SIMOREG DC MASTER 6RA70 converter

The SIMOREG is a line-commutated converter which requires the line voltage to commutate the current, it is not possible to maintain the current flow on failure of the line voltage (e.g. on a short interruption).

If regenerative feedback is used with four-quadrant devices, failure of the supply voltage orSIEMENS 6RA70 a line undervoltage can cause a fuse to trip (commutation failure). This is a physical effect of the converter circuit that cannot be prevented by closed-loop control. Single-phase alternating current is fed to the field circuit and three-phase current to the armature circuit. It is not possible to operate the power section from a DC system.

The SIMOREG 6RA70 can briefly be overloaded 1.8 fold if the device had previously been operated with a base-load current which is lower than the device rated current. If the device has been operated at rated current over a longer time it cannot be operated at overload. To avoid this, the thermal condition of the thyristors is calculated in the device to ensure the protection of the power semiconductors. Once the thermal limits are reached at overload, the current is automatically reduced to the rated current of the device or the device is switched off with an error message. The overload is configured using Catalog DA21 or the instruction manual.

The 6RA70 SIMOREG DC MASTER products will be totally discontinued effective October 1, 2020. From this time onwards, the product will no longer be produced, but spare parts will be available through October, 2022 (contingent upon component availability).

As an alternative, 6RA80 SINAMICS DC MASTER devices are available as compatible and innovative replacement products.

Devices with the following MLFBs are involved in this switchover:
