近日,中电电气自主研发的8000kVA环氧树脂浇注干式12脉波整流变压器成功问世,这标志着中电电气在超大功率整流变压器领域取得里程碑式突破。

六维性能 铸就非凡

中电电气12脉波整流变压器以六大核心技术创新,重构工业电力设备性能标杆。通过突破性结构设计与尖端材料工艺的深度耦合,实现电气性能、安全防护、能效表现的全面跃升。

1、超大容量 精工结构

单机容量达8000kVA以上,制造能力达到新高度。高压多层分段式结构提升电气性能,真空环氧树脂浇注高温固化工艺确保绝缘可靠性;低压铜箔绕制技术大幅提升机械强度,抗形变能力达高端水平;

2、电磁优化 安全屏障

高/低压轴向分裂式布置实现电磁安匝分布最优化,抗短路能力突破性提升,故障保护响应速度提升至毫秒级;

3、极致能效 节能典范 

二次绕组输出电压差<0.2%,降低了二次绕组间的环流,提高输出功率效率;空负载损耗低,效率达到99.2%以上,符合国家节能减排政策,环保性能高;

4、净化谐波 电网卫士

有效消除特定次数的谐波,消谐效果好,减少对电网电能污染;

5、场景配适 成本革新

适用于大功率整流设备,尤其是对谐波控制和功率因数改善有较高要求的场合,节省成本;

6、安全隔离 双重防护

有效实现整流器与电网间的电气隔离,增强整流系统的安全性。

核心突破 驱动未来

这款凝聚尖端技术的“工业动力心脏”,专为驱动关键领域而设计。产品核心部件采用精密的真空浇注工艺,赋予产品卓越的机械强度、出色的防潮防污能力以及优异的阻燃特性,符合高端工业装备对电力纯净度、可靠性的需求。

它将成为有色金属冶炼、制氢等大功率整流设备的可靠伙伴,提供纯净高效的直流电源;为大型轧机、矿井提升机等高端变频传动系统注入高质量动力,保障核心装备稳定运转;同时,也为未来超大规模数据中心/HVDC供电等前沿应用场景,提供高效、可靠供电的创新解决方案。

12脉波整流变压器的背后,是中电电气深厚的电磁计算与仿真设计能力、精密的环氧配方与浇注工艺、完备的超大容量变压器试验验证平台以及对高端工业用户核心需求与行业发展趋势的精准把握。

中电电气始终以核心科技为引擎,持续突破技术边界,赋能工业力量,助力全球客户赢得更广阔的未来!
