一种能快速判断电力载波机收信支路故障的装置

Device for quickly finding failures in receiving signal branch of PLC

针对电力载波机收信支路上发生的故障难以查找的问题,文章以ZBD-2B型载波机发信支路为基础,改装、制作了一种测试装置。并就目前最常用到的4种电力载波机型,分别介绍了如何运用装置对它们的收信支路进行测试和故障查找。实践证明,该方法简便、易行,适于推广。

It is comparatively difficult to find out the failures occurred in the signal receiving branch circuit of PLC.To find out the failures,a testing device is made,which is based on the carrier of Model ZBD-2B.This device is used to test the receiving signal branch and seek the faults on 4 types of PLC which used in common.The method and testing results are introduced and analyzed in this paper.The results show that this method is easy to realize and effective to apply.In addition,the device and method are suitable for popularization.
