摘要
在ZX5系列弧焊电源的可控硅触发电路中,采用光电耦合器和KJ004触发电路,去掉同步变压器,简化了线路,提高了线路的抗干扰能力,解决了双路触发脉冲的对称性,不仅给生产和调试带来了方便,而且也改善了焊接性能。
The photoelectric coupler and KJ004 trigger circuit are used in the SCR trigger circuit of ZX5 series arc welding power sources.The synchronous transformer is replaced and the circuit is simplified.The antijamming capacity of the circuit is improved.The symmetrical characteristic of duplex trigger pulse is solved.The production and debugging are easy, and the welding performance is improved.
