摘要
运用ARM S3C2410s微处理器,针对变压器局部放电产生的超声波信号特征设计了一种变压器局部放电信号采集系统。该系统由超声波预处理电路和基于S3C2410s的信号采集、图形显示、键盘操作和数据存储等功能模块组成,具有速度快、结构简单、经济、方便携带等优点。测试表明:该系统能可靠地采集处理变压器局部放电超声波信号,准确地反映信号的大小、频率及波形。
A partial discharge acquisition system in power transformer was designed based on ARM S3 C2410s, which was used to acquire PD ultrasonic. The system＇s function consists of analog signal pretreatment circuit, data acquisition, display of graphics, keyboard control and data storage. It is with the excellence of high speed, simple structure, convenient for carry, etc. The feasibility and accuracy of the system is validated by examination.
