Abstract
The utility model discloses a fuse for protection of a photovoltaic system, which can meet the demand for protection of circuits of the photovoltaic system. In order to solve the above problems, the fuse comprises a fusion body, the fusion body comprises a fusion tube, a fusion mass, an inner cover, an outer cover and an arc extinguishing medium, the fusion mass is arranged in the inner cavity of the fusion tube and the arc extinguishing medium is filled into the inner cavity, and the inner cover and the outer cover sequentially cover the two ends of the inner cavity of the fusion tube. The fuse is characterized in that: sealing gaskets are arranged on the fusion tube. The sealing gaskets are arranged on the two ends of the fusion tube to play the sealing and buffering role, and two caps on the two ends of the fusion tube are prevented from being arced through, and the reliability of the products is greatly improved.
Description
Technical field
The utility model relates to a kind of low-voltage electrical apparatus, especially a kind of fuse.
Background technology
Existing technology fuse-link only can be applied to exchange below the 690V; and the fuse of solar energy photovoltaic system protection usefulness needs direct current 1000V; prior art products can not satisfy the requirement of the route protection of DC1000V; if adopt prior art to be used for the protection of solar energy system; can cause the end cap of fuse-link to puncture; base bursts, the potential safety hazard that protected object damages.
The utility model content
The technical problems to be solved in the utility model provides a kind of fuse that can satisfy the demand of photovoltaic system route protection.
For addressing the above problem, the technical solution adopted in the utility model comprises fuse-link, described fuse-link comprises fusion tube, melt, inner cap, enclosing cover, arc-extinguishing medium, described fusion tube inner chamber arranges melt and fills up arc-extinguishing medium, its two ends are capping inner cap and enclosing cover successively, it is characterized in that: described fusion tube arranges sealing gasket.
Fuse is used in described photovoltaic system protection, and it is characterized in that: described sealing gasket is made by silicon rubber, liquid glue curing agent.
Fuse is used in described photovoltaic system protection, and it is characterized in that: described sealing gasket, its thickness are 1 mm-3mm.
Fuse is used in described photovoltaic system protection, and it is characterized in that: described sealing gasket is arranged between inner cap front end or inner cap and the enclosing cover.
Fuse is used in described photovoltaic system protection, it is characterized in that: described melt has 5-7 row's circular hole or semicircle orifice, and bore dia is 1.0 mm-2.0mm, and melt thickness is 0.05mm-0.25mm.
The fuse that the utility model is realized arranges sealing gasket at the fusion tube two ends, plays the effect of sealing and buffering, has guaranteed that two disconnected caps not by arc through, have improved the reliability of product greatly.Designed 5 at melt and drained into 7 rows' hole, and limited relevant parameter, played the product reliable breaking, further improved the global reliability of product.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is explosive view of the present utility model.
Embodiment
As shown in Figure 1, fuse is used in photovoltaic system protection of the present utility model, comprises fuse-link; described fuse-link comprises the pipe fusion tube 4 of being made by high strength glass fiber; at fusion tube 4 inner chambers melt 5 is installed, and is filled up quartz sand, at the two ends of fusion tube 4 sealing gasket 3, inner cap 2 and enclosing cover 1 are installed successively.Described sealing gasket 3 also can be installed between inner cap 2 and the enclosing cover 1, also can play same order ground.
Sealing gasket 3 of the present utility model is made by silicon rubber, liquid glue or curing agent, and its thickness is 1 mm-3mm, and shape and fusion tube 4 inner chambers or outer neck adapt, and is as the criterion to reach sealing.To play best sealing and the effect of buffering, guaranteed that two disconnected caps are not by arc through.
Further optimize this programme, described melt 5 arranges 5-7 row's circular hole or semicircle orifice, and bore dia is 1.0 mm-2.0mm, and melt thickness is 0.05mm-0.25mm.
The above only is preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all is included within the protection range of the present utility model.
