Practice of Using in Series Bypass Line and Line Breaker to Act as a Temporary Bus Coupler Circuit
This paper describes a dual-bus connection with bypass mode converter station, because the interval transformation of the bus coupler can't be long-term use so as to use the bypass and line breaker in series wiring to act as a temporary bus coupler circuit operating experience. It analyzes the differences of the blocking logic and five anti-logic under this particular operation way, and proposing to increase one set of anti-disoperation of microcomputer online detection device and leaving the original five-prevention system, in the inverted logic of bus use temporary blocking anti-program. Accordingly, this paper summarizes the operating personnel in the field-bus operation, meanwhile elaborates the protection configuration and fault analysis of related issues that may occur. Through ten times of use, the practice of using in series bypasses line and line breaker acted as a temporary bus coupler circuit is confirmed as a feasible and reliable way.
