摘要
综合目前国内外电机智能保护器的发展现状,采用DSP作为微机保护装置的CPU,利用其片内的高速AD转换芯片把现场采集到的模拟量转换成数字量,并控制键盘输入、LCD显示和执行机构动作,弥补了传统保护器的许多缺陷,解决了对三相电机更加可靠地进行保护的问题。
In view of intelligence protector development in present situation at present domestic and foreign news dispatch motive, it uses TMS320LF2407A to take at present the microcomputer protective device CPU. It uses its internal high speed AD transformation chip to transform the simulation quantity which is gathered to the digital quantity, and control keyboard entry, the LCD demonstration and the implementing agency movement, so it has made up many flaws of the traditional protector and solved the problem on how to carry on the protection to the three-phase motor reliably.
