微波炉变压器变身点焊机

微波炉变压器变身点焊机 微波炉变压器， 此类变压器出故障时多交次级问题，一般为打火漏电。老的微波炉的线圈都是铜的，现在铝的多。这里用铝的不行。 拆去次级线圈(细的那一组) 实测初级空载电流约为4A。 我第一次改造时，拆完了线圈后，直接在上面重绕了点焊的次级。结果发现，通电可以把铁钉烧红，烧断，但就是无法焊在一起。 后来查了资料得知，微波炉变压器为漏磁，(漏磁变压器用于负载急剧变化而又逐步趋于稳定状态的电子设备中，如荧光灯电源、离子泵电源等设备。这一类负载表现为开始工作时阻抗较大，需要较高的瞬间电压;而当稳定工作时，负载阻抗较小，需将负载电流限制在允许值内，以使其能正常工作) 于是，切割机磨掉焊接部位，拆散全部铁芯 原来的EI铁芯，E和I分别各在一侧，E与I间有少量气隙。外面是焊在一起的 attention to improving the quality and efficiency of development and pay more attention to security and reform the people's livelihood, more focus on maintaining social harmony and stability, and promote the development of township economy in a better and faster, create a new normal XX development and lay a more solid foundation for XX build a well-off society. Completed tasks this year, we must always pay special attention to the primary task of development. XX weak economic base, low levels of development, economic construction is the Center, we have to create conditions for faster economic development, accumulating more wealth, better people's lives.

Always grasp the fundamental impetus for reform. We are now "no soldiers behind" many indicators ranked in the bottom of the county from getting bigger.
