HV shunt capacitor is shunt connected with AC power electric system PF (50Hz or 60Hz) equals and above 1kV, which is used to improve the power factor and voltage quality, reduce line loss, and implement the efficiency of power generation and supply.
Main technical data
Capacitor capacitance: 30kvar~800kvar
Variation of capacitor: 0~±5%
Loss angle(tanδ) at rated voltage ≤0.002
Long-term operation at 1.05 times of rated voltage can be allowed and it also can operate at 1.15 times of voltage for less than 30min. every 24hrs.
It can operate at 1.30In steady over-current caused by higher harmonic and steady over-voltage. Steady over-current can be allowed to reach 1.5In for capacitor with extremely plus variation.
It is complying with GB/T11024-2001 hunt capacitor for AC power system of nominal voltage 1KV and aboveand IEC 60871-1:1997 HV shunt capacitor technical condition.
It uses double-piece coarsening polypropylene film to keep good impregnation. Components do edge-fold convex structure to reduce partial discharge and improve polarity board insulation’s electric field distribution.
Crimping high-strength porcelain bushing with high hermetically sealed performance is applied to capacitor bushing. The welding between bushing and case is with argon arc welding with higher mechanical strength and hermetically sealed characteristics.
Case is made of stainless steel plate, treated through shot blasting and then painting by robots. Surfaces are beautiful with strong anti-corrosion feature.
High reliable inner fuse , good ampere-time characteristics and reliable action.
