发明名称 METHOD TO CONTROL CORROSION STATE OF RAILWAY POWER SUPPLY CIRCUIT REINFORCED CONCRETE SUPPORT METAL ASSEMBLIES.
摘要 FIELD: physics, measurements. ^ SUBSTANCE: in compliance with the proposed method, the degree of corrosion-initiated destruction of metal elements in underground parts of the support is determined proceeding from the results of measurements of the dependence of the values of complex resistance of the contact "electrolyte-metal parts" upon the frequency of applied test voltage. The voltage generator with time-variable frequency is connected to the controlled circuit between the rail and the support metal parts. The values of the complex resistance of the contact "electrolyte-metal parts" are measured and compared, by special computer program, to known, obtained earlier, data to make an indirect estimation of corrosion state of the support metal parts. ^ EFFECT: higher reliability of diagnostics and control of corrosion state of rail support underground part. ^ 1 dwg
