CW1开关双电源切换回路在实际工程中的应用

Application of CW1 Switch Dual Power Supply Switching Circuit in Practical Engineering

介绍了双电源供电形式和应用场合。分析了进线开关和母线联络开关在双电源自动切换方案中的控制原理。指出了设计时选择带自动控制器的双电源开关,由智能控制器来控制开关的投切,还可以选择具有RS-485通信接口的智能开关来进行远程控制开关的投切,实现高度自动化,这也是今后智能开关柜的发展方向。

Introduction was made to dual power supply＇s power supply form and application situation. Analysis was made to the control principle of line in switch and bus bar switch in dual power supply automatic switching plan, pointing out that while in design to select dual power supply switch with automatic controller, to control the switching of the switch by intelligent controller, also to select intelligent switch with RS-485 communication interface to carry out the switching of remote control switch can achieve high degree automation, which is also the development direction of intelligent switchgear cabinet in the future.
