overview

with the sidrive i platform, you can conveniently accessall the relevant data from your drive systems anytime and anywhere.so, you can monitor and analyze the status and performance of yourdrive systems and derive possible optimization measures.

sidrive i and utilization are based on digitallyenhanced drive components. once your motors and converters are ableto report how they’re doing, our digital platform can use thesenotifications and data to provide you with a transparent overviewof the maintenance re of these drivecomponents.西门子中国一级代理商|变频器代理商

please note that in the first step, only the basic version of thesimotics sd next generation motor is e with simotics connect– a sensor box mounted on the motor. sensors measure importantoperating parameters such as mechanical condition, temperature andoperating condition, and forward these data via wlan to the digitalplatform sidrive iq for further analysis. these motors arei and you can benefit directly from the many advantages ofsidrive iq.

choose now if you would like to test the free version for 3 monthsor decide immediately for a contract period of 1 to 3 years.

sidac reactors西门子中国一级代理商|变频器代理商

it is well-known that faults in the supply network can be extremelyexpensive. against the background of the liberalization of theenergy market and the increasing number of non-linear consumers inthe network, supply problems have increased over the lastyears.
loads such as automation systems or data processing systems areextremely sensitive to radio interference voltages or deviation ofthe line voltage from a sine wave.

the availability of these plants is increased with reactors andfil­ters, which are adapted to the re of the in the plantoptimally. sidac reactors and filters are used throughout industryto reduce harmonics and increase the availability of plants anddevices.

application

single-phase commutating reactors for dc operating mechanisms

single-phase 4em commutating reactors for converters are used indouble-way circuits from converter assemblies as line reactors intothe line-side infeed. they are connected such that alternatingcurrent flows through them.

it is their task to limit the line-side voltage dips duringcommutation of the converter. also, by limiting the current riserate di/dt the reactors limit the voltage rise rate du/dt at thethyristors used.

there are various series of reactors in theversion standard(catalog lv 60):

u d ~ 2 %for following supply voltage:
230 v ac西门子中国一级代理商|变频器代理商

u d ~ 4% for following supply voltage:230 
v ac, 400 v

the figures are based on a frequency f = 50 hz.

if these do not meet your re, versions in standardmodified or customized solutions are available. for moreinformation contact "mdexx gmbh" in bremen:

accessories

terminal covers for protection against inadvertent contact
with exposed bar connections (din vde 0106 part100/en 50274)

the covers are suitable for all reactors and filters with 1-holeflat connectors. assignment of the covers to the reactors andfilters can take via the connection hole diameter.

if no other information is provided in the technicalspecifications, touch protection for the backs of hands againstunintentional contact with live components can be created accordingto bgv a2 by using the covers.
