杭州电讯电器厂最近研制成功J D—1型交流电焊机空载节电器。该装置能在电焊机空载时自动切换开关达到节电的效果。该节电器主要是利用电焊机工作状态与空载时电压的不同,通过少量电子元件的工作,使稳压管二端经常保持一个稳定的直流电压,并使二极管导通与断路来操纵继电器的吸、放动作,这样,电焊机初载电流明显下降,减少了无用功的消耗,从而达到节电的目的。该装置是该厂在分析国内同类产品的基
Hangzhou Telecom recently developed electrical plant J D-1-type AC welder no-load saver. The device can automatically switch the switch when the welder is idle to save energy. The Saver is mainly the use of welding machine working state and no-load voltage is different through a small amount of work of electronic components, so that both ends of the regulator often maintain a stable DC voltage, and the diode conduction and open circuit to manipulate the relay Suction, release action, so that the initial load current welding decreased significantly to reduce the useless power consumption, so as to achieve the purpose of saving. The plant is the plant in the analysis of similar products based
