标准范围

IEC 60079-7:20 15规定了用于爆炸性气体环境的电气设备和防爆部件的设计、构造、测试和标记要求，其保护类型为“e”。增加安全性“e”保护类型的电气设备和防爆组件是:-保护级别“eb”(EPL“Mb”或“Gb”)；或-保护级别“ec”(EPL“Gc”)。防护等级“eb”适用于设备或防爆组件，包括其连接、导体、绕组、灯具和电池；但不包括半导体或电解电容器。防护等级“ec”适用于设备或防爆组件，包括其连接、导体、绕组、灯具和电池；并且还包括半导体和电解电容器。除非另有说明，本标准的要求适用于两种防护等级。对于“eb”级保护，本标准适用于额定电压不超过11 kV r.m.s.交流电的电气设备。或者华盛顿。对于“ec”防护等级，本标准适用于额定电压不超过15 kV r.m.s.交流电的电气设备。或者华盛顿。本标准对IEC 60079-0的一般要求进行了补充和修改。当本标准的要求与IEC 60079-0的要求相冲突时，以本标准的要求为准。本第五版取消并取代了2006年出版的第四版，构成技术修订。有关文档5.0版与先前版本之间技术变更的完整列表，请参阅文档前言。关键词:用于爆炸性气体环境的具有增加安全性“e”保护类型的电气设备和防爆部件。

IEC 60079-7:2015 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:
- Level of Protection "eb" (EPL "Mb" or "Gb"); or
- 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. 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. 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. 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. This fifth edition cancels and replaces the fourth edition published in 2006, and constitutes a technical revision. Refer to the Foreword of the document for a complete listing of the technical changes between edition 5.0 and previous edition of the document.Keywords: electrical equipment and Ex Components with type of protection increased safety "e" intended for use in explosive gas atmospheres.
