电器设备温升试验数字化测量预测系统研究

摘要

传统的温升试验系统的测量和记录设施智能化低,不能完整记录试验全过程数据,研究了一个温升试验数字化测量分析系统,该系统实现温升数据全过程记录,数据采样、处理精度高,提出了一套稳定温升预测分析算法,通过通流后1~3倍时间常数内的温升数据,做出符合精度要求的稳定温升预测,可节约大量研究性试验的时间.经试验论证,系统满足电器设备研究性试验和型式试验的要求.%The traditional equipment of temperature-rising test has low intelligentized capability in measurement and recording. The system cannot record data during test process completely to meet the demands for follow-up researching. The paper studied a measuring system of temperature-rising test to realize the whole process record and the high accuracy data sampling and disposing, and put forward the stable predic-tion algorithm to estimate the future value of temperature rise with the temperature-rising data during the period of one to three times of time constant, which saved a large number of research test time. Experimental results show that the system meets the requirements of electrical equip-ment of research tests and type tests.
