摘要
风洞中交流电机调速器、直流电机调速器及继电器等动力设备运行时将产生强干扰。它们从电网、信号线、地线进入测试系统。抑制干扰也从电源系统、地线、信号线等方面采取措施,通过隔离、屏蔽、滤波、接地等方法,在软件上采取数字滤波。
When the power machines of wind-tunnel work such as alternating-current machine governor and direct-current machine governor and relay, they will bring about strong interference.The interference go into the test system through electrified wire netting,signal wire and ground wire.We take measure for inhibition interference by power supply system and signal wire and ground wire etc.Using digital filter in software through isolate,screen,filter and ground connection etc.
