Трансформаторы для согласования с сетью для SIMODRIVE 611 приводов - Трехфазные трансформаторы

The SIMODRIVE 611 converter system has been designed for direct connection to TN networks with rated voltages 3 AC 400 V, 3 AC 415 V, and 3 AC 480 V. Specially designed matching transformers are available so that the system can be used with other network configurations such as IT or TT networks. This broad range of transformers covers most mains voltages used in industrial regions worldwide.

TN networks have a low-impedance electrical connection between the reference ground potentials of the current source and the protective conductor of the electronic equipment. If this is not the case, these connections must be implemented with the help of a separate-winding transformer whose secondary neutral point is grounded with a protective conductor potential connected to the protective conductor of the converter.

In this way, the voltage stress for the isolating distance between the power circuits (mains potential) and the open and closed-loop control circuits (protective conductor) within the clocked PMW is fulfilled to DIN EN 50178 for the rated voltage of 300 V.

Series-connected protective devices against shock currents or for fire protection (e.g. residual-current-operated protective devices) must be AC/DC sensitive in accordance with the requirements of DIN EN 50178. For other residual-current-operated protective devices a separate-winding transformer must be connected to the incoming circuit of the converter for decoupling.

If only a voltage level regulation for TN networks is required, one of the aforementioned transformers can be used as an autotransformer.
