继电保护试验电源柜
- 产品详情
产品简述
GGS型试验电源柜适用于各容量发电厂及变电所。该产品是我公司依据能源部《发电厂、变电所工程和继电保护试验仪表配置定额》、 《继电保护检验条例》和电力工业部颁发《电力系统继电保护及安全自动装置反事故措施要点》的有关规定设计制造的产品。它为现场继电保护试验工作提供了可靠、稳定方便的交、直流试验电源，为提高继电保护试验工作的质量，保障人身设备安全，提供了可靠保证。
功能特点
● 交流输入采用双电源供电，通过切换开关自动转换，可保证供电的可靠性；
● 交流电源采用大容量隔离变压器，将系统电源与试验电源进行隔离。并在初级与次级之间加屏蔽层，使试验电源免受电网暂态过程和其它谐波干扰；
● 变压器采用△/y_ll接线方式。大大削弱了三次谐波，保证了电源质量；
● 直流电源可以连续平滑的调节电压，以适应不同试验项目的需要；
● 电源输入和输出均采用断路器，具有动作迅速、寿命长、过负荷自动跳闸功能；
● 交流输出装有漏电保护开关，确保试验人员安全。
