Close space；Wherein, the foreboard is bolted respectively with left plate and right panel, and the back plate passes through respectively with left plate and right panel
Bolt connection；The left plate and right panel inner side are provided with heat abstractor, and the heat abstractor is shutter；The back plate
On offer at least two through holes, be provided with radiator fan in the through hole；The foreboard, back plate, left plate, right panel, substrate and
Cover plate inner side is coated with shielding material layer.
Shell is arranged to convenient maintenance in time of being broken down inside demountable structure, variable-frequency power sources by the present invention, together
When, there is provided radiator structure, it is possible to reduce because the not enough power supply stability in use for causing of radiating and security.
Shielding material layer can prevent variable-frequency power sources external electromagnetic field for the interference of variable-frequency power sources, it is ensured that variable-frequency power sources
Stable operation, increases stability.
As preferred technical scheme：The foreboard is bolted respectively with left plate and right panel.Easy disassembly and inspection
Repair.
As preferred technical scheme：The back plate is bolted respectively with left plate and right panel.Further facilitate and tear open
Dress and maintenance.
Compared with prior art, the advantage of the invention is that：Shell is arranged to demountable structure, frequency conversion by the present invention
Power source internal breaks down and conveniently overhaul in time, meanwhile, there is provided radiator structure, it is possible to reduce because the electricity that radiating deficiency is caused
Source stability in use and security；Using structure of the invention, the fault rate of variable-frequency power sources can reduce at least 50%, so that greatly
Width improves the performance of electrical equipment, increased stability.
