4. The box-type transformer with internal dehumidification function as claimed in claim 1, wherein: a first spring (13-3) is fixed at the bottom of the insulating rubber rod (13-2), and the bottom of the first spring (13-3) is fixed on the jack (13-1); the first spring (13-3) plays a role in supporting and damping.
5. The box-type transformer with internal dehumidification function as claimed in claim 1, wherein: the outer end of the second air inlet pipe (12-2) is connected with a third air inlet pipe (12-3) in a penetrating way, and the inlet of the third air inlet pipe (12-3) is arranged downwards; a third air inlet pipe (12-3) arranged downwards prevents rainwater from entering the slope top (6) in rainy days.
6. The box-type transformer with internal dehumidification function as claimed in claim 5, wherein: a dust screen (12-4) is fixed at the inlet of the third air inlet pipe (12-3); the dust screen (12-4) prevents dust from entering the slope roof (6).
7. The operation principle of the box type transformer with the internal dehumidification function as claimed in claim 1, wherein: when the novel electric dust collector is used, the fan (12-13) is started, external air flow enters the filter box (12-7) from the second air inlet pipe (12-2) and the first air inlet pipe (12-1), moisture in the external air is adsorbed when passing through the desiccant particles (12-10) in the net box (12-9), dry air flow is blown out of the transformer body (7) in the inner box (10) through the fan (12-13), the air flow is discharged out of the inner box (10) through the second air outlet hole (12-15) and is discharged through the first air outlet hole (12-14), and cooling, dehumidification and dust removal can be synchronously realized; after the dehumidifier is used for a certain time, screwing down a second fixing bolt (12-6) to enable the triangular cover (12-5) to be taken down, opening a second door body (12-8), and taking out the net box (12-9) to replace the dehumidifying agent particles (12-10) in the net box; when the transformer body (7) runs, the second spring (13-4) between the support plate (1) and the support leg (3) plays a role in shock absorption, and the insulating rubber rod (13-2) is movably inserted into the insertion hole (13-1) and cannot generate displacement during shock absorption.
