Kabinet ng mababang tensyon na reaktibong kompensasyon na GGJ

Ang GGJ type low-voltage reactive power compensation cabinet ay isang intelligent na energy-saving core equipment na angkop para sa 380V/400V low-voltage distribution systems. Ito ay disenyo upang solusyon sa problema ng reactive power loss na dulot ng inductive loads. Sa pamamagitan ng dynamic tracking ng mga pagbabago sa reactive power sa power grid at automatic switching ng capacitor banks, ito ay nagpapahayag ng precise compensation at malawakang ginagamit sa iba't ibang scenario tulad ng industrial production, commercial buildings, at new energy supporting facilities.
Core performance at technological advantages
Intelligent at precise compensation: equipped with a microcomputer intelligent controller, suportado ang three-phase o phase separation mixed compensation mode, real-time monitoring ng power factor at automatic adjustment, maaaring steadily increase to above 0.95, reduce reactive power by more than 60%, significantly reducing line and transformer losses.
Rapid dynamic response: gumagamit ng voltage zero crossing triggering switching technology, response time ≤ 20ms, adapted sa fluctuating loads tulad ng motors at welding machines, switching without inrush current o impact, avoiding equipment damage.
Harmonic control capability: Equipped with a 7%/14% reactance rate reactor, it effectively suppresses 3-13 harmonics, resulting in a total harmonic voltage distortion rate of ≤ 5%, in compliance with the GB/T14549 standard, at angkop para sa harmonic source scenarios tulad ng frequency converters at photovoltaic inverters.
Comprehensive safety protection: integrating multiple protection functions tulad ng overvoltage, overload, phase loss, at overcompensation. Ang capacitor ay may self-healing design, at ang residual voltage ay bumababa sa below 50V after 1 minute of power outage, ensuring safe at reliable operation.
Flexible adaptation at expansion: The modular structure supports 1-16 control circuits, with compensation capacity covering 60-600kvar. Maaari itong expanded in parallel with multiple cabinets at compatible sa various low-voltage switchgear tulad ng GGD, MNS, GCK, etc., upang matugunan ang mga pangangailangan ng iba't ibang distribution systems.
