BG-6800/A Switchgear Status Comprehensive Display Device

1. Product Overview

The BG-6800/A Switchgear Status Comprehensive Display Device, manufactured by Yixing Xiuyuan Technology Co., Ltd., is a status display and environmental control device designed for 3~35 kV indoor high-voltage switchgear. It integrates primary circuit simulation display, circuit breaker status indication, high-voltage live display and interlock, dual-channel automatic temperature-humidity control, and RS485 communication into one unit. The dynamic panel simulation diagram intuitively shows the operating status of primary equipment inside the switchgear, while automatically monitoring and controlling cabinet temperature and humidity to prevent condensation and overheating damage. With flush mounting and simple wiring, it is an economical solution for switchgear status indication and environmental management.

4. Working Principle & System Composition

4.1 Working Principle

The device acquires auxiliary contact signals from the circuit breaker, disconnectors, and earthing switches, and dynamically displays their open/close status via lights on the panel simulation diagram. It acquires three-phase voltage signals through high-voltage live sensors to drive live indicators and output interlock signals. It continuously monitors cabinet temperature and humidity through two sensors, automatically starting heaters when humidity is excessive or temperature is too low, with manual/auto switching available. All status data can be uploaded to the monitoring system via the RS485 interface.

4.2 Functional Modules

· Simulation Display Module: Acquires auxiliary contacts to dynamically display primary equipment status.

· Live Display Module: Acquires three-phase HV sensor signals, indicates live status and outputs interlock contacts.

· Temp-Humidity Control Module: Dual-channel cabinet temp-humidity monitoring with automatic heater control for anti-condensation.

· Status Indication Module: Service/test position, energy storage, and fault status indication.

· Communication Module: RS485 interface with Modbus protocol for remote status data upload.
