Wing gate: inverted gate is in addition to the wing gates, swing gates, another commonly used gates, to help us better grasp inverted gate operation, we have to look back brake specific protection and automatic devices operating principles: protection and automatic devices Operating principles: (a) equipment is not allowed to run without protection. Transformers and important line shall run without primary protection. Before power equipment, protection and automatic device should be complete, correct the setting value, drive test well plate in accordance with the regulations put in place. (2) switching operation after a power outage or equipment, if no special requirements, generally do not operate to protect or exit platen. If switching operation will affect the working conditions of some protection or cause changes in the way runs thus undermining the principle of protection of certain other cases, it may cause malfunction, you must first disable the protection. (3) protection and automatic device inputs, you should first cast AC power (current, voltage), Rear DC power supply, check the device is working properly and then put into export tripping plate (should be prevented from touching the shell Misoperation). Special requirements such as protection and automatic operation of the device operates only uninterrupted power supply to the platen. Otherwise, the reverse order of.
