Designing Automatic Syringe Shaker as The Supporting Media for Method of Dissolved Gas Transformer Oil Analysis

摘要

The common concern of an operational power electrical tool utilized to be performing in each thermal and electrical failure. Most of the power transformed generally utilized insulator oil that was once functioning as cooler and to dissolve its dangerous gas in order not to flow independently. Identifying kind and number of gas concentration, that was dissolved in oil may give information concerning the indication of failure that takes place in the electrical tool. The technique for figuring out and analyzing dissolved gasoline in the oil referred to as dissolved gas analysis (DGA). The procedure of oil sampling of testing DGA with a method of Morgan Schaffer was utilizing a syringe. Within the use of a syringe, after taking an oil sample into the syringe so the syringe was extracted to separate elements of dissolved gas. Utilizing the syringe within the process of extraction was not the greatest considering the fact that it had to be manually finished with the method of extraction for each syringe. In this study, it was achieved in making a computerized syringe shaker, that may do an extraction of electrical tool oil to extract dissolved gas within the transformer oil automatically. This study would additionally verify the time associated rate of motion variable to acquire an optimizing syringe shaker. This instrument utilized a DC motor as a driving supply. Based on the data, that was obtained, the proportion of extraction level that was received with the use of computerized syringe shaker electrical tool oil utilized to be smaller in contrast with the manual method and it had an error level of 0.124%. The timer check result of the length of extraction time showed that an error percentage of about 0.004%.
