Capacitors of voltage dividers, capacitive voltage dividers

 Capacitors of voltage dividers, capacitive voltage dividers
Capacitors of voltage dividers is designed for:
* for voltage dividers in AC electrical plants; ** for voltage dividers in different apparatus at AC high-voltage electricity transmission lines, also for air circuit-breaker; *** for voltage dividers for SF6 switches.

         Capacitors of voltage dividers 

          In capacitors designation the first number after type is rated voltage in kV, second – rated capacitance in nanofarad.

          DMR – new designation of earlier produced capacitors DMRU. DMKP and DMKF – capacitors in reinforced polymer or porcelain insulator.

          Capacitive voltage dividers is designed to complete capacitive voltage transformers of voltage classes 110, 220, 330, 500, 750 kV and to secure high-frequency communication from 24 up 1000 kHz along AC electricity transmission lines of frequency 50 Hz.

          Intermediate voltage for DOCI of all voltage classes - 12,064 kV.
          Capacitive voltage dividers are completed with capacitors CMAOI -1103 (1663,1883) and CMAI-1103 (1663, 1883).
          Dividers for voltage 500 and 750 kV are equipped with electrostatic screen.
Symbol structure part type of dividers decryption follows is:

 
          Symbol structure part type of dividers decryption follows is:
                      DOCI-110 UHL1 D - voltage dividers; O - function - power takeoff; C - communications; I - metering circuit; 110 - voltage type, kV; UHL - climatic modification; 1 - placement category.

            1) - Depending on the performance of the tires, there may be differences in the overall and mounting dimensions of the dividers. The required dimensions are specified when ordering.

          DOCI - voltage divider for power take-off, for communication, for measuring devices.

          DЕО - voltage divider capacitive for optical transformers.
