《GB/T 7595-2008运行中变压器油质量》由524(中国电力企业联合会)归口,主管部门为中国电力企业联合会。
本标准代替GB/T 7595-2000《运行中变压器油的质量标准》。
本标准规定了运行中变压器油和断路器油应达到的质量、检验周期。
本标准适用于充入电气设备的矿物变压器油和断路器油在运行中的质量监督 发电机用油可参考使用。
本标准与GB/T 7595-2000相比,主要修改内容为:
―――在范围中增加了发电机用油可参考使用要求,扩大了标准的适用范围。明确了不适用于在电
缆或电容器中用作浸渍剂的矿物油;
―――对原标准的规范性引用文件进行了删减和增加;
―――增加了第3章术语定义章节;
―――规定了样品采集方法按照GB/T 7597-2007执行条款;
―――修改了运行中变压器油质量标准;
―――增加了析气性和带电倾向质量指标;
―――增加了析气性和带电倾向检验方法要求;
―――取消了原标准中对新超高压变压器油验收要求的条款;
―――修改了原标准中对新断路器油验收要求的条款;
―――修改了运行中断路器油质量标准;
―――修改了原标准中设备电压等级;
―――保留了原标准11项质量要求;
―――删除原标准中油中溶解气体组分含量的要求,明确按照GB/T 17623 和GB/T 7252要求
执行;
―――删除原标准中变压器油的产品牌号;
―――增加了资料性附录A最低冷态投运温度(LCSET)下变压器油的最大黏度、最高倾点与原标准
牌号的对应关系;
―――保留了原标准中的附录B不同电极形状及操作方法对击穿电压测定值的影响;
―――保留了原标准中的附录C运行中变压器油的防劣化措施;
―――参考了GB 2536《变压器油》强制性国家标准的修订稿(2007征求意见稿)和IEC 60296:2003《电工流体 变压器和开关用的未使用过的矿物绝缘油》。


Scope

This standard stipulates the quality and inspection cycle that transformer oil and circuit breaker oil should achieve during operation. This standard is applicable to the quality supervision of mineral transformer oil and circuit breaker oil filled in electrical equipment during operation, and oil for generators can be used as a reference. This standard does not apply to mineral oils used as impregnating agents in cables or capacitors.
