标准摘要
[中文适用范围]: GB/T 7672 的本部分规定了温度指数180, 浸漆玻璃丝包铜扁线和浸漆玻璃丝包2级漆膜厚度漆包铜扁线的要求。 注:对于此类绕组线,热冲击试验不适用, 热冲击温度未加规定, 因此无法规定基于温度指数和热冲击温度要求的等级。 漆包线应基于下列之一的标准, 并应由供需双方协商确定: ——GB/T 7095.3 漆包扁绕组线 第3部分: 155级聚酯漆包铜扁线; ——GB/T 7095.4 漆包扁绕组线 第3部分: 180级聚酯亚胺漆包铜扁线; ——GB/T 7095.6 漆包扁绕组线 第3部分: 200级聚酯或聚酯亚胺符合漆包铜扁线; ——IEC 60317-30 特种绕组线标准 第30部分:220级聚酰亚胺漆包铜扁线。 所使用的漆包线, 其最低热级应为155. 浸漆玻璃丝包线的温度指数取决于使用的浸渍漆种类。浸渍玻璃丝的浸渍漆宜具有最低180的温度指数。 绕包层厚度分为四种: ——GL1:在裸导体上绕包单玻璃丝; ——GL2:在裸导体上绕包双玻璃丝; ——Grade2 GL1: 在2级漆膜厚度漆包线上绕包单玻璃丝; ——Grade2 GL2: 在2级漆膜厚度漆包线上绕包双玻璃丝; 玻璃丝包层可为: a) 单玻璃丝包; b) 双玻璃丝包, 两层玻璃丝包方向相反。 本部分规定的导体标称尺寸范围为: ——宽边尺寸:最小2.00mm, 最大16.00mm; ——窄边尺寸:最小0.80mm, 最大5.60mm; 宽边尺寸和窄边尺寸的组合以及宽边尺寸的比值见GB/T 7672.1-2008的规定。 [外文原描述]: IEC 60317-31:1990 specifies the requirements of glass-fibre wound, polyester or polyesterimide varnish-treated, bare or grade 2 enamelled rectangular copper winding wire, temperature index 180. NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified. The enamelled wire shall be based on one of the following standards and shall be agreed between purchaser and supplier. - IEC 60317-16:1990, Specifications for particular types of winding wires - Part 16: Polyester enamelled rectangular copper wire, class 155 - IEC 60317-28:1990, Specifications for particular types of winding wires - Part 28: Polyesterimide enamelled rectangular copper wire, class 180 - IEC 60317-29:1990, Specifications for particular types of winding wires - Part 29: Polyester or polyesterimide overcoated with polyamide-imide enamelled rectangular copper wire, class 200 - IEC 60317-30:1990, Specifications for particular types of winding wires - Part 30: Polyimide enamelled rectangular copper wire, class 220 When an enamelled wire is used, it must have a minimum class of 155.
