ensure secure and controlled
switching the high power, the three interrupters are
controlled electronically. The power
circuit breaker consists three insulator columns with
one operating unit each and shared control unit. Con
sequently, Han® HPR housings and seals have been cho
sen and have been specially developed withstand these
types stress.
The relevant environmental conditions have taken
into account the circuit breaker can used outdoors. The
insulator columns each contain interrupter unit and
the necessary drives.
This connection realized using conductor special
cables transmit the sensor and actuator signals.
