This thesis mainly explores long-distance electric net monitor and control system. In order to practice high-voltage net monitor in coal mines, this system designs a kind of intelligence collectors in accordance with the BGP9L-6G high-voltage distribution switches in mines.
This paper describes the technology characteristic of Vacuum Switch which have been macro on middle-voltage and high-voltage distribution, and introduce the way to resolve some key quality problems on the application and debugging of vacuum switch, such as leaking for vacuum chamber, cooperation of operating device, over-voltage, temperature-rise, etc, which is found in testing of Vacuum Switch.
The task of this text is to monitor the density of killing the arc medium and insulation SF6 gas online in high pressure distribution switches, high pressure distribution equipment, high-power become person who give, high pressure cable, etc. Thus achieve the safe operation of power system and purpose with practical economy.
Communication power monitoring includes high pressure power distribution, transformer, low pressure power distribution, continuous power (UPS), switch power, accumulator, air condition and environment (temperature, humidity, submerge, smog etc.)
