Abstract: The importance of high and low voltage switchgear in the current power system is self-evident. In order to better teach the students of related majors in universities across the country, taking the high and low voltage switch cabinets of Chaozhou 10kV power distribution station as an example, 3ds Max software is used to model the equipment in the main control room. Using Unity3D and C# script language, the development of immersive high and low voltage switchgear teaching software based on virtual reality is completed. Practice has proved that this teaching method can enable college students to deeply understand the safe operation steps of high and low voltage switch cabinets in a realistic virtual teaching environment, and finally achieve good teaching results.
