发明名称 Electrical reactors.
摘要 <p>An electrical reactor has a core (11), for example composed of silicon steel plates, forming a closed magnetic circuit including a gap (14). A by-pass member (20) across the gap (14) forms a magnetic by-pass path around the gap (14). The by-pass member (14) may be a silicon steel plate with its plane parallel to the plane of the plates forming the core. A coil (15, 17, 18) is wound on the core (11). The inductance of the reactor depends upon magnetic saturation of the by-pass member (20). When current in the coil is small reactor inductance is large because the by-pass member (20) does not saturate, but when current in the coil is large the by-pass member (20) saturates and reactor inductance is reduced. The reactor can be employed for blocking leakage of noise generated at the time of commutation in a thyristor controlled converter.</p>
