Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a waterproof device for circuit breakers. Background Technology

[0002] A circuit breaker is a power protection device whose main function is to control and protect power systems. Under normal circuit conditions, a circuit breaker can carry and interrupt current; under abnormal circuit conditions, such as short circuits or overloads, the circuit breaker can disconnect the circuit within a specified time, thereby protecting other equipment and lines in the power system from damage. Circuit breakers are widely used in various power systems, including power plants, substations, industrial production lines, residential and commercial buildings, etc.

[0003] Traditional circuit breaker devices lack a dedicated waterproof structure and have poor moisture resistance. In humid or water-immersed environments, moisture can easily seep into the circuit breaker, increasing the risk of electric shock. Furthermore, moisture entering the circuit breaker can cause short circuits, potentially leading to serious consequences such as fires. Moisture also corrodes the metal components inside the circuit breaker, causing rust and oxidation on the surface of the components, thus accelerating equipment aging and reducing the performance and lifespan of the circuit breaker. Utility Model Content
