Management device based on substation desktop operation and maintenance

The utility model discloses a management device based on substation desktop operation and maintenance, which comprises a shell and a mainboard, the mainboard is arranged at the bottom of the inner wall of the shell, and the two sides of the top and the bottom of the shell are fixedly connected with protective blocks. When the shell falls off, deformation occurs after the protective blocks make contact with the ground to relieve falling impact force, then the falling impact force is absorbed through the buffer grooves and the supporting columns and transferred to the two sides, then the mainboard is fixed through the fixing screws and the base, and the mainboard and the shell are prevented from falling off when falling off; and then vibration of the mainboard is reduced through the buffer pad, the mainboard is prevented from being damaged, the problems that an existing management device is poor in protection performance in use, the mainboard in the management device is damaged when the management device is imp
