What are the types and functions of

1. Safe Grounding

Safety grounding is to connect the shell of high-voltage equipment to the ground. One is to prevent the accumulation of electric charges on the chassis, and generate electrostatic discharge that endangers the safety of equipment and people. For example, the grounding of the computer case and the tail of the tank truck dragging on the ground are to release the accumulated charge and prevent accidents Second, when the insulation of the equipment is damaged and the case is electrified, the protection action of the power supply is triggered to cut off the power supply, so as to protect the safety of the workers, such as the shell of the refrigerator and rice cooker. Third, it can shield the huge electric field of the equipment and play a protective role, such as the protective fence of civil transformers.

2. Lightning protection grounding

When a power electronic device encounters a lightning strike, whether it is a direct lightning strike or an induction lightning strike, if there is no corresponding protection, the power electronic equipment will be greatly damaged or even scrapped. In order to prevent lightning strikes, we generally install lightning rods at high places (such as roofs and chimney tops) to connect with the ground to prevent the safety of equipment and personnel during lightning strikes. Both safety grounding and lightning protection grounding are intended to provide safe protective measures for electronic power equipment or personnel to protect the safety of equipment and personnel.
