《GB/T 14824-2008高压交流发电机断路器》由TC65(全国高压开关设备标准化技术委员会)归口,主管部门为中国电器工业协会。
本标准代替GB/T 14824-1993《发电机断路器通用技术条件》。
本标准规定了高压交流发电机断路器的使用环境条件、术语和定义、额定值和要求的能力、设计和结构、型式试验、出厂试验、选用导则、现场交接试验等。
本标准适用于安装在发电机和升压变压器之间,额定电压12kV~36kV,额定频率50Hz的所有高压交流发电机断路器。
安装在发电机和发电厂厂用电变压器之间的断路器也可参照本标准。
本标准与GB/T 14824-1993的主要差别有:
―――补充了额定电压15kV及相关要求;
―――修改了额定绝缘水平,取消了六氟化硫气体零表压下耐受工频电压的要求;
―――修改了额定短路持续时间;
―――修改了机械操作试验的操作循环次数;
―――修改了系统源故障关合、开断试验和失步关合、开断试验的试验方式的代号;
―――提高了失步非对称开断试验时的直流分量百分数;
―――明确了电寿命试验要求;
―――增加了“励磁电流开、合试验”和“外壳的验证试验和受压系统的试验”;
―――增加了第8章“选用导则”,以指导发电机断路器的使用;
―――增加了第9章“与询问单、标书和订单一起提供的资料”;
―――增加了第10章“运输、储存、安装、运行和维护规则”;
―――增加了第11章“安全性”;
―――增加了“附录A 发电机断路器应用例子”,为计算与发电机断路器的关合、开断和开合性能相关的短路电流、持续电流等提供参考。
本标准应与GB/T 11022-1999一起使用,除非本标准中另有规定,本标准参照GB/T 11022-1999。为了简化相同要求的表示,本标准的章条号与GB/T 11022-1999所用的相同。对这些章条内
容的补充和/或修改在同一引用标题下给出,而附加的条款从101开始编号。
Scope
This standard specifies the operating environment conditions, terms and definitions, rated values and required capabilities, design and structure, type test, factory test, selection guidelines, on-site handover test, etc. of high-voltage alternator circuit breakers. This standard applies to all high-voltage alternator circuit breakers installed between generators and step-up transformers with a rated voltage of 12kV to 36kV and a rated frequency of 50Hz. The circuit breaker installed between the generator and the service transformer of the power plant can also refer to this standard.
