Motor Housing Protection Based On The Copper-clad Grounding Rod Resistance Shunt Principle

To prevent electric shock accidents caused by live motor casing, the motor casing is grounded. That is, the motor casing is connected to the buried device copper rod for earthing with a wire 8ft copper ground rod. When the internal windings and casing of the motor leak or short-circuit, the casing will become live. After the motor casing is grounded, the electricity on the casing will be discharged to the earth through the devices copper bonded rod and copper rod for earthing price. In this case, even if a person touches the motor casing, the human body's negative voltage is far greater than the grounding voltage of devices 1 2 in x 8 ft copper ground rod and 10 foot copper ground rod. Most of the current on the casing will be discharged to the earth through the grounding device, while the current that enters the earth through the human body is very small and will not cause harm to the person.
