德意志民主共和国的格·巴依木列尔电机车制造厂于1964年为苏联试制了两台直流和两台交流牵引联动机车。直流牵引联动机车(图1)是由一台操纵电机车和一辆马达自翻车组成。操纵电机车是大批生产的ЕЛ-2型电机车为基础制造的,所不同的,是在机车上多装了一套为调节马达自翻车牵引电动机端子电压及其保护所必须的电气设备。设在司机室内的电气设备箱加大了一倍;为保护马达自翻车电动机的动力回路,在机器室内加设了第二个高速断路器《Γеарапид》。
In 1964, the Georgia-Burgundy locomotive factory in the German Democratic Republic trial-built two DC and two AC traction linkage locomotives for the Soviet Union. DC traction linkage locomotive (Figure 1) is composed of a control electric locomotive and a motor from the rollover. Manipulated electric locomotives are manufactured on the basis of mass-produced ЕЛ-2 electric locomotives. The difference is that an electrical equipment necessary for adjusting the motor voltage and the protection of the motor from overturning is provided on the locomotive. The electrical equipment box located in the cab has been doubled. To protect the power circuit of the motor from the rollover motor, a second high-speed circuit breaker “Γеарапид” has been added to the machine room.
