To ensure smoother operation of circuit breakers, proper maintenance is essential. Regular maintenance can extend their lifespan many times over – a win-win situation! Continuous maintenance is necessary to maintain their optimal working condition. So, what are the key points of their maintenance? This is a question that users need to explore. Let's learn about it together.

In terms of maintenance, we should keep the air fresh. Humid air, or air that isn't clean, can have serious consequences. Humid air decomposes into a mixture of hydrogen and oxygen, which can cause thermal breakage at connection points, and in severe cases, even lead to an arc chamber explosion. It also reduces insulation strength, causing surface discharge that is extremely dangerous to touch; the consequences of electric shock are unimaginable. Therefore, caution is paramount. Furthermore, pipes can become clogged during painting, leading to circuit malfunctions or even complete blockages. These are all examples of problems caused by unclean air, varying in severity, so it's essential to maintain clean air regularly.

Rubber parts are an important component and should be replaced regularly. This is because these components have a complex structure and require high sealing performance. Timely replacement of rubber parts is essential to ensure their performance keeps up.

All components of an air circuit breaker require regular inspection to ensure they are in good working order. Don't overlook even a small component; it might determine the proper functioning of the entire system. For example, the arc-extinguishing chamber needs regular inspection of its springs and dynamic/static contact points. Because of constant friction, overtravel can occur, gradually reducing pressure. If the overtravel becomes too small, the spring can deform, requiring timely replacement. The non-linear resistor needs its cleanliness checked, the desiccant replaced, and the resistance of the non-linear element measured. The main valve's piston and valve body dimensions checked to ensure they are within specifications; any discrepancies need immediate correction. The drive cylinder also requires inspection; its buffer zone adjusted to ensure proper isolating switch operation, and its accuracy checked regularly. Again, maintenance and replacement are key to maintaining optimal performance.

For the daily maintenance of circuit breakers, simply following the points mentioned above will yield significant results. Ensuring a clean operating environment, timely replacement of rubber parts, and thorough inspection of small components are all crucial steps. Spending a little time will reduce problems for the device. Maintaining equipment requires starting with small things in daily life and should not be overlooked.
