摘　　要：本文所介绍的ＷＸＨ—３５型微机短线路光纤纵差保护装置由上海交通大学与许昌继电器研究所联合研制，适用于５００ｋＶ及以下的短距离输电线路。装置配备了光纤纵联差动、三段相间距离和三段接地距离，以及综合重合闸等保护功能。本文主要介绍这套保护装置的原理、构成和动模试验结果。Type WXH-- 35 rnicroprocessor-- baSed short-- line OPtical fibre pilot differential protective device is developed by the shanghaiTraffic University together with Xuchang Relay Research institute and is available for 500kV or less voltage short distance POwertransmission Lines. It has the protective functions such as optical fibre pilot differential protect ion, three -- zone Phase -- t o ac phasedistance, three-- zone earth distance, and combined reclosure. The principle,configuration and dynamic modelling test result of thedevice are presented.
