摘要
结合保定电网分析了事故情况下220 kV变压器过负荷问题的严重危害,提出了利用微机型自动装置来解决变压器过负荷问题。变压器过负荷联切装置采用了分“多级多轮”联切负荷的解决方案,使装置在动作过程中可以根据变压器实际过负荷的情况分级分轮地切除过负荷部分,从而达到最佳的切负荷的目的。它具有智能化和自适应的特点。
This paper analyzes the serious damage to Baoding power system caused by 220 kV overloaded transformers in system faulty operating conditions and proposes the installation of microcomputer-based automation device to solve this problem. The device for transformer overload cutoff takes valid anti-interference measurements and adopts pairs of structure of CPU on hardware and software design to ensure the reliability of the proposed device. The device also adopts multi-step and multi-order solution so that it can cut off the overload of transformer step by step in an orderly sequence according to the actual situation of overloading progress. This exhibits the intelligent and adaptive nature of the proposed device.
