ABB V7、V12真空接触器开关电源改造

摘要

针对ABB系列V7,V12型高压真空接触器的宽电压供电模块进行国产化改造方案,由一个ABB专用300 V电源模块由长时间工作改为两个普通电源模块工作,而且改造后的电源模块可安装在启动柜外面,改善了工作环境也方便了时时检测,从而大大延长了整体的使用寿命.%The localization modification scheme for wide voltage range supply module of ABB V7 and V12 HV vacuum con-tactors is proposed in this paper. A special ABB 300 V power supply module which works in a long term was modified to two common power supply modules. The modified power supply modules can be installed outside the control cabinet. The modifica-tion improved the working environment. It is convenient to perform real-time detection, and can prolong the service life of the whole system.
