GSO IEC 60127-8:2021 微型熔断器 第8部分：具有特殊过流保护功能的熔断电阻器

IEC 60127-8:2018 relates to fuse resistors with particular overcurrent protection rated up to AC 500 V and/or DC 500 V for printed circuits and other substrate systems, used for the protection of electric appliances, electronic equipment and component parts thereof, normally intended to be used indoors. It does not apply to fuse resistors with particular overcurrent protection for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere. The object of this part of IEC 60127 is a) to establish uniform requirements for fuse resistors with particular overcurrent protection so as to protect appliances or parts of appliances in the most suitable way; b) to define the performance of the fuse resistors with particular overcurrent protection, so as to give guidance to manufacturers of electrical appliances and electronic equipment and to ensure replacement of fuse resistors with particular overcurrent protection by those of similar dimensions and characteristics; c) to establish uniform test methods for fuse resistors with particular overcurrent protection, so as to allow verification of the values (for example rated dissipation, functioning characteristic and rated breaking capacity values) specified by the manufacturer. This part of IEC 60127 applies in addition to the requirements of IEC 60127-1. This first edition of IEC 60127-8 cancels and replaces IEC PAS 60127-8:2014. This international standard is to be used in conjunction with IEC 60127-1. Keywords: Miniature Fuses, Fuse-Resistors, Overcurrent Protection

The standard applies in general to porcelain-housed and polymer-housed type arresters but also to gas-insulated metal enclosed arresters (GIS-arresters) solely used as d.c. bus and d.c. line/cable arresters. Arresters for voltage source converters are not covered. Arresters applied on the a.c. systems at the converter station and subjected to power-frequency voltage of 50 or 60 Hz principally without harmonics are tested as per IEC 60099-4. The arresters on a.c.-filters are tested according to this standard. Keywords: testing of gapless metal-oxide surge arrestors for HVDC converter stations

This eighth edition cancels and replaces the seventh edition published in 2009. This edition includes the following significant technical changes with respect to the previous edition: – additional information concerning thermally operated strikers; – the division of ratings, characteristics and type tests into those applicable to all fuses and those applicable to particular fuse-link types and applications; – adjustment of Series II voltages and tests to meet present North American standard system voltages and applications; – clarification of requirements for fuse-links used in surrounding temperatures above 40 °C; and – clarification of homogeneous requirements for fuse-links containing one element.

IEC 62873-1:2017 The IEC 62873 series covers available common standards intended to be used in conjunction with or for the preparation of RCD (residual current device) standards. This part of IEC 62873 defines the methodology and processes used when producing standards based on a new approach (hereafter referred to as blocks and modules) aiming at harmonizing a family of standards, thus avoiding mistakes, inconsistencies or discrepancies within this family of standards. The family of standards considered in this document consists of standards for RCCBs (Residual Current Circuit-Breakers without overcurrent protection), RCBOs (Residual Current Circuit-Breakers with overcurrent Protection), and general safety requirements for residual current operated protective devices (namely IEC 61008-1, IEC 61009-1 and IEC TR 60755).
