Further, the fan hot hole is respectively arranged with cabinet upper and lower ends.
Further, towards outside cabinet, the air in cabinet is extracted out for the ventilation fan wind direction of top in the cabinet；The cabinet
Outdoor air is pumped into cabinet, two ventilation fans work at the same time so that cabinet by the ventilation fan wind direction of lower section towards in cabinet in vivo
Internal air circulation.
Further, the jacking mechanism includes cylindrical jack-up column, and the jack-up column is vertical with rotating arm, the top
It rises and shaft is connected between column and rotating arm.
The beneficial effects of the utility model：Utilize two ventilation fans so that the air circulation in high-tension switch cabinet body accelerates
Heat dissipation, while disposed at air vent is provided with filter cotton and filter screen, can purify into the air in cabinet, dust is avoided to enter.
1st, rotatable rotating arm is provided with, when rotating arm rotates, the jack-up column of pivot arm ends can drive bottom plate to cabinet
Internal wall movement so that the space of filter chamber reduces, so as to which moment compresses filter cotton, when filter cotton compresses, the sky in filter cotton
Gas overflows, and the dust in filter cotton is blown out；Simultaneously bottom plate move back and forth, can jitter filtering net, the ash on filter screen is trembled down
Come, and ash is blown to outside cabinet using the air in filter cotton.
2nd, column is jacked up to be movably connected on rotating arm by shaft, when jacking up column and contacts baseplate, reduce impact force and
The frictional force of the two reduces noise and extends the service life of cabinet.
