Background technology
Under dirty wet condition, insulator dielectric intensity can sharply decline, and just likely edge flashing occurs, cause pollution flashover under working voltage.Pollution flashover accident often causes large area, has a power failure for a long time, so that economy is subject to heavy losses.The resistance to pollution flashover ability having multiple behave wherein to use room temperature vulcanized silicone rubber coating (RTV) can significantly improve insulator at insulator surface preventing pollution flashover accident is an effective Flash Decontamination Measurements.RTV coating has good dielectric property, physical characteristics, chemical stability, excellent hydrophobic nature and migration of hydrophobicity thus makes it have good resistance to pollution flashover ability.Just because of the excellent properties that it is many, RTV coating obtains in electric system to be promoted the use of widely.
RTV coating is organic insulation, can be aging gradually in operational process, loses use value.This just needs to detect it timely and accurately, judge degree of aging to carry out overcoating.The method conventional to RTV aging analysis has: infrared spectroscopy, electron microscope scanning analytic approach, thermally stimulated current TSC test, or carry out more intuitive pollution flashover experiment.
Infrared spectroscopy: from the test product acquired by RTV coating insulator surface, obtains the infrared spectrum of coating, observes the infrared peak of curve caused by the vibration of coat inside group.According to the hydrophobic nature of the situation analysis RTV coating surface of group vibration in coating, and judge the degree of aging of RTV coating with this.
Electron microscope scanning is analyzed: the pattern change observing RTV coating surface with SEM (scanning electron microscope) when enlargement factor is 1000 times.Judge the degree of aging of RTV coating accordingly.
Thermally stimulated current TSC tests: TSC test makes sample under a certain temperature T1, add an external electric field to polarize a period of time, under maintenance electric field conditions, rapidly sample is cooled to temperature T2 (T2 < T1), then removes polarized electric field; By sample linear temperature increase in experiment, measure the short-circuit current of external circuit (sample two ends), the curve of this electric current and temperature is the TSC curve of sample.Utilize trapped charge amount and the trap level of TSC curve calculation sample, trapped charge amount per sample and trap level judge the degree of aging of RTV coating.
Pollution flashover is tested: be placed on by sample in specific experimental situation and first make moist to it and record the saturate moisture condition time, carry out withstand voltage experiment after treating saturate moisture condition to sample.Judge whether to meet service requirement according to its resistance to pollution flashover voltage.
Can find out that above detection method step is numerous and diverse, and a small amount of sample can only be extracted detect in the lab and cannot carry out a large amount of detections.Reasonably extract laboratory sample and can make it have certain representativeness, but still may miss some aging serious coating and cause pollution flashover accident.
In sum, to the judgement of RTV coating aging degree need badly a kind of accurate, easy and can realize real-time online detect system.
