So-called baoding dry type transformer partial discharge, is mainly refers to baoding dry type transformer, transformer, and other high pressure under the action of high voltage electric equipment, internal insulation occurs the phenomenon of discharge, the discharge is only found in the local position of insulation, not immediately to form the whole insulation breakdown or flashover through sex, so become a partial discharge, under normal circumstances, the partial discharge is very weak, rely on intuition, feeling, is not able to detect, must use professional testing method.
The detection method of partial discharge of baoding dry transformer is mainly as follows:
1. Electric measurement.
The characteristic waveform or radio interference degree of discharge is found by using oscillograph or radio interferometer.
2. Ultrasonic measurement.
Discharge detection in the formation of the sound waves, and the sound waves into electrical signals, recorded on magnetic tape were analyzed, and the use of electrical signal and acoustic signal transmission time difference, to arrive at the distance of probe points to the discharge point.
3. Chemical measurement.
The content of various dissolved gases in oil and the law of increase or decrease can be detected by this test method. The composition, proportion and quantity of oil can be found, so as to determine whether there is partial discharge.
In recent years, an on-line partial discharge detector has been developed, which can automatically detect partial discharge in transformer operation. Of course, in order to prevent the partial discharge of baoding dry-type transformer, it is better to overhaul the baoding dry-type transformer regularly and find out the abnormality in time and deal with it.
