ARRANGEMENT AND METHOD FOR REDUCING CAPACITIVE CURRENT |
摘要 |
An arrangement for reducing capacitive coupling com- prises auxiliary windings (112, 113, 114) in a space be- tween a winding (110) and another part (111) of an electrical device. The winding and the other part can be, for example, primary and secondary windings of a transformer. A first end of each auxiliary winding is coupled to a fixed electrical potential via an electrical element. In a direction (126) of a magnetic axis of the winding, at least one of the auxiliary windings is shorter than a length of an auxiliary winding system consisting of the auxiliary windings. The shorter auxiliary winding constitutes a capacitive shield that reduces the capacitive coupling between the winding and the other part without having a high induced voltage that would in turn couple in a capacitive manner. |
