  1. 一般情况下,选用II类手持式电动机,安装漏电保护器,额定冲击动作电流不大于15mA,额定动作时间小于0.1秒。如果使用I类安全手提电动工具,也必须是零保护。操作人员必须戴绝缘手套、穿绝缘靴或站在绝缘垫上。

  1. Generally, type II hand-held motor is selected and leakage protector is installed. The rated impulse action current is not more than 15A, and the rated action time is less than 0.1 seconds. If you use Class I safe hand-held electric tools, it must also be zero protection. Operators must wear insulating gloves, insulating boots or stand on insulating pads.
  2. 在潮湿的地方或金属框架上操作时,必须选择II类安全手持电动工具,并且必须安装防溅泄漏保护器。严禁使用I类安全手提电动工具。
  2. When operating in wet places or on metal frames, Class II safe hand-held electric tools must be selected and anti-splash and leakage protectors must be installed. It is strictly forbidden to use Class I safe hand-held electric tools.
  3. In narrow places (boilers, metal containers, grooves, pipes, etc.), Class III hand-held power tools with isolation transformers should be used; Class II hand-held power tools must be equipped with anti-splash devices. Install isolation transformer or leakage protector in narrow area.
