- Switching unit 12 of a high voltage circuit breaker 10th is usually referred to as an interrupter unit (UE) net.
- the corresponding switching device 14 has a longitudinal axis 20.
- the switch housing 16 is designed such that it takes over this longitudinal axis 20, so that the longitudinal axis 20 is also the longitudinal axis of the complete switching unit 12.
- the high-voltage circuit breaker 10 further includes a Einschaltwiderstandsech (EWID unit) 22 with a Einschaltwiderstandsan kann (EWID arrangement) 24 and the Einschaltwiderstandsanord opening 24 einheinenden Einschaltwiderstandsgephase 64 on.
- the starting resistor arrangement 24 also has a longitudinal axis 28.
- the switch-on resistor housing 26 is designed such that it takes over this longitudinal axis 28, so that the longitudinal axis 28 of the switch-on resistor arrangement 24 is also the longitudinal axis of the complete switch-on resistor unit 22.
