在焊接大型受压容器或焊接罐体的内缝时,焊接工人在容器内一面进行手工焊接,一面操纵旋转容器的转动滚车按扭。该按扭电压380伏,一旦漏电将危及电焊工人的安全。为此我们革新成功罐内焊接防触电的安全装置。其原理是将转动罐体的转动滚车按扭的电压380伏通过变压而降到36伏(如图)。 When welding a large pressure vessel or welding tank, the welder performs manual welding on the inside of the vessel while manipulating the rotating car’s turning button on the rotating vessel. The button voltage of 380 volts, once the leakage will endanger the safety of welders. To this end, we succeeded in reforming the tank anti-shock welding safety devices. The principle is to rotate the cans of the rolling car button voltage 380 V by transformer and down to 36 volts (pictured).
