控制电器触点接触可靠性试验装置

Test Device for Contact Reliability of Electrical Apparatus with Contacts

讨论了一种用于交直流触点可靠性试验的装置,该装置采用工业控制计算机作为控制主机,试验装置可以同时控制16台试品线圈通断电操作,可以同时监测64对触头的接触和打开情况。试品、负载均交直流兼容,对于试品的每一次操作,试验装置可以监测试品的吸合时间和释放时间是否在允许的范围之内,可以监测试品的触头是否接触良好。如果有试品发生失效,试验装置可以记录存储失效发生时的试验数据,试验的数据是不会因为关机或断电而丢失,介绍了试验装置的性能、软硬件结构。

The paper discusses a king of test device used in AC and DC contactor reliability,and device adopt IPC as the control computer,it can control 16 sample winding on-off power,and monitor 64 pairs of contacts on-off at the same time,and no matter the voltage of sample and load is AC or DC.In every time test,device can monitor pickup time and release time whether in permission scope,and test contact whether in well.If sample is failure,all test data can be taken and preserved ever that test power is cut off unexpectedly during test process.It is introduced about performance,hardware and software of device too.
