A high quality standard is guaranteed by the use of high-quality materials and by the special competence of the employees. General This catalogue provides a general idea of Ruhstrat s standard programme for transformers with fixed transformation ratio, constructed as toroidal core or limb core transformers.

Applications deviating from the standard di are our strong point! Every product can be tailor-made according to your special application. Quality Control During its production di transformer has to undergo an intermediate test and after its production it has to undergo a thorough final electrical test; this is always done according to the respectively valid process instructions.

According to the quality standard DIN ISO the documentation of the measuring results is effected in appropriate test certificates. Low loss grain-oriented electrical steel is used as the core material. Depending on customer requirements and specifications the transformer dni can be produced using either copper or aluminum. Both wire and foil conductors can be wound depending on the current that is required. Insulation materials are chosen according to the required insulation coordination and the insulation class of the materials.

Power Power is calculated as 00532 product of secondary voltage [V] and secondary current [A], the result is [kva]. All power specifications refer to the collected power at the secondary side with: The limit values for short-time operation S2 arise from fig.

LOW VOLTAGE DRY-TYPE TRANSFORMERS ACCORDING TO DIN EN (VDE 0532/0570) TECHNICAL INFORMATION

It has to be ensured that there is a sufficient ventilation resp. With an ambient bde above 40 C the transformer must not be charged with the full rated current, due to the possible ambient temperature [ C] insulant class B 1,0 0,96 0,92 0,88 0,82 insulant class F 1,0 0,97 0,94 0,90 0,86 insulant class H 1,0 0,98 0,95 0,92 0,90 table 4.

With an altitude of installation of more vdd m above main sea level it is the same as with an excessive overtemperature: This is necessary, as the smaller atmospheric pressure leads to reduced cooling. Other deviating kinds of load and thyristor power controller operation of the transformers must be considered when they are constructed. Insulation For long life and high operation safety of a transformer it is very important that no part takes on an inadmissibly high temperature.

The insulation of the windings is most sensitive against warmth, as it can only bear a limited temperature with a normal duration of life. The insulation structure allows the use of transformers in dry rooms.

During its production the transformer has to undergo an impregnation with resin under vacuum and then it is dried in a furnace. Through this the transformers are protected against external influences. Admissible Winding Temperature The winding temperature may not exceed the limit temperature which depends on the insulant class. The limit temperature is the highest admissible permanent temperature of the winding at the hottest point.

The limit temperature emerges when adding the ambient temperature 40 Cthe admissible limit overtemperature and a safety addition. Taps on the primary side serve for don adaptation of the transformer to different mains voltage tolerances.

Transformers with Autowinding Autotransformers have a winding which consists of two parts. Both winding parts of the series winding and the parallel winding, are connected in series and are interspersed by the same magnetic flux.

The autotransformer has 00532 same mode of operation as the transformer with separate winding, which is also called transformer and also allows to step up and down voltages, but no physical separation.

In contrast to the complete transformer, there is only a part of the output power transferred from the input winding to the output winding with the autotransformer, by means of magnetic induction.

The transfer of the other part of the output power is effected by means of direct current conduction. Therefore, referring to the autotransformer one distinguishes between transitcircuit power and structural power.

The smaller the difference between input voltage and output voltage, the larger is the structural power. Degrees of Protection Depending on the site of installation and the intended purpose the parts of the transformer which are under voltage have to be protected against accidental touching and against penetration of water ved foreign bodies. For this reason, different kinds of protection are distinguished. The kinds of protection are indicated by a short sign which consists of two reference numbers for the degree of protection.

The first reference number gives an information about the protection degree against touching and penetration of foreign bodies. The second reference number marks the protection against the penetration of water. Vector Groups of Three-Phase Transformers The combination of the different connection systems for highvoltage winding and low-voltage winding is called vector group of the three-phase transformer. The vector group consists of at least one capital letter and one small letter as well as of a reference number.

If three-phase transformers have a neutral point star point which is lead outside, the vector group is completed by an N or n. The capital letter stands for the dkn winding, the small one for the output winding.

Depending on the connection of the consumer to the winding s beginning or end of the low-voltage side phase displacements from 0 resp. This phase displacement is stated by the reference numbers 0, 5, 6 and 11, whereas the phase displacement angle is the product of the reference number and the angle of Low loss and cold-rolled sheets for the electrical industry, with privileged magnetic direction, are used as core material.

The windings are made of insulated copper wire. With high rated currents streamlined copper wire and strip copper wire are used. The other insulations, materials are chosen according to the corresponding temperature stability class. As single-phase or three-phase construction, with separate winding or autowinding autotransformer. Advantages During the production process Ruhstrat Dry-Type transformers undergo a resin impregnation under vacuum with following furnace drying. This insulation makes a higher protection against external mechanical influences possible as well as a long service life and high operation safety of the transformers.

Winding If not indicated otherwise, Ruhstrat Dry-Type transformers are delivered with galvanically separated windings. In case of a construction with autowinding autotransformer the structural power is reduced. The autotransformer is mechanically smaller and therefore it can be produced at lower costs.

Degrees of Protection The following standard degrees of protection are possible: Further regulations, as for example certain marine classifications, can be considered upon request. Possibilities of application e. Voltages Ruhstrat Dry-Type transformers can be offered with voltages up to 10, V.
