Using logical analysis to identify and narrowing the scope of the fault

Maintenance simple electrical control circuit,to each of the electrical components one by one to inspect each wire,usually can quickly find the point of failure.But for complex circuit,often have hundreds of components,thousands of wire,if to examine' method,not only need to spend a lot electrical motor of time,but also easy to leak check.If in this case,according to the circuit diagram,using logical analysis,make concrete analysis of the fault phenomena,to draw suspicious range,improve the maintenance of the targeted,can receive motor run capacitor the accurate and fast effect.

Analysis circuit first,from the perspective of the main circuit,realize the industrial machinery using a few moving parts and electric motor drive,what are related to each motor electrical components,what control adopted,electricalmotor1.blogspot.com and then according to the electric main circuit of the circuit element used text symbols,sex and control requirements,find the corresponding control control circuit.On this basis,combining with the failure phenomena and circuit principle of asynchronous motor work,careful analysis of the screen,can quickly determine the possibility of failure.When fault suspicious range larger,don't need to check step by step,step by step then can be in the range of failure in a check of the intermediate links,to judge the fault occurred where on earth is part of thus narrowing the scope of failure,improve the inspection speed.
