Description
Technical field
The utility model relates to a kind of pull bar, relates in particular to a kind of vacuum pressure impregnation epoxy glass fabric pipe insulation pull bar.
Background technology
Used insulating material major part is an epoxy resin in the at present domestic high-voltage switch electric appliance industry product.Just use insulated tension pole to be example with the high-voltage switch gear circuit breaker, extensively adopt now be intermediate insulation partly with epoxy resin rod two cast joint then because what adopt is that solid epoxy resin is excellent, weight is big, has just increased the operating work of circuit breaker between invisible.
In addition; Epoxy resin and epoxyn itself is nontoxic, but since in manufacture process in order to make its combination property reach good degree, must add solvent, modifier and other Toxic; Therefore many epoxy resin " poisonous "; And cause work flow complicated, on the high side, more increased cost pressure.Can say that from mechanical strength and arc resistance the too high mechanical strength of resin of epoxide number is bigger, but more crisp, anti-electric arc ability; Intensity is all good during the medium high and low temperature of epoxide number, anti-electric arc ability; Intensity difference during the low then high temperature of epoxide number, anti-electric arc ability.Obviously the use to it is restricted in the high field of electric pressure.In sum, epoxide resin material has price height, poor product quality, processing technology complicacy, low, the anti-electric arc ability of mechanical strength etc.
The utility model content
The utility model proposes a kind of novel vacuum pressure impregnation epoxy glass fabric pipe insulation pull bar, and this vacuum pressure impregnation epoxy glass fabric pipe insulation pull bar viscosity is low: the viscosity of dipping glue is low, fugitive constituent is few, the curing exotherm amount is little, shrinkage is little, thermal coefficient of expansion is little.
The utility model solves the problems of the technologies described above the technical scheme that adopted like following description:
A kind of vacuum pressure impregnation epoxy glass fabric pipe insulation pull bar; Comprise the pull bar body; It is characterized in that: described pull bar body is a vacuum pressure impregnation expoxy glass stringing; Vacuum pressure impregnation expoxy glass stringing is provided with venthole, and vacuum pressure impregnation expoxy glass stringing two ends are bonded with joint, and joint is provided with the pin-and-hole that is used to be in transmission connection.
Further, preferred construction is that said venthole is four, is looped around on the vacuum pressure impregnation expoxy glass stringing.
Further, preferred construction is that said joint is provided with the pivot pin pressing plate and uses screw.
Further, preferred construction is, said vacuum pressure impregnation epoxy glass fabric external diameter of pipe is 35mm, and wall thickness is 5mm.
The utility model the beneficial effect of having taked technique scheme such as below description:
The first, viscosity is low: the viscosity of dipping glue is low, and the bubble of system is discharged easily, to the good penetrability of glass cloth
The second, fugitive constituent is few: fugitive constituent is few, can not form little air gap to product, and the insulation property of product are improved greatly.
Three, the curing exotherm amount is little: low thermal discharge can not cause vacuum pressure impregnation epoxy glass fabric tube material local solidification, can not produce bubble, and goods are not easy to crack.
Four, shrinkage is little: shrinkage is little of to guarantee the dimensional accuracy of impregnation material, goods, makes the inner residual stress of goods little, not easy to crack.
Five, thermal coefficient of expansion is little.
In sum, vacuum pressure impregnation epoxy glass fabric tubular tie, material compactness is high; Its electric property, mechanical performance are splendid, and moderate cost adopts the insulated tension pole of tubular structure to reduce weight; Improved tensile strength; Reduced operating work simultaneously, therefore can be widely used in High-Voltage Electrical Appliances, to improve the insulation property and the reliability of High-Voltage Electrical Appliances.
