31、 ageing sub-cycle 15 4 blank Introduction IEC 34-18 comprises several sections. Section 1: General guidelines Section 21, 22, . .

32、. 29 will deal with test procedures for wire-wound windings. Section 31, 32, . . . 39 will deal with test procedures for form-wound windings. IEC 505 recognizes and defines all of the factors which might influence the time to end of life of electrical equipment insulation. Those factors of influen

33、ce causing ageing of the insulation are considered to be thermal, electrical, environmental (ambient), and mechanical. IEC 85 deals with thermal evaluation of insulating materials and insulation systems used in electrical equipment. In particular, the thermal classes of insulation systems used in

34、 rotating machines such as A, E, B, F and H, as well as the temperatures usually associated with these thermal classes, are established in IEC 85. In the past, materials for insulation systems were often selected solely on the basis of thermal endurance of individual materials. However, the second

35、edition of IEC 85 recognizes that such selection may be used only for screening materials prior to further functional evaluation of a new insulation system which is not service-proven. This evaluation is linked with earlier service experience through the use of a service-proven refererence insula

36、tion system as the basis for comparative evaluation. Service experience is the preferred basis for assessing the thermal endurance of an insulation system. IEC 611 describes the methodology based on the linear Arrhenius relationship (log life versus reciprocal absolute temperature), to be used as a

37、 guide in the preparation of test procedures for specific types of electromechanical products where the thermal ageing factor is considered to be dominant. IEC 727 deals with evaluation of electrical endurance of insulation systems. IEC 791 gives instructions for evaluation of data from service

38、experience and from functional tests. IEC 792 describes general principles for multi-factor functional testing of insulation systems. In the winding of an electrical machine, different factors of influence can be dominant in different parts (e.g. turn insulation and end winding insulation). The

39、refore, different criteria may be used to assess those parts of the insulation. It can also be appropriate to apply different procedures of functional evaluation to these parts. The large differences found in the rotating electrical machine windings, in terms of size, voltage and operating condit

40、ions, necessitate the use of different procedures of functional evaluation to evaluate various types of windings. These procedures can also be of different complexity, the simplest being based on a single ageing mechanism (e.g. thermal or electrical). In the present state of the art, only thermal

41、 and electrical endurance testing procedures can be specified in some detail. Principles of mechanical, environmental and multifactor functional testing are briefly described to provide a basis for provisions to be developed later where appropriate. 1 Scope This part of IEC 34-18 describes pro

42、cedures for functional evaluation of electrical insulation systems used or proposed to be used in rotating electrical machines within the scope of IEC 34-1, and the classification of those insulation systems. This part (Part 1) provides general guidelines for such procedures and classification pri

43、nciples, whereas the subsequent parts give detailed procedures for the various types of windings. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IEC 34-18. At the time of publication, the editions in
