Dry Type Transformer Capacitor Settings

GNEE Steel three phase dry type transformer

Generally speaking, for the test formulation of dry-type transformers, partial discharge tests are also required. So how to do this test? The following are the common partial discharge steps of dry-type transformer tests for your reference:

The technical solution of the utility model is a dry-type transformer partial discharge test device, which includes a coupling capacitor, a telescopic platform, and a lifting vehicle. The coupling capacitor is arranged on the telescopic platform, and the telescopic platform is fixed on the lifting vehicle. The lift truck is equipped with a hydraulic mechanism, which can be lifted and lowered freely. A self-locking universal wheel is installed under the lift truck, which can be turned or fixed, and can be freely adjusted according to the actual situation. In order to improve work efficiency, improve safety, reliability, and ensure safe distance, three single coupling capacitors are changed into one three-phase coupling capacitor. This meets the needs of the standard and combines three three-phase partial discharge tests into one test, saving nearly 1/3 of the time. By fixing the positions of the three coupling capacitors, the safety distance is reliably guaranteed. This experiment can improve work efficiency and take into account the safe test distance. For high-voltage product tests, only the coupling capacitors on both sides need to be pulled apart to ensure the safe distance, thus ensuring the accuracy of the test and improving the efficiency of the transformer test. The above are the main steps and main test procedures of common dry-type transformer partial discharge tests for your reference.
