Transformer for use in electric circuit for controlling lighting mechanism, has core circularly closed such that windings are arranged at distance from each other, where length of primary winding is smaller than that of secondary windings
摘要
<p>The transformer (1) has a primary winding (2) and two secondary windings (3) oppositely arranged on a transformer core (4). The transformer core is circularly closed such that the primary and secondary windings are arranged at distance from each other on the transformer core, where length (LP) of the primary winding is smaller than length (LS) of the secondary windings. The transformer core is in rectangular shape. The secondary windings exhibit a common connection (7).</p>
