Brine spray testing apparatus of enameled wire stators

Abstract

The invention discloses a brine spray testing apparatus of enameled wire stators, which comprises a box body and a circulating pump (2). The box body is divided into an upper box body (6) and a lower box body (1). The upper box body (6) is internally provided with a rack (5) for placing a plurality of enameled wire stators (7). The wall of the box body is provided with a plurality of wiring holes (9) of the enameled wire (8). A sprayer is arranged at the top of the upper box body (6); the circulating pump (2) is mounted on the box body, and a water inlet of the circulating pump (2) is arranged in the lower box body (1) while a water outlet of the circulating pump (2) is communicated with the sprayer via a pipeline (3). The invention has the advantages of simple structure and better testing effect and can simulate real working environment of the enameled wire stators well and determine the testing time and the spraying amount of enhanced spraying according to requirements of service life of a motor.

Description

technical field [0001] The invention relates to a simulation test instrument for the insulation capacity of enameled wires in harsh working environments. Background technique [0002] In household appliances such as dishwashers, the working environment of the motor is very harsh, the environment is humid, the waterproof performance of the motor is required to be good, and the working life in the harsh working environment must reach a certain time. leakage current. In the inspection of the enameled wire manufacturing process, the salt water pinhole test is usually done to evaluate the insulation ability of the enameled wire, that is, the enameled wire is soaked in salt water to test whether there is leakage. The disadvantage of this test is that the test environment is very different from the real enameled wire stator, and it cannot simulate the real harsh working environment of the enameled wire, and cannot reflect whether the insulation capacity of the enameled wire has de...

AI Technical Summary

Problems solved by technology

The disadvantage of this test is that the test environment is very different from the real enameled wire stator, and it cannot simulate the real harsh working environment of the enameled wire, and cannot reflect whether the insulation capacity of the enameled wire has declined in the harsh working environment as the working time goes by.
