[0014] Furthermore, a drawer is provided at the bottom of the cabinet, a ventilation hole is provided above the drawer, and a desiccant is placed in the drawer.

[0015] Furthermore, a suspended dry powder fire extinguisher is hung on the top of the inner side of the cabinet.

[0016] Furthermore, a self-locking universal wheel is provided at the bottom of the base.

[0017] The beneficial effects of the present invention are:

[0018] An inverter medium frequency power supply cabinet of the present invention can effectively dissipate heat inside the inverter medium frequency power supply cabinet through a heat dissipation mechanism, and has a good dust prevention effect. Through the provided shock-absorbing component, the inverter medium frequency power supply cabinet is shock-absorbed when it moves or is impacted, thereby preventing electrical components in the inverter medium frequency power supply cabinet from being damaged.
