Abstract

The invention relates to a switch assembly (1) comprising a switch (17) and a servo drive system. The servo drive system has a driveshaft (17), a motor (12) for driving the driveshaft (16), a power section (11) for supplying energy to the motor (12), a control unit (10), and a feedback system (4). The feedback system (4) is designed to determine at least two values for the absolute position of the driveshaft (16) and generate a feedback signal on the basis of the at least two values. The control unit (10) is designed as a programmable safety controller and is designed to actuate the power section (11) on the basis of at least one target value. On the basis of the feedback signal, the control unit (10) is designed to influence the operation of the motor (12), identify the presence of at least one safety-relevant event, and transmit at least one control signal to the power section (11) in the case of the safety-relevant event. The power section (11) is designed to initiate or carry out at least one safety measure on the basis of the control signal.

Description

technical field [0001] The invention relates to a switching device, in particular a tap changer device, having a switch, in particular an on-load tap changer, and a servo drive system for the switch, in particular an on-load tap changer. Background technique [0002] In a substation there are a large number of switches for different tasks and with different requirements. In order to actuate the corresponding switches, these have to be actuated by the drive system. These switches are in particular on-load tap-changers, load diverter switches, selectors, double diverters, reversers, preselectors, power switches, load switches or disconnectors. [0003] On-load tap-changers are thus used, for example, for switching without interruption between different winding taps of electrical operating components, such as power transformers or adjustable choke coils. Thus, for example, the transmission ratio of the transformer or the inductance of the choke can be changed. A double commu...
