AUTOMATIC MAINTENANCE OF THE VOLTAGE OF A DIRECT-CURRENT GENERATOR WITH THE AID OF A SATURATION CHOKE COIL

Abstract

An investigation was made of a saturation choke coil used to maintain a given voltage on a dc generator of type PN-75, which has a power output of 75 kw, a rotational velocity of 1500 rpm, a voltage of 440 v, and is driven by an asynchroous motor. The generator operated under unequal load conditions from 0 to 200 amp, i.e., brief current overloads of 40% occur. Such operating conditions caused sharp voltage oscillations and thus lead to a temporary disturbance of the technological process. Manual voltage control required great attention on the part of the maintenance personnel. The external characteristics with and without the saturation choke coil are presented. (Author)
