IEC/IEEE 60079-30-2:2015 易爆气体.第30-2部分:电阻丝加热.设计、安装和维护应用指南

This part of IEC 60079 provides guidance for the application of electrical resistance trace heating systems in areas where explosive atmospheres may be present, with the exclusion of those classified as requiring EPL Ga/Da (traditional relationship to Zone 0 and Zone 20 respectively). This standard also provides guidance for explosive atmospheres incorporating the Division method of area classification that may be applied by some users of this standard. NOTE Information on the Division method is given in NFPA 70 and CSA C22.1. It provides recommendations for the design, installation, maintenance and repair of trace heating systems including associated control and monitoring equipment. It does not cover devices that operate by induction heating, skin effect heating or direct pipeline heating, nor those intended for stress relieving.

IEC 60079-7:2015 易爆环境.第7部分：增加安全性的"e"型防护电气设备

"This part of IEC 60079 specifies the requirements for the design@ construction@ testing and marking of electrical equipment and Ex Components with type of protection increased safety ""e"" intended for use in explosive gas atmospheres. Electrical equipment and Ex Components of type of protection increased safety ""e"" are either: a) Level of Protection ""eb"" (EPL ""Mb"" or ""Gb""); or b) Level of Protection ""ec"" (EPL ""Gc"") Level of Protection ""eb"" applies to equipment or Ex Components@ including their connections@ conductors@ windings@ lamps@ and batteries; but not including semiconductors or electrolytic capacitors. NOTE 1 The use of electronic components@ such as semiconductors or electrolytic capacitors@ is excluded from Level of Protection ""eb"" as expected malfunctions could result in excessive temperatures or arcs and sparks if the internal separation distances were not applied. It is not generally practical to maintain those separation distances and maintain the function of the electronic component. Level of Protection ""ec"" applies to equipment or Ex Components@ including their connections@ conductors@ windings@ lamps@ and batteries; and also including semiconductors and electrolytic capacitors. NOTE 2 The use of electronic components@ such as semiconductors or electrolytic capacitors@ is permitted in Level of Protection ""ec"" as these are evaluated under both normal conditions and regular expected occurrences@ and are not likely to result in excessive temperatures or arcs and sparks. As the requirements for separation distances are not applied to the internal construction@ commercially available electronic components are generally suitable if the external separation distances comply. The requirements of this standard apply to both Levels of Protection unless otherwise stated. For Level of Protection ""eb""@ this standard applies to electrical equipment where the rated voltage does not exceed 11 kV r.m.s.@ a.c. or d.c. For Level of Protection ""ec""@ this standard applies to electrical equipment where the rated voltage does not exceed 15 kV r.m.s.@ a.c. or d.c. NOTE 3 Short circuit currents flowing through increased safety connections of mains circuits are not considered to create a significant risk of ignition of an explosive gas atmosphere due to movement of connections as a result of mechanical stresses created by the short circuit current. Normal industrial standards require that the effects of short time high currents on the security of connections be considered. The presence of the explosive gas atmosphere does not adversely affect the security of the connection. NOTE 4 Any short term thermal excursions that occur as a result of electrical current excursions above normal rated currents@ such as those that occur during the starting of motors@ are not considered to create a significant risk of ignition of an explosive gas atmosphere due to the relatively short duration of the event and the convection that occurs during the event. NOTE 5 High-voltage connections and associated wiring (above 1 kV) can be susceptible to increased partial discharge activity that could be a source of ignition. Increased spacings to earthed surfaces or other connections and provision of suitable high-voltage stress relief for the terminations are typically provided. This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0@ the requirement of this standard takes precedence."

IEC TS 60079-39:2015 爆炸性大气环境. 第39部分: 带电子控制火花持续时间限制的本安型系统

This Technical Specification specifies the construction, testing, installation and maintenance of Power-i apparatus and systems which utilise electronically controlled spark duration limitation to maintain an adequate level of intrinsic safety. This Technical Specification contains requirements for intrinsically safe apparatus and wiring intended for use in explosive atmospheres and for associated apparatus intended for connection to intrinsically safe circuits entering such atmospheres. This Technical Specification excludes the level of protection "ia" and the use of software- controlled circuits. This Technical Specification applies to electrical equipment utilising voltages not higher than 40 V d.c. and a safety factor 1,5 for Groups IIB, IIA, I and III. It is also applicable to Group IIC "ic" apparatus with a safety factor 1,0. Group IIC "ib" apparatus with a safety factor 1,5 are restricted to voltages up to 32 V d.c. This type of protection is applicable to electrical equipment in which the electrical circuits themselves are incapable of causing an explosion of the surrounding explosive atmospheres. This Technical Specification is applicable to intrinsically safe apparatus and systems which utilise electronically controlled spark duration limitation with the aim of providing more electrical power while maintaining an adequate level of safety. This Technical Specification is also applicable to electrical equipment or parts of electrical equipment located outside hazardous areas or protected by another type of protection listed in the IEC 60079 series, where the intrinsic safety of the electrical circuits in explosive atmospheres depends on the design and construction of such electrical equipment or parts of such electrical equipment. The electrical circuits located in the hazardous area are evaluated for use in such locations by applying this Technical Specification. This Technical Specification supplements and modifies the requirements of IEC 60079-0, IEC 60079-11, IEC 60079-14, IEC 60079-17 and IEC 60079-25.
