Abstract

一种低噪声电力电容器，它包括电力电容器和吸音元件，其特征是在电容器心组底部设置有吸音元件，在电容器心组与箱盖之间安装了限位块，本实用新型的优点是，结构简单，操作方便，降低噪音效果好。

Description

低噪声电力电容器
技术领域                                                       
本实用新型涉及电力设备技术领域，特别是一种低噪声电力电容器。
背景技术
当电容器加上交流电压时，在电容器介质内的电极间将有静电力的作用产生，从而使电容器内部的元件产生振动，这种元件的振动将传给外壳，并使箱壁振动形成噪音，再从外壳辐射出去，这种噪声从传播性质上属于纵波，即电容器的噪声主要是沿着箱底和出线套管方向传播，与噪声测试结果相吻合，根据电容器噪声测试结果来看，电容器底部噪声比其他面严重，现有的电力电容器没有降低底部噪声的措失。
发明内容
本实用新型的目的是提供一种能降低电力电容器的噪音，使之满足国家的标准及国网公司技术规范要求的低噪声电力电容器。
本实用新型是这样实现的，它包括电力电容器和吸音元件，其特征是在电容器心组底部设置有吸音元件，在电容器心组与箱盖之间安装了限位块。
本实用新型的优点是，结构简单，操作方便，降低噪音效果好。
附图说明
以下结合附图对本实用新型做进一步的说明
图1是低噪声电力电容器结构示意图，
图2是图1的局部放大示意图。
具体实施方式
如图1—2所示，该低噪声电力电容器包括电力电容器1、吸音元件2、电容器心组3、箱盖4和限位块5，在电容器心组3底部设置有吸音元件2，在电容器心组3与箱盖4之间安装了限位块5，吸音元件2采用聚丙烯薄膜材料在专用卷制机上卷制，限位块5能有效的固定了电容器心组，减弱了电容器心组的震动。通过电容器噪声测试，箱底的噪音降低3~4dB。
