Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment, and specifically discloses a multi-point grounding device for motor equipment. Background Art

[0002] Grounding of electrical equipment is a necessary equipment in modern industry. The main function of grounding of electrical equipment is to protect electrical equipment and personal safety, and also has the function of lightning protection. There are multiple electrical equipment and instrument equipment on the current motor equipment, which have grounding wires, and multiple grounding wires are connected to one grounding point. Generally speaking, the grounding wires of multiple devices can be connected to the same grounding point to ensure the safe operation of electrical equipment. However, in some specific cases, connecting multiple grounding wires to the same grounding point may cause some problems, such as excessive grounding current. When the grounding current of the equipment is too large, too many grounding wires connected to the same grounding point may cause the grounding potential to rise, and a potential difference may be generated between the equipment through the grounding wire, resulting in current interference or equipment failure. Multi-point grounding may cause electrical equipment to be connected in parallel, increasing the damage rate of electrical equipment. In addition, the fuse or circuit breaker in the circuit may also trip frequently due to changes in the grounding potential, thereby affecting the normal operation of the equipment and losing the protection of the equipment.

[0003] Therefore, it is necessary to develop a multi-point grounding device for motor equipment to overcome the above problems and avoid too many grounding wires affecting the operation of the equipment. Utility Model Content
