Abstract
The invention relates to the technical field of electric equipment detection, and in particular to a method for detecting and evaluating coating quality of power grid equipment. According to the method, a coating quality evaluation key index: corrosion grade for power grid equipment service environment is added; through deciding the coating evaluation index according to the power grid equipment service environment, the malpractice that the coating quality is evaluated by adoption of a uniform detection evaluation index at present is solved; and by adoption of the method, the power grid equipment corrosion resistance can be enhanced and then the power grid operation risk is reduced.
Description
technical field [0001] The invention relates to the technical field of electric equipment detection, in particular to a method for detecting and evaluating the coating quality of power grid equipment. Background technique [0002] Coating is a solid continuous film obtained by one-time application of paint. It is used for protection, insulation, decoration, etc. The type and state of the paint are usually determined according to the sprayed substrate. It is currently widely used for anti-corrosion of power grid equipment. The acceptance criteria for the coating performance of power grid equipment only require the detection item to be the coating thickness, and the coating thickness is not treated differently according to the degree of corrosion. In addition, it was also found during the actual inspection and test that the parts with poor anti-corrosion effect have a coating resistance value lower than 10 7 Ohms, components with good anti-corrosion effect, the impedance valu...
