The invention relates to the field of electromagnetic appliance design technique, especially an electromagnetic appliance test system, which artificially combines a main circuit test, an electromagnetic mechanism test and an electromagnetic mechanism dynamic characteristic. The voltage transformer system L, M, N and the voltage signal conditioning module J collect and process main circuit line voltage signal, fracture voltage signal, and voltage signal of electromagnetic appliance electromagnetic mechanism coil. The current mutual inductor system X, Y and the current signal conditioning moduleK collect and process main circuit current signal and current signal of electromagnetic mechanism. Collected electric voltage, current signals are putted into the comprehensive analysis module D by the high speed signal collection card A and the test program module C for measuring and switching actual measurement parameter. The artificial parameter inputted from the test parameter and the simulation software data-base E are comprehensively analyzed by the comprehensive analysis module D. The analysis result is inputted into the service life estimation module S and the wave shape display module G, for service life estimation of model machine as well as waveform display test and related image processing.
Description
Electromagnetic Electrical Test System technical field The invention relates to the technical field of electromagnetic appliance design, in particular to an electromagnetic appliance testing system. Background technique In the prior art, the theoretical analysis, product design, and performance inspection of low-voltage electrical appliances are extremely complicated. When analyzing and designing low-voltage electrical products, in addition to using the traditional theories of low-voltage electrical appliances: electric contact theory, arc theory, heating and electrodynamic theory, electromagnetic mechanism theory, etc. to conduct necessary theoretical derivation, analysis and calculation, a lot of experience is also used data. Even so, sometimes there is still a large difference between the design calculation data and the actual performance of the product, requiring repeated revisions and tests, resulting in a long development cycle and large capital investment. It is ve...
