Claims (1)
面が油またはガスで絶縁される構造であり、気中
では直接試験電圧が印加できず、他巻線より電圧
を印加し誘導法により試験電圧を誘起させる変圧
器において、上記貫通端子の外側を覆うタンクに
端子を接地するための接地装置を、外部より操作
できるように設けたことを特徴とする変圧器の試
験装置。 The outer surface of the through-hole terminal for drawing the end of the winding to the outside is insulated with oil or gas, and the test voltage cannot be directly applied in air, so the test is performed by applying voltage from other windings and using the induction method. A testing device for a transformer that induces voltage, characterized in that a grounding device for grounding the terminal is provided in a tank that covers the outside of the through terminal so that it can be operated from the outside.
