Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of circuit breaker protection, and in particular relates to an intelligent pole-mounted circuit breaker protection structure with primary and secondary deep integration. Background Art
[0002] Outdoor vacuum circuit breakers have overload, short circuit and undervoltage protection functions, and have the ability to protect lines and power supplies. They are mainly used in medium-voltage overhead line power grids to separate and connect load currents, overload currents and short-circuit currents. The vacuum circuit breaker pole is an integral component formed by embedding the vacuum interrupter and the conductive parts related to the circuit breaker into easily solidified solid insulating materials such as epoxy resin or thermoplastic materials, which can reduce the size of the circuit breaker and is conducive to the miniaturization of the switch.
[0003] The existing patent with authorization announcement number CN216084747U discloses a primary and secondary fusion column-mounted intelligent circuit breaker protection structure. By providing a shell, the circuit breaker is waterproofed. At the same time, the internal heat can be dissipated through the heat conductive sheet and air conduction holes to protect its use.
[0004] However, the shell will greatly affect the heat dissipation of the circuit breaker. The heat dissipation effect is poor only through the heat conductive sheet and the air conduction holes, which can easily affect the service life of the circuit breaker. Utility Model Content

[0012] Preferably, a second dustproof net is provided in the second air duct on a side away from the protective shell.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. During operation, the heat inside the protective shell is conducted through multiple heat conducting sheets, and then transferred to the outside of the protective shell to contact with the outside air for heat dissipation.
[0015] 2. The two first cooling fans blow air into the protective shell to form an airflow inside the protective shell, so that the airflow takes away the heat inside the protective shell.
