摘要
不同型号差动保护装置的动作原理、差动电流和制动电流的计算方法、定值与参数的配置都不相同。针对电抗器差动保护装置P633的比率制动式纵差保护动作特性进行推导和计算,确定试验方法,并根据试验数据判断P633保护装置性能。
Different types of differential protection devices have different action principles,different calculation methods for differential currents and braking currents,and different configuration of setting values and parameters.This paper deduces and calculates the ratio braking-type longitudinal differential protection action characteristics of the protection device P633 of the reactor,determines the test method,and judges the performance of the P633 protection device according to the test data.
