无产阶级文化大革命以来,我厂在模具制造和特殊零件加工中广泛采用了电火花加工技术,为了扩大电加工使用范围,进一步提高其工艺指标,我们在学习兄弟单位经验的基础上又试制了YB—3型晶体管复式回路脉冲电源电火花穿孔机床。本电源容量较大,因而要选用许多晶体管特别是大功率晶体管,管子数量多则价钱贵,所以调试人员除需努力使电源达到预期效果外,还需注意防止晶体管损坏问题。我们经初步调试
Since the Great Proletarian Cultural Revolution, I plant in the mold manufacturing and special parts widely used in EDM processing technology, in order to expand the scope of electrical processing and further improve their technical indicators, we learn from the experience of brothers units and trial of the YB -3 transistor double loop pulse power spark perforation machine. The larger the power capacity, and thus to use many transistors, especially high-power transistors, the number of tubes is expensive, so in addition to debugging personnel to make the power to achieve the desired effect, but also need to be careful to prevent damage to the transistor. We have preliminary debugging
