摘　　要：DK7740A型线切割机由于原设计和配置电脑系统以及高频脉冲电源部分多为分立元件,受到当时电器制造技术发展的限制,元件性能差,发热严重,经常造成系统死机和高频脉冲电源不工作,严重影响生产的故障,对DK7740A线切割机电气系统进行改造,通过试验,改造使用效果良好。The original design and configuration of computer system and high frequency pulse power supply parts of DK7740A type wire cutting machine are discrete components, which is limited by the development of electrical appliance manufacturing technology at that time, so component performance is very poor and is seriously heating, the system is often crashed and high frequency pulse power supply does not work usually. These have serious effects on producing. By transforming and testing the electrical system of DK7740A type wire cutting machine, It is found that the using effect is better.
