附件西门子一级代理商|PLC中国代理商

Terminal covers for protection against inadvertent contact
with exposed bar connections (DIN VDE 0106 Part 100/EN 50274)

The covers are suitable for all reactors and filters with 1-hole flat connectors. Assignment of the covers to the reactors and filters can take via the connection hole diameter.

If no other information is provided in the technical specifications, touch protection for the backs of hands against unintentional contact with live components can be created according to BGV A2 by using the covers.

Reactors for AC operating mechanisms

Three-phase mains reactors for frequency converters are used in line-side infeeds. They are connected such that alternating currents with line frequency as the fundamental wave frequency flow through them.

The reactors limit the circuit feedback which can arise in the form of harmonics. In addition they reduce the alternating currents, with frequencies caused by switching of the input rectifier, in the DC link capacitors.

Two reactor series are available in the version Standard (Catalog LV 60):西门子一级代理商|PLC中国代理商

• Reactors with a related voltage drop uD of ~ 2 % for operation with converters without power recovery.

• Reactors with a related voltage drop uD of ~ 4 % for operation with converters together with autotransformers with power recovery and for use in networks which have a uk network of < 1 %.

If these do not meet your requirements, versions in Standard modified or customized solutions are available. For more information contact "mdexx GmbH" in Bremen:

Iron output reactors for AC operating mechanisms

Output reactors are used on the load side of frequency converters and motor currents flow through them.

Output reactors compensate capacitive charge-reversal currents with long cables and, in the case of long motor cables, limit the dv/dt at the motor terminals. This enables the use of longer motor supply cables:

• 200 m shielded motor cable

• 300 m unshielded motor cable

Use of iron-core output reactors:西门子一级代理商|PLC中国代理商

• Operating mechanisms with standard and trans-standard asynchronous motors and a rated motor frequency (field weakening frequency) of up to 87 Hz and a maximum frequency of 200 Hz.

• Operating mechanisms with reluctance or permanently excited synchronous motors with a maximum frequency of 120 Hz.西门子一级代理商|PLC中国代理商

Note on the versions Standard (Catalog LV 60):

The following generic parameters apply, which must not be exceeded:

• Maximum motor cable length 200 m, shielded cable

• Maximum motor cable length 300 m, unshielded cable

• Maximum motor cable cross-sections for performance class:

• up to 2.2 kW/1.5 mm²

• > 2.2 kW ≤ 7.5 kW/2.5 mm²

• > 7.5 kW ≤ 11 kW/4 mm²

• > 11 kW ≤ 22 kW/10 mm²

• > 22 kW ≤ 30 kW/16 mm²

• > 30 kW ≤ 37 kW/25 mm²

• > 37 kW ≤ 50 kW/35 mm²

• > 50 kW ≤ 75 kW/70 mm²

• Maximum clock frequency 8 kHz

• Maximum motor frequency of output reactor 200 Hz

• Maximum motor frequency of sinewave filter 100 Hz

• UN 3 AC 500 V ±5 %.西门子一级代理商|PLC中国代理商
