[0044] The implementation principle of the embodiment of a new type of fuse protection device inside a box-type substation in the present application is:
[0045] During the use of the fuse, the fuse may fall due to improper installation by the operator or the screw slipping, resulting in power outage or leakage, affecting the safe use of electricity in the factory.
