Fields of application
|
|
|
Isolating transformer conform to IEC/EN 61558-2-4 for general purpose, e.g. as safe isolation for devices according to the requirements of VDE 0700 / EN 60335, or as net distribution transformer for TN-net systems. Suitable for potential free nets, test systems and as power-ratio transformer.

Description
|
|
|
Three-phase transformer, built as an isolation transformer conform to EN 61558-2-4. Basically this type size can be built in any vector group. If there is no vector group given, we use Dyn5 as default (star point can have full load from the outside conductor).
Please consider the difference between outside conductor voltage and phase voltage to star point at the different vector groups.
For a safe and easy transport, the transformers have crane hooks at the upper side. The used block terminals are shock proof conform to VBG4. A vacuum varnishing makes a low hum-noise possible.

Advantages of energie-efficient transformers
|
|
|
High efficiency. Energy-efficient due to low no load - partial load losses (in partial load or no load operation you find only iron losses and no resp. very low copper losses). Low heating (housings with IP 54 are possible). High economic efficiency (reduced losses save energy costs). Environmental-friendly (reduced losses -> less energy costs -> less Co2 emission). Low hum noise. Customer specified construction is possible. Amortisation of the extra costs is possible within a few years due to the energy savings. The energy savings can be a multiple of the purchase prize during the whole lifetim of the device. All norms are redeemed.

Customer specified solution - Customer’s demand
|
|
|
Our customer builds test and simulation systems for photovoltaic systems. Photovoltaic cells react different during possible weather conditions. The characteristics and the behaviour of various solar cells should be set and programmed freely. The transformer has to generate and supply the needed power in many various steps.
|
|
|
Solution
|
|
|
We construct a 300 kW three-phase transformer for twelve pulse rectification with the vector group Dddyy. Like this the rectified voltage is low on ripples and stable. The powersteps can be reached by several primary steps.
