Description
Technical field
The utility model relates to a kind of surface-adhered type fuse, and particularly a kind of breaking capacity reaches the surface-adhered type ac high-voltage fuse that 250VAC/100A requires.
Background technology
Relative same specification thick film screen printing formula fuse structure, with the tube fuse of unsettled fuse-wires structure, often there is the remarkable advantages such as low, the anti-pulse ability of internal resistance is strong, yet when it is subject to high-voltage large current impact, the electric arc of melt open circuit association can produce very large pressure and heat, when serious, can cause shell to break and even explode, even be also difficult to make the product of this class formation to be applied to high voltage field more than 250VAC by fill the arc quenching materials such as quartz sand in shell.
The bad problems of disjunction such as fuse shell breaks in order to solve, blast, conventionally way is in shell, to fill the arc quenching materials such as quartz sand, when fuse failure, in the fossula of quartz sand, produces electric arc, it is subject to the cooling of quartz sand and adsorption effect, and electric arc is extinguished rapidly.But when the disjunction of surface-adhered type fuse requires to reach 250VAC/50A when above, the arc extinguishing effect of quartz sand also becomes not obvious, traces it to its cause, one side may be due to quartz sand arc extinction performance not good due to; The effect that may be also on the other hand the blast pressure of generation while bearing incessantly melt fusing due to shell is broken or is exploded.CN102122595A discloses a kind of arc quenching agent for fuse, this arc quenching agent adds chlorate in traditional quartz sand arc quenching material, as sodium chloride, potassium chloride, calcium chloride, barium chloride etc., utilize quartz sand can draw the heat that electric arc produces moment, the chloride ion that pyrolysis goes out can in and the ion that produces of electric arc, avoid ion that electric arc produces under hot conditions by arcing, thereby play good arc quenching effect.But owing to there being the requirement of Halogen in surface mount miniature fuse, and halogen has stronger moisture pick-up properties, larger to the reliability effect in the long-term use procedure of metal bath, thereby this improved range of application has very big restriction.In CN202977346U, announced a kind of high pressure resistant surface-adhered type tube fuse, by filling gel layer around the melt in insulated tube, utilize high-insulativity and the high withstand voltage breakdown capability of silica gel to carry out extinguish arcs, utilize the elasticity of silica gel itself to absorb the energy producing in melt fusing process, yet during practical operation, this structure has just lost the effect of expection when the specified breaking capacity when fuse requires to surpass 250VAC/50A.
Summary of the invention
The shell that the blast pressure that melt produces during disjunction under high-voltage large current impacts and arcing pressure easily cause surface-adhered type fuse breaks or explodes, and makes it can not safe disjunction under the condition of 250VAC/100A.Possible cause for bad generation, the utility model on the one hand by forming a pressure release narrow slit structure on ceramic cartridge, thereby can adopt the mode of vacuumizing that the arc extinguishing slurry of liquid form is filled into shell inside, reduce task difficulty, after solidifying, filling effect is better; The blast pressure producing in the time of can also being used for by the pressure release of this narrow slit structure on the other hand reducing melt fusing, thus make surface-adhered type miniature fuse can meet the safe disjunction requirement of 250VAC/100A and above condition.
A kind of surface-adhered type ac high-voltage of the utility model fuse, comprise insulation crust, fuse is through the center of insulation crust, and fix and form and be electrically connected to insulation crust two side ends cap by scolder, between fuse and insulation crust, be arc quenching material layer, insulation crust is provided with at least one pressure release slit.The material of described insulation crust is ceramic material, preferably with toughness reinforcing alumina-based ceramic materials of mode such as glass fibre or zirconia doping, to meet the requirement of its mechanical strength; Described pressure release slit is when insulation crust moulding, and through adopting the micro chink of the perforation one side pipe wall thickness that the mould of particular design forms, its length is 1mm ~ 3mm, and width is 0.05mm ~ 1.5mm; The metal wire material that described fuse adopts the electric conducting materials such as copper, copper alloy, nickel to make, diameter and the length of silk material, select according to the dimensions of fuse and practical application; The existence form of described fuse in insulation shell can for raw silk rings, curly wire or by fuse around an insulation support body, as the winding structure on glass wire; Described scolder is that solder containing pb or high temperature lead-free solder all can; Described arc quenching material be can be at more than 300 ℃ temperature the ablator of long-time stable existence, preferably adopt high-temperature silica gel or high temperature silicone resin material as arc extinguishing slurry; Described end cap is preferably made with surface gold-plating or silver-plated copper sheet metal.
Owing to taking above technical scheme, the utlity model has following advantage:
The quartz sand arc quenching material that tradition is used when being subject to blast pressure and impacting, the interaction that produces power between quartz sand particle, and with the extruding of shell generation sharp impacts, can affect to a certain extent the mechanical strength of shell; And the utility model by forming the structure of a slit on insulation shell, realized the more closely knit filling of arc extinguishing slurry, and the high-temperature silica gel arc quenching material adopting is by solidifying to form a block packed layer with certain toughness, compression area is large, and when being subject to blast pressure impact, can also there is deformation by part and absorb certain pressure, and by self fusing absorption melt heat around, accelerate melt cooling, thereby there is the effect of arc extinguishing.The blast pressure that the existence of pressure release narrow slit structure produces in the time of can also reducing melt fusing, the impact of the impact easing off the pressure on shell, thus reduced the possibility that shell bursts; In addition, the utility model structure and technique are simple, and production efficiency is high, and applicable industrialization is produced continuously.
