Single-phase commutating reactors for DC operating mechanisms

Single-phase 4EM commutating reactors for converters are used in double-way circuits from converter assemblies as line reactors into the line-side infeed. They are connected such that alternating current flows through them.

It is their task to limit the line-side voltage dips during commutation of the converter. Also, by limiting the current rise rate di/dt the reactors limit the voltage rise rate du/dt at the thyristors used.

There are various series of reactors in the version Standard (Catalog LV 60):

• u_D ~ 2 % for following supply voltage:
  230 V AC
• u_D ~ 4 % for following supply voltage:230 
  V AC, 400 V

The figures are based on a frequency f = 50 Hz.

If these do not meet your requirements, versions in Standard modified or customized solutions are available. For more information contact "mdexx GmbH" in Bremen:

附件

Terminal covers for protection against inadvertent contact 
with exposed bar connections (DIN VDE 0106 Part 100/EN 50274)

The covers are suitable for all reactors and filters with 1-hole flat connectors. Assignment of the covers to the reactors and filters can take via the connection hole diameter.

If no other information is provided in the technical specifications, touch protection for the backs of hands against unintentional contact with live components can be created according to BGV A2 by using the covers.
