Abstract
The utility model provides a mercury fuse. The essential technical proposal is that the mercury is filled in an annular passage of the inner cavity of glass tubes and in the entire annular passage, a one-way valve is on one end, a piston is on the other end clipping a section of thin passage. The mercury in the thin passage generates heat and expands then opens the one-way valve, the mercury runs back to the annular passage and the mercury in the thin passage disconnectes achieving the insurance act. While in use continuly, the piston is withdrawn and the mercury in the thin passage namely is filled to continue to use. The service life of the utility model is long. The utility model is suitable to use in various electrical equipment.
Description
The utility model belongs to a kind of safeties that are applied on the electric equipment, particularly a kind of fuse that is applied on the electric equipment.
The fuse of electric equipment application at present is a galvanized wire, is disposable.Electric equipment needs a lot of fuses every year like this, and particularly consumption is just bigger when maintenance of equipment.So frequent replacing was both uneconomical, and was also inconvenient.Particularly some family does not have backup fuse at ordinary times, in case fuse has been broken, just replaces with copper wire, and fuse capacity is not reached, and can bring danger to electric equipment, does not have safety effect.
The purpose of this utility model is to provide a kind of mercury fuse that can avoid plumbous matter fuse deficiency.
The purpose of this utility model is achieved in that it is improved on the basis of simple glass pipe fuse, in the circular passage in the glass tube inner chamber, fill with mercury, in the full annular passage, one end one-way cock, other end piston, press from both sides out one section passage aisle, we are referred to as the fuse passage.Wherein piston is made with conductor, and the other end of piston is screwed on polar cap, and another polar cap contacts with the fuse passage.The utility model is with filling with mercury in the fuse passage as fuse.
Operation principle: the utility model is added in the circuit, and the mercury of electric current in polar cap, piston, fuse passage flows to another polar cap.When the electric current of mercury was excessive in flowing through the fuse passage, the mercury heating was expanded, and backs down one-way cock, and a part of mercury flows back to the circular passage, and promptly the mercury in the fuse passage disconnects.When desire continues to use, extract piston out, the mercury in the circular passage flows into the fuse passage, and it is full of, and heads into piston again, installs, and becomes a new fuse again.
The utility model is compared with plumbous matter fuse, and is reusable, improves useful life greatly, brings convenience for vast family.
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model longitudinal sectional view.
3 li of circular passages in glass tube 5 inner chambers, fill with mercury, in the full annular passage, one section passage aisle---fuse passage 7 is arranged, its outlet has an one-way cock 8 to seal, this valve is to use rubber system, is pressed in the exit of fuse passage at ordinary times by elasticity, and the exit also contacts with negative cover 9.The porch of fuse passage has piston 4 to seal.For improving sealing, at piston head, the sealing ring 6 that also has a circle to make with rubber, the other end of piston is fixed on the positive cover 1 with screw 2.When big electric current flow through, the mercury heating in the fuse passage was expanded, and backs down one-way cock, and mercury flows back in the circular passage, and the mercury fusing in the fuse passage reaches safety effect.
Claims (3)
1, a kind of mercury fuse, form by glass tube and two polar caps being positioned at the glass tube two ends, it is characterized in that: in the circular passage in the glass tube inner chamber, fill with mercury, in the full annular passage, an end one-way cock, other end piston, press from both sides out one section fuse passage, piston is made with conductor, and the other end of piston is screwed on polar cap, and another polar cap contacts with the fuze passage.
2, mercury fuse according to claim 1 is characterized in that: at piston head, and the sealing ring that has a circle to make with rubber.
3, mercury fuse according to claim 1, it is characterized in that: one-way cock is made with rubber.
