Utility model content
Goal of the invention: in order to overcome the shortcoming of prior art; the utility model provides a kind of new forms of energy fuse-link being exclusively used in wind energy, the protection of photovoltaic group string; be applicable to the operational environment of various complexity of wind energy, photovoltaic fuse; rated current is brought up to 20A from maximum 15A, transship and short circuit time can quick disjunction, safe and reliable.
Technical scheme: in order to solve above technical problem, the utility model provides a kind of new forms of energy fuse-link, comprises high-strength ceramic fusion tube and is located at the high breaking silver body and high-silicon quartzite sand in high-strength ceramic fusion tube; Described high breaking silver body is located at center in described high-strength ceramic fusion tube, and described high-silicon quartzite sand is for filling up the remaining space of high-strength ceramic fusion tube inside; Described high breaking silver body subsection setup, two ends are that the segment body between link, link is provided with metallurgical effect point and is all enveloped by arc silica gel point.Preferably, described high breaking silver body divides 8 sections of settings, and two ends are link, and middle 6 sections are provided with metallurgical effect point and are enveloped by arc silica gel point.
Junction between described high breaking silver body section and section be a pair back to semicircle.
Described high-strength ceramic fusion tube two ends high-precision pressure machine press-in contact cap, on inside the cap body that the two ends spot welding machine being positioned at the high breaking silver body of high-strength ceramic fusion tube is connected to two contact caps, with high-precision pressure machine press-in silicagel pad and end cap outside contact cap.High-strength ceramic fusion tube two ends high-precision pressure machine press-in contact cap, ensures that the contact cap of melt electrical connection and high-strength ceramic fusion tube are installed firmly.The two ends spot welding machine of high breaking silver body is connected on two contact caps, for reliable disjunction provides connecting path.Preferably, the length of high-strength ceramic fusion tube is identical with high breaking silver body, ensures contact cap and high breaking silver body stable connection.
Beneficial effect is: compared with prior art, and the utility model tool has the following advantages:
1. high breaking silver body of the present utility model design have employed the design of erose variable cross-section, this design is less than the Melt temperature rise of existing design, low in energy consumption, capacity is larger, breaking capacity is higher, relative to existing product maximum rated current 15A, maximum breaking capacity 10KA, the utility model maximum rated current is 20A, maximum breaking capacity is 30KA, be suitable for wind energy, the operational environment of the various complexity of photovoltaic fuse.
2. the existing mechanism of structural rate of the present utility model is simpler, assembles more convenient, the working efficiency greatly improved; Existing product selects the fuse-link of 20A larger than this product design size simultaneously, and the minimum overall dimension of the product of the design, less cost, just can meet the selection of 20A rated current.
3. the utility model is novel in design, use variable cross-section fracture, port increases quenching moment, use in new material arc extinguishing pad, fuse-link and fill arc quenching material, when there is overload and short circuit current in the line, the rapid extinguish arcs of this fusing physical efficiency, the electric current in line disconnection.

Embodiment
embodiment 1below in conjunction with drawings and Examples, set forth the utility model further.
New forms of energy fuse-link as shown in Figure 1 to Figure 3, comprises high-strength ceramic fusion tube 1, contact cap 2, silicagel pad 3, end cap 4, high breaking silver body 5, metallurgical effect point 6, arc silica gel point 7 and high-silicon quartzite sand 8.High breaking silver body 5 is located at center in high-strength ceramic fusion tube 1, and in high-strength ceramic fusion tube 1, remaining space fills up high-silicon quartzite sand 8; High-strength ceramic fusion tube 1 two ends high-precision pressure machine press-in contact cap 2, ensures that the contact cap 2 of melt electrical connection is installed firmly with high-strength ceramic fusion tube 1; The two ends spot welding machine being positioned at the high breaking silver body 5 of high-strength ceramic fusion tube 1 is connected on inside two contact cap 2 cap bodies, with high-precision pressure machine press-in silicagel pad 3 and end cap 4 outside contact cap 2; High breaking silver body 5 subsection setup, two ends are that the segment body between link, link is provided with metallurgical effect point 6 and coated arc silica gel point 7, the junction between section and section be a pair back to semicircle.
The course of work: to fill up in high-strength ceramic fusion tube 1, jolt ramming high-silicon quartzite sand 8; Outside high-precision pressure machine press-in end cap 4 and the silicagel pad 3 of contact cap 2; New forms of energy fuse-link and fuse disconnecting switch with the use of, fuse-link is inserted in isolating switch, rotates 60 degree and connect contact position to conduction, make whole protection system line conduction; Fuse disconnecting switch two binding post place connects the wire in protected object, forms the circuit of object of protection and the electrical connection of protection system.Connect the power supply of whole system, new forms of energy fuse-link is also started working simultaneously, and when operating current is in normal scope, fuse-link normally works, and can accept little overcurrent in short-term, and fuse-link can not fuse; When occurring overload and short circuit current in circuit, and when exceeding the current range and official hour that fuse-link specifies, metallurgical effect point 6 in fuse-link in high breaking silver body 5 starts heating under the effect of electric current, and the alloy in metallurgical effect point 6 starts to produce metallurgical effect with high breaking silver body 5.
Before overload current is not eliminated, the temperature of metallurgical effect point 6 progressively raises, high breaking silver body 5 in design barbed portion under the effect of high temperature from solid state into liquid state, the temperature of metallurgical effect point 6 raises further simultaneously, the silver of high breaking silver body 5 barbed portion is vaporized from liquid state, in high-strength ceramic fusion tube 1, form gases at high pressure, produce electric arc simultaneously.
Because the design of the high sublevel silver body 5 of this product is the scheme aiming at new forms of energy product design, end cap 4 devises silicagel pad 3, high breaking silver body 5 devises arc silica gel point 7, when there is overload and short circuit current in the online design road at this few place, the rapid extinguish arcs of this fusing physical efficiency, the electric current in line disconnection.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
