| Various products for trolleybus driving equipment |
|
The
trolleybus driving equipment, along the chopper and the microprocessor
control unit, is made of several products, designed and sized for
every particular type of trolleybus and traction motor. |

| |
 |
Radio interference filter: ensures
the limitation of the electromagnetical perturbations due to the
traction equipment, within the standard limits. |
| |
|
Motor choke:
mounted in series with the traction motor, for the limitation of the current
wavings through the motor, and for the limitation of the braking
voltage in the electrical equipment. |
| |
|
Line choke: the
choke, together with the filter capacitor, limits the line current
and line voltage wavings. |
| |
|
Filter capacitor: the
filter capacitor, together with the line choke, limits the line
current and line voltage wavings. |
| |
|
Line voltage sensor: ensures
a closed contact relay when the filter capacitor voltage grows beyond
a certain value, the output signal being galvanic separated from
the input voltage. |
| |
|
Pre-excitation source: its task is to pre-excite
the traction motor when entering the braking state. |
| |
|
Dangerous voltage sensor: monitors
if the vehicle's body voltage rises above a certain value, giving
the high voltage interruption signal at the equipment terminals. |
