Variable-frequency series resonance test device

Abstract

The invention relates to the technical field of series resonance test devices, in particular to a variable-frequency series resonance test device, which comprises a variable-frequency series resonance tester, an assembling groove is formed in the bottom surface of the variable-frequency series resonance tester, and an assembling frame is inserted into the assembling groove; the limiting bottom column is arranged on the top face of the bottom plate of the assembling frame, the top of the limiting bottom column is sleeved with a sleeve, and a pressing plate is arranged at the top end of the sleeve; the edge groove is formed in the surface of the variable-frequency series resonance tester, a braking insertion plate is inserted into the bottom surface of the edge groove, the bottom end of the braking insertion plate is inserted into a limiting insertion groove, and the limiting insertion groove is formed in a bottom plate of the assembling frame; the frequency conversion type series resonance test device has the beneficial effects that the wire body is wound on the sleeve, the pressing plate is lifted along with the increase of the winding height of the wire body, namely, the first spring is tensioned, and in the wire body winding process, the wire body penetrates through the wire penetrating frame to be cleaned by the two sets of cleaning brush plates, so that particulate matter is prevented from crushing a wire body protection layer when the wire body is wound.

Description

technical field [0001] The invention relates to the technical field of series resonance test devices, in particular to a frequency conversion type series resonance test device. Background technique [0002] The frequency conversion series resonance test is different from general-purpose test instruments. The biggest feature is that the same set of equipment can be used for AC withstand voltage tests of different electrical equipment such as cross-linked cables, transformers, GIS, motors and generators, etc., except for this selection catalog In addition to giving a series of typical and commonly used models for users to choose, it is usually necessary to design a configuration scheme according to the user's test product range and test requirements to meet the test requirements of different regions, different users, and different test products. [0003] In the prior art, the frequency conversion series resonance tester needs to be used with a large number of wires. The used w...
