What are the key points of daily maintenance of circuit breakers

In order to make the operation of circuit breakers more comfortable, we should not ignore its maintenance. If you maintain it frequently, its life will be many times higher. Why not? In order to keep it in good working condition, maintenance and upkeep need to be continuously strengthened. So, what are the key points of its maintenance? This is a question that users need to discuss. Let's follow the editor to understand it.

In terms of maintenance, we should keep the air fresh. If it is humid air or not cleaned, the consequences will be very serious. The humid gas decomposes into hydrogen and oxygen mixed gas, which will cause fracture insulation between the contact points, and in severe cases, it will cause arc chamber explosion. It will reduce the insulation strength, and the surface will gradually produce discharge, so you can't touch it. In case of electric shock, the consequences can be imagined, so it is better to be careful. In addition, the pipeline will be blocked when painting, and the circuit will fail or even get stuck. All of these are caused by unclean air, and the severity varies, so the air should be kept clean from time to time.

Rubber accessories are one of the most important ones. Rubber accessories should be replaced regularly because the structure of this device is very complex and the sealing performance requirements are high. In order to ensure its performance, it is necessary to replace rubber parts in time.

The various components of the air switch need to be checked regularly to keep them in a good technical condition. Don't ignore a small device, which may determine the normal operation of the device. For example, the arc extinguishing chamber needs to check its springs and dynamic and static contact points regularly because it is constantly rubbing, so the output point is overtraveled and the pressure will slowly decrease. When it is small to a certain band, the spring will be deformed and it needs to be replaced in time. The nonlinear resistor needs to be checked for cleanliness, the desiccant inside needs to be replaced, and the nonlinear chip resistance needs to be measured. Check the size of the piston and valve body of the main valve 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. It is also through maintenance and replacement to maintain its performance better.

For the daily maintenance of the circuit breaker, we only need to do the above points, and I believe there will be considerable results. Ensuring that the air in the environment where it is used is fresh, replacing rubber accessories in a timely manner, inspecting small components, etc. are all very important links. As long as you spend a little time, it will help reduce the trouble of the device. Maintenance of devices needs to start with small things in life and cannot be ignored.
