交流接触器的检测控制电路

Detection Circuit Control of AC Contacts

在交流接触器的配电回路,增设接触器检测控制电路,以达到在主触头不带电的情况下,检查接触器的动作情况,达到检测电路能正常运行的效果,并介绍了检测常用的交流接触器的两种控制电路。

In the distribution loop of AC contacts, add the detection circuit control to achieve detection move-ment of contact in the case of the main contact is not charged, can achieve the results that the detection circuit is in normal operation or not, and introduce the two control circuits that to detect AC contacts in common use.
