HENGYI ELECTRIC GROUP Intelligent combina�on low voltage power capacitor 1 General Working in a 0.4kv low voltage network, the intelligent reac�ve compensa�on installa�on (intelligent combina�on type low voltage energy-saving power capacitor) can reduce line power loss, correct power factor, improve power quality, energy-saving device. It combines advanced technologies like modern measurement and control, power electrionics, network communica�on, auto-control, and power capacitor. Compared with tradi�onal reac�ve compensa�on installa�ons, it is smaller, cheaper, more cost-saving, more flexible, more convenient to maintain, with less power consump�on, longer life span and more reliability, matched with demand of smart grid for reac�ve compensa�on. 2 Applicaton The capacitor compensa�on installa�on offers solu�ons to improve power factor and increase power grid efficiency. The main applica�on fields are: Factory power distribution systems Residential area power distribution systems Municipal commercial buildings Tunnel traffic power distribu�on systems Box transformer substa�on, cabinet sets, and outdoor distribu�on boxes HYBAGB )/- I Type (I: dry-type; none: regular) Second capacitor capacity First capacitor capacity Rated capacity Capacitor rated voltage Program code FB: Indicates split phase compensa�on GB: Indicates three phase compensa�on A: Automa�c control B: Design No. Enterprise code 4 Normal working and installa�on condi�ons 4.1 Ambient temperature：-25℃ ~ +55℃ 4.2 Rela�ve humidity：40℃ ≤20%；20℃ ≤90% 4.3 Al�tude：≤2000m 4.4 Environmental condi�ons: no noxious gas and vapour; no conduc�vity or explosive dust; no violent mechnical vibra�on. 5 Main parameters and other condi�ons HYBAFB-35H 35kA high breaking ability type 5.1 Measurement error Voltage：≤±0.5%，Current：≤±0.5%， Ac�ve power：≤±1%，Power factor：≤±1%，Temperature：±1℃ 5.2 Protec�on error Voltage：≤±0.5%，Current：≤±0.5%，Temperature：±1℃ ,Time：±0.1s 5.3 Reac�ve compensa�on parameters Reac�ve compensa�on error：≤Minimum capacitance 50%，Capacitor switching �me can be set between 10s~180s， 5.4 Reliability parameters Control accuracy: 100%，Permissible switching �mes: 1 million， A�enua�on ra�o of capacitance running �me: ≤1% per year， A�enua�on ra�o of capacitance switching: ≤0.1% per 10,000 �mes 5.5 Mains condi�ons: rated voltage：380V±20%; (other rated voltage produc�on on requested)。 Harmonic voltage: Sine wave, with tot
