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。
