A method for making the insulation of a voltage coil of a HV instrument transformer and a device for making the insulation of a voltage coil

摘要

The method according to the invention is characterized by the fact that a top screen (17) is put on the insulated windings of a voltage coil (10), which screen is joined with a conducting bar (18) of a bushing and next the coil and the joint between the voltage coil (10) and the bushing are banded with bands of winding paper (16) in vertical position of the coil (10), by turns on the upper and lower side of the coil surface. The device according to the invention is characterized in that it comprises a crossbar (6) and means for fixing the position of the voltage coil (6) on the crossbar, and the crossbar (6) is fastened to a revolving frame (1) joined with a body (2) and a base (3).
