Unless the procedures of this part indicate otherwise, the principles

23、of IEC 60034-18-1 should be followed. IEC 60034-18-21 deals with the thermal evaluation and classification of insulation systems for wire-wound windings in respect of normal procedures as referred to in 5.3.2.1 of IEC 60034-18-1. This part of IEC 60034 is concerned with procedures of verification of

24、 the effects of changes in insulation systems for wire-wound windings covered by 5.3.2.2 of IEC 60034-18-1.

25、sulation component substitutions 1 Scope This part of IEC 60034 gives test procedures for the thermal evaluation and classification of changes and insulation component substitution in insulation systems used or proposed for use in a proven insulation system used in wire-wound windings. The test proc

26、edures are comparative in that the performance of a candidate system is compared to that of a reference system which has previously been proved by experience or has been evaluated by one of the procedures given in 60034-18-21 and to which the change or substitution is intended. 2 Normative reference

31、 an enamelled wire substrate 3 General guidelines 3.1 Category I insulation components 3.1.1 Phase insulation and ground insulation Insulation separating the windings from each other or from the magnetic core, for example slot liners, but not wedges, closures or top of slot packers all of which are

32、considered as category II components (see 3.2). Page5 EN600341822:2001 BSI 06-2001 3.1.2 Turn (conductor) insulation The resinous (enamel) coating or wrapped insulation, fibrous or film, on winding wire. 3.1.3 Impregnating varnishes These include both solvented and solventless varnishes. 3.1.4 Encap

33、sulant Moulded or cast insulation which completely encases the insulation system and which is the only barrier between the winding and the outer surface of the motor. 3.2 Category II insulation components Category II components include any constituent of an insulation system not covered by 3.1, as l

34、isted below. If the testing organization wants to consider some of these components as category I insulation components, it may do so. a) Series/parallel winding insulation as used on multi-voltage windings b) Insulation between auxiliary and main winding as used on single-phase motors. This is not

35、to be considered as phase insulation as described in 3.1.1. NOTE If winding insulation according to item a) or b) above is, in normal operation, stressed like phase insulation, then it must be tested as a category I component. c) Layer insulation: insulation which is interleaved between successive l

36、ayers of insulated wire in the same winding (same phase) d) Sleeving and tubing e) Slot wedges and closures NOTE If, in normal operation, the closure is stressed like the slot liner, then it must be tested as a category I component. f) Securement tapes and tie-cords g) Lead wire insulation 3.3 Defin

37、ition of generic identity Generic identity embraces both chemical and physical identity. Chemical composition shall be established from analytical data which should, for instance, be based on appropriate spectroscopic analysis (IR, etc.) complemented with thermogravimetric, DTA and atomic absorption

38、 analysis. Physical identity shall be established by mechanical and electrical tests appropriate to the component. DTA analysis can complement these tests. For several properties, like tan and modulus, dependence on temperature can complement both the chemical and physical picture. Where the insulat

39、ion component is made from more than one material, for example an adhesive bonded laminate, a mineral filled encapsulant, or a dual coat winding wire, generic identity shall be established with respect to each material of the component separately. In the case of a filled component, the relative amou

40、nts of filler and polymeric material shall be the same in both candidate and reference material. Page6 EN600341822:2001 BSI 06-2001 4 Documentation The following information shall be obtained for any proposed substitution material: a) detailed chemical analysis; b) supplier and reference; c) thickne

41、ss; d) thermal endurance, such as temperature index, and relevant standard or specification, for example: 1) IEC 60317 type for winding wire, 2) voltage rating, style or type for lead wire. The same information is also required for the reference system. 5 General substitution procedures The test pro

42、cedures to be followed for any particular substitution depend on the specific substitution involved. These are in clause 6. Any substitution to an insulation system shall be classified as a substitution procedure A, B, C or D. The action required in respect of validation for each procedure is listed

43、 below. NOTE Procedures A, B, and C are considered minimum requirements. At the discretion of the testing organisation procedure D may be used in place of procedures A, B or C. Procedure A If the data enables the investigator to establish the generic identity according to 3.3, documentation data as

44、described in clause 4 is sufficient to accept substitution without test. Procedure B Change requiring sealed tube test procedure (see clause 7). Procedure C Change requiring a single temperature ongoing programme using a procedure, for example motorette procedure, selected from IEC 60034-18-21. Proc

45、edure D Change requiring a full three-temperature test procedure as required by IEC 60034-18-21. Specific component substitutions are assigned to one of the above categories in clause 6. 6 Component substitution category 6.1 Category I component substitution 6.1.1 Phase insulation and ground insulat

46、ion 6.1.1.1 Generically identical, the same or increased thickness Procedure A applies. 6.1.1.2 Generically identical but thinner Procedure C applies. Page7 EN600341822:2001 BSI 06-2001 6.1.1.3 Generically different Procedure D applies. 6.1.2 Turn (conductor) insulation i.e. winding wire 6.1.2.1 Non

47、-bondable wire a) Where the insulation coating of the substitute material is generically identical with the original and where it conforms to the same IEC 60317 specification part or to one with a higher temperature class number, then; procedure A applies. b) For other substitutions; procedure D app

48、lies. 6.1.2.2 Bondable wire a) Where the insulation coating and bonding layer of the substitute material are identical with the original and where it conforms to the same IEC 60317 specification part or to one with a higher temperature class number, then; procedure A applies. b) Where the substitute

49、 bondable wire does not comply with item a); procedure D applies. 6.1.2.3 Aluminium instead of copper wire Thermal ageing test results on an insulation system containing copper winding wire are applicable to an otherwise identical system containing aluminium wire. Hence, substituting an aluminium wire for a copper wire with the same generic insulation coating having the same or higher temperature index number; procedure A applies.
