FIELD: electricity. ^ SUBSTANCE: device for automatic control of a reactive power compensation comprises a chain of serially connected capacitor battery and inductance coil, at the same time the capacitor battery and the inductance coil are separated with a set separation ratio into two parts representing the main (L1, C1) and operational (L2, C2) chains connected to each other serially and connected to a contact wire via a high-voltage breaker, and in parallel to the operational chain (L2, C2) a bipolar commutator is connected, an input of a control unit of which is connected to an output of a contact network voltage sensor. ^ EFFECT: improving device reliability and its simplification. ^ 2 cl, 1 dwg |
