Abstract

电抗器内拉杆，包括电抗器的上夹件和下夹件，上夹件上安装上桥板，下夹件下安装下桥板和底座，上夹件与下夹件之间安装铁芯、线圈和线圈浇注体，铁芯与线圈浇注体之间安装绝缘筒，其特征在于所述的铁芯与绝缘筒之间设置固定拉杆，固定拉杆的上端连接上桥板，固定拉杆的下端连接下桥板。与已有安装在电抗器的相与相之间相比，可使电抗器本体左右宽度的尺寸减少10%左右，减少安装电抗器所需的空间，节省包装和运输成本，特别是提高了产品的绝缘水平，减小电抗器相与相之间的磁场干扰，延长电抗器使用寿命。

Description

电抗器内拉杆
技术领域
本实用新型涉及一种电抗器的内拉杆结构，属于电力设备领域。
背景技术
目前，电抗器的固定拉杆都是安装在相与相之间，如电抗器的第一相线圈与第二相线圈之间，第二相线圈与第三相线圈之间，优点是安装方便，装卸容易。但缺点是增大了电抗器的整体（左右）宽度，增加电抗器整体包装和运输成本。同时，由于固定拉杆是金属杆，降低了电抗器相与相之间的绝缘强度。
发明内容
本实用新型的目的是为了克服已有技术的缺点，提供一种将固定拉杆设置在线圈浇注体与铁芯之间，减小电抗器宽度，节省包装和运输成本，特别是提高产品整体绝缘水平的电抗器内拉杆。
本实用新型电抗器内拉杆的技术方案是：包括电抗器的上夹件和下夹件，上夹件上安装上桥板，下夹件下安装下桥板和底座，上夹件与下夹件之间安装铁芯、线圈和线圈浇注体，铁芯与线圈浇注体之间安装绝缘筒，其特征在于所述的铁芯与绝缘筒之间设置固定拉杆，固定拉杆的上端连接上桥板，固定拉杆的下端连接下桥板。
本实用新型的电抗器内拉杆，将固定拉杆设置在铁芯与绝缘筒之间，与已有安装在电抗器的相与相之间相比，可使电抗器本体左右宽度的尺寸减少10%左右，减少安装电抗器所需的空间，节省包装和运输成本，特别是提高了产品的绝缘水平，减小电抗器相与相之间的磁场干扰，延长电抗器使用寿命。
本实用新型的电抗器内拉杆，所述的固定拉杆与上桥板经上螺母固定连接。所述的固定拉杆与下桥板经下螺母固定连接。由螺母固定，连接方便、牢靠。
附图说明
图1是本实用新型的电抗器内拉杆结构示意图；
图2是图1的A—A截面示意图。
具体实施方式
本实用新型涉及一种电抗器内拉杆，如图1、图2所示，包括电抗器的上夹件1和下夹件2，上夹件上安装上桥板3，下夹件下安装下桥板9和底座4，上夹件1与下夹件2之间安装铁芯5、线圈7和线圈浇注体8，铁芯5与线圈浇注体8之间安装绝缘筒6，所述的铁芯5与绝缘筒6之间设置固定拉杆10，固定拉杆10的上端连接上桥板3，固定拉杆10的下端连接下桥板9。本方案将固定拉杆10设置在铁芯5与绝缘筒6之间，与已有安装在电抗器的相与相之间相比，可使电抗器本体左右宽度的尺寸减少10%左右，减少安装电抗器所需的空间，节省包装和运输成本，特别是提高了产品的绝缘水平，减小电抗器相与相之间的磁场干扰，延长电抗器使用寿命。所述的固定拉杆10与上桥板3经上螺母11固定连接，固定拉杆10与下桥板9经下螺母12固定连接，由螺母固定，连接方便、牢靠。
