Embodiment Construction

[0029] Such as figure 1 As shown, a kind of dielectric strength testing device of insulating material of the present invention is made of following several parts:

[0030] 1—electrode system 2—fixed end 3—moving electrode 4—fixed plate 5—moving plate 6—bracket 7—tensile member 8—test sample 9—ring limiter 10—insulating sleeve 11—nut

[0031] Among them, 3-5 fixed electrodes are embedded in the fixed plate 4 at equal intervals, and the corresponding 3-5 moving electrodes 3 are embedded in the moving plate 5 at equal intervals.

[0032] The test sample is sandwiched between the fixed plate 4 and the movable plate 5, wherein an annular stopper 9 is installed on the upper end of the test sample to prevent the test sample from falling off during the experiment. According to the thickness of the film sample, the movable electrode 3 can be adjusted to change the electrode spacing, and the fixed plate 4 and the movable plate 5 support the film sample so that the sample is just stuck ...

Abstract

The invention discloses a detecting device which comprises an electric appliance assembly and a detecting assembly. The detecting device is characterized in that the detecting assembly comprises a fixed plate 4 and a moving plate 5 which are vertically arranged on a support 6 and transversely placed side by side, holes are formed in the fixed plate 4 and the moving plate 5 in the same horizontal direction respectively and used for placing an electrode system 1, annular limit parts 9 are arranged on the upper ends of the adjacent ends of the fixed plate 4 and the moving plate 5, a stretching part 7 is arranged between an upper transverse plate and a lower transverse plate, in the horizontal direction, of the support 6, and a fixed electrode 2 and a moving electrode 3 of the electrode system 1 are connected to the electric appliance assembly and the ground respectively. The detecting device is simple in structure, convenient to install, low in manufacturing cost and capable of being widely used in academic institutions and industrial inspection departments.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for testing the dielectric strength of a film-type insulating material in a stretched state in a low-temperature environment. Background technique [0002] With the development of superconducting materials and superconducting technology, the application of superconductors in electric power continues to expand, and the development and production of superconducting electrical equipment are increasingly industrialized. The testing of the insulation performance of insulating materials is not only the need of the electrical manufacturing department and the power operation department, but also the needs of scientific research institutes and colleges and universities related to it. For electrical equipment with a large capacity, two insulation indicators, the absorption ratio and the polarization index, should be tested. For the insulation materials produced in the laboratory or...
