保变电气获专利，在电抗器磁屏蔽板与夹件之间建立等电位连接

11月6日，保变电气（600550）的发明专利《一种电抗器铁心磁屏蔽板装置、等电位系统及电抗器》获授权，申请号为CN202210190772.0。

电抗器的磁屏蔽板由硅钢片构成，片间或与夹件之间若存在电位差，会影响装置的电气状态。方案在屏蔽板端面设置半导电带并配合树脂胶、夹件与引线，利用材料自身的导电特性让不同位置趋于等电位。关注点既包括板内硅钢片之间的连接，也包括磁屏蔽板与机械夹件之间是否能可靠维持同一电位。

截至此次授权消息披露时，保变电气今年获得的各类专利授权共62项，比上年同期减少22.5%。在2026年上半年，公司研发投入为4997.7万元，同比增长7.43%。企业知识产权记录中，保定天威保变电气股份有限公司名下可查到2070条专利信息和9条著作权信息。
