常な時は、チョッパ装置/2の
制御により電機子電流は負、即ち回生側になら1−安定
したカ行運転が達成できろ。Also! When the armature 1b7 flow Ia decreases, the chopper device 7.2 also reduces the shunt field current, so the time curve /S shows that the series motor characteristics and the armature current Ia change as shown in Figure 2. The speed IBj M only increases while decreasing, and the regenerative current -Ia does not become the same. Furthermore, at this time, if there is a sudden drop in the voltage in the overhead line box, the induced voltage of the main motor 3 becomes higher than the overhead line voltage, and the armature current Ia suddenly decreases to ('; l and becomes the regenerative current -Ia. Chopper device7.
2 reduces the shunt field current, so the main 'dL motor voltage does not drop and the regenerative current -IaK does not occur. In this manner, when the field chopper operates normally, if the armature current is negative, that is, on the regenerative side, under the control of the chopper device/2, stable forward operation can be achieved.
次に↑h:磁チョッパ動作に故障が生じた場合について
考える。Next, consider the case where ↑h: a failure occurs in the magnetic chopper operation.

), the electric cars will get stuck and the operating schedule will be disrupted, so a chopper opener 10 and // are installed as shown in Figure 1, and each time the opener 10 is opened and the opener // is closed, the electric car is operated Measures have been taken to allow this to continue. That is,
In this case, when the current interrupters C and S are turned on, a constant shunt field current limited by the series resistor /3 flows in the shunt field circuit.

ていた。Vertical 1) 11 in Figures 2 and 3 represents the speed (v+), but it also represents the terminal voltage of the main motor 3 along with the speed. Therefore, the resistance value of the starting resistor in Figure 3 is zero. A certain characteristic curve /S shows the terminal voltage of the main 'r[i; When running for a long time with the characteristic curve /S with the starting resistor G short-circuited when it is open, it will be affected by overhead line voltage fluctuations, and the armature current Ia will fluctuate rapidly, and in some cases, the armature current Ia will fluctuate rapidly. Or, when the current suddenly changes to the regenerative current, problems occur in the operation of the electric generator.
