Embodiment Construction
[0017] figure 2 A test system according to the invention for a high-voltage technical instrument is shown, which in particular forms an inductance in its equivalent circuit diagram. The test system has an energy source 8 for power supply, wherein the energy source 8 can be formed, for example, by an existing power grid. Energy source 8 in figure 2 It is connected with the input end of the frequency converter 9, and the frequency converter can be constituted as a frequency converter circulating in the market. Alternatively, the test system according to the invention can also be operated with a motor-generator set 10 instead of an energy supply on the feeder side interacting with the frequency converter 9 . The motor-generator set 10 has the task of adapting and regulating the frequency and voltage of the test system within the test system. The motor-generator unit 10 thus constitutes the equivalent of the frequency converter 9 known to those skilled in the art. The output...

The present invention relates to a test system for high-voltage technology devices, in particular shunt reactors, as defined in the preamble of independent patent claim 1. The invention also relates to a method which can be carried out with this test system and is intended to test high-voltage technology devices according to coordinate patent claim 5. The general idea of the test system according to the invention is to provide a continuously adjustable inductance and a capacitance, which can be adjusted in discrete steps, on the secondary side of the test transformer in such a manner that said components form a series resonant circuit together with the test object in the form of an inductance. In the method which can be carried out with the test system according to the invention, a rough adjustment of the test system is carried out using the discretely adjustable capacitances of the capacitor bank by connecting individual capacitances of the capacitor bank via an iterative process if an undercapacitance is measured in the test system by means of a measuring device or by disconnecting individual capacitances if an overcapacitance is measured by means of the measuring device until a predefined threshold value of an overcapacitance prevails, with the result that fine tuning of the test system is then carried out by means of the continuously adjustable inductance in such a manner that said components form, together with the test object in the form of an inductance, a series resonant circuit which can be tuned to the point of resonance thereof.
Description
technical field [0001] The invention relates to a test system for high voltage technical instruments, in particular for shunt reactors, as defined in the preamble of independent claim 1 . The invention also relates to a method for testing a high-voltage technical device, which can be carried out with the test system according to the co-claimed claim 5 . Background technique [0002] Shunt reactors, which are also known as compensating choke coils, are sufficiently common in the prior art for those skilled in the art and the focus here is on their use in medium-voltage and high-voltage networks for improving the stability and stability of energy transmission systems. economy. The shunt reactor essentially has a coil comprising at least one winding and an iron core movable between the turns of the coil for controlling the inductance. These energy technology devices compensate the capacitive reactive power of transmission lines, in particular in lightly loaded or unloaded tra...
