110kV备自投与保护装置配合问题的分析和探讨

备自投装置广泛应用于110kV及以下电力系统中，特别是在重要的内桥接线变电站中采用的进线及桥断路器备自投更是普遍，不仅与线路保护装置存在配合，与主变保护、母线保护等也均有联系。在实际应用中应结合现场具体情况．综合考虑备自投与各种保护装置之间的配合或联系，运用好备自投装置的各种功能。

Analysis and Discussion of Coordination Problem of 100 kV Auto Transfer and Protection Devices

The auto transfer devices is widely used in 110kV and other lower voltage power system, especially in the incoming line and bridge circuit breaker of the important bridge connection station. The auto transfer devices should not only coordinate with line protective devices,but also cooperate with main transformer protection and bus protection. In application, we should consider of the practical situation on site, and the relation between auto transfer devices and various protection devices, and then apply various functions of auto transfer device well.
