Introduction to grounding wire
Household electrical appliances may have a certain amount of static electricity on their shells due to poor insulation performance or humid operating environment, which may cause electric shock accidents in severe cases. In order to avoid accidents, a wire can be connected to the metal shell of the appliance, and the other end of the wire can be connected to the ground. Once the appliance leaks electricity, the grounding wire will bring the static electricity to the ground and release it. In addition, it is important for electrical maintenance personnel to use electric soldering irons to solder circuits, sometimes because the electric soldering iron is charged and breaks down and damages the integrated circuit in the appliance. Friends who use computers sometimes ignore the grounding of the main housing. In fact, connecting a ground wire to the main housing of the computer can prevent the occurrence of freezing to a certain extent.
In the power system, the grounding wire is an important tool to ensure that the staff can use it when voltage unexpectedly appears on the equipment and lines that have been powered off. According to the regulations issued by the ministry, the grounding wire must be made of bare copper soft wire of 25mm2 or more. In electrical appliances, the grounding wire is a circuit connected to the outer shell of electrical equipment and other parts to promptly conduct away the inappropriate charge or leakage current generated by various reasons.
Instructions for use:
(1) When hanging the grounding wire: first connect the grounding clamp, then connect the power clamp; when removing the grounding wire, you must first remove the power clamp and then the grounding clamp according to the procedure.
(2) Installation: Fix the double-eye copper nose on the phase-splitting grounding soft copper wire to the corresponding position of the power clamp on the grounding rod (the power clamp is fixed or movable), and fix the single-eye copper nose on the phase-splitting grounding wire to the grounding clamp or ground pin to form a complete set of grounding wires.
(3) Verify whether the voltage level of the grounding rod is consistent with the voltage level of the operating equipment.
(4) The grounding soft copper wire is available in phase-splitting and combined types, and the grounding rod has flat-mouthed and double-spring hook wire clamps.
