本文向电焊机生产厂家和电焊机用户推荐一种防触电节电装置,该装置经中国电焊机产品检测中心测试,符合现行防触电装置标准, 达到同类产品先进水平。其原理框图如图所示。合上电源开关K,电焊机进入空载状态,整流电路开始工作,延时电路开始延时,开关执行电路输出信号,继电器吸合,主开关断开,电焊机一次回路经轭流圈,使二次电压下降,进入防触电节电状态,当电焊机重新工作 This article to the welding machine manufacturers and welding machine users recommended a kind of anti-electric shock saving device, the device by the Chinese welding machine product testing center testing, in line with the current anti-electric shock device standards to achieve the advanced level of similar products. The block diagram shown in the figure. Close the power switch K, the welding machine into the no-load state, the rectifier circuit starts to work, the delay circuit starts delay, the switch output signal circuit, the relay pull, the main switch off, Secondary voltage drop, into the anti-shock power-saving state, when the welder to work again
