Abstract: Taking the geoelectric field observation data of Yuanmou Julin of Chuxiong Earthquake Monitoring Center Station as the research object, combined with the ideas and specific contents of the two transformations since the geoelectric field observation, the observation data curve variation characteristics and data quality in three time periods before and after the two transformations are compared and analyzed, and the following experience is obtained, which can be used as a reference for the transformation and construction of other geoelectric field observation stations: ①the anti-interference ability and stability of solid non-polarized electrodes far exceed lead electrodes; ②Electrode buried depth need to consider more consistent soil electrical properties rather than pay attention to the buried depth, should do a good job in the construction of the site geological prospecting work, to ensure that the electrode buried after the grounding resistance without a big gap, but also should pay attention to the electrode lead buried depth must be greater than the farmers daily farming may touch the depth; ③Double “L” type pole arrangement needs to be strictly in accordance with the construction specifications of the geoelectric station to arrange the long and short pole spacing; ④For the insulation problem of overhead lines, it can be done between the hoop and the pole first through the insulation rubber pad insulation, and then between the hoop and the steel strand through the insulator re-insulating, especially the ground resistivity with the site observation station, more attention should be paid to the insulation of the steel strand.
