© Siemens AG 2008 When reliability counts: Reactors and filters for all industries and applications SIDAC Answers for industry. WS_SIDAC_engl.indd 1 07.11.2008 11:47:40 Uhr © Siemens AG 2008 When everything must run smoothly and safely: SIDAC reactors and filters There is a large variety of electrical drive engineering that exists in every industry and manufacturing sector. Due to the complexity and level of automation, many modern electronic systems are extremely susceptible to interference, such as radio interference voltages or line voltage deviations from sine-wave shape. This may cause reduced system availability, but it doesn‘t have to. Whenever reliable components, like our SIDAC reactors and filters, are used with optimal equipment design and rating, nothing will prevent a smooth operation. Global reliability Whether current smoothing or the suppression of interference signals is required, SIDAC reactors and filters can be used in almost every industry around the world. With a robust and innovative design, SIDAC meets virtually every international standard. Using SIDAC components, AC and DC drives can be equipped with the appropriate system components that match all rating classes and every industrial application industry. In addition, we offer filter reactors for choking reactive-power compensation systems. Our wide range of equipment is not restricted to standard applications but can be customized as necessary. Type-tested safety for all applications As rough as the industrial environment can be – SIDAC reactors and filters always work with a high degree of reliability. This is because all our product components have been tested under the most critical conditions – that exceed the test requirements of IEC 61558-2-20: Climatic tests IEC 60721-3-1/2/3 according to class: 3K3/1K4/2K3/3C3/1C2/2C2/3S2/1S2/2S2 Vibration and impact tests IEC 60721-3-1/2/3 according to class: 1M2/2M2/3M4/1M2/2M2 Whether used for system or assembly components – SIDAC reactors and filters provide the most economical individual solutions. 2 WS_SIDAC_engl.indd 2 07.11.2008 11:47:59 Uhr © Siemens AG 2008 Advantages at a glance Wide power range Reactor power: 0.1–2,000 kVA, currents: max. 1,640 A, filter power: for drives with a power output of max. 900 kW Voltage ranges 1 x 200...400 V AC, 3 x 380...750 V AC, customer-specific up to max. 3.6 kV Operating safety Rated voltage higher than operating/supply voltage Models and sizes Comprehensive supply range matching standard applications Device allocation Components can be easily integrated into systems Service Short delivery times for equipment and spare parts thanks to worldwide logistic network Approvals Worldwide use of components possible due to UL approval Maintenance Very long service life at minimum maintenance expense Installation Fast commissioning, short set-up times, easy installation Mounting Simple screw fastenings Connections Screw or plug-on screw terminals, flat-type terminals Operating safety Long-term, worldwide availability of spare parts Environment Environmentally compatible manufacture and materials, low power losses Product overview SIDAC reactors SIDAC filters • Commutation reactors for power converters • Radio interference (RFI) suppression filters • Line reactors for frequency converters • Dv/dt filters for frequency converters • Output reactors for frequency converters • Sine-wave filters for frequency converters • Smoothing reactors for DC drives • Filter reactors for reactive-power compensation systems 4EM 1 AC commutation reactor 4EP/4EU 3 AC line reactor 4EF151 3 AC RFI suppression filter 4EF11 3 AC sine-wave filter 3 WS_SIDAC_engl.indd 3 07.11.2008 11:48:24 Uhr © Siemens AG 2008 Smooth operation from network to motor: SIDAC reactors and filters for AC drives In every industry or application where frequency converters are used, such as: electrical and mechanical engineering, process industry fans, conveyor belts or hoisting gear, SIDAC reactors and filters are essential components. They reduce line harmonics as well as the effects of the converter supply to the motor. They protect and take care of the converter, thus ensuring the trouble-free operation of your machinery and systems.

For all standard applications, we offer reactors with a uk 2%-related voltage drop. For networks with very low line impedances, we can provide reactors featuring uk 4%. The inductance of SIDAC line reactors is characterized by a high linearity, which prevents troublesome DC link fluctuations as a result of load changes. Rated voltages of the line reactors are at least 40% higher than the operating voltage. 3 Masters in minimizing charging current peaks: SIDAC output reactors SIDAC output reactors reduce the charging current peaks generated by a clock signal and the line capacitance. With unshielded lines, motor cable lengths are up to 300 m and with shielded lines, the max. cable length is 200 m. Owing to a rated voltage of 500 V + 5%, SIDAC output reactors can be used with almost any common power network in Europe and North America. 4 Safe motor protection: SIDAC dv/dt filters SIDAC dv/dt filters are often used with frequency converters in the chemical industry. They maintain voltage rise ratios of < 500 V/µs and provide reliable motor protection by cutting voltage peaks to a defined value. Their rated voltage of 500 V + 10% and permissible clock frequency of 4 kHz make them suitable for the greatest variety of applications. With unshielded lines, the max. permissible motor cable length is 300 m, with shielded lines, it is 200 m. 5 Shaping voltages in sine waves: SIDAC sine-wave filters If a motor is to be supplied with an almost sinusoidal-like voltage, as is typical for the chemical industry or some household applications, SIDAC sine-wave filters should be used. They maintain voltage rise ratios of < 500 V/µs. They are excellent in noise-sensitive areas of application, since they reduce magnetic motor noise. With a rated voltage of 500 V + 10% and a permissible clock frequency of 8 kHz, they are suitable for many applications. Long motor cables can, of course, be used here, too: the maximum lengths are 300 m for unshielded cables and 200 m for shielded cables. Current Line reactor uk 4% Line reactor uk 2% No line reactor Motor 2 Frequency converter screening: SIDAC RFI suppression filters When interference from individual frequency converters needs to be reduced, SIDAC RFI suppression filters are indispensable. They can be easily assigned to frequency converter classes. They reduce radio interference voltages to the required values, thus ensuring that equipment in the vicinity is not affected by radio waves. In conjunction with SIDAC line reactors, they provide an optimum screening of frequency converters. Typical interference spectrum without RFI suppression filter Lower interference spectrum with RFI suppression filter . 5 WS_SIDAC_engl.indd 5 07.11.2008 11:49:06 Uhr © Siemens AG 2008 Proven technology for an increased availability: SIDAC reactors and filters for DC drives Depending on the field of application, DC drives can provide a cost-effective alternative to AC drives using frequency converters. In these cases, SIDAC reactors and filters make a remarkable contribution by significantly increasing the operating safety and availability of power converter systems. Reliable reduction of current ripples: SIDAC smoothing reactors DC drives are typically used as main drives for printing machines, rolling mill or coiling drives as well as traction and hoisting gear drives in the crane and elevator industry. SIDAC smoothing reactors reliably reduce current ripples in the motor circuit. Reactor models are available from the kW to the MW range. Upon request, we will rate and determine the required component parameters for you. You would certainly benefit from our long-term experience about sizing and rating drive components. Smoothing reactors for decoupling on a printing machine: SIDAC in use In the application example on the left, a 12-pulse DC main drive of a printing machine, smoothing reactors are used as decoupling reactors. The reactors reduce the current ripples of the converter units and thus the harmonic stress of the DC motor. This is a clear advantage in terms of motor service life. Using reactors for decoupling the two power converters enables two 6-pulse rectifier sets to be operated in parallel, creating a 12-pulse phase effect at the primary side of the system transformer. In short: SIDAC reactors make a remarkable contribution to reducing system harmonics and improving system conditions. Line/ commutation reactor RFI suppression filter Power system Power converter Smoothing reactor Motor Total current of DC motor (Id = 620 A) DC current System perturbations under control: SIDAC line/commutating reactors and SIDAC RFI suppression filters Whether frequency converters or DC converter drives are used, their system perturbations are similar. This is why the same components are used at the line side as for AC drives: line and commutating reactors as well as RFI suppression filters. With large DC drives in particular, a sufficiently high inductance will be ensured – a requirement that is easily met by SIDAC reactors and filters with top-standard criteria such as robust design and high availability.

As a result, the harmonic load and THD-V (Total Harmonic Distortion – Voltage) of the network are rising. This increases the cost of electricity, maximizes transmission losses and adds to the stress of transmission and distribution systems. But there is a solution. The use of filter reactors prevents capacitors connected in the network from resonating with the network inductances at an undefined level. The filter reactors are tuned to a defined series resonant frequency with the capacitors, in consideration of an applied ripple control system. High safety in extreme applications Filter reactors in reactive-power compensation systems are connected to the network in combination with capacitors. Depending on the level of choking, capacitors and filters form a series resonant circuit with a defined resonant frequency: p = 5,67 % with fres = 210 Hz/p = 7 % with fres = 189 Hz/p = 14 % with fres = 134 Hz A high harmonic load has already been taken into account for the rated current. In addition, SIDAC filter reactors permit continuous overloading, which may be 5% above the harmonic level. This ensures the safety for extreme applications. An integrated temperature monitoring system reliably signals any overload. In addition, the high linearity of the inductance provides precise tuning of the filter circuit even when short-time surge loads are applied, during start-up. Constant inductance under any condition Filter reactors are interconnected with capacitors to form filter banks with a defined reactive power in kvar. SIDAC filter reactors are available in the customary sizes of 5 to100 kvar. They are characterized by a high degree of overloading capability, which increases the operational safety of the network in conditions of varying harmonic contents. Depending on the level of choking, the linearity of the inductance remains constant up to 1.8 times the nominal current. This ensures that the filter circuit remains tuned to the resonant frequency even when excessive currents are applied. Not even high inrush currents can saturate SIDAC filter reactors. The inductance remains constant and undefined detuning of the filter circuit is prevented.

Practice has shown that it is often the small modifications that turn a standard product into a customized solution. Often special cases are designed for a reactor and the connection technique must be adapted so that no interference radiation is emitted to the surroundings. More expenditures are required when solutions must be developed for large reactors with special applications. In shipbuilding, for example, construction and design must comply with international marine classifications. Limited space and high temperatures require solutions with forced cooling. Inductances with tappings and specified connection techniques may be necessary. Railway engineering and its special ambient conditions also require individual solutions, such as, vibration strength.

This filter can either be combined with an output reactor or a line reactor – both installed in one metallic case. This is designed as a complete base, so that the frequency converter can be mounted on the filter, saving space. If no input or output reactor is required, the RFI suppression filter can also be placed in the case on its own. Depending on the requirement, the filter connection cables are shielded or unshielded and, from the point of view of EMC, positioned in such a way that interference emitted to the surroundings is avoided as much as possible. The advantage of this design concept is that the system is very flexible – and can therefore be tailored to individual customer needs. Depending on the application, solutions with different technical features can be put into practice with optimal results. Combination filter, line reactor incl.
