Cleaned, derusting, dry, weighing and etc. method obtain sample corrosion weight loss rate.The data symbols that the corrosion measurement method obtains
Reality is closed, is the most basic measurement method of grounding body corrosion test, the disadvantage is that the test period is long, reproducibility is poor.Indoor simulation
Test can be divided into simulation scene and accelerated corrosion tests.Grounding body simulation laboratory test can preferably Control experiment condition, test
Period is shorter, is generally impregnated using laboratory or simulates soil and is tested.
It is considered as different corrosion influence factors to the soil correction test of soft graphite earthing material, and comprehensively considers state
Corrodible property under interior several typical soils, using indoor corrosion simulated experiment to the corrosion resistant of soft graphite grounding body and its connector
Erosion characteristic is studied.Currently, not having for ground resistance measurement and accelerated corrosion in soft graphite grounding body laboratory
Experimental rig.
