标准范围

IEC 62772:2016适用于复合空心站柱绝缘子，该复合空心站柱绝缘子由树脂浸渍纤维制成的承重绝缘管（芯）、绝缘填充材料（例如固体、液体、泡沫、加压或非加压气体）、由聚合材料（例如硅树脂或乙烯-丙烯）制成的外壳（绝缘管外部）和绝缘管末端的金属固定装置组成。本标准中定义的复合空心站柱绝缘子用于室外和室内环境下的变电站，额定交流电压大于1 000 V，频率不大于100 Hz，或用于额定电压大于1 500 V的直流系统。本标准的目的是:-定义所使用的术语；-规定测试方法；-规定验收标准。除热机械试验外，本标准中的所有试验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体最终可能形成其一部分的设备特性的测试。

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.
