HYSPC Three phase unbalance automatic adjusting device 1 Brief introduction and schematic diagram of the automatic adjustment effect It is very common for three phase unbalance in the low voltage distribution. In the urban network and agricultural network,due to a large number of single-phase load, and it is extremely serious for three phase current unbalance phenomenon. The current unbalance in the power grid will increase the consumption of lines and transformer, lowering the function of transformer, affecting the safe operation of transformer, as well as zero drift, which may lead to three phase voltage unbalance, thus to lower the power supply quality. For the above mentioned condition, in order to optimize the power quality, saving energy and reducing emission, we has specially designed three phase unbalance automatic adjusting device. This device can filter more than 90% of the zero sequence in the rated capacity, and control the three phase unbalance degree within 10%. Schematic diagram of the automatic adjustment effect of HYSPC three phase unbalance -►Load Current Transformer - S2 quick response and instant management Imported 100A from phase B, respectively transferred 50A to phase A and phase C, making output balance for phase A, phase B and phase C of the transformer, thus to avoid the power quality problems. a. Effectively avoid partly heating and aging for the middle lines, even the risk of fire. b. Effectively equipment error alarming caused by partly voltage unbalance c. Effectively avoid the risk of systemic weak electric equipment burnt caused by high zero ground voltage. d. Will not increase the active power consumption 2 Model and meanings HY SPC 100 / 400 - 4 - W Outdoors 4:Three phase four wire 3:Three phase three wire Voltage grade: 400V Capacity: 35kvarN 50kvarN 75kvarN 100kvar Three phase unbalance adjustment Corporate code 3.2 Relative humidity: : 5%— 95% without condensation. 3.3 Altitude: <1500m, between 1500 — 4000m, according to GB/T3859.2, the power will be lowered by 1% when adding 100m. 3.4 Environmental conditions: no harmful gas and steam, no conductive or explosive dust, no violent mechanical vibration 3.5 Outdoor installation: space of at least 15cm should be retained in the upper and lower outlet of the module, and space of at least60cm shall be reserved in the front and backof the cabinet to facilitate maintenance.
