FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering, to transformers, and can be used in ignition systems of vehicles. A transformer (10) comprises a core (12), primary (14) and secondary (16) windings. The core comprises a lengthy core (13), having the main axis (15), and multiple segments (from 12.1 to 12.n-1) from magnetic material, which are arranged along the main axis (15), alternating with gaps (from 18.1 to 18.n-1). Direction of the main axis (15) in parallel to the direction of the magnetic field in the core (13). Each gap that separates linear segments from each other, has length n > 3 in the direction in parallel to the main axis (15), and is filled with insulation medium (20).
EFFECT: technical result consists in reliability improvement.
