LC compensation unit DTC DTL
Overview

DTLC type reactive power compensation and filter unit is specially designed for reactive power compensation and filtering of distribution systems containing harmonics, which is composed of DTC filter capacitor, DTL filter reactor and thyristor switching switch, which is easy to install and use. DTLC is used in low-voltage reactive power compensation cabinet, effectively avoiding capacitor amplification harmonics, ensuring the safe and stable operation of reactive power compensation system, long service life, low power consumption and high reliability.

Technical characteristics
  • Switching switch: using thyristor or contactor switching technology, stable operation, safe and reliable;

  • L-C filter bank: a variety of combinations, 5%, 7%, 13%, 14%;

  • The capacitor adopts vacuum impregnated, flame retardant, explosion-proof, self-healing, filter capacitor;

  • The filter reactor adopts an iron core closed magnetic circuit structure, which does not generate radio frequency interference, and the Q value is ≥ 50.
