Description
Technical Field
The invention belongs to the technical field of high voltage and insulation, and particularly relates to a digital display type dielectric conductivity tester enhancing method and system.
Background
At present, the conductivity index can represent the conductivity of a dielectric medium under a direct-current electric field, and is a basic electrical performance index. The conductivity test is a basic test project in the field of high voltage and insulation technology, and is very important for insulation media and semi-conductive media, whether performance test in the process of developing new materials or performance test of electrical equipment. Accordingly, conductivity measuring instruments have been developed over the years from pointer type measuring instruments to digital display type measuring instruments, and digital electrometer dielectric conductivity measuring instruments have appeared. Digital display conductivity testers are still widely used by highly-skilled, research manufacturers at their relatively low prices compared to digital electrometer conductivity testers.
The current of the dielectric under the action of the dc field, which is influenced by the charging current of the capacitor in the dielectric and the absorbed current, generally decreases with time and finally tends to a certain stable value. Accordingly, the resistance and resistivity values obtained by the test gradually increase and tend to a certain stable value. Due to this feature, the conventional dielectric conductivity tester based on the digital display micro-current meter has the following disadvantages compared to the dielectric conductivity tester using the digital electrometer:
(1) the digital display type conductivity tester displays a single electrical parameter test result at each moment, the display result changes continuously along with time, the result storage cannot be carried out, it is difficult to determine that the electrical parameter test result tends to be stable, and the test result of the conductivity tester of the electrometer can be stored in a computer and an electrical parameter change curve can be made;
(2) the decay time of the current is related to the characteristics, composition, uniformity, etc. of the dielectric material. Decay times from a few minutes to tens of minutes or even longer are possible in different cases. Therefore, a long time is required for conducting the conductivity test, and the digital conductivity tester needs to continuously observe the result change and determine the test termination time by corresponding manpower.
Therefore, it is necessary to improve the digitization and automation level of the digital display type dielectric conductivity tester and reduce the occupation of man-hour.
