标准摘要
[中文适用范围]: 本技术规范适用于 - 电气设备中通用的陶瓷和玻璃空心绝缘子; - 陶瓷空心绝缘体,用于开关设备和控制设备中的永久气压。它们适用于室内和室外电气设备,额定电压大于 1 000 V、频率不大于 100 Hz 的交流电运行,或用于额定电压大于 1 500 V 的直流设备。本规范规定了空心绝缘子的尺寸和机械特性,这些特性对于同类型空心绝缘子的互换性至关重要。本说明书的目的不是规定电特性,因为它们取决于中空绝缘体最终形成其一部分的设备。然而,IEC 60071-1中提供的标准雷电冲击耐受电压的描述仅供分类时参考。本规范适用于洁净区或轻污染区电气设备中不要求抗震合格的空心绝缘子。对于在污染程度严重的地区以及其他特定或极端环境条件(例如地震力)的使用,可能需要改变某些尺寸。本规范涵盖的空心绝缘子有: a) 两端带有金属配件的直型空心绝缘子; b) 两端带有金属配件的锥形空心绝缘子; c) 不带金属配件的直型空心绝缘子; d) 不带金属配件的锥形空心绝缘子。空心绝缘体适用于电气设备,例如: - 断路器; - 互感器; - 避雷器; - 套管; - 电缆密封端部; - 隔离开关; - 隔离开关; ——接地开关; - 电容器。在某些情况下,空心绝缘体的设计可能会受到特定设备的其他部件(例如断路器的有源部件)的强烈影响。对于此类情况,空心绝缘子可根据此类设备的各自要求单独设计,不属于本规范的范围。注1:本规范中未规定的空心绝缘子也可应用于电气设备,具体取决于设备的具体要求。然而,如果本规范中存在类似的绝缘体,则最好使用它们。注2:空心绝缘子设计和试验的一般建议,见IEC 62155。 注3:污染区域用空心绝缘子的特性,可参考IEC 60815-1和IEC 60815-2。 [外文原描述]: IEC/TS 62371:2008(E) is a Technical Specification which applies to ceramic and glass hollow insulators intended for general use in electrical equipment; and ceramic hollow insulators intended for use with a permanent gas pressure in switchgear and controlgear. This specification specifies the dimensional and mechanical characteristics of the hollow insulator, which are essential for interchangeability of the hollow insulator of the same type. It is not the object of this specification to prescribe electrical characteristics because they are dependent on the apparatus of which the hollow insulator ultimately forms a part. However, standard lightning impulse withstand voltage which is provided in IEC 60071-1 is described only for reference for classification purpose. This specification applies to hollow insulators for use in electrical equipment in clean areas or lightly polluted areas, where seismic qualification is not required.
