High-voltage switchgear and controlgear - Part 4: Handling procedures for gases for insulation and/or switching
SIST EN IEC 62271-4:2022

This part of IEC 62271 applies to the procedures for handling of gases and gas mixtures for insulation and/or switching during installation, commissioning, repair, overhaul, normal and abnormal operations and disposal at the end-of-life of high-voltage switchgear and controlgear. These procedures are regarded as minimum requirements to ensure the reliability of electric power equipment, the safety of personal working with these gases and gas mixtures and to minimize the impact on the environment. Additional requirements could be given or specified in the operating instruction manual of the manufacturer. For each gas or gas mixture, which is known to be used in electric power equipment at the date of the publication of this document, a separate annex describes specifications, handling procedures, safety measures, etc. For gases or gas mixtures not covered by these annexes the electric power equipment manufacturer should provide the information needed, following the structure of these annexes. Such gases or gas mixtures should also be described in a next edition or in amendments to this edition. NOTE 1 For the use of this document, high-voltage (HV) is defined as the rated voltage above 1 000 V. However, the term medium-voltage (MV) is commonly used for distribution systems with voltages above 1 kV and generally applied up to and including 52 kV. NOTE 2 Throughout this standard, the term "pressure" stands for "absolute pressure". NOTE 3 Reference is also made to (Cigré Brochure 802, 2020). NOTE 4 For further details on gases, e.g. ecotoxicology, also refer to the chemical database ECHA (www.echa.europa.eu), which takes the actual volume band into consideration. NOTE 5 When reference to circuit-breakers is made, only gas circuit-breakers are of interest. When vacuum circuit breakers are of interest, they are explicitly mentioned.

This document applies to all high-voltage switchgear and controlgear except as otherwise specified in the relevant IEC standards for the particular type of switchgear and controlgear. This second edition cancels and replaces the first edition published in 2007 and Amendment 1:2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: New numbering in accordance with ISO/IEC directives, Part 2 (2016) and IEEE Std. C37.100.1. 4.1.2 a) The normal service condition for indoor switchgear is limited to one range of 40 °C to -5 °C. 4.1.3 a) The normal service condition for outdoor switchgear is limited to one range of 40 °C to -25 °C. 4.2.2: The specifications from IEC 60071-2:1996 are adopted for altitude correction factors above 1 000 m. 5.2.2: Range I, the rated voltage of 40,5 kV is added Series I Table 1; Table 2 and Table 4 are updated on recommendation of the US National Committee. 6.8: New subclause added for manual operated actuators consistent with “Man Machine Interface” recommendations of IEC 60447 . 7.2.6.1:Insert the wording regarding preliminary impulses across open vacuum interrupters according to the result of IEC 17/1026/RQ. 7.3: Changed the requirement for radio interference voltage to a rated voltage level of 245 kV and above, instead of 123 kV and above. This change is based on reported positive test and service experience of utility representatives in the maintenance team of this standard. 7.5.6, Table 14: a. Introduced the distinction of parts in “OG” (oxidizing gas) or in “NOG” (not oxidizing gas) replacing the former “air” and “SF6”; b. Increased the allowable temperature rise for some parts in groups 1 and 2 of Table 14 according to IEC TR 60943; c. Expanded the definition of allowable temperature rise for categories of accessible surfaces with reference to IEC Guide 117. See also Point 15 in 7.5.6.2. 7.5.6.2: Point 5 is modified to clarify the introduction of “OG” and “NOG” gas. 7.10: Some tests were removed because the relevant test standards of IEC 60068 series were modified or withdrawn. 7.11.3: The acceptance criteria for X-radiation testing are modified to recognize higher rated vacuum interrupters. Former informative Annex H: Corrosion is deleted, the content is part of IEC TR 62271-306. New Annex J (informative): Added informative guidelines for the extension of validity of type tests New Annex K (informative): Added informative guidelines about exposure to pollution

This part of IEC 62271 applies to compact switchgear assemblies consisting of at least one switching device directly connected to, or sharing components with, one or more other devices such that there is an interaction between the functions of the individual devices. Such assemblies are made up of devices defined in 1.101 and are designed, tested and supplied for use as a single unit. The interaction between devices may be due to proximity, sharing of components or a combination of both. The assemblies may contain components of air insulated switchgear (AIS) only or a combination of AIS and gas insulated switchgear (GIS), so called mixed technology switchgear (MTS) and may be delivered entirely prefabricated or partially assembled.
