Abstract
A reclosing apparatus for the auxiliary systems of a plant, in particular a power station, has drive modules (81) for actuating electrical drives (23a, 23b, 33, 53a, 53b, 63, 73) of the auxiliary systems. Each drive module (81) of a reclosable drive (23a, 33, 53a, 63, 73) is assigned a reclosing module (82). When a voltage interruption occurs, the reclosing modules (82) switch the drives (23a, 33, 53a, 63, 73) by opening switches (22a, 32a, 52a, 62, 72). If the end of the voltage interruption is detected within a predetermined time, the reclosing modules (82) switch the drives (23a, 33, 53a, 63, 73) on again. Each busbar (2, 3, 5, 6, 7) which supplies a drive (23a, 33, 53a, 63, 73) provided with a reclosing module (82) is equipped with a microprocessor-controlled voltage monitoring device (21).
