摘要
介绍了开关变压器和固态晶闸管两种软启动装置的工作原理,针对两种软启动技术应用中的串并联问题和晶闸管高次谐波问题,分析了它们在10 kV系统中的应用效果、应用方案及控制方式,总结出各自的优缺点,以期对今后软启动方式的选择起借鉴作用。
The work principles of switch-transformer and solid-state-thyristor are introduced. It is analyzed that problem of series-parallel connection and higher harmonics effect in two kind of soft start device, the devices of application effect in 10 kV system, the design program and the control pattern. In order to select and put to use the devices properly the advantages and faults of the two are indicated respectively.
