Description :
GWZB-10 (6) GC mining explosion-proof high-voltage microcomputer protection device is mainly used in underground power distribution systems with AC 50Hz and nominal voltage of 6kV/10kV (also compatible with 3.3kV), providing comprehensive electrical protection for high-voltage equipment such as transformers and motors.
- core purposeIn coal mines and other placesFlammable and explosive industrial environmentIn the middle, asSupporting protection units for high-voltage switchgear or mobile substationsTo achieve rapid detection and tripping protection for faults such as short circuit, overload, phase loss, three-phase imbalance, leakage, overvoltage/undervoltage, locked rotor, and long-term starting.
- Explosion proof characteristics: Adopting[Ex ib] IMining explosion-proof design, suitable for explosive gas environments in Zone 1 and Zone 2 underground.
- Control method: With32-bit microcontroller as the coreEquipped with a spring mechanism (different from the GY type permanent magnet mechanism), it supports local/remote operation, has LCD display, constant value setting, event recording, and RS-485 communication functions.
- typical scenarioMainly used for:High voltage feeder switch and mobile substation high-voltage side in coal mine undergroundTransforming old equipment or installing new systems to replace traditional relay protection, improving selectivity, sensitivity, and intelligence levels.
This device does not directly control the on/off of the circuit, but works in conjunction with a vacuum circuit breaker or load switch, belonging toMonitoring and protecting terminal equipmentNot a primary switch body.
