摘要
对比分析了4种降压启动方式的原理、特性及应用范围,以及热变电阻、液体电阻降压软启动技术在改善大中型电机启动性能的应用,降低电网的安全风险,最后提出了软启动技术方案应用的考量因素。
This article mainly compares and analyzes the principles, properties of four reduced - voltage - starting modes and their application ranges, and the application of reduced -voltage soft start techniques of heat -variable resistor, liquid resistor in improving the starting performance of large - sized or medium - sized electromotors, so as to reduce the safety risk to the electric fence. At the end, application of technical solution of soft start techniques and the factors to be considered are brought up.
