施工现场电焊机二次触电保护器的重要性

Importance of electric welder secondary elec-touching protecting machinein constructing court

结合焊接事故,分析了安装漏电保护器的电焊机为什么还会发生触电事故的机理,探讨了二次漏电保护器的原理,提出了操作人员应加强检查二次触电保护器,从而保证电焊能正常进行。

Combined with welding accident, it analyses why electric welder happens accidents of elec-touching with a protecting machine, discusses the principle of secondary elec-leaking protecting rriachine, brings forward that the operator should strengthen to check secondary electouching protecting machine, so as to ensure the normal operation of electric welder.
