交流电压大于1000V和直流电压大于1500V的复合空心站用支柱绝缘子.定义、试验方法和验收标准

[中文适用范围]： This document, which is an International Standard, applies to composite hollow core station post insulators consisting of a load-bearing insulating tube (core) made of resin impregnated fibres, 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 1000 V and a frequency not greater than 100 Hz or for use in direct current systems with a rated voltage greater than 1500 V DC. The object of this document is: - to define the terms used; - to specify test methods; - to specify acceptance criteria. All the tests in this document, apart from the thermal-mechanical test, are performed at normal ambient temperature. This document does not specify tests that are characteristic of the apparatus of which the composite hollow core station post insulator ultimately may form a part (e.g. disconnector switch, reactor support, HVDC valves). -Further technical input is required in this area. NOTE 1 "Pressurized" means a permanent gas or liquid pressure greater than 0.05 MPa (0.5 bar) gauge. The gas can be dry air or inert gases, for example sulphur hexafluoride, nitrogen, or a mixture of such gases. NOTE 2 "Unpressurized" means a gas or liquid pressure smaller than or equal to 0.05 MPa (0.5 bar) gauge. [外文原描述]： IEC 62772:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62772:2023 applies to composite hollow core station post insulators consisting of a load-bearing insulating tube (core) made of resin impregnated fibres, insulating filler material (solid, liquid, gaseous – pressurized or unpressurized), a housing (outside the insulating tube) made of polymeric material (for example silicone or ethylene-propylene) and 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 DC. The object of this document is: - to define the terms used; - to specify test methods; - to specify acceptance criteria.
