Abstract
The utility model relates to an outdoor high pressure current limiting fuse. The utility model essentially consists of a stick shape mainstay insulating body, a tightening flange and a fuse. The stick shape mainstay insulating body comprises an epoxy insulating stick and an outside die pressing silica gel umbrella sweep; the fuse comprises a connecting bolt, a connecting cap, a flange tray, a spring, a fuse tube, an insulating tube and an umbrella sweep which are assembled with the pressing method; the outside of the insulating pipe is pressed with a pair of silica sweep; the middle of the bolt and the tightening flange are fixed on the stick shape insulating body to form the T-shaped high pressure current limiting fuse. As the umbrella adopts the one-time forming art, the utility model is only 15kg; and the utility model enhances the water repelling capability, the creepage ratio moment and enhances the insulating capability.
Description
The utility model relates to the outdoor high-voltage fuse that uses in the electric power system.
Post insulator, lightning arrester, push-and-pull lock switch and outdoor high-voltage fuse often will be housed in electric power system at present.Above-mentioned outdoor high-voltage fuse mainly is made up of solid core post insulator, lock ring flange and fuse.Wherein, clavate pillar insulator it be to constitute by outer one group of porcelain full skirt of the suit group of epoxy insulation rod; Fuse comprises wiring end cap, melt pipe, insulated tube, full skirt group, with the method that press-fits melt pipe and wiring end cap are placed in the insulated tube, the outside puts the full skirt group, the full skirt group is formed by stacking by a plurality of porcelain full skirts, the porcelain full skirt is fixed on the solid core post insulator with the lock ring flange at the middle part then, forms ' T ' shape structure.Because usefulness is that the porcelain full skirt is assembled into heavy full skirt group, makes fuse weight reach 80 kilograms, the hydrophobicity of porcelain full skirt group is low, creepage littler than square, and insulating properties is low, and corona phenomenon takes place sometimes.
The purpose of this utility model provide a kind of in light weight, hydrophobicity is high, creepage bigger than square, the outdoor high-voltage current limiting fuse of good insulating.
The purpose of utility model is to realize like this, be to utilize existing outdoor high-voltage current limiting fuse, use the porcelain full skirt group that external insulation uses instead the silicon rubber one-shot forming technique, the main element that makes whole composition electrical equipment all by integral sealing in the silicon rubber full skirt, change the shape of full skirt simultaneously.
This outdoor high-voltage current limiting fuse mainly is made up of solid core post insulator, lock ring flange and fuse.Wherein, clavate pillar insulator it be to constitute by epoxy insulation rod outside mold pressing silica gel full skirt group; Fuse comprises connection bolt, wiring end cap, ring flange, spring, melt pipe, insulated tube and full skirt, with the method that press-fits spring and melt pipe are placed in the insulated tube, ring flange and wiring end cap are buckled in two ends, wiring nut is positioned on the wiring end cap again, one group of silica gel full skirt of insulated tube outside mold pressing, the silica gel full skirt is fixed on the solid core post insulator with the lock ring flange at the middle part then, constitutes the high-voltage and current-limitation fuse of ' T ' shape structure.
Full skirt diameter in this high-voltage and current-limitation fuse is identical, also can vary in size, and the full skirt that varies in size uses at interval.
This outdoor high-voltage current limiting fuse because the full skirt group has adopted the silicon rubber one-shot forming technique, alleviates overall weight, and weight has only 15 kilograms, has improved hydrophobicity, creepage than square increase, good insulation preformance simultaneously.
The present invention is further described below in conjunction with embodiment and accompanying drawing.
One of Fig. 1, outdoor high-voltage current limiting fuse embodiment structural representation.
Two structural representations of Fig. 2, outdoor high-voltage current limiting fuse embodiment.
Three structural representations of Fig. 3, outdoor high-voltage current limiting fuse embodiment.
Four structural representations of Fig. 4, outdoor high-voltage current limiting fuse embodiment.
Referring to Fig. 1, Fig. 2, the utility model is a kind of outdoor high-voltage current limiting fuse, mainly is made up of solid core post insulator 1, lock ring flange 2 and fuse 3.Wherein, fuse 3 comprises connection bolt 4, wiring end cap 5, ring flange 6, spring 7, melt pipe 8, insulated tube 9 and full skirt 10, with the method that press-fits spring 7 and melt pipe 8 are placed in the insulated tube 9, ring flange 6 and wiring end cap 5 are buckled in two ends, again connection bolt 4 is positioned on the wiring end cap 5, it is characterized in that one group of silica gel full skirt 10 of insulated tube 9 outside mold pressings; It is to be made of one group of silica gel full skirt 10 of epoxy insulation rod outside mold pressing for a clavate pillar insulator, silica gel full skirt 10 is fixed on the solid core post insulator 1 with bolt 11 and lock ring flange 2 at fuse 3 middle parts, constitutes the high-voltage and current-limitation fuse of ' T ' shape structure.
Referring to Fig. 1 full skirt outline drawing, full skirt periphery section is the wedge angle taper.
Referring to Fig. 2 full skirt outline drawing, full skirt periphery section is the isosceles dihedral.
Referring to Fig. 1～Fig. 4, among the embodiment, the full skirt diameter is identical, also can vary in size, and the full skirt that varies in size uses at interval.
This outdoor high-voltage current limiting fuse moulding process is simple, and overall weight is light, hydrophobicity raising, creepage bigger than square, good insulation preformance.
