Introduction

This part of GB/T 22578 specifies the thermal evaluation method for electrical insulation systems (EIS) of electrical products containing liquid and solid components.

GB/T 22578.1 stipulates the general method of thermal evaluation test for liquid and solid components. GB/T 22578.2 specifies simplified test methods,

It can be used for the screening test before the GB/T 22578.1 test, and can also be used for quality control and evaluation when the secondary product is changed. GB/T 22578

The test methods specified in this part of the test are applicable to compressor electrical equipment, such as refrigerators, air conditioners and other products, and are suitable for evaluating motor-compression

The machine's electrical insulation material (EIM) and electrical insulation system (EIS). The test methods specified in this section are for evaluating the high temperature of refrigeration equipment

The ability to maintain equipment performance under high pressure conditions after immersion in refrigeration oil and refrigerant is very important.

This section and GB 4706.17 jointly apply to compressor products.

This section applies to the evaluation of EIM and EIS of hermetic motor-compressors used in refrigerators and air conditioners. Main test course

The sequence includes the evaluation of the durability of EIM and EIS in refrigerants and oils at high temperature and high pressure, and outlines how to evaluate the mechanical properties and heat resistance of EIM

The performance and chemical properties are evaluated, and these properties are closely related to keeping the equipment in good working condition.

This section specifies an autoclave test method. The autoclave should contain all the main EIM components, the component ratio and the actual electrical production

The product is the same.
