Function Notes
Dynamic Simulation Diagram:
Based on the user's primary system diagram and voltage level (35KV in yellow, 10KV in dark red, 6KV in blue), a mask is created. The break points (such as circuit breakers, truck positions, grounding switches, energy storage, etc.) are represented by dynamic indication modules to form real-time dynamic indication, providing operators with more intuitive, richer, and more accurate status information. The indication contents are as follows:
■ Circuit Breaker Open Indication ■ Circuit Breaker Close Indication ■ Truck Working Position Indication
■ Truck Test Position Indication ■ Energy Storage Indication ■ Grounding Indication
Anti-misoperation Voice Prompt:
■ When the circuit breaker is neither in the working position nor the test position, the working and test position indicator lights flash simultaneously. If the circuit breaker is in the closed state at this time (red vertical simulation bar lit), a voice prompt "Please open the circuit breaker" will sound until the operator performs the open operation. This prevents the operator from forcibly pushing the truck to the working position while the circuit breaker is closed.
■ When the circuit breaker is neither in the working position nor the test position (working and test position indicator lights flash simultaneously) or is in the working position (working position indicator light lit), if the grounding switch is mistakenly forced closed causing the grounding closed indicator light to turn on, a voice prompt "Please open the grounding switch" will sound.
■ When the above two misoperations occur simultaneously, a voice prompt "Please open the circuit breaker, please open the grounding switch" will sound.
Live Display and Interlock:
■ Live display LED ignition voltage (KV): Rated phase voltage × (0.15～0.65)
■ Forced interlock activation voltage (KV): Below rated phase voltage × 0.65
■ When any one of the three phases is live, the relay in the interlock control part is disconnected, prohibiting the electromagnetic lock from operating; when all three phases are not live simultaneously, the interlock release light turns on, the relay closes, allowing the electromagnetic lock to operate.
Note: Forced interlock control power supply: AC or DC 220V, which can protect the reliable operation of the interlock part. If the control power supply disappears during operation, the interlock contacts will not malfunction, and the locked equipment remains reliably locked.
Temperature and Humidity Digital Display and Control:
Can support 1 to 2 temperature and humidity sensors and output contacts, displaying the on-site temperature and humidity values. Users can set the upper and lower limits for heating/dehumidification output as needed. When the ambient temperature ≥40℃, heating is unconditionally stopped to prevent overheating damage.
Operation Functions/Operation Switches:
■ Remote/Local Operation ■ Open/Close Operation ■ Energy Storage Operation ■ Lighting Operation
RS485 Communication:
Digital communication uses RS485 communication interface and MODBUS communication protocol. Through the RS485 interface, multiple switchgear intelligent operation and display devices can be networked for communication.
Human body sensor probe:
When someone stands in front of the cabinet, the device automatically activates the LCD backlight and provides a voice prompt when powered on; after the operator leaves, it automatically stops.
High-voltage live self-test function:
The high-voltage live self-test button is a self-reset button (non-locking). When the main unit is powered but the three phases are not powered, pressing the self-test switch will light up the three-phase high-voltage indicator lights powered by the internal power supply. The unlocked state switches to the locked state (unlock indicator off), and the electromagnetic lock output relay is disconnected.
Voltage detection/phase sequence detection port:
The control device provides a set of (3-phase) external voltage detection/phase sequence detection ports, which need to be used with a voltage detector/phase sequence tester (purchased separately); if the voltage detector/phase sequence tester is inserted into a certain phase sequence port and ground port of the voltage detection terminal, a display indicates the tested phase sequence is live; if the voltage detector/phase sequence tester is inserted into the same phase sequence port of two control devices' voltage detection/phase sequence ports and there is no display, it indicates the phase sequences are the same.
