Austin Circuit Breaker Maintenance Tips. In order to first begin proper maintenance of any circuit breaker, it must first be switched off before then being isolated from both sides by opening the electrical isolator. From there, the breaker should then be electrically operated locally and remotely before then being mechanically operated locally, as this type of operation allows the breaker itself to be much more reliable by removing any and all coating that has developed between sliding surfaces.
Here are some of the most common circuit breaker maintenance tips.
*For a bulk oil circuit breaker, one of the first things to do is check contact burning. If this is found to be very light, you will need to remove the burn heads before then polishing the surface. On the other hand, if the burning is heavy, both the tips and arcing ring should be replaced. Additionally, the extinguishing chamber should be checked as well, removing it from the breaker unit. Wash the chamber by insulating oil. If any severe burning is indicated, the chamber should be dismantled and all burning or damaged parts should be replaced. Next, clean and lubricate the CB mechanism. Any rust that is discovered should be removed via the use of non-fluffy cotton cloths. Furthermore, the mechanism, including the gear wheel, should be lubricated by high-grade grease.
*For an air blast circuit breaker, one of the first things to do is to check the air leakage, as well as when it is actually required. If a leakage is discovered, be sure to plug it. Additionally, all grading capacitors should be checked on a monthly basis for oil leakage and should be plugged if a leakage is discovered. Furthermore, measure the overall dew point of the operating air at the outlet of the air dryer on a yearly basis, which is something that can be done with the assistance of either a dew point meter or hygro meter.
*Austin Circuit Breaker Maintenance Tips. For a minimum oil circuit breaker, this is one that should be checked on a monthly bases for both oil level and oil leakage. If a leakage is discovered, it will need to be corrected in order to ensure that the level is at the desired amount. Additionally, a visual inspection of the breaker itself, as well as its operating mechanism, should be carried out on a quarterly basis, with proper action being taken if any damage is discovered. Furthermore, the oil dash pot, which can be found in the operating mechanism, will also need to be checked for oil leakage on a quarterly basis if a leakage is discovered. If the O-rings are found to be damaged or defective, simply replace them.
