Ang GGJ type low-voltage reactive power compensation cabinet mao ang intelligent energy-saving core equipment nga maayo para sa 380V/400V low-voltage distribution systems. Gi-design niini aron masolbaran ang problema sa reactive power loss gikan sa inductive loads. Tungod sa dynamic tracking sa changes sa reactive power sa power grid ug automatic switching sa capacitor banks, mahimo kini nga precise compensation ug gi-widely used sa daghang mga scenario sama sa industrial production, commercial buildings, ug new energy supporting facilities.
Core performance ug technological advantages
Intelligent ug precise compensation: equipped with a microcomputer intelligent controller, supporting three-phase or phase separation mixed compensation mode, real-time monitoring sa power factor ug automatic adjustment, makakapabilin sa taas sa 0.95, reduce reactive power sa more than 60%, significantly reducing line ug transformer losses.
Rapid dynamic response: gamiton ang voltage zero crossing triggering switching technology, response time ≤ 20ms, adapted sa fluctuating loads sama sa motors ug welding machines, switching without inrush current or impact, avoiding equipment damage.
Harmonic control capability: Equipped with a 7%/14% reactance rate reactor, effectively suppresses 3-13 harmonics, resulting sa total harmonic voltage distortion rate of ≤ 5%, compliant sa GB/T14549 standard, ug suitable sa harmonic source scenarios sama sa frequency converters ug photovoltaic inverters.
