Unless the procedures of this part indicate ot
23、herwise, the principles of IEC 60034-18-1 should be followed. IEC 60034-1 8-21 deals with the thermal evaluation and classification of insulation systems forwire-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 proce
24、dures of verification of the effects of changes in insulation systems for wire-wound windings covered by 5.3.2.2 of IEC 60034-18-1.

25、s - Classification of changes and insulation 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 i
26、n wire-wound windings. The test procedures 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 substitutio
27、n is intended. 2 Normative references O The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 60034.

32、closures or top of slot packers all of which are considered as category II components (see 3.2). O BSI 06-2001 Page 6 EN 60034-18-22:2001 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 includ
33、e both solvented and solventless varnishes. 3.1.4 Encapsulant 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 const
34、ituent of an insulation system not covered by 3.1, as listed 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 ma
35、in winding as used on single-phase motors. This is not to be considered as phase insulation as described in 3.1 .I. 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 insulati
36、on: insulation which is interleaved between successive layers 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) Secureme
37、nt tapes and tie-cords g) Lead wire insulation 3.3 Definition 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.) comple
38、mented with thermogravimetric, DTA and atomic absorption 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 6 and modulus, dependence on temperature can complement
39、 both the chemical and physical picture. Where the insulation 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 separa
40、tely. In the case of a filled component, the relative amounts of filler and polymeric material shall be the same in both candidate and reference material. O BSI 06-2001 Page 7 EN 60034- 18-22:2001 4 Documentation The following information shall be obtained for any proposed substitution material: a)
41、detailed chemical analysis; b) supplier and reference; c) thickness; 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
42、 reference system. 5 General substitution Drocedures The test Drocedures to be followed for any particular substitution depend on the specific O -. 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
43、 action required in respect of validation for each procedure is listed 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. - ProcedureA If the data enables the investigator to
44、establish the generic identity according to 3.3, documentation data as described in clause 4 is sufficient to accept substitution without test. - Procedure B Change requiring sealed tube test procedure (see clause 7). Change requiring a single temperature ongoing programme using a procedure, for exa
45、mple motorette procedure, selected from IEC 60034-1 8-21. Change requiring a full three-temperature test procedure as required by IEC 60034-1 8-21. - Procedure C - Procedure D O Specific component substitutions are assigned to one of the above categories in clause 6. 6 Component substitution categor

47、.1.3 Generically different IEC 60172 Procedure D applies. 6.1.2 Turn (conductor) insulation i.e. winding wire 6.1.2.1 Non-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
48、 or to one with a higher temperature class number, then; procedure A applies. b) For other substitutions; procedure D applies. 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 6031
49、7 specification part or to one with a higher temperature class number, then; procedure A applies. b) Where the substitute 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. NOTE Thermal ageing te
