ASTM F2249-23 断电电力线路和设备用临时接地跳线组件的运行试验方法标准规范

1.1 This specification covers the in-service inspection and electrical testing of temporary protective grounding jumper assemblies which have been used by electrical workers in the field. 1.2 This specification discusses methods for testing grounding jumper assemblies, which consist of the flexible cables, ferrules, clamps and connectors used in the temporary protective grounding of de-energized circuits. 1.3 Manufacturing specifications for these grounding jumper assemblies are in Specifications F855. 1.4 The application, care, use, and maintenance of this equipment are beyond the scope of this specification. 1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.6 The following safety hazards caveat pertains only to the test portions of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for In-Service Test Methods for Temporary Grounding Jumper Assemblies Used on De-Energized Electric Power Lines and Equipment

ASTM F855-23 用于断电电力线路和设备的临时保护接地的标准规范

1.1 These specifications cover the equipment making up the temporary grounding system used on de-energized electric power lines, electric supply stations, and equipment. 1.2 It is common practice for the users of protective grounding equipment to prepare complete instructions and regulations to govern in detail the correct use and maintenance of such equipment. 1.3 The uses and maintenance of this equipment are beyond the scope of these specifications. 1.4 These specifications for a system of protective grounding utilizing copper cables are covered in four parts, as follows: Sections Clamps for Temporary Protective Grounds 4 – 16 Ferrules for Temporary Protective Grounds 17 – 30 Cables for Temporary Protective Grounds 31 – 39 Protective Grounds (Complete Assembly With Clamps, Ferrules, and Cable) 40 – 52 1.5 Each of the four parts is an entity of itself, but is listed as a part of the system for completeness and clarification. 1.6 Currents presented in Table 1 are based upon cable melting times, as determined from equations by I. M. Onderdonk and are to used in situations involving an asymmetry value less than 20 % (X/R ≤ 1.8). See Appendix X1. 1.6.1 Currents presented in Table 2 are based upon the values from EPRI Project RP2446 Computer Program RTGC “A Desktop Computer Program for Calculating Rating of Temporary Grounding Cables” and are to be used in situations involving an asymmetry value greater than 20 % (X/R ^ 1.8), see Appendix X2. NOTE 1—Table 1 represents the clamp and assembly ratings that existed prior to this revision. Table 2 represents new ratings now required for high X/R situations. 1.6.2 See Appendix X1 and Appendix X2 for a discussion of these topics. 1.7 The values stated in Newton-Meter units are to be regarded as the standard. The values in parentheses are the inch-pound units. 1.8 The following precautionary caveat pertains to the test method portions, Sections 12 and 25 of these specifications: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1   Scope This part of IEC 62873 applies to devices equipped with screw-type terminals of copper – or of alloys containing at least 58 % of copper (if worked cold) or at least 50 % of copper (if worked otherwise), or of other metal or suitably coated metal, no less resistant to corrosion than copper and having mechanical properties no less suitable – for use with untreated aluminium conductors, or with screw-type terminals of aluminium material for use with copper or aluminium conductors. This document does not cover the use of aluminium conductors or aluminium terminals for DC applications. Flexible aluminium conductors are not covered by this document. NOTE 1 Flexible aluminium conductors are under consideration. This document cannot be used alone but it is intended to be applied together with the applicable product standard. In this document, copper-clad and nickel-clad aluminium conductors are considered as aluminium conductors. NOTE 2 In AT, AU and DE, the use of aluminium screw-type terminals for use with copper conductors is not allowed. — In AT and DE, terminals for aluminium conductors only are not allowed; — In ES, the use of aluminium conductors is not allowed for final circuits in household and similar installations e.g...

IEC 60269-2:2013 provides supplementary requirements for fuses for use by authorized persons and are generally designed to be used in installations where the fuse-links are accessible to, and may be replaced by, authorized persons only. Fuses for use by authorized persons according to the following fuse systems also comply with the requirements of the corresponding subclauses of IEC 60269-1, unless otherwise defined in this standard. This standard is divided into fuse systems, each dealing with a specific example of standardized fuses for use by authorized persons: - Fuse system A: Fuses with fuse-links with blade contacts (NH fuse system), - Fuse system B: Fuses with striker fuse-links with blade contacts (NH fuse system), - Fuse system C: Fuse-rails (NH fuse system), - Fuse system D: Fuse-bases for busbar mounting (NH fuse system), - Fuse system E: Fuses with fuse-links for bolted connections (BS bolted fuse system), - Fuse system F: Fuses with fuse-links having cylindrical contact caps (NF cylindrical fuse system), - Fuse system G: Fuses with fuse-links with offset blade contacts (BS clip-in fuse system), - Fuse system H: Fuses with fuse-links having 'gD' and 'gN' characteristic (class J and class time delay and non time delay fuse types), - Fuse system I: gU fuse-links with wedge tightening contacts, - Fuse system J: Fuses with fuse-links having 'gD class CC' and 'gN class CC' characteristics (class CC time delay and non-time delay fuse types), - Fuse system K: gK fuse-links with blade for bolted connections - High fuse-link ratings from 1 250 A up to 4 800 A (master fuse-links). This fifth edition of IEC 60269-2 cancels and replaces the fourth edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: 1. fuse systems A and B: modified values for the power dissipation of NH aM fuse-links; 2. fuse systems A and B: introduction of dimension r for NH fuse-links; 3. addition of new fuse system K: gK fuse-links with contacts for bolted connections. Key Words: fuse systems A to K, requirements for fuses
