General
•
Thyristor modules TSM series may only be used for the purpose they have been designed for.
•
Thyristor modules TSM series may only be used in combination with appropriate pre-switched grid
separator device.
•
Thyristor modules have to be projected in such a way that in case of any failure no uncontrolled
high current and voltages may occur.
•
The devices in operation have to be protected against moisture and dust, sufficient cooling has to
be assured.
Attention
Due to the switching principle of the thyristor module the power capacitors are permanently loaded to
the peak value of the grid voltage (DC voltage) even when switched off. Therefore the following rules
have to be obeyed in any case:
•
For standard PFC-systems (without reactors) power capacitors of 440 V nominal voltage have to
be used; for detuned systems PFC capacitors of 525 V nominal voltage have to be used.
•
Due to the high voltage (2 × peak value of nominal voltage) that occurs, the discharge resistors of
the power capacitors have to be replaced by special types.
•
In dynamic systems with TSM modules no fast discharge reactors may be used (reactor = DC-
wise short circuit).
•
For standard PFC-systems 2 current limiting reactors are mandatory per thyristor module.
•
Thyristor modules in general have to be protected by superfast electronic fuses. Principles for
dimensioning have to be considered. Fuses in the system have to be marked.
•
Due to the special switching, the PFC capacitors are fully loaded even when the particular step
has been switched off. Protection against contact has to be guaranteed. Warning signals in the
systems are required.
•
Even in switched off state no electrical isolation is achieved for electronic switches. Therefore
parts of the systems may not be touched after switching off the complete system before the
capacitors have been completely discharged.
FAILURE TO FOLLOW CAUTIONS MAY RESULT, WORST CASE, IN PREMATURE FAILURES OR
PHYSICAL INJURY.
