Abstract : This paper introduces an intelligent measurement and control device suitable for 3~35kV indoor high-voltage switchgear. It is used for primary switchgear status simulation display, high-voltage live indication, anti-condensation temperature and humidity control, electrical parameter measurement, etc., which greatly improves the integration and intelligence of switchgear operation and measurement.

I. Introduction
Switchgear typically includes primary switching equipment such as circuit breakers (load switches), isolating switches, and grounding switches. Monitoring the status of these primary switching devices is crucial during operation and commissioning. Traditional switchgear usually uses indicator lights to indicate these statuses, which is not intuitive and inconvenient for wiring. The intelligent monitoring and control device for switchgear combines the status display of primary equipment with the primary circuit diagram of the switchgear. The LED display is positioned according to the equipment symbols on the primary circuit diagram, making the circuit status clear, vivid, and intuitive, as shown in Figure 1.
Meanwhile, the integrated high-voltage live display, automatic temperature and humidity control, and electrical parameter measurement functions make the switch cabinet panel simple and elegant, reducing the workload of secondary wiring.
