引言接触器是大功率(大于25A)电路的一种电磁式开关电器,是非常重要的航空电器元件。目前,工厂仍用手工测试接触器的机械参数,对测试人员的要求高,测试结果往往因人而异,劳动强度大,测试精度和工效低。应中国航空工业总公司第三一五厂的要求,我们一起研制了航空接触器机械参数的自动测试系统,系统由计算机实现测试过程 Introduction Contactor is a high-power (greater than 25A) circuit of a magnetic switching electrical appliances, is a very important aviation electrical components. Currently, the factory still manually test the mechanical parameters of the contactor, the tester’s high requirements, the test results often vary, labor-intensive, test accuracy and low efficiency. At the request of China Aeronautical Industry Corporation No. 355 Plant, we have jointly developed an automatic test system for mechanical parameters of the air contactor. The system implements the testing process by computer
