Abstract

The invention discloses an insulation test apparatus for enamelled wire stators. The insulation test apparatus includes a brine case, a test case, a fixed stand, enamelled wire stators, propellers, a linear slide rail unit, a spray head, and an atomizing nozzle. The test case is equipped with a through groove, wire passing holes and a water outlet, wherein the water outlet is communicated with the brine case. The fixed stand is arranged on the bottom transverse plane of the test case. The enamelled wire stators are arranged on the fixed stand. The propellers are arranged on the sidewall of the test case. The linear slide rail unit is arranged on the sidewall of the test case. The linear slide rail unit includes a slide rail fixed on the sidewall of the test case, and a slide block arranged on the slide rail in a sliding manner. The spray head is arranged on the slide block and communicated with the brine case. The atomizing nozzle is arranged on the top transverse plane of the test case and communicated with the brine case. Differences between a test environment and an actual working environment can be minimized, and thus the apparatus can better test changes of insulating properties of enamelled wires.

Description

Technical field: [0001] The invention relates to the technical field of enameled wires, in particular to an insulation testing device. Background technique: [0002] The enameled wire stator is widely used in various electrical appliances, and the working environment of some electrical appliances is very harsh, which requires the enameled wire stator to have a certain waterproof performance to ensure that it can achieve the expected service life in the harsh working environment; the wet working environment is harmful to the enameled wire The insulation requirements are very high, and there must be no leakage current. Therefore, the enameled wire stator needs to be tested and inspected before the product leaves the factory. In the performance test of the enameled wire, the salt water pinhole test is usually used to judge the insulation performance of the enameled wire. However, the existing insulation testing devices for enameled wire stators usually soak the enameled wires ...
