Welded composite enclosures of cast and wrought aluminium alloys for gas-filled high-voltage switchgear and controlgear

Welded composite enclosures of cast and wrought aluminium alloys for gas-filled high-voltage switchgear and controlgear

This standard applies to welded composite enclosures of cast and wrought aluminium and aluminium alloy enclosures pressurized with dry air, inert gases, for example sulphur hexafluoride or nitrogen or a mixture of such gases, used in indoor or outdoor installations of high-voltage switchgear and controlgear with rated voltages of 72,5 kV and above, where the gas is used principally for its dielectric and/or arc-quenching properties. The enclosures comprise parts of electrical equipment not necessarily limited to the following examples: circuit-breakers, switch-disconnectors, disconnectors, earthing switches, current transformers, voltage transformers, surge arrestors, busbars and connections. The scope covers also pressurized components such as the centre-chamber of live tank switchgear and controlgear, gas-insulated current transformers, etc.

SIST EN IEC 62271-207:2024

IEC 62271-207:2023 applies to - gas-insulated switchgear (GIS) assemblies - for alternating current of rated voltages above 52 kV complying with IEC 62271-203, and - for direct current of rated voltages including and above 100 kV, - for indoor and outdoor installations, including their supporting structures, - AC metal-enclosed switchgear and controlgear assemblies for rated voltages above 1 kV and up to and including 52 kV complying with IEC 62271-200, ground or floor mounted, intended to be used under seismic conditions, and - AC solid-insulation enclosed switchgear and controlgear assemblies for rated voltages above 1 kV and up to and including 52 kV complying with IEC 62271-201, ground or floor mounted, intended to be used under seismic conditions. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. It also cancels and replaces, through merging, the first edition of IEC TS 62271-210 published in 2013. This edition includes the following significant technical changes with respect to the previous edition: a) modification of the minimum voltage rating from 52 kV to above 1 kV in order to include medium voltage equipment previously being within IEC TS 62271-210 scope; b) further harmonisation of qualification procedures with the revised IEEE Std 693-2018 [1], Annex A and Annex P, including 1) matching this document's required response spectra with IEEE Std 693-2018 performance level spectra and IEC TS 62271-210 spectra, 2) addition of a step-by-step procedure assisting the user of this document to select an appropriate seismic qualification level combining seismic integrity with cost-effective design, 3) addition of analytical earthquake component combination techniques, and 4) reference to publicly available accelerograms specially developed to match the IEEE Std 693-2018 spectra for testing and analysis purposes, since this document and IEC TS 62271-210 spectra are identical in shape with IEEE Std 693 spectra. c) various enhancements of test procedures; d) addition of minimum contents for seismic qualification reports; e) scope extended to cover DC GIS including and above 100 kV.

High-voltage switchgear and controlgear - Part 105: Alternating current switch-fuse combinations for rated voltages above 1 kV up to and including 52 kV
SIST EN IEC 62271-105:2024

IEC 62271-105:2021 is available as IEC 62271-105:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62271-105:2021 applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches composed of switches or switch-disconnectors and current-limiting fuses designed so as to be capable of - breaking, at the rated voltage, any current up to and including the rated short-circuit breaking current; - making, at the rated voltage, circuits to which the rated short-circuit breaking current applies. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the document has been updated to be in alignment with the second edition of IEC 62271-1:2017; - rated TRV has been removed (TRV is only a test parameter), as in the latest revision of IEC 62271-100; - differentiation has been introduced between requirements expressed for fulfilling the function expected from a switch-fuse combination, from requirements only relevant when the function is performed by a stand-alone device. The goal is to avoid duplication or conflicts of requirements with a standard dealing with assemblies, when the function is implemented within such an assembly.

High-Voltage switchgear and controlgear - Insulating pressurised partitions for gas filled metal enclosures
SIST EN 50089:2023

This document applies to pressurized partitions used in indoor and outdoor installations of high-voltage AC and DC switchgear and controlgear with rated voltages (Ur) above 1 kV AC / 1,5 kV DC and with design pressure higher than 300 kPa, where the gas is used principally for its dielectric and/or arc-quenching properties. The partitions comprise pressurized barriers in electrical equipment not necessarily limited to the following examples: - circuit-breakers; - switch-disconnectors; - disconnectors; - earthing switches; - current transformers; - voltage transformers; - surge arresters; - busbars and connections; - cable connections/terminations; - cable bushings. Partitions which are only pressurized from one side are also covered. 1 kV AC / 1,5 kV DC means it is valid for the apparatus applied and where the partitions are installed; however, the application of voltages below 1 kV AC / 1,5 kV DC as in, for example, current and voltage transformers are not excluded. This document does not apply to high voltage bushings (see EN 60137, EN 61462 and EN 62155).

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.
