Abstract

一种干式变压器压钉装置,包括变压器夹板、压钉、锁紧螺母、压钉座及定位螺母,其特征在于,所述压钉安装在变压器夹板的下端,压钉采用螺栓,螺栓头上置,压钉设置在压钉座中与锁紧螺母、定位螺母连接。本实用新型的干式变压器压钉装置,所述变压器的压钉安装在变压器夹板的下端,而压钉采用螺栓,且螺栓头上置,由于螺栓头固定,能避免一旦有机械松动时,锁紧螺母松脱而导致短路事故,安全性能大大提高。

Description

干式变压器压钉装置
技术领域
本实用新型涉及变压器,特别是一种干式变压器压钉装置。
背景技术
现有的干式变压器,其压紧装置均是先通过压钉紧在夹件上,再在压钉上方某处锁紧螺母,这种结构的缺点是,锁紧螺母在夹板上部,处于自由状态,定位能力差;当变压器起吊或受到机械冲击时,夹板自身会产生微量位移,锁紧螺母随之松动,在变压器运行时固有的电磁力作用下,螺母逐渐松脱,严重时还会掉入变压器线圈、铁心内部造成短路事故。
发明内容
本实用新型的目的就是提供一种安全可靠的干式变压器压钉装置。
本实用新型的干式变压器压钉装置,包括变压器夹板、压钉、锁紧螺母、压钉座及定位螺母,其特征在于,所述压钉安装在变压器夹板的下端,压钉采用螺栓,螺栓头上置,压钉设置在压钉座中与锁紧螺母、定位螺母连接。
本实用新型的干式变压器压钉装置,所述变压器的压钉安装在变压器夹板的下端,而压钉采用螺栓,且螺栓头上置,由于螺栓头固定,能避免一旦有机械松动时,锁紧螺母松脱而导致短路事故,安全性能大大提高。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
一种干式变压器压钉装置,包括变压器夹板5、压钉4、锁紧螺母3、压钉座2及定位螺母1,其特征在于,所述压钉4安装在变压器夹板5的下端,压钉4采用螺栓,螺栓头上置,压钉4设置在压钉座2中与锁紧螺母3、定位螺母1连接。
