The invention relates to a reactive power compensator, especially to an anti-
harmonic-wave reactive compensation
capacitor module apparatus. The anti-
harmonic-wave reactive compensation
capacitor module apparatus comprises a breaker module, a
current transformer module. A dynamic noncontact switch module, a reactor module, a
harmonic wave protector module, a switch
signal input terminal module, a compensation
capacitor module and a heat dissipation fan, which are all connected together. Power factors of a
system is increased,
energy consumption is reduced, the
voltage quality of a
power grid is improved, equipment is stabilized to function, the electric quality is improved while the power supplying efficiency of a
power grid is increased, and harmonic
waves generated by a load can be effectively filtered. Therefore, harmonic
waves of a
low voltage distribution network for civil uses are inhibited within a
national standard, harmonic wave currents are prevented from damaging power supplying equipment, and the electric quality of a
low voltage distribution network for civil uses and the safety of the network are improved. Furthermore, the installing space of equipment is effectively saved, the equipment is made to have a concise internal structure and is convenient to maintain, the reactive compensation apparatus is improved in reliability and safety, and maintenance technical difficulties are minimized.
