带变压器的复合中空核心站后绝缘子 电压大于1000 V 直流电压电压大于1 500 V.定义 测试方法和验收标准

[中文适用范围]： “本国际标准适用于由树脂浸渍纤维制成的承载绝缘管（芯）和绝缘填充材料（例如固体@液体@泡沫@气体？C加压或未加压）@外壳组成的复合空心电站支柱绝缘子。本标准定义的复合空心站柱式绝缘子一般用于以下变电站： @室外和室内环境@在额定交流电压大于1000V且频率不大于100Hz下运行或在额定电压大于1500V的直流系统中使用。本标准的目的是： ?C 定义所使用的术语； ?C 规定测试方法； ?C 规定验收标准。本标准中除热机械测试外的所有测试均在正常环境温度下进行。本标准没有规定可能是复合空心站柱绝缘子最终可能形成的设备特征的测试。该领域需要进一步的技术投入。注 1：“加压”是指大于 0@05 MPa (0@5 bar) 表压的永久气体或液体压力。该气体可以是干燥空气或惰性气体，例如六氟化硫、氮气或这些气体的混合物。注 2：“未加压”是指小于或等于 0@05 MPa (0@5 bar) 表压的气体或液体压力。 ” [外文原描述]： IEC 62772:2016 applies to composite hollow core station post insulators consisting of a load-bearing insulating tube (core) made of resin impregnated fibres an insulating filler material (e.g. solid, liquid, foam, gaseous pressurized or unpressurized), a housing (outside the insulating tube) made of polymeric material (for example silicone or ethylene-propylene) and metal fixing devices at the ends of the insulating tube. Composite hollow core station post insulators as defined in this standard are intended for general use in substations in both, outdoor and indoor environments, operating with a rated AC voltage greater than 1 000 V and a frequency not greater than 100 Hz or for use in direct current systems with a rated voltage greater than 1 500 V. The object of this standard is: - to define the terms used; - to prescribe test methods; - to prescribe acceptance criteria. All the tests in this standard, apart from the thermal-mechanical test, are performed at normal ambient temperature. This standard does not prescribe tests that may be characteristic of the apparatus of which the composite hollow core station post insulator ultimately may form a part.
