First, the use of
Application of LKSG filter reactor in the reactive power compensation and harmonic control system, filter reactor connected with the capacitor, the physical characteristics of LC resonant impedance, minimum or maximum, the corresponding frequency harmonic voltage and current in power systems were absorbed or blocked, to achieve and maintain optimal harmonic filtering, the value system of the power factor, the the power quality has been significantly improved.
Two, the implementation of standards
10229-1988 GB "reactor"
Three, environmental conditions
1, the ambient temperature of -25 to +45 DEG C; relative humidity is less than or equal to 90%RH.
2, altitude is not more than 2000m.
3, no severe vibration and shock, no inflammable and explosive dangerous goods, no conductive dust.
4, around should have good ventilation conditions, such as installed in the cabinet, should exhaust facilities.
5, temperature resistant grade H grade (180 degrees C) above.
Four, technical indicators
1, can be used for 400V, 660V, 690V and other systems.
2, tuned frequency points: 150Hz, 250Hz, 350Hz, 550Hz and other different frequencies.
3, rated insulation level 3kv/min.
4. The limit temperature rise of each part of the reactor, the winding is not more than 80K, the iron core is not more than 95K.
5, reactor noise is not greater than 45dB.
6. The difference of any two phase reactor is not more than 3%.
7, can be in the power frequency and harmonic more than 1.35 times the rated current under the long-term operation.
Five. Determination of parameters of filter reactor
Filter reactor according to the frequency of harmonic N filter requirements, the user to provide filtering reactor inductance, the current amount of special design.
