Even in the field of technology, the 'straight path' is not necessarily the best solution. Careful planning, decades of experience in a wide range of applications and solid engineering work make REGATRON power supplies reliable, versatile and robust components, even for complex and unusual applications – made for the extraordinary!
Our customer is working on concepts for the transmission of high electrical energy and requires a high-performance DC source with more than 300 kW at voltages of up to 1000 V and currents of almost 4000 A for conceptional field tests. The main task is to supply large and highly inductive loads with optimum protection against the expected shock loads during various transient processes in the load circuit.
Various project areas were planned in advance in close co-operation with the customer's engineers:
The sophisticated transient protection concept particularly confronted the engineers with considerable problems, as reactive loads can cause extremely high voltage and current peaks for a short time, which far exceed the protective measures of a 'normal' DC module. The safe limiting of such transients requires corresponding design measures, such as those commonly used in power plants and high energy distribution systems.
The first picture shows the entire test setup just before delivery of the system. In the background there is the liquid-cooled DC source consisting of 12x TC.P TopCon power supply units, which can be switched quickly and safely from parallel to matrix operation by means of manual switch panels. This part of the system also includes the entire AC distribution including the main system switch, an emergency stop concept with 'Performance Level e' in accordance with the ISO 13849 standard as well as a remote operating unit and other communication interfaces. In the foreground is the customised protective circuit box for 4000 A, which is pre-tested in the factory with an appropriate load unit.
