Description

Technical Field

[0001] The utility model relates to a special operating mechanism for a grounding switch. Background Art

[0002] The grounding switch of a vacuum circuit breaker is a device used for high-voltage circuit protection. Its main function is to ground the circuit when the circuit breaker is open to ensure the safety of the system, especially during maintenance or faults. The grounding switch can be operated manually or electrically to connect the grounding point of the electrical equipment to ensure that it is not energized when the circuit breaker is disconnected. The dedicated operating mechanism of the grounding switch is mainly used to drive the grounding switch to achieve reliable grounding. However, in actual use, several problems were found with the operating mechanism: 1. Due to the use of multi-section connections for installation in the switch cabinet, the multi-section connections are prone to loosening and misalignment, which greatly reduces its operational reliability and poses the risk of misoperation; 2. The existing operating mechanism does not have a position adjustment function and has poor flexibility in use. Improvements and optimizations are being made to address this issue.
