By installing the circuit breaker mechanism sealing device, the protection level of the circuit breaker mechanism reaches IP65, which can avoid the influence of condensation and dust on the circuit breaker mechanism and reduce the probability of failure.

[0004] When existing diesel generator sets are used outdoors, the inlet and outlet cables of the circuit breaker cabinet are generally not sealed, causing rainwater and dust to enter the generator set through the output cables of the circuit breaker cabinet, posing certain safety hazards; and existing diesel generator sets are also easily damaged by rain when used outdoors, especially at the vents of the diesel generator sets. Rainwater can easily enter the interior through the vents, causing short circuit damage to internal parts of the diesel generator set. At the same time, the heat dissipation effect of the vents is not ideal, and it is difficult for devices in some dead corners to effectively ventilate and exchange heat, thereby reducing the service life of the diesel generator set.
