HENGYI ELECTRIC GROUP HYSVG Sta�c var generator 1 Brief introduc�on HYSVG Sta�c var generator can detect the loaded current in a real �me through the external current transformer, extrac�ng the reac�ve power contents of the loaded current calculated by the internal DSP, and then control the PWM signal generator to deliver signals to the internal IGBT, which makes the converter bring the reac�ve compensated current, mee�ng the requirement based on the se�ng values and finally realize the purpose of dynamic reac�ve compensa�on. Three phase unbalance compensa�on The switching �mes can be over 10000 �mes per second, with quick response and dynamic compensa�on. Schema�c diagram of compensa�on effect of HYSVG Sta�c var generator Current Transformer Wall mounted module quick response and instant management Analysis of current sampling signal Drawer module(LCD op�onal) Semiconductor emission power The switching �mes can be over 10000 �mes per second, with quick response and dynamic compensa�on. The low power factor can avoid electricity fines, instead of that, it will bring the corresponding reward, thus to release the capacity of the transformer. 2 Model and meanings HY SVG -400V -35kvar / 4L (Drawer module） No: Drawer module, A: Set cabinet type, B:Wall mounted type (op�onal for three types) 4L:Three phase four wire 3L: three phase three wire Capacity: 35kvar (35、50、75 and 100 kvar to be op�onal) Voltage grade: 400V Sta�c var generator Corporate code 3 Normal working condi�on and installa�on condi�on 3.1 Environmental temperature: -10℃ ~ +40℃ 3.2 Rela�ve humidity: ：5％～ 95％ without condensa�on. 3.3 Al�tude: ≤1500m, between 1500 ～ 4000m, according to GB/T3859.2, the power will be lowered by 1% when adding 100m. 3.4 Environmental condi�ons: no harmful gas and steam, no conduc�ve or explosive dust, no violent mechanical vibra�on 4 Systemic parameter 4.1 Rated input line voltage: 400V(-20% ~ +20%) 4.2 Power grid frequency: 50Hz (range: 45Hz ～ 55Hz) 4.3 Power grid structure: three phase three wire, three phase four wire (400V) 4.4 Current transformer: 100/5 ～
