车床和电焊机在操作时,必有一部分时间是空载的,这样就必定会浪费一部分电能,并使电网的功率因素降低,同时又不安全。为了更好地节约用电,我市杭州汽车制造厂、杭州制氧机厂、杭州发电设备厂和紫阳轧粉厂等单位,学习了外地经验,积极推广应用电子技术,分别革新成功了车床、电焊机节电装置。该两装置又名车床、电焊机空载自动延时断电装置,它们是分别采用一套简单的电子装置,以使车床在不切削和电焊机不烧电焊时,能在规定时间(一般在几十秒到一分钟)内与
When the lathes and welders are operating, there must be no load for a portion of the time. This will certainly waste part of the electrical energy and reduce the power factor of the power grid. At the same time, it is not safe. In order to save electricity, the city’s Hangzhou Automobile Manufacturing Plant, Hangzhou Oxygen Making Plant, Hangzhou Power Generation Plant, and Ziyang Milling Plant have learned the experience of the field and actively promoted the use of electronic technology. Welder power saving device. The two devices, also known as lathes and welders, are equipped with a set of simple electronic devices to ensure that the lathe can be used at the specified time (in general) when it is not cutting and the electric welder is not welding. Between tens of seconds to one minute)
