Background
A current transformer (hereinafter, referred to as CT) is an electric power device that converts a large primary-side current into a small secondary-side current according to the electromagnetic induction principle, and plays an important role in an electric power system.
The economic development is advanced, and the electric power is advanced. In recent years, with the rapid development of local economy, the electricity consumption greatly rises, and the engineering projects of newly building, expanding and overhauling a transformer substation are increasingly increased. The field test workload is increased, and the personnel configuration is not obviously changed, so that the bearing capacity of the team is insufficient, the requirements of testers are reduced, the test time is shortened, and the working efficiency is improved. The main transformer is the core equipment of transformer substation, and transformer rising seat CT is used for the measurement and the protection of main transformer, plays vital role. The CT connection test comprises insulation, direct resistance, transformation ratio and polarity tests, and the protection winding needs excitation characteristic tests.
The transformer lifting seat CT is a straight-through type CT, after being installed, a sleeve pipe penetrates through the head end and the tail end of the lifting seat, and a sleeve pipe lead is used as a primary winding of the lifting seat CT. Therefore, the transformation ratio polarity test requires that a test line of the instrument run through the elevated CT. The manufacturer generally fills nitrogen to transport the lifting seat CT, and the upper opening and the lower opening of the lifting seat CT are sealed by cover plates after the lifting seat CT arrives at the site. The traditional test method comprises the following steps: open the CT upper cover, use the crow bar to strike CT lower cover, get rid of the paint of lower cover portion, guarantee that the crow bar contacts well with the lower cover, and test instrument P1, P2 connect crow bar, CT body bolt respectively, and the crow bar acts as primary winding promptly.
