摘　　要：测试系统是获得信息的电子设备,由于干扰的普遍存在,任何测试结果总是达不到百分之百的准确度,严重的干扰甚至会影响测试系统的正常工作,因此,在设计制造及使用测试系统时,干扰成为不可回避的重要问题。该文从干扰概念出发,针对发电机性能测试过程中的各种干扰问题,进行深入研究和分析,给出一种新型抗干扰滤波电路的设计方案,并通过Multisim9软件仿真技术模拟实验,证明了其抗干扰效果的确切性及经济实用性。Testing systems are electronic equipment to collect information.Because of the universal disturbance,the testing results are not absolutely exact,and serious disturbances even interfere the normal work.Therefore,when constructing and using the testing system,disturbance is the important problem that could not be evaded.The paper,aiming at the different problems in generator property testing,launches the analysis and study to give a new plan for the design of the anti-interference circuit.Then the anti-interference tested in the simulation experiment with Multisim9 software is proved to be in effect and has economic practicality.
