Технические характеристики
The OCP (overcurrent protector unit) is an autonomous module of the SIMOVERT MASTERDRIVES series. It can also be easily retrofitted to already existing equipment that includes rectifier/regenerative units from the SIMOVERT MASTERDRIVES range.
It is connected as a supplementary device in the divided positive cable of the DC link between the rectifier/regenerative unit and the associated inverters.
The OCP is available as a chassis unit with 2 rated currents for DC links with the following supply voltages:
- 3-х фазная 380 V до 480 V AC + 10 % (DC link voltage 510 V DC to 650 V DC + 10 %
- 3-х фазная 660 V до 690V AC + 15 % (DC link voltage 675V DC to 930V DC + 15 %
OCPs for DC links with a supply voltage of 3-х фазное 500 V до 600 V AC + 10 % can be implemented with units for 3-х фазное 690 V AC. |
ОсобенностиUsing an OCP has the following benefits and advantages:
- Component and servicing costs are substantially reduced due to avoidance of fuse tripping and destruction of thyristors in the rectifier/regenerative unit.
- Availability is increased, minimizing expensive plant downtime and production stoppage times.
- The OCP can be bypassed in the event of a fault so that the rectifier/regenerative unit continues to be operational without the OCP.
Using an OCP is cost-effective and is therefore especially recommended for retrofitting in existing plant that uses SIMOVERT MASTERDRIVES. For new projects, the use of an AFE (fully pulsed with filter) may be more appropriate as this solution offers additional advantages and benefits.
An AFE
- prevents or eliminates inverter stalling (the OCP minimizes the negative effects of switch-off)
- produces considerably less network perturbations
- enables setting of the power factor up to the level of power factor compensation
- enables highly dynamic closed-loop control of the DC link voltage.
For the assignment of OCPs to rectifier/regenerative units, see “Selection and Ordering Data”. |
