Load capacity regulating power transformer produced by us is a new type energy saving distribution transformer, the product has two kinds of rated capacity, the principle is that in the case of uninterrupted power supply, the transformer track the load changers through the intelligent system, automatically change its capacity according to the size of electrical load.It solves the problem that seasonal load variation of 10KV distribution network which cause high loss of transformer, and overcomes the problem that off-load capacity regulating power transformer is manually adjusted capacity under outage conditions to cause difficult operation and maintenance.
◆ After automatically capacity regulating, transformer will be run at reasonable situation.
◆ Through capacity regulating, no-load loss of transformer is comprehensively reduced by 50%-70%, reactive power loss of grid is reduced by more than 20%, and reactive power line loss is reduced by more than 20%.
◆ Switching process of capacity regulating is completed within 20ms-40ms, which could keep the power supply continuity of low side.
1. Be suitable for rural power grid where seasonal load variation is large.
2. Be suitable for urban commercial districts, development zones, industrial zone, etc. where diurnal load variation is significant.
