product introduction:

GKDKType Mine General Power Switch Cabinet and GKY Type Mine General Power Supply Cabinetis widely used in underground and surface applications in non-gas explosion hazardous minesDistribution room, to provide stable DC power supply for power supply and distribution equipment. Mine general type power switch cabinet andmine general power supply cabinet has passed the KA certification of the national safety standard center..

product features:

  1. Fully enclosed metal structure, good sealing performance, anti-corrosion, anti-splash water, dust, suitable for long-term operation in harsh mining environment.
  2. Modular high-frequency switch, high efficiency: high-frequency switching power supply module, N +1 redundant design, hot-swappable module, easy expansion and maintenance, machine efficiency ≥ 90%, energy saving and low consumption.
  3. Automatic intelligent management: equipped with intelligent monitoring system, to achieve automatic charging, floating charge, temperature compensation, battery management, without frequent manual intervention.
  4. power supply is stable and reliable: when AC power is off, the battery is automatically and seamlessly put into operation to ensure uninterrupted power supply for protection, control and trip circuits and meet the power consumption of important loads under accident conditions.
  5. protection function: it has multiple protections such as overvoltage, undervoltage, overcurrent, short circuit, phase loss, battery overcharge and overdischarge, insulation monitoring, grounding alarm, etc., and automatic fault alarm.
  6. Remote monitoring and communication: it supports RS485, Ethernet, Modbus and other communication interfaces, and can be connected to the integrated self-system to realize telemetry, remote signaling, remote control and remote adjustment.
