HIGH-VOLTAGE INDUCTANCE COIL Russian patent published in 2015 - IPC H01F27/14 

FIELD: electricity.

SUBSTANCE: high-voltage inductance coil consists of interconnected coaxial sections wound by band copper. The sections are placed in series with a gap at the frame made as a perforated cylinder with radial rails joined to it. The frame is fixed in a cylindrical tank, which head and bottom are covered by covers. At the tank head there is a coaxial expander with oil level indicator. At the expander there is an oil volume change compensator. Under the bottom cover at least three supports are fixed symmetrically in regard to the centre, each support is made of two parallel planks lying in axially symmetrical planes and protruding behind the tank dimension. Outer ends of the plank at each support are connected by bridges with formation of a gap between the outer tank surface and bridge. In the head and bottom parts of the tank lateral side there are installed ball valves and brass conjoint bushings, which are connected to free ends of the coil respectively. All design elements of high-voltage inductance coil are made of electric insulating materials.

EFFECT: providing protection from influence of outer electroconductive objects.
