The invention discloses an over-voltage protection device of a wire and a protection method thereof. The over-voltage protection device comprises a protection box, a protective cover and a fastening block. A mounting box is arranged at the inner side of the protection box; an electrical appliance protector is installed at the inner side of the mounting box; a conductor is connected to the outer side of the electrical appliance protector; and a protection tube is installed at the outer side of the conductor. A sleeving ring is connected to a fixed cylinder and is arranged at the outer side of aclamping piece; the fastening block is arranged at the inner side of the fixed cylinder and is connected with the fixed cylinder by a connecting shaft mutually; and a torsion spring is fixed above the fastening block and is arranged between the fastening block and the fixed cylinder. A pull rod is installed above the fastening block and is connected with the fixed cylinder mutually. According tothe over-voltage protection device, because the fixed cylinder has a hollow cylindrical structure and the fixed cylinder, the clamping piece, and the fastening block are made of copper metal materials, the wire can be installed conveniently, the electrification fault of the circuit is avoided, and the power transmission stability is improved.
Description
technical field [0001] The invention relates to the technical field of electric equipment, in particular to an electric wire overvoltage protection device and a protection method. Background technique [0002] Overvoltage protection refers to a protection method that disconnects the power supply or reduces the voltage of the controlled equipment when the voltage of the protected line exceeds a predetermined maximum value. Usually, a professional voltage protection device is installed in the circuit to protect the circuit from overvoltage. . [0003] Existing overvoltage protection devices cannot fully protect the wire access points, which may easily lead to loose wires or accidental contact by unrelated personnel. In view of the above problems, an innovative design is carried out on the basis of the original overvoltage protection device. Contents of the invention [0004] The purpose of the present invention is to provide a wire overvoltage protection device and protect...
