[0002] Traditional switching is difficult to adapt to the needs of the growth of the power grid. In the past decade, the construction of the power grid has experienced rapid development, the number of substations has increased rapidly, the front-line production tasks have become increasingly heavy, and the contradictions between the number and structure of personnel have become prominent. The traditional operation and maintenance model that relies mainly on manpower is inefficient and has limited improvement capabilities, and it is difficult to adapt to the needs of current power grid work.

[0003] One-button sequential control operation is an advanced switching operation mode that can realize intelligent applications such as operation ticket prefabrication, operation task generation, automatic equipment status judgment, anti-error interlocking intelligent verification, one-button start of operation steps, and automatic sequential execution of operation processes. On the premise of ensuring operational safety, it can effectively reduce operation and power outage time, reduce economic losses and inconvenience caused to production and life, and can also effectively reduce the probability of switching operation errors, thereby reducing the accident rate of the power grid, preventing large-scale power outages, and avoiding severe negative social effects.

[0004] Regarding the installation method of GIS micro switches, State Grid has already had an overall plan in the "Technical Guidelines for One-Button Sequential Control Renovation of Substations", but the State Grid Equipment Department has decided to accelerate the application of the "two substitutions" (remote intelligent inspections replacing on-site routine manual inspections, and one-button sequential control operations replacing conventional switching operations) technical applications for substation operation and maintenance.

[0005] At present, the workload of the one-button sequential control transformation project is heavy, especially for GIS equipment. The design of its "double confirmation" micro switch installation tooling faces problems such as multiple GIS manufacturers and models, high debugging risks, difficult installation, and uneven design processes.
