SEGMENTED-CENTRALIZED-TYPE HIGH-DENSITY ELECTRICAL METHOD MEASUREMENT SYSTEM AND APPLICATION THEREOF

摘要

A segmented-centralized-type high-density electrical method measurement system and an application thereof relate to the field of high-density electrical method measurement systems. The system comprises a testing host, a plurality of electrode exchanging devices, cables with taps and electrodes connected to the taps. The testing host and the electrode exchanging devices are connected in series by means of the cables, and the electrode exchanging devices are connected to one another in series by means of the cables; a plurality of cores, divided into bus cores and tap cores connected to the taps, is arranged in the cables. Compared with a centralized-type high-density electrical method measurement system, the segmented-centralized-type high-density electrical method measurement system has the advantages that the number of required cable taps is less, the weight of required cables is light, electrical resistivity tests can be supported while induced polarization tests which are not supported by the centralized-type high-density electrical method measurement system can also be supported, the maximum emission current is large, and rolling tests can be supported; compared with a distributed-type high-density electrical method measurement system, the segmented-centralized-type high-density electrical method measurement system has the advantages that the cable diameter is small, the maximum emission current is large, the weight of the cables is light, cable costs are low, the cables are durable and can be replaced individually, and maintenance costs are low.
