dv/dt filters plus VPL Siemens

Обзор

dv/dt filter plus VPL (Voltage Peak Limiter) limit the voltage rate-of-rise dv/dt to values < 500 V/μs and the typical voltage peaks to the following values according to the limit value curve to IEC/TS 60034‑17: 2006:

< 1000 V at U_line < 575 V

Standard motors with standard insulation and without insulated bearings can be used for inverter operation if a dv/dt filter plus VPL is used.

The dv/dt filter plus VPL are designed for the following maximum motor cable lengths:

• Shielded cables: 300 m (e.g. Protodur NYCWY)
• Unshielded cables: 450 m (e.g. Protodur NYY)

For shorter cable lengths (100 m shielded, 150 m unshielded) also refer to dv/dt filter compact plus VPL.

Note:

The maximum permissible cable length between the dv/dt filter and Power Module is 5 m.

Дизайн

The dv/dt filter plus VPL consists of two components, which are also separately supplied as mechanical units:

• dv/dt reactor
• Voltage limiting network, which cuts off the voltage peaks and feeds the energy back into the DC link.
