Research on Cable Identification Device Based on Voltammetry

本项目拟设计一种基于伏安法的电缆识别装置,在工作点处通过一个可靠性高的交流低压电给待测电缆的电缆铠装层或者电缆芯施加一个交流电0~36 V可调的安全电压,电缆识别装置的信号发送端输出的36 V交流电压黑色线电极侧接在临时接地体上(接地线或者接大地),信号发送端输出的电源红色线电极侧连接导线,导线尾端通过一根微小电压探针插到待测电缆一端的电缆铠装层或者电缆芯,在待测电缆另一端,电缆识别装置的信号接收端通过检测施加在待测电缆铠装层或者电缆芯的36 V交流电压(信号接收装置一端接在临时接地体上,另一端通过微小电压探针插入电缆接口端铠装),通过铠装层电压压降来判断待迁改的电缆。

This project intends to design a device for cable recognition based on voltammetry,at the working point by low﹣voltage electrical to a high reliability of the communication cable armoring layer to add a safe voltage,power supply cathode side joint on the temporary grounding system,the positive side of the end of a wire through a tiny voltage probe into the cable armoring layer,mouth in cable solution by voltage signal receiving device to receive in armored layer of dc voltage(signal receiver on temporary grounding body side,the other end through tiny voltage probe inserted end armoured cable solution),the pressure drop through armoured layer voltage to determine the cable to be moved to change.
