Abstract

电力变压器压力释放阀(2)的防雨问题传统的解决办法是在变压器顶部箱盖上单独设计一个遮雨装置,这样的做法不具有互换性;另外就是体积较大,占用变压器顶部本身就很紧张的空间,因为变压器顶部带高压电部件太多,多占用一份空间就多一份击穿风险。因此,本文介绍了直接在压力释放阀上通过法兰连接方式增加防雨罩(1),这样做体积小巧易于安装,具有互换性。

Description

防雨式电力变压器压力释放阀
技术领域
本实用新型涉及一种专用于电力变压器的辅助装置,特别是一种带防雨罩的压力释放阀。
背景技术
压力释放阀是安装在变压器顶部箱盖上,在变压器出故障时用于释放电力变压器内部压力的装置。变压器一般情况安装在户外的变电站,压力释放阀也就连同变压器暴露在户外自然条件下。由于户外雨淋、雪盖、日照紫外线、强风灰尘等恶劣环境都会造成压力释放阀性能下降继而失效。所以必需对压力释放阀进行遮盖抗候。传统的压力释放阀没有防雨功能,要么压力释放阀暴露在自然气候下,要么是在变压器箱盖上追加防雨装置抵抗气候。在变压器箱盖上追加防雨装置缺点是:一.缺乏互换性;二.结构复杂,占用空间大,难于安装。尤其是斜顶结构箱盖,还影响到变压器顶部别的装置的布置,因为变压器顶部箱盖各种装置本身就多,空间受限。
发明内容
本实用新型提供一种带防雨罩的变压器压力释放阀。在传统压力释放阀基础上增加防雨罩,防雨罩直接安装在压力释放阀的法兰上,能有效遮盖住压力释放阀,防止雨淋等气候的影响,结构简单小巧,空间占用小,具有互换性。
附图说明
图1是本实用新型的结构示意图;
图2是图1上部件1(防雨罩)的侧视图。
具体实施方式
一种电力变压器用防雨式压力释放阀,是由防雨罩(1)和压力释放阀(2)构成。防雨罩(1)的罩体由金属板材下料折弯焊接等工序加工成开口的盒状并留出连接孔,再把铆螺母预先均匀铆接于防雨罩(1)连接孔的周围。防雨罩(1)与压力释放阀(2)用螺栓与铆螺母通过压力释放阀(2)上的法兰连接起来。防雨罩(1)与压力释放阀(2)连成一体。
