The intelligent control device for switchgear has powerful functions of temperature and humidity control and safety decision-making. It is suitable for 3-35kV indoor switchgear. It replaces the traditional circuit diagram, temperature and humidity controller, and high-voltage live locking device, and has voice prompts and alarms for preventing errors. The device has an exquisite appearance, which effectively improves the quality of switchgear.
This manual describes the Switch Cabinet Intelligent Control Unit developed by Sanda Electronics. It is designed for 3‑35 kV indoor switchgear and replaces traditional analog control panels with a digital interface that includes temperature‑humidity monitoring, live‑wire indication, voice warnings, and optional RS‑485 communication.
The document covers hardware specifications, wiring diagrams, functional descriptions such as breaker status indication, carriage position, ground‑switch status, energy‑storage display, automatic heating/dehumidification, and safety features like live‑wire lockout and voice prompts. Installation, transportation, and storage guidelines are also provided. This manual is written in Chinese.
