Background technology
Insulating optical fiber insulator is applicable to electric power system electronic current mutual inductor to current measurement under high pressure, superhigh pressure, as the High-Voltage Insulation and the support of electronic current mutual inductor high voltage component, and light signal is reached low-pressure end from high-pressure side.At present, optical fiber insulator generally is the optical fiber composite insulator of silicon rubber external insulation.Employing solid epoxy rod at epoxy rods wall fluting, is buried optical fiber underground, uses silicon rubber, epoxy resin or other similar organic material adhering and sealing then, satisfies the silicon rubber umbrella cover that external insulation requires the outer surface setting of epoxy rods then; Perhaps adopt hollow combined insulator, in the through hole of hollow combined insulator, whole or part is filled up this through hole with organic insulating material then with optical fiber.
Following problem can appear in above-mentioned optical fiber composite insulator: thermal coefficient of expansion difference between organic material, optical fiber and epoxy plug or the epoxy cylinder three, and when expanded by heating, organic material can increase optical loss to the optical fiber build-up of pressure; Catching a cold when shrinking, can produce the slit between each material, enter moisture and foreign material after, flashover so that final the puncture can appear, cause insulation property poor, significantly reduce the useful life of optical fiber composite insulator, and organic material is when solidifying, need main equipment to carry out heat treated, processed complex, easy damaged optical fiber fractures optical fiber, be difficult to produce qualified optical fiber composite insulator, rate of finished products is very low.
Known ceramic external insulation optical fiber porcelain insulator adopt glass end envelope, glazing or roasting sealing, but ordinary optic fibre is difficult to bear above-mentioned sealing means, makes rate of finished products very low.Because other material coefficient of thermal expansion difference of coefficients is very big relatively for porcelain, if the sealing means that adopts is improper, easily cause trickle slit alternately the time in that heat is cold, can and cause direct infringement useful life, therefore also do not have at present practical ceramic external insulation optical fiber porcelain insulator the performance of optical fiber porcelain insulator.
The utility model content
The purpose of this utility model be have in order to solve existing optical fiber insulator that insulation property are poor, optical loss is big, processed complex, rate of finished products is low and useful life is short problem, and then provides a kind of soft insulating optical fiber insulator.
The technical solution of the utility model is: soft insulating optical fiber insulator is by the multifiber wire jumper, last metal end, following metal end, last metal flange, following metal flange, hollow insulator, soft rubber and two-layer fluid sealant are formed, the upper end of described hollow insulator is affixed by last metal flange and last metal end, the lower end of described hollow insulator is by metal flange is affixed with following metal end down, have a plurality of on the described upward metal end by hole and a hole for injecting glue, have a plurality of holes of passing through on the metal end under described, and a plurality of on the last metal end offer by the hole is corresponding by a plurality of on hole and the following metal end, described multifiber wire jumper is through the inner chamber of hollow insulator, and the two ends of every optical patchcord pass respectively on the metal end pass through the hole and with last metal end on pass through the hole of passing through on the corresponding down metal end in hole, the intersection of described multifiber wire jumper and last metal end and following metal end respectively is provided with one deck fluid sealant, and described soft rubber injects the inner chamber of hollow insulator by the hole for injecting glue on the last metal end.
The utility model compared with prior art has following beneficial effect: the employing of soft rubber, because soft rubber has the flow behavior of liquid, when expanding with heat and contract with cold, guaranteed can not produce the slit between soft rubber, optical patchcord and the hollow insulator three, improved the insulation property and the useful life of optical fiber insulator; Soft rubber solidifies under normal temperature condition, has avoided the influence of heating process to the leaded light coefficient of optical fiber, has reduced optical loss greatly, has simplified processing technology, has improved the rate of finished products of product.
