12、ollowing definitions apply for the purpose of this standard:3.101 Switchgear and controlgearA general term covering switching devices and their combination with associated control,measuring,protective and regulating equipment,also assemblies of such devices and equip-ment with associated interconnec
13、tions,accessories,enclosures and supporting structures(IEV441-11-01).3.102 Metal-enclosed switchgear and controlgearSwitchgear and controlgear assemblies with an external metal enclosure intended to beearthed and complete except for external connections(IEV 441-12-04).NOTB-The metal-enclosed switchg
14、ear and controlgear is subdivided into three types:metal-clad switchgear and controlgear;-compartmented switchgear and controlgear(with one or more non-metallicpartitions):-cubicle switchgear and controlgear.3.102.1 Metal-clad switchgear and controlgearMetal-enclosed switchgear and controlgear in wh
15、ich components are arranged in separatecompartments with metal partitions intended to be earthed.NOTES1 This term applies to metal-enclosed switchgear and controlgear with metal partitions providing thedegree of protection included in table 1(or higher)and having separate compartments at least for t
16、hefollowing components:a)each main switching device;b)components connected to one side of a main switching device,for example feeder circuit;c)components connected to the othor side of tho main switching device,for example busbars:where morethan ohe set of busbars is provided,each set being in a sep
17、arate compartment.2 Metal-enclosed switchgear and controlgear having metal partitions and meeting all the requirements ofnote 1,may utilize an insulating shutter barrier as a part of tho shutter arrangement,the combination ofwhich provides the degree of protection included in table 1(or higher)and s
