High voltage switches are important equipment in mine power supply systems. With the development of technology, explosion-proof high-voltage vacuum distribution devices are increasingly being used in mine power supply systems, gradually replacing the original oil circuit breakers With the widespread application of explosion-proof high-voltage vacuum distribution equipment, how to improve training effectiveness and efficiency, reduce training time, and adapt to the needs of mine safety production has become an increasingly urgent issue In view of this, the author created a three-dimensional model of the explosion-proof high-voltage vacuum distribution device and completed the connection combination in the virtual substation environment, which has a significant effect on understanding the explosion-proof high-voltage vacuum distribution device and displaying the three-dimensional virtual substation, improving training efficiency and effectiveness
