产品简介
随着国民经济的飞速发展，民用和工业用电量的急剧增大，保障国家电网的安全运行工作越来越重要，在电力系统中，直流电源系统作为继电保护、自动装置、控制操作回路、灯光音响信号及事故照明等电源之用。
目前国内进行直流断路器安秒特性检测的机构和生产厂家用于直流空开安秒特性检测的设备均为固定设备，如固定的大电流电源、大型负载电阻，体积大、重量大，不便于移动检测，分析仪表均为常规仪表如电压表、电流表、示波器等，接线复杂，使用不便，不适应各变电站移动检测需要。为解决现场对直流断路器实际特性检测的问题，南澳电气推出了一种适合变电站现场使用、便于携带、自动化程度高的"NAAS-500A直流断路器安秒特性测试仪"，可以为运行维护部门提供直流保护电器动作特性的测试手段，对直流保护电器的动作特性以及级差配合进行校验，以便提高直流系统运行的可靠性，保证电网的安全可靠运行。
NAAS-500A直流断路器安秒特性测试仪是专为变电站试验、检修、维护工作而设计。满足直流断路器的超载和短路特性测试，从而提高变电站直流系统的健康水平，避免直流配电网络出现越级跳闸和引发的大面积停电事故。
