Permanent magnet energy saving:
The permanent magnet vacuum circuit breaker is adopted and installed in the main cavity with current transformer, transformer and other components. The protector and control circuit components are instaled on the front door control panel. The main circuit is separated from thecontrol circuit. The components are highly interchangeable and easy to install and maintain.
Intelligent Protection:
The advanced microcomputer intelligent protector is adopted, which has mutiple protection and electric metering functions such as overload short circuit, leakage, selective leakage, undervoltage, overvoltage, three-phase imbalance, gas locking, wind power locking, temperature protection, voltage monitoring of opening and closing circuit, vacuum tube leakage monitoring, etc.
Color Display:
Full-Chinese LCD color display screen, dynamic startup screen, which can monitor and display the current circuit voltage, three-phase curent, fault type, parameter and time in real time, and have faut memory ang query function.
Four Remote Function:
The parameter setting can be set locally by pressing the button on the side of the main switch and each branch switch screen, or through the centralized control button on the side of the centralized control panel, or can be set remotely by RS-485 interface, or Ethernet optical fiber (optional) and communication with the upper computer of the monitoring system. The remote star and stop can realize the "four remote" function to achieve unattended substation.
Quick-opening mechanism:
The shell adopts the patented screw door opening mechanism, and is equipped with reliable mechanical interlocking, electrical locking, manual tripping and other devices.
Safety Module:
The external control circuit adopts intrinsically safe and safe module, which is more safe and reliable.
Explosion-proof grade:
Explosion-proof type: Exd I Mb Protection grade: IP54
