HYSPC Three phase unbalance automatic adjusting device 1 Brief introducton and schematc diagram of the automate adjustment effect It is very common for three phase unbalance in the low voltage distributor 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 consumpton of lines and transformer, lowering the functon of transformer, affectng the safe operaton 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 mentoned conditon, in order to optmize the power quality, saving energy and reducing emission, we has specially designed three phase unbalance automatc adjustng 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%. Schematc diagram of the automatc adjustment effect of HYSPC three phase unbalance -►Load Current Transformer — quick response and instant management Imported 100A from phase B, respectvely 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. Effectvely avoid partly heatng and aging for the middle lines, even the risk of fire. b. Effectvely equipment error alarming caused by partly voltage unbalance c. Effectvely avoid the risk of systemic weak electric equipment burnt caused by high zero ground voltage. d. Will not increase the actve power consumpton Outdoors 4:Three phase four wire 3:Three phase three wire Voltage grade: 400V Capacity: 35kvar, 50kvar, 75kvar, 100kvar Three phase unbalance adjustment Corporate code 3.2 Relatve humidity: : 5%~ 95% without condensaton. 3.3 Alttude: <1500m, between 1500 ~ 4000m, according to GB/T3859.2, the power will be lowered by 1% when adding 100m. 3.4 Environmental conditons: no harmful gas and steam, no conductve or explosive dust, no violent mechanical vibraton 3.5 Outdoor installaton: 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.
