What are the main points of daily maintenance of miniature circuit breakers?Posted by elcb on February 16th, 2020 In order to make the operation of the miniature circuit breaker more comfortable, we must not neglect its maintenance. If you regularly maintain it, its life will be many times higher. Why not? For its good working condition, maintenance and maintenance need to be continuously strengthened. What are the main points of its maintenance? This is a problem that users need to discuss. Let’s follow Xiaobian together.
In the maintenance of miniature circuit breaker, we should keep the air fresh. If it is humid air or it is not clean, the consequences of it are very serious. The decomposition of the wet gas into hydrogen and oxygen gas mixture will cause thermal insulation after the fracture between the contact points. In severe cases, the arc chamber will explode. It will let the insulation strength become lower, the surface will gradually produce a discharge, so that you can not touch, in case of electric shock, the consequences can be imagined, so be cautious as well. Also, when the pipe is blocked during the paint, the circuit will fail or even get stuck. These are all caused by the unclean air, and they are very different. Therefore, we should always keep the air clean.
Rubber accessories are one of the most important ones. Miniature circuit breaker should be replaced with rubber parts regularly because the structure of this device is very complicated and the sealing performance is high. In order to ensure its performance, it is very timely to replace the rubber parts. necessary.
The various parts of the air switch need to be checked regularly, so that they are in a good state of technology, do not ignore a small device, perhaps it will determine the normal operation of the device. For example, an arc extinguishing chamber needs to periodically check its springs, static and dynamic contact points, because it constantly generates friction. Therefore, if there is over-travel, the pressure will gradually decrease. When the arc is small, the spring will deform. , to be replaced in time. The non-linear resistance needs to check its cleanliness, replace the desiccant inside, and measure the non-linear sheet resistance. The main valve checks the size of the piston and the valve body and see if its size is within the specified range. If it does not meet the needs of timely correction. The drive cylinder is also inspected, its buffer zone is adjusted, its isolation switch is ensured, and its accuracy is checked in time. It is also through the maintenance and replacement to maintain its performance better.
For the daily maintenance of miniature circuit breaker, we only need to do the above points, I believe there will be no small effect. It is important to ensure that the air in the environment it uses is clean, timely replacement of rubber parts, inspection of small parts, etc. It only takes a little time for you to help the device to reduce the hassle. Maintenance equipment needs to be lived Starting from the small things, we can’t ignore it.
