A circuit breaker is an indispensable circuit safety device in daily life, but how can we ensure that the circuit breaker will always operate as smoothly as new after using it for a long time? If we want to keep the circuit breaker as new all the time, then we need to work hard on its maintenance in our daily life. Because a circuit breaker that is regularly maintained, its service life alone will be longer than that of a circuit breaker that is not maintained at ordinary times. So, what are the main points of the maintenance of circuit breakers? Let's find out together.
In fact, there are many things to pay attention to in the maintenance of circuit breakers. One of them is to keep the air dry. If the air is too humid, the gas in the air will be decomposed into a mixture of hydrogen and oxygen, which will cause heat preservation after fractures between the contact points, and in severe cases, the arc chamber will explode, thus causing The consequences are very serious, so it is better for us to be cautious in this regard.
In the maintenance of circuit breakers, a very important accessory is rubber accessories. Because the structure of this device is very complex, the requirements for sealing performance are very high, so it is necessary to replace the rubber parts in time and regularly.
The various parts of the air switch need to be checked regularly to keep them in a good technical condition. Don't ignore a small device, maybe it determines the normal operation of the device. For example, the arc extinguishing chamber needs to regularly check its springs, dynamic and static contact points, because it is constantly rubbing, so the pressure will gradually decrease when the point is over-travel. When it is small to a certain belt, the spring will deform. , to be replaced in time. The varistor needs to be checked for cleanliness, the desiccant inside is replaced, and the varistor must be measured. The main valve checks the size of the piston and the valve body to see if its size is within the specified range. If it does not meet the requirements, it needs to be corrected in time. The drive cylinder also needs to be checked, adjust its buffer, ensure its isolation switch, and check its accuracy in time, and also maintain its performance better through maintenance and replacement.
The above are some maintenance tips about circuit breakers in daily life. Remember the following key points: application environment for certification, timely replacement of rubber parts, inspection of small parts, etc. We only need to do the above points, which will be very effective for the maintenance of circuit breakers in daily life of. Every link is a very important link. As long as you regularly spend a little time to maintain the circuit breaker, you can ensure the safety of our electricity use.
