I.General description
Parallel capacitor banks are usually used in power system to compensate reactive power and improve power factor. In order to limit the passing current and closing inrush current of capacitor bank caused by higher harmonic current to protect the capacitor banks, series reactor is usually installed on the capacitor bank. ville electric CKS oil type series reactor can work normally and continuously under the voltage peak value of 3 √ 2un terminal and 1.35in rated current, and can also operate continuously under the total current of no more than 35% of the third and fifth harmonic current, and the effective value is 1.2in rated current.
II.Structural features
1.The iron core is made of high-quality silicon steel sheet, wrapped with high-strength glass ribbon, thermally fixed, and fixed with special iron core curing paint, which can effectively reduce the vibration between iron core cakes and reduce the noise.
2.The coil is made of high quality paper wrapped copper wire. In order to ensure the safety and reliability of insulation structure, dot adhesive paper is used to prevent coil winding displacement.
3.The reactor adopts ripple oil tank with fully sealed structure. The thermal expansion and cold contraction of transformer oil are adjusted by the elasticity of ripple plate to ensure internal isolation from air, prolong service life and reduce maintenance.
