Embodiment Construction

[0013] Refer to the following figure 1 In the figure, 100: grounding wire, 101a vertical wire, 101b: horizontal wire, 101c: branch wire, 102: conductive cement, 103a: underground heat-shrinkable insulation layer, 103b: ground heat-shrinkable Insulation layer, 200: auxiliary anode, 300: reference electrode, 400: potentiostatic controller, 401: monitor, 500: photovoltaic power supply, 501: photovoltaic module, 502: photovoltaic controller, 503: photosensitive switch, 504: battery .

[0014] As mentioned earlier, galvanic corrosion is the main cause of corrosion of grounding devices. Electrochemical corrosion is mainly related to the concentration of oxides in the electrolyte (in the soil). The greater the concentration of H+ and O2 in the electrolyte solution, the faster the electrochemical corrosion rate. The grounding wire is buried underground, and the service life of the grounding wire will be reduced due to electrochemical corrosion. figure 1 It is an implementation exam...

Abstract

Belonging to the field of power transmission and transformation, the invention relates to an anticorrosion device and anticorrosion method of a ground wire. The anticorrosion device comprises a ground lead, the periphery of the ground lead's vertical lead is covered with an insulating layer, the periphery of a horizontal lead and the peripheries of branch leads are covered with a conductive cement layer, the ground lead is provided with the negative pole of an additional direct current power supply, the additional direct current power supply is photovoltaic power generation component, the positive pole of the additional direct current power supply is connected to an auxiliary electrode, the ground lead is connected to a sensor, the sensor is in connection with a ground monitor, and the monitor is also connected to a reference electrode. According to the invention, the corrosion degree of the ground wire is alleviated, the corrosion resistance of the ground wire is improved, and the service life of the ground wire is prolonged.

Description

technical field [0001] The invention relates to an anti-corrosion device and an anti-corrosion method, in particular to an anti-corrosion device and an anti-corrosion method for a ground wire, belonging to the field of power transmission and transformation. Background technique [0002] The grounding used for electrical equipment includes working grounding, lightning protection grounding, protective grounding, etc. It is an important measure to ensure the safety of people, equipment and the safety of the entire electrical equipment system. It will lead to building fire, casualties, and even chain accidents, such as gas leakage and secondary fires, equipment power outages and personnel injuries, etc. Poor connection on the roof of the building will cause lightning accidents , especially the grounding network of some transmission and transformation substations. With the increase of transmission and transformation voltage in recent years, the grounding of electrical equipment s...
