ARTICLE ANNOTATION

quote
This article discusses the improvement of relay control units in the electrical centralization system based on modern and contactless elements. The electrical circuit of the improved unit has been created. The circuit consists of a gate consists of an isolated gate transistor (IGBT), a DC/DC converter, an optotransistor and other elements. In order to increase the reliability of the unit, 2 transistors were used on the current-carrying contacts of each circuit, which were connected to each other in series. Optotransistors were used for reliable control of transistors. The developed unit was installed and tested instead of blocks with a neutral small-sized plug (VI 1-400) on the executive unit P-62 and blocks I, VII, VIII of the electrical centralization system. The volt-ampere characteristics of the unit are obtained.
