[0001] The utility model relates to the technical field of low-voltage switch cabinets, in particular to a circuit protection cover of a low-voltage switch cabinet. Background Art

[0002] As an important equipment for power distribution, low-voltage switchgear plays an important role in modern power distribution networks and engineering construction. As the terminal equipment of the power transmission and distribution system, low-voltage switchgear can be installed outdoors, in parks and other places. Part of the wires at the bottom of the low-voltage switchgear are exposed to the outside of the cabinet, and it is inevitable that they will be bitten by small animals in the wild, causing damage to the wires.

[0003] The circuit protection cover of the existing low-voltage switch cabinet usually inserts the wires from one end of the protection cover, so it can only be installed before the wires are arranged, and it is impossible to protect the low-voltage wire part where the wires have been arranged at the bottom; the circuit protection cover of the existing low-voltage switch cabinet is of fixed length, and the length of the protection cover cannot be adjusted according to the length of the wire, and it needs to be cut. For wires that are too long, it is necessary to replace the protection cover, which is more troublesome. Therefore, a circuit protection cover for a low-voltage switch cabinet is proposed to solve the above problems. Utility Model Content
