在热力装置动态过程测试记录时经常使用多笔快速记录仪(电子自动电位差计),它可以同时记录几个频率低於1周/秒的电信号随时间变化的关系,给自动检测和调节系统的调试、整定工作带来了很大的方便。目前,火力发电厂的热力过程检测与自动调节系统中大部份采用DDZ—Ⅱ型电动单元组合仪表,系统中测量和联络信号均乐用0—10mA统一的电流制信号,这为多笔快速记录仪的应用提供了有利的条件。电厂热力装置动态过程测试中常用的国产快速记录仪有LZ—6型三笔记录仪、XW
In the thermodynamic device dynamic process test records often use multiple rapid recorder (electronic automatic potentiometer), which can simultaneously record several less than 1 week / second frequency of electrical signals over time relationship to automatically detect and adjust System debugging, tuning work has brought great convenience. At present, the thermal power plant thermal process detection and automatic adjustment system most of the DDZ-Ⅱ-type electric unit combination meter, the system measurement and contact signals are used 0-10mA current unity of the current signal, which is more than a quick Logger application provides favorable conditions. Power plant thermodynamic device commonly used dynamic process test rapid recorder with LZ-6 type three pen recorder, XW
