Abstract: The invention relates to an Air Insulated Switchgear featuring a mechanical arrangement for circuit breaker position indication during its travel between TEST, INTERMEDIATE, and SERVICE positions. The assembly, mounted on the circuit breaker cradle (21), includes a racking mechanism operated via a handle that drives a lead screw (12) to move the breaker within the compartment. Interlocks ensure safe operation by restricting movement unless handles are properly engaged. A position indicator on the cradle shows real-time breaker status using defined colors: GREEN for TEST, YELLOW for INTERMEDIATE, and RED for SERVICE. A guide roller (15) and sliding groove enhance smooth movement, ensuring accurate positioning and secure interlocking during operation.
