During the inspection of the workshop recently, it was found that the capacitors in the compensation cabinets in the workshop were bulging and the wiring was melted, so a special inspection of the capacitors was carried out. Because there are more power distribution cabinets and capacitors involved, the replacement time will be sooner or later, so it cannot be all One-time replacement requires that each capacitor in the electrical cabinet be checked once. Some can be seen directly that it needs to be replaced, and some are more concealed and need to be detected. So here is the method of capacitance detection. First of all, the simplest method of visual inspection, the most common is the capacitor bulge, bursting of the shell, this kind of obvious, will undoubtedly be broken, I will not go into more details here. Secondly, for those with replacement records, check the previous replacement records. The capacitors also have service life. Although the service life of each capacitor varies, it is recommended to replace all the capacitors when the service life of the capacitor expires. As for the service life of the capacitor , Generally, about five years is the time limit for replacement. After a long time, even if there is no problem, the performance has declined.
