摘　　要：针对传统的备用电源自投装置不能适应“手拉手”式110 kV网架的需要,对传统的备自投装置的备投逻辑进行改进;并利用光纤传输备投信号,使改进后的备自投装置能满足“手拉手”式网架的需要。In view of the disability of traditional automatic transfer to reserve power source to satisfy the operation requirements on the 110 kV ＂hand-by-hand＂ networks, the original equipments are reformed logically and the transfer signal will be transmitted through optic fiber.
