为工业应用 环氧树脂 整流器

型号zlsc (B)系列基本参数高压绕组低压绕组“额定容量(kVA)”30~160030~1600“额定工作电压(kV)”6~20个定制“短路阻抗(%)”4 ~ 6“频率(赫兹)”50/60“冷却方式”AN或AN/AF“绝缘等级”F/H“重量kg”—“功能”线圈采用环氧树脂浇注，阻燃性能达到标准V0，具有阻燃、无粉尘积聚、防潮、机械性能好、机械强度强、抗短路能力好等特点。2.对高压、低压线圈进行真空浇注。浇注后采用高压停顿工艺，使浇注树脂更加致密，消除线圈内残留气泡，每套产品局部放电小于5%。3.如果整体结构为pyknic型，且重心较低，则可降低噪声;铁芯采用优质冷轧晶粒取向硅钢片，板宽分布均匀，无波，单位损耗低。 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
