随着施工管理的不断提高,降低安装成本已成为安装企业的重要内容。本文根据施工现场的实际情况,对交流焊机进行技改,使其在空载时的能耗基本降到零,从而达到提高经济效益的目的。众所周知,大型施工现场交流焊机用量大,作业非连续性,而交流焊机空载时相当于接一个空载变压器,空载的有功损耗约为2%的单机视在功率,无功损耗约为10%的单机视在功率,因此降低空载损耗,是非常必要的,它既可降低施工成本,同时也改善了供电系统的
With the continuous improvement of construction management, reducing installation costs has become an important part of the installation of enterprises. This article according to the actual situation at the construction site, technological transformation of the AC welding machine, so that the energy consumption in the no-load basic reduced to zero, so as to achieve the purpose of improving economic efficiency. As we all know, large-scale construction site AC welder large amount of non-continuous operation, while the AC welder no-load equivalent to a no-load transformer, no-load active loss of about 2% of the single apparent power, reactive loss Is 10% of the single apparent power, so reduce the no-load loss is very necessary, it can reduce construction costs, but also improve the power supply system
