Abstract

本实用新型涉及一种接地极组,所述接地极组包括四个钢管以及将钢管水平连接在一起的导线,所述钢管长度为2.5m,直径5cm,导线材料为镀锌扁钢,两个相邻的钢管距离5m。在使用时,将钢管及导线一起埋设于地下,使钢管顶部距离地面至少0.5m,即完成了接地极组的埋设。本实用新型结构合理,成本较低,采用本实用新型结构的接地极组,其电阻约等于土壤电阻率的0.051倍,基本能够满足要求。

Description

接地极组
技术领域
本实用新型涉及一种防雷电的接地装置,具体涉及一种埋设于地下的接地极组。
背景技术
接地极是放置在大地中的导电元件组。提供直流电路的一点与大地之间的低阻通路,有在一定时间内连续通过电流的能力。 主要应用于避雷领域。例如常见的避雷针,都必须在地下预先埋设接地极,从而达到引雷入地,起到避雷的效果。
实用新型内容
本实用新型提供了一种结构合理、用于防雷电的接地极组。
本实用新型是这样实现的:
一种接地极组,其特征在于所述接地极组包括四个钢管以及将钢管水平连接在一起的导线,所述钢管长度为2.5m,直径5cm,导线材料为镀锌扁钢,两个相邻的钢管距离5m。
更进一步的方案是:所述的导线截面规格为40×4mm2 。
在使用时,将钢管及导线一起埋设于地下,使钢管顶部距离地面至少0.5m,即完成了接地极组的埋设。本实用新型结构合理,成本较低,采用本实用新型结构的接地极组,其电阻约等于土壤电阻率的0.051倍,能够满足实际要求。
附图说明
图1为本实用新型结构示意图。
具体实施方式
一种接地极组,包括四个钢管1以及将钢管水平连接在一起的导线2,所述钢管长度为2.5m,直径5cm,导线材料为镀锌扁钢,两个相邻的钢管距离5m。导线截面规格为40×4mm2 。
