摘要
介绍KGPS-250型中频电源的几个故障检修实例。它的控制电路由MCS-51型单片机的整流控制板、逆变控制板以及保护板组成。其故障包括中频电压互感器损坏、控制板的器件损坏、中频炉体线圈接地、水冷电缆折断、反向等。
The KGPS -250 intermediate frequency power source several trouble shooting example is introduced. Its control circuit by the MCS -51 monolithic integrated circuit rectification control panel, the contravariant control panel as well as the fender is composed. Its the breakdown including intermediate frequency voltage transformer damage, control panel component damage, intermediate frequency furnace body coil earth, water cooling cable breakdown, reverse and so on.
