摘要
首先简要介绍了MFC2000-2型微机厂用电快速切换装置的主要功能、特点及其切换分类,接着重点阐述该装置在满足快速、同期捕捉、残压3种切换条件下的动作原理及实现过程中的注意事项.该装置既能保证厂用电切换的可靠性,又能保证切换速度,解决了以往因断电时间过长,电动机成组自启动电流大,母线电压难以恢复,从而导致自启动困难,甚至被迫停机停炉的安全运行问题.
The function, characteristic and switch sorts of the MFC2000 - 2 microcomputer swift switch device are introduced firstly. The action principle and sticking point of the device in the conditions of swiftness, same - frequency catch and remnant voltage switch are analyzed. Finally, by analyzing the application of the device, the reliability and celerity of the device is verified.
