16、CTROTECHNICAL COMMISSION _ ELECTRICAL INSULATION SYSTEMS (EIS) THERMAL EVALUATION OF COMBINED LIQUID AND SOLID COMPONENTS Part 3: Hermetic motor-compressors FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electro
17、technical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specificat
18、ions, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International
19、, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal dec
20、isions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for inte
21、rnational use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In o
22、rder to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be c
23、learly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certificatio
24、n bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, pr
25、operty damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited i
26、n this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying a
27、ny or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a Technical Specification when the required support cannot be obtained for the publication of an Internati
28、onal Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical Specifications are subject to review within three years of publication
29、 to decide whether they can be transformed into International Standards. IEC TS 62332-3, which is a Technical Specification, has been prepared by IEC technical committee 112: Evaluation and qualification of electrical insulating materials and systems.

This publicatio
31、n has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62332 series, published under the general title Electrical insulation systems (EIS) Thermal evaluation of combined liquid and solid components, can be found on the IEC website. The committee has deci
32、ded that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International Standard, reconfirmed, withdraw
33、n, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer.
34、PD IEC/TS 62332-3:2016 6 IEC TS 62332-3:2016 IEC 2016 INTRODUCTION This part of IEC 62332, which is a Technical Specification, describes a method for the thermal evaluation of electrical insulation systems (EIS) for electrotechnical products with combined liquid and solid components. IEC TS 62332-1
35、covers general test requirements. IEC TS 62332-2 covers a simplified test method which can be used as a screening test prior to conducting IEC TS 62332-1 testing or can be used as a quality control test to evaluate minor product changes. This part of IEC 62332 covers the evaluation and qualification
36、 of electrical insulation materials (EIM) and EIS which are applied to motor-compressors for the refrigerator or air conditioner. This document contains the evaluation items which are important to maintain the equipment performances in the refrigerator oil and refrigerant at high temperature and hig
37、h pressure. This document has been prepared in conjunction with IEC 60335-2-34. IEC TS 62332-3 is applicable to EIM and EIS evaluation for hermetic motor-compressors which are applied to the refrigerator and the air conditioner. The main procedures consist in the evaluation of EIM and EIS endurance
38、for refigerator and oil at high temperature and high pressure. It describes how to evaluate the mechanical, thermal and chemical degradation of the performances of EIM which have deep relation to keep the sound condition of the equipment. This simplified Technical Specification provides a test metho
39、d for sealed tube testing. The sealed tube should contain all the primary EIM elements in relative component ratios which compare with the actual electrotechnical device.
