IEC 62271的本部分适用于紧凑型开关设备组件，该组件由至少一个直接连接到一个或多个其他设备或与之共享组件的开关设备组成，以确保各个设备的功能之间存在相互作用。此类组件由1.101中定义的装置组成，并设计、测试和供应作为一个单独的单元使用。设备之间的相互作用可能是由于接近、共享组件或两者的组合。组件可能仅包含空气绝缘开关设备（AIS）的组件，或AIS和气体绝缘开关设备（GIS）的组合，即所谓的混合技术开关设备（MTS），并且可以完全预制或部分组装交付。

This part of IEC 62271 applies to compact switchgear assemblies consisting of at least one switching device directly connected to, or sharing components with, one or more other devices such that there is an interaction between the functions of the individual devices. Such assemblies are made up of devices defined in 1.101 and are designed, tested and supplied for use as a single unit. The interaction between devices may be due to proximity, sharing of components or a combination of both. The assemblies may contain components of air insulated switchgear (AIS) only or a combination of AIS and gas insulated switchgear (GIS), so called mixed technology switchgear (MTS) and may be delivered entirely prefabricated or partially assembled.
