ModelZLSC（B）series Basic Parameter HV winding LV winding " Rated capacity（kVA）"30～160030～1600 " Rated working voltage（kV）"6～20customized " Short-circuit impedance（%）"4～6 " Frequency（Hz)"50/60 " Cooling mode"AN or AN/AF " Insulation Class"F/H " Weight kg"—— " Feature""1.Coil adopts epoxy resin pouring with flame resistance reaching standard V0, having characteristics of flame resistance, non-dust accumulation, good damp proof, good mechanical resistance, strong mechanical strength and good anti-short circuit capability. 2.Conduct vacuum pouring onto high voltage and low voltage coil. Apply high voltage standstill process after pouring, to make poured resin more compact and eliminate the bubbles residual in the coil, thus partial discharge of each set of product shall be lower than 5pC. 3. If the integrated structure is pyknic type and gravity center is lower, it can decrease the noise; Iron core adopts high-quality cold rolled grain oriented silicone steel sheets, with characteristics of well-distributed sheet width, wave-free and low unit loss. Meanwhile, it adopts ladder 5 joint structure and selects acoustical material, to reach better noise reducing effects. 4.Air duct of low voltage coil is honeycomb type, evenly distributed along the circumference. Heat dissipation of coil is even, with good heat dissipation effect. 5.There is metallic shielding between high voltage winding and low voltage winding, to prevent the hazard of over-voltage transmitted to low voltage winding. " Application It is widely applied in static excitation system for hydroelectric power plant and fire power plant. " Operation Experience "20
