Električni rotacijski stroji - 18-41. del: Električni izolacijski sistemi brez delne razelektritve (tip I), uporabljeni v električnih rotacijskih strojih, ki jih napajajo napetostni pretvorniki - Kvalificiranje in preskusi pri obvladovanju kakovosti (IEC 60034-18-1:2014/A1:2019)

Standard EN IEC 60034-18-41 definira kriterije za ocenjevanje izolacijskega sistema navitij statorja/rotorja, ki se uporabljajo v pogonih s pulzno-širinsko modulacijo (PWM) vira napetosti. Uporablja se za navitja statorja/rotorja enofaznih ali večfaznih strojev na izmenični tok z izolacijskimi sistemi za delovanje pretvornika. Standard opisuje kvalifikacijske preskuse in preskuse nadzora kakovosti (preskusi vrste in rutinski preskusi) na reprezentativnih vzorcih ali celotnih strojih, s čimer se preveri primernost stroja za delovanje z napetostnimi pretvorniki. Ta standard se ne uporablja za: - rotacijske stroje, ki jih pretvornik zgolj zažene; - rotacijske električne stroje z efektivno nazivno napetostjo ≤ 300 V; - navitja rotorja rotacijskih električnih strojev, ki delujejo pri največji vrednosti napetosti ≤ 200 V.

Overview - EN 60034-18-41:2014/A1:2019

EN 60034-18-41:2014/A1:2019 (CLC adoption of IEC 60034-18-41:2014/A1:2019) specifies qualification and quality‑control tests for partial discharge (PD) free electrical insulation systems (Type I) used in rotating electrical machines fed from voltage converters. This amendment (A1) updates definitions, routine test guidance and adds an informative Annex D describing derivation of routine withstand test voltages (including a 500 V example). The published copy includes the December 2020 corrigendum.

Key topics and technical requirements

• Scope: Applies to Type I insulation systems for converter‑fed rotating machines where PD immunity is required.
• Impulse Voltage Insulation Class (IVIC): Introduces IVIC classes (A, B, C, D, S) - manufacturer assigns IVIC based on maximum allowable peak‑to‑peak voltages related to rated voltage.
• New terms: Defines maximum allowable terminal voltage (UIVIC) and test voltage factor (TVF) used to derive routine test voltages.
• Routine tests:
  • Optional PD routine tests (clauses 11.2/11.3) recommended per agreement between manufacturer and customer; results should be recorded.
  • Mandatory minimum withstand voltage per IEC 60034‑1. For converter‑fed machines the withstand voltage may be increased according to IVIC and Annex D.
  • For machines ≤ 200 kW and U ≤ 1 kV, the 1 min test may be substituted by a 1 s test at 120% of the specified test voltage; small high‑volume machines may use an IVIC‑specified lower level if justified.
• PD test environment correction: Amendment highlights that relative humidity, temperature and altitude affect PD inception voltages and recommends use of enhancement factors to correct PDIV/RPDIV results.
• Annex D: Gives TVF values and worked example of routine withstand voltages for a 500 V rated machine; recommends that converter‑fed routine tests are not lower than equivalent line‑fed values.

Practical applications and users

This standard is essential for:

• Motor manufacturers and insulation system designers validating PD‑free Type I insulation for converter‑fed machines.
• Test laboratories and quality control teams performing PD and withstand tests.
• OEMs, specifiers and end‑users of variable‑speed drives and converter‑fed rotating machinery seeking reliable insulation performance and harmonized test procedures.
• Procurement and compliance staff ensuring products meet IVIC and routine test requirements.

Related standards

• IEC/EN 60034‑1 (Rotating electrical machines - Rating and performance) - referenced for routine withstand test baseline.
• IEC 60034‑18‑41 (base publication) - this document is the EN adoption with amendment A1.
