【摘要】 根据国内外有关SF6断路器故障统计和事故分析,提出SF6断路器故障模式和辨识指标,旨在改变断路器传统的定期检修方式。按照本文提出的故障模式和辨识指标,对SF6断路器进行在线监测,可实现“按状态检修”或“以可靠性为中心检修”的先进检修模式,有利于提高SF6断路器的可靠性,避免危及系统安全的严重事故发生,降低断路器检修维护费用。更多还原

【Abstract】 According to fault statistics and accident analyses about SF₆ circuit breakers at home and abroad,the fault pattern and identification indices of SF₆ circuit breakers are presented,so as to change the conventional periodic maintenance mode of circuit breakers.Using the proposed fault pattern and identification indices in on-line monitoring of SF₆ circuit breakers,advanced modes of condition-based maintenance or reliability centered maintenance can be realized,which helps to improve the reliability of SF₆ circuit breakers,avoid the occurrence of serious accidents that endanger the system,and lower the costs of circuit breaker maintenance.更多还原
