一种带电报警型接地线的研究与设计

Research and Design of a Kind of Grounding Line with Power-alarm

为减少装设接地线时人力投入,避免带电装设接地线的恶性操作事故发生,保证人身和设备的安全运行,本文研究与设计一种带电报警型接地线。根据接地线接头间的尺寸,设计了带滤波功能、抗电磁干扰功能的近电感应器,并对其他模块进行选型。试验以及试用结果证明,本装置能可靠的在带电设备安全距离外发出报警信号,并有效减少装设接地线时的人力投入。

In order to reduce the manpower input to install the grounding wire, to avoid the malignant operation accident of installation grounding wire in the case of electricity and to ensure the safe operation of the personal and equipment, this paper studies and designs a kind of ground wire for power-alarm. According to the size of the grounding line joint, a power-alarm with filtering function and anti-electromagnetic interference function is designed, with other modules being matched. The test and the results show that the device can reliably send out alarm signals outside the safe distance of the charged equipment, and effectively reduce the manpower input when the grounding wire is installed.
