一种低涡流损耗消磁器
本技术属于磁屏蔽装置消磁
,具体涉及一种低涡流损耗消磁器。
技术介绍
消磁器主要由三部分组成,包括初级线圈、次级线圈和消磁线圈,从功能上讲主要包括外壳磁路、内部铁芯及缠绕在铁芯外面的线圈。当给缠绕在铁芯外部的线圈通220V交流电时,在线圈中会产生50Hz的交流磁场,其中磁芯的主要作用就是增加磁场强度。在现有的消磁器产品中,磁芯材料用的是由碳钢材料,其形状是棒状,为了减少涡流,在碳钢棒上开有三个通体槽,但由于碳钢棒的特殊物理特性,在给消磁器通电一分多钟后,碳钢棒会严重发热,用手触摸有烫手的感觉。发热的碳钢棒使消磁器不能连续多次使用,过热会破坏铜线的绝缘层,造成短路,带来极大的危险。专利文献中曾公开了一种连续式退磁器,包括底座,底座上安装有一输送带,该输送带上方设置有一门形退磁器,输送带穿过该门形退磁器,门形退磁器两侧边通过定位螺钉固定安装在输送带的两侧,底座上还安装有传动电机,该传动电机通过传动皮带与输送带连接。其中所述门形退磁器为硅钢片线圈组件。该专利在输送带上安装了由硅钢片线圈组件制成的门形退磁器,能够起到退磁的作用。但其没有公开硅钢片的叠加排列形式。硅钢片的叠加结构不同,所产生的磁场磁场强度和磁场力的方向也是不同的。再者,该种退磁器在通电后噪音较高。
