The inspection and replacement of breaker parts is the basis to ensure the smooth progress of the work, and to some extent it helps to effectively extend the service life of the breaker. Let’s introduce the inspection and replacement of through-body bolts: 　　
Before loosening the through-body bolts, the gas pressure in the upper body should be released. Otherwise, when the through-body bolt is removed, the upper body will eject and cause serious consequences. 　　
Before loosening the through-body bolts, the nitrogen in the upper body should be released. After removing all the through-body bolts, check them for cracks and damage at the same time. 　　
When we are using the breaker, we should try our best to avoid problems. In short, we must not only do a good job of inspection before work, but also perform correct operations and do sufficient daily maintenance work!
