内桥接线操作方式的探讨

Discussion on the operation mode of internal bridge wiring

对于内桥接线方式,正常情况下有多种运行方式,本文重点对内桥接线方式双线双变分列运行方式调整为单线双变并列运行方式或由单线双变并列运行方式调整为双线双变分列运行方式的多种操作方式的步骤及其优缺点进行分析,最终从考虑尽量避免电压互感器二次反充电、避免保护误动、提高倒闸操作效率等因素去选出最优方案。

Connection mode for the bridge,under normal circumstances there are many kinds of operation mode,the essay focuses on the internal bridge connection mode double double variable respectively operation mode adjustment for single double parallel operation mode or by a single double parallel operation mode adjustment to double double variable respectively operation way of multiple operating steps and its advantages and disadvantages are analyzed,Finally,the optimal scheme is selected from factors such as avoiding the secondary reverse charging of the voltage transformer,avoiding protection misoperation,and improving the switching operation efficiency.
