TWA25A调压开关和线组分析仪介绍

在三相电力变压器和自耦变压器的绕组电阻测量方面,TWA 标准系列提供了市场上一些技术先进的带有 LCD 显示屏的仪器。两种型号都能够通过一次性电缆连接测试六个变压器绕组,以及三相自动变压器退磁。存储的磁能在测试结束时安全自动释放。内置分接开关控制单元可实现自动测试模式,在该模式下,仪器无需操作员输入即可操作分接开关,并根据预先选择的稳定标准记录绕组电阻结果。该选项使操作员的工作变得更加容易。

两种型号均可输出 5 mA 至 30 A DC 的测试电流,用于绕组电阻测量。 TWA40D具有特殊的测试模式,用于检查三相同时并联测试的有载分接开关的同步性,其中总测试电流可升至高达40 A DC。

在非侵入式分接开关分析方面,TWA40D 具有其他优势。独特的 DVtest 方法可以在转换期间检查有载分接开关的动触点、测量转换时间、检测开路和许多其他类型的故障。它以 0.1 ms 采样率执行,同时测量分接开关电机电流,这有助于检测电机和机械问题。使用特殊的专有算法来测试通过内置串联(升压)变压器连接的分接开关。 DVtest 可以在一相上或同时在三相上进行。它还可以作为附加测试与所有分接位置的绕组电阻测试同时进行。

TWA40D 的另一个独特优势是能够同时测试三相变压器(以 YN 配置连接)的所有三相绕组电阻。这可以显着缩短总测试时间,例如,它使操作员能够在具有 33 个分接位置的分接开关上执行 33 次测量,而不是 99 次。

TWA 三相变压器绕组欧姆表的测试引线可与TRT 匝数比测试仪互换,这意味着只需将一根测试引线连接到电源变压器端子即可执行两组测试。
