Basic Line Connection Modules

Заказные данные
(7)

Basic Line Connection Modules are compact line infeeds for two-quadrant operation, i.e. no regenerative feedback. They are used when energy need not be fed back into the network.

Basic Line Connection Modules comprise a Line Connection Module and a liquid-cooled Basic Line Module.

As standard, the Basic Line Connection Module is positioned in the drive lineup so that the Motor Modules are arranged to the right. If Motor Modules are to be arranged to the left of the Basic Line Connection Module, option M88 (DC bus system for line-side Cabinet Modules) must be ordered.

Line Connection Modules contain the line-side infeed via main breaker with fuse switch disconnector or circuit breaker and establish the connection between the plant power system and the Basic Line Modules. It is equipped as standard with a radio interference suppression filter according to EN 61800‑3 Category C3.

Under full load, the DC link voltage is higher than the rms value of the rated line voltage by a factor of 1.32, and under partial load by a factor of 1.35.

If regenerative conditions occur in the drive line-up, a Motor Module can be used as braking chopper, which then converts excess energy to heat in a braking resistor.

Basic Line Connection Modules are suitable for connection to grounded TN/TT and non-grounded IT systems. The following voltages and power ratings are available:

Line voltage	Rated input current	Rated power
380 ... 480 V 3 AC	610 ... 1420 A	360 ... 830 kW
500 ... 690 V 3 AC	340 ... 1350 A	355 ... 1370 kW

For a Basic Line Connection Module a line reactor should be provided at the connection point depending on the line short-circuit power. This reactor is available as standard. However, it can be omitted if it is not required (option L22).
Further information can be found in the SINAMICS Low Voltage Engineering Manual.

Depending on the input current, the following versions are available:

≤ 800 A: Main circuit breaker with fuse switch disconnector
> 800 A: Circuit breaker, type 3WL, with option L25 as withdrawable circuit breaker

A fully controlled thyristor bridge is used to pre-charge the Basic Line Connection Module and the connected DC link. The thyristors normally operate with a trigger delay angle of 0°.

The power rating can be increased by connecting Basic Line Connection Modules in parallel. You must observe the following rules:

Up to four identical Active Line Connection Modules can be connected in parallel.
A common Control Unit is required whenever the modules are connected in parallel.
The parallel connection must be supplied from a common infeed point (i.e. the modules cannot be operated on different line supplies). For information on using line reactors, see section Basic Line Connection Modules → Overview.
A derating factor of 7.5% must be taken into consideration, regardless of the number of modules connected in parallel.
The main contactors or circuit breakers of the respective Line Connection Modules must close together and simultaneously. Monitoring is performed via the -X50 terminals of the respective Line Connection Module.
Option M88 must be ordered.

For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.
