复合投切的智能低压无功补偿电容器设计

Design of intelligent low-voltage reactive compensation capacitor for compound switching

重点阐述了复合投切开关的结构及内部控制原理,且详细介绍了智能投切控制器的内部结构及软件设计。该智能电容器采用多投切判据的"循环投切"方式以实现快速自动投切,并具有自诊断功能,可自动切除故障电容器。测试结果表明该装置能够达到快速精确补偿的目的。

The structure and internal control principle of complex switching switch are elaborated emphatically. The inter-nal structure and software design of the intelligent switching controller are introduced in detail. The intelligent capacitor has a self-diagnostic function and can automatically remove failure capacitors. In the intelligent capacitor,the ＂cycle switching＂ mode of multi-switching criterion is adopted for fast automatic switching. The test result shows that the device can achieve the purpose of fast and accurate compensation.
