Description of software determining optimum maintenance sequence for 110 kV power circuit breakers with SF_6

摘要

The third stage of work on the development of Reliability Centred Maintenance (RCM) software for distribution system network elements is described. Analysed is particularly the case of a 110 kV power circuit breakers with SF_6. The software design is based on RCM software and previously developed software for the maintenance of 110 kV VMM power circuit breakers and 110 kV/MV transformers. When determining an optimum maintenance sequence, the appropriate parameters of technical conditions and operational importance are required. The paper describes the structure of input databases and the possibilities of the first version of software which comprehensively addresses this issue for power circuit breakers with SF_6.
