Fault Tracing Thyristors

3ADW000488R0101 DCS880 Service manual e a

Thyristor test

Also the thyristor test provided by the firmware can be used:

−

Switch the drive to local mode (Drive composer entry/pro, control panel or local I/O).

−

Start the thyristor test by means of 95.24 Service mode = Thyristor test and set On and Run within 20 s.

−

During the thyristor test the main contactor will be closed and the thyristors are checked. The field current is

not released while the thyristor test is active and thus the motor should not turn.

−

When the thyristor test is finished check 05.22 Diagnostic for details.

−

For more information consult the

DCS880 Firmware Manual

Ripple monitor

The ripple monitor indicates that the ripple of the DC current is much higher than normal. In such a case, most

often one thyristor does not work. Its missing current contribution causes a deep dip in the direct current.

The structure of the current loop (current controller) will force the other thyristors to compensate the dip by a

certain overcurrent in order to keep the average current constant. Such a compensation results in a ripple

monitoring fault during motoring mode operation with alpha

≤

90°.

The reason for a current less thyristor may be:

−

A blown line fuse. This is possible only for converters with 20 ... 1000 A.

−

A fuse has disconnected one of the six thyristors. This is possible only for converters with 900 ... 5200 A (six

internal branch fuses).

−

A loose gate/cathode connector.

−

A thyristor does not get firing pulses or does not react to firing pulses.

−

The current controller may be totally mismatched to the DC load.

−

The AC mains network is causing that fault message. In this case, asymmetrical phase shift, uneven phase

voltage or critical designed power factor correction equipment or harmonic reduction equipment can be the

reason.

How to find a faulty thyristor

If a blown fuse is suspected, the problem is caused most often by a faulty thyristor. To make sure, that a

thyristor is the reason and needs to be exchanged fault tracing must be done in two different ways, depending

on the size of the converter.

In general, make sure, that all safety instructions, given within this manual or within the

Safety instructions

, related to the machine or the application itself, are obeyed.
