Product Introduction

变压器有载分接开关测试仪是根据中华人民共和国电力行业标准之高电压测试设备,通用技术条件DL/T846、8-2004设计,可以满足《电力设备交接和预防性试验规程》中,要求检查有载分接开关的动作顺序,测量切换时间等要求。可实现对有载分接开关的过渡时间、过渡波形、过渡电阻、三相同期性等参数的精确测量,是测试有载分接开关的理想设备。(用户是调容的有载开关请提前告知)

Performance characteristics

①.  测试Y0  Y  △型变压器,阻值不用换算直接显示;

②.  数据分析人性化,可以自动的找出波形中间的故障,并做记号;

③.  波形的显示是根据采样回的数据自动调整阻值和时间的幅度;

④.  △型变压器可以显示三相同期性;

⑤.  可以带绕组或不带绕组进行测试;

⑥.  四端接线方式,提供高精度电阻测量,且无需导线补偿;

⑦.  在测试中间可以连续测试,节省变压器停电的时间;

⑧   仪器可以生存word报告,方便数据的管理和查询;

⑨.  仪器由小型的计算机控制,外配800×480彩色液晶触摸屏,高速打印机,支持外挂鼠标,操作方便;

⑩.  仪器内部可以自动保存1000组数据,也可以外接U盘保存。
