Description
Technical Field
The utility model discloses a fuse for power equipment especially indicates an explosion-proof fuse, has excellent isolated electric arc and explosion-proof efficiency.
Background
Fuses are widely used in electronic and electrical products to protect the products from excessive current. The principle that the fuse can protect a product is that when current flows through a conductive fuse with proper impedance, the fuse is blown due to overheating when the current exceeds rated current, and then the current is isolated from entering the product. The higher the impedance after the burn-off, the better the isolation effect. Generally, the larger the cross-sectional area of the fuse, the lower the resistance and the higher the rated current. The fuse is connected with the protected circuit in series, and when the fuse is used in a rated current range, the voltage drop and the temperature rise are smaller and better. The fuse wire is heated by excessive current, an electric arc is generated before the fuse wire is completely fused, the electric arc is instantaneous and local high energy, the destructive power is strong, and the electric arc is an important factor which must be considered in the design and the manufacture of the fuse wire.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned shortcomings, the present invention provides an explosion-proof fuse, which includes: the alloy wire is arranged in the first pipe body in a penetrating mode, the length of the alloy wire is larger than that of the first pipe body, and two ends of the alloy wire extend to the outer side of the first pipe body; at least one second pipe body, which is combined outside the first pipe body in a wrapping way, and the length of the second pipe body is greater than that of the first pipe body; a plurality of insulating fixing pieces which are filled in the second pipe body and are bonded on the end faces of the two ends of the first pipe body, and the insulating fixing pieces are coated on the outer side of the alloy wire; and a plurality of cover bodies which are combined at two ends of the second tube body, and the inner sides of the cover bodies are combined with two ends of the alloy wires.
Furthermore, the two ends of the alloy wire and the covers are respectively jointed by soldering tin.
Furthermore, the first tube body is made of quartz glass, and the second tube body is made of ceramic.
Further, the thickness of the second tube is larger than that of the first tube.
Furthermore, the insulating fixing part is silica gel.
Through the technical scheme, the utility model discloses an explosion-proof fuse has excellent isolated electric arc and explosion-proof efficiency.
