一种区域阴极保护及接地系统干扰测试的室内模拟装置
摘要：
本发明是一种区域阴极保护及接地系统干扰测试的室内模拟装置。接参比电极IV(12)的恒电位仪I(1)其正极经中断器II(17)后连阳极I(3)，负极经可调电阻电路后分别接管道(5)、连试片(6)的中断器I(16)和连参比电极I(9)的数据采集器I(20)负端；接参比电极II(10)的恒电位仪II(2)其正极经中断器III(18)后连阳极II(4)，负极分别接管道(5)、罐底板(7)和连参比电极II(10)的数据采集器II(21)通道1负端，并且经中断器IV(19)后分别接连参比电极III(11)的数据采集器II(21)通道2负端和接地系统(8)。本发明能准确测量电位和测试接地系统的干扰、屏蔽效应。
摘要（英）：

The invention relates to an indoor simulating device for regional cathodic protection and grounding system interference tests. Specifically, the positive electrode of a potentiostat I (1) connected to a reference electrode IV (12) is in connection with an anode I (3) through an interrupter II (17), and the negative electrode is in connection with a pipeline (5), an interrupter I (16) of a test piece (6) and the negative terminal of a data collector I (20) of a reference electrode I (9) respectively through adjustable resistance circuits; the positive electrode of a potentiostat II (2) connected to a reference electrode II (10) is in connection with an anode II (4) through an interrupter III (18), the negative electrode is in connection with the pipeline (5), a tank baseboard (7), and the negative terminal of a data collector II (21) channel 1 of a reference electrode II (10) respectively, and is connected to the negative terminal of a data collector II (21) channel 2 of a reference electrode III (11) and a grounding system (8) respectively through an interrupter IV (19). The invention can accurately measure the electric potential as well as test the interference and shielding effects of the grounding systems.
