Overview
The Circuit-breaker function block represents the physical switch in the SIPROTEC 5 device.
The basic tasks of this function block are the operation of the circuit breaker and the acquisition of the circuit-
breaker auxiliary contacts and other circuit-breaker information.
The Circuit-breaker function block also provides information about:
•
Number of switching cycles
•
Breaking current, breaking voltage, and breaking frequency
•
Summation breaking current
5.6.5.2
Tripping, Opening, and Closing the Circuit Breaker
The circuit breaker is operated in the following situations:
•
Tripping of the circuit breaker as a result of a protection trip command
•
Opening of the circuit breaker as a result of control operations
•
Closing of the circuit breaker as a result of automatic reclosing or control operations
Tripping is always the result of a protection function. The operate indications of the individual protection func-
tions are summarized in the Trip logic function block. The trip command that causes the tripping in the
Circuit breaker function block is generated there. 1-pole or 3-pole tripping is possible depending on the
configuration, parameterization or even the protection function (see also
To operate the circuit breaker, the Circuit-breaker function block provides the output signals (see
that must be routed to the corresponding binary outputs of the device.
