一、主回路 1、概述; 毛主席教导我们:“客观现实世界的变化运动永远没有完结,人们在实战中对于真理的认识也就永远没有完结。”我反对于无变压器的可控硅等离子切割电源的试制成功,给了等离子喷涂采用无变器的电源提供了有利条件。原等离子切割电源系三相桥式丰控线路,试制成功以后经过去粗取精,去伪存真,由此及彼,由表及里的分析认为丰波线路串联电阻也是可
First, the main circuit 1, an overview; Chairman Mao teaches us: “The objective real world changes in the movement will never end, and people’s understanding of truth in the actual battle will never end.” I oppose the transformerless thyristor plasma cutting The successful trial production of the power supply provided favorable conditions for plasma spraying using a power supply without a transformer. The original plasma cutting power supply is a three-phase bridge type Fengcheng control line. After successful trial production, it is roughed and refined, and the pseudo-preservation is true. From the analysis of the table and the inside, the series resistance of the Fengbo line is also acceptable.
