PQR

Solution for electric shock prevention between electric car and PSD, and PSD equipment lightning/surge protection

As Is
  1. Carbon grounding rod installed on the concrete floor at the bottom of the platform. Independent ground (TT method)
  2. No system to alleviate rail potential
  3. Potential difference caused by rail potential
  4. Touch voltage due to potential difference
  5. Touch voltage does not meet technical standard
  6. Potential difference between neutral line and ground line
  7. Failure of electrical, communication, power equipment due to lightning/surge inflow caused by potential difference
  8. Difficult to secure safety of passengers
  9. Risk of electrical shock and fire
  10. Need plans to prevent serious disasters
To Be
  1. eca3G TNC-PQR installation TNC method composition
  2. Prevents electric shock and removes Arc (fire hazard)
  3. Controls potential difference between rail-PSD below 2V
  4. Touch voltage meets technical standard
  5. Alleviates potential difference between neutral line and ground line
  6. Prevents electrical, communication, power equipment from lightning and surge through equipotentiality
  7. Secures passenger safety (electric shock, fire)
  8. Establishes plans for serious disasters

Electric shock(prevention of electric shock/arc) disaster and PSD failure prevention solution [Safety]

01. TNC-PQR
Prevents electric shock accidents and equipment failure through perfect common grounding and equipotential system of PSD control system, digital electronic communication equipment, sensor, etc.
  1. Destruction of insulation layer due to deterioration of platform

    Need to minimize rail potential and allowed touch voltage (5V or lower)

  2. Diversification of electric shock environment due to increase of various safety facilities in the platform

    Need to minimize potential difference between different facilities

  3. Increased safety accidents due to increasing aged population

    Secure stable operation environment such as safety footstep/PSD control, etc.

  4. Electric shock elements due to narrow space between structure and electric car

    Satisfy KEC/EN50122/50526 technical standards

  5. Secure stability of various facilities through equipotentiality of underground space

    Reference potential/TN-C common ground composition important KEC/IEC/NEC

eca3G TNC-PQR is specialized in preventing electric shock and securing equipotential environment against various environmental changes
02. TNC-PQR module

Electric shock prevention and PSD facility lightning/surge protection solution
