three phase harmonic filter reactor/CKSG - 1

direct connection type With temperature protection switch type c^lus Ad) © W ® C C€ RoHS PKCThree phase series filter electric reactor (HY121-12) 1. General When CKSG series three phase series filter electric reactor is making capacitive reactive power, it is always affected by harmonic current, switching-on, inrush current and switching overvoltage, causing damage to capacitance and decreasing power factor. Therefore, a three phase filter electric reactor should be added on the front end of the capacitor to suppress and absorb harmonic wave, protect capacitor, avoid the influence caused by harmonic voltage and current and impulse voltage and current, improve power quality and increase system power factor and prolong capacitor life span. 2. Types and meanings CKSG □- □- 7% P K K: With temperature protection switch; No Mark: without P: Connector bar; B: Connection lug Rated reactance ratio x L / x c(%) Rated capacitance of adopted capacitor (kvar) Power distribution system voltage (kV) 1-Dry-type air cooling CKDG: Single phase 3. Main structural features 3.1 The iron-cored and air-immersed products are classified as three phase and single phase. 3.2 The iron core is made of high-quality cold rolled silicon steel plate, which is punched and sheared with highspeed punch and has features like minute burr, regularity and eveness, and neat stacks, ensuring the capacitor run with low temperature rise and low noise. 3.3 The coil employs high-quality insulated wire and is wound with a special machine, featuring advantages as good flatness and beautiful appearance. 3.4 During the installation of electric reactor, all fixures have been anti-corrosion treated, with some key fixtures made of non-magnetic material, and experienced the Pre-dry Vacuum impregnation Heat curing process, which integrates the coil and iron core solidly, greatly reduces the running temperature rise and noise, and effectively increase the quality factor of electric reactor and the effect of harmonic wave reducing. 3.5 The dimensions of electric reactor are designed referring to standard cabinet dimensions, with features like small body, simple connection, and much lesser investment on the cabinet. 4.
