Protection device for terminal strip in transformer substation

The invention provides a protection device for a terminal strip in a transformer substation, which comprises a base and an upper cover, the base is clamped and fixed on the terminal strip, the upper cover is fixed on the upper surface of the base, a first magnetic part is arranged in the base, a second magnetic part is arranged in the upper cover, and the first magnetic part and the second magnetic part are fixed on the base. The base and the upper cover are mutually fixed through the first magnetic part and the second magnetic part; the base is provided with a plurality of fixing grooves, and the fixing grooves are used for fixing cables on the terminal strip; and when the base and the upper cover are fixed on the terminal strip, the terminal strip is completely wrapped, and a cable on the terminal strip is led out. On the basis of being originally clamped on the terminal row through magnetic attraction and space, the cable insulation device is similar to a box shape and isolates a cable; the secondary termi
