Abstract

The invention provides a grounding network resistance reducing agent detecting device and a grounding network resistance reducing agent detecting system. The device comprises a corrosion rate measuring module, a resistance rate measuring module and a microprocessor, wherein the corrosion rate measuring module and the resistance rate measuring module are both connected to the microprocessor; the corrosion rate measuring module comprises an electrochemical sensor and a current signal acquisition circuit; the corrosion rate measuring module is used for controlling disturbance voltage applied to the electrochemical sensor according to an input instruction, receiving acquired disturbance current of the electrochemical sensor and determining the corrosion rate of the grounding network resistance reducing agent; the resistance rate measuring module comprises four polar plates arranged in parallel and a voltage signal acquisition circuit; the resistance rate measuring module is used for controlling power frequency current applied to the two polar plates on the outer side according to a control instruction, receiving acquired voltage between the two polar plates in the middle and determining the resistance rate of the grounding network resistance reducing agent. The device disclosed by the invention can be used for measuring the corrosion rate of the grounding resistance reducing agent and also can be used for measuring the resistance rate of the grounding resistance reducing agent, thus the use of the resistance reducing agent of which the corrosion rate exceeds the standard is avoided, and the resistance reduction effect of the resistance reducing agent is guaranteed.

Description

technical field [0001] The present invention relates to ground grid detection technology, specifically a ground grid resistance reducing agent detection device and system. Background technique [0002] The corrosion rate and resistivity of the grounding grid resistance reducing agent are its important performance parameters. DL / T380-2010 (the People's Republic of China Electric Power Industry Standard "Technical Conditions for Grounding Resistance Reducing Materials") stipulates: the corrosion rate of the grounding resistance reducing agent to the grounding body , which is less than the corrosion rate of the corresponding soil to the grounding body. For hot-dip galvanized round steel and flat steel, the average annual surface corrosion rate should not be greater than 0.03mm / a. For non-galvanized round steel and flat steel, the annual average surface corrosion rate Should not be greater than 0.05mm / a. The corrosion rate of the resistance reducing agent characterizes its corr...
