Description
Technical field
The present invention relates to a kind of insulating optical fiber insulator.
Background technology
Insulating optical fiber insulator is applicable to electric system electronic current mutual inductor to current measurement under high pressure, UHV (ultra-high voltage), 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 outside 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 insulation then with optical fiber.
Following problem can appear in above-mentioned optical fiber composite insulator: thermal expansivity 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 insulating property poor, significantly reduce the serviceable 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, yield rate 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 yield rate 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 serviceable life, therefore also do not have at present practical ceramic external insulation optical fiber porcelain insulator the performance of optical fiber porcelain insulator.
Summary of the invention
The objective of the invention is to have in order to solve existing optical fiber insulator that insulating property are poor, optical loss is big, processed complex, yield rate is low and serviceable life is short problem, and then provides a kind of soft insulating optical fiber insulator.
Technical scheme of the present invention 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, described soft rubber injects the inner chamber of hollow insulator by the hole for injecting glue on the last metal end, the dropping point of described soft rubber is greater than 200 ℃, the cone penetration of soft rubber is greater than 440dmm in the time of 25 ℃, the cone penetration of soft rubber is greater than 230dmm in the time of-40 ℃, and viscosity is at 50s
