Description :
GWZB-10 (6) GY is a mining explosion-proof high-voltage microcomputer comprehensive protection device, mainly used for intelligent protection and monitoring of transformer or feeder line faults such as overload, short circuit, phase failure, undervoltage, overvoltage, imbalance, and grounding on the high-voltage side of 10kV or 6kV mobile substations (transformers) in coal mines.
- Applicable toRated voltage 10 (6) kV, rated current ≤ 630AThree phase neutral point ungrounded power supply system;
- HavingSupporting functions of permanent magnet mechanismIt is often integrated with high-voltage vacuum switches (such as PBG type) to achieve rapid tripping and fault memory;
- The explosion-proof type isMining explosion-proof type (Ex d I)Meet the requirements for use in explosive gas environments in coal mines;
- SupportReal time display of current/voltage, identification of fault types, RS485 communication (optional), and expansion of methane detection interface；
- The suffix 'GY' usually refers toPermanent magnet machine configurationDifferent from the "GC" (spring mechanism type), it is specifically designed for the high-voltage side protection of permanent magnet vacuum circuit breakers.
This device does not directly control the load, but serves asIntelligent protection core unit of mobile high-voltage switchgearTo ensure the safety of the underground power supply system and prevent accidents such as fires and gas explosions caused by electrical faults.
