Abstract: There are several flaws such as poor reliability, complex wiring, low integration, so it is difficult to ensure safe operation in traditional switch cabinet display device. In view of these, a new display device, which was suitable for 3 to 35 kV high-voltage switch cabinets, was designed. It was used for analog display of primary equipment, high pressure charged display, interlock of cabinet door, temperature and humidity control of preventing condensation inside cabinet. This paper gave the working principle of the display device and the hardware configuration of the circuit design. Practical operation results show that the device has the advantages of simple hardware structure, high integrated level and good reliability with high practicality.
Key words: switch cabinet; switch state; temperature and humidity control; high-voltage charged display
