摘要
当前,信息化技术全面渗透于工业领域,容量较大的高压变频器被大量生产。与传统的保护模式相比,若对高压变频器灵活开展差动保护,有助于全面优化变频器涉及到的各运行环节与运行步骤,且符合高压电机保护的宗旨。现阶段,多数电厂已着眼于安装新型电机,以高压变频器替换传统变频装置,并有序开展针对各流程的差动保护,以此延长变频器使用年限,缩减企业成本,提升电厂运行效益。
In recent years,information technology is permeating the current industrial field in an all-round way,on the premise of which a large capacity of high-voltage inverter was born.For many power plants at this stage,power plants tend to replace existing frequency converters to ensure that they are orderly converted into high--voltage converters.Compared with the traditional protection mode,if the high voltage inverter can use the differential protection flexibly,it is helpful to optimize all the operation links and operation steps involved in the frequency converter.This measure is in line with the purpose and goal of the,protection of the high voltage motor.Up to now,many power plants are focusing on the installation of a new type of motor, so as to achieve the differential protection in order to improve the normal service life of the frequency converter,reduce the cost of the enterprise and optimize the efficiency of the power plant.
