Description

Technical Field

[0001] The present invention relates to the technical field of electrical performance testing, and particularly to an enameled wire insulation performance tester. Background Art

[0002] Enameled wire is a main variety of winding wire, which consists of a conductor and an insulating layer. After the bare wire is annealed and softened, it is coated with paint and baked multiple times; however, it is not easy to produce products that meet both the standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. Enameled wire is the main raw material for products such as motors, electrical appliances, and household appliances, and its insulation performance directly affects the operation safety and service life of the equipment. With the wide application of electrical equipment, as an important conductive material, the detection of the insulation performance of enameled wire is crucial. In enterprises that use enameled wire to manufacture motors, compressors, etc., a brine pinhole test is carried out after the enameled wire is wound into a coil to check whether the raw material enameled wire provided by the enameled wire manufacturer is qualified. Due to differences in the winding equipment process among different customers, for products made from the same enameled wire through different winding processes, the results obtained after the brine pinhole test vary greatly. Often, the enameled wire provided by the manufacturer meets all performance requirements when leaving the factory.

[0003] In the prior art, such as the "Enameled Wire Breakdown Voltage Testing Device" with the patent publication number: CN209784479U, it includes an insulating placement plate, a testing component, and a voltage tester. The testing component includes a plate-shaped conductive component, and a testing position is set on the plate-shaped conductive component for placing the enameled wire to be tested; the voltage output end of the voltage tester is connected to the plate-shaped conductive component, and the voltage input end of the voltage tester is used to connect the enameled wire. The enameled wire sample is placed on the plate-shaped conductive component, and the weakest insulating layer on the narrow side of the enameled wire sample is in contact with the plate-shaped conductive component, so that the voltage tester, the plate-shaped conductive component, and the enameled wire sample form a loop. The plate-shaped conductive component in this device can be in complete contact with the weakest insulating layer on the narrow side of the enameled wire, and can accurately test the breakdown resistance performance of the weakest insulating layer on the narrow side of the enameled wire, thereby obtaining the minimum breakdown resistance performance of the enameled wire sample and more accurately reflecting the performance of the enameled wire.
