Description

Technical Field

[0001] The invention relates to a combined switch cabinet interlocking mechanism. Background Art

[0002] The main function of the switchgear is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. It is mainly used in various occasions such as power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories and mines, residential areas, high-rise buildings, etc.

[0003] Combined switch cabinets usually include incoming cabinets and outgoing cabinets. In order to ensure reliable power supply and prevent power supply accidents, some customers, for safety reasons, propose that the incoming cabinet should be closed first and the outgoing cabinet should be closed later; the outgoing cabinet should be opened first and the incoming cabinet should be opened later. In order to meet this interlocking requirement, an interlocking device needs to be added to the existing switch cabinets. The existing interlocking structure between combined cabinets is complicated and cumbersome, which is not conducive to maintenance and repair, and reduces the use effect of the structure.
