Abstract

A soft insulating optical fiber insulator relates to an insulating optical fiber insulator. The soft insulating optical fiber insulator of the invention settles the problems of inferior insulating property, large optical loss, complex processing, low finished product rate and short service lifetime existing in the prior optical fiber insulator. The upper end of the hollow insulator of the invention is fixedly connected with an upper metal end cap through the upper metal flange. The lower end of the hollow insulator is fixedly connected with the lower metal end cap through a lower metal flange. The upper metal end cap is provided with a plurality of through holes and one glue injection hole. The lower metal end cap is provided with a plurality of through holes. A plurality of optical fiber jumper wires run through the inner chamber of the hollow insulator. The interfaces between the plurality of optical fiber jumper wires and the upper metal end cap and the lower metal end cap are respectively provided with one layer of sealant. The soft glue is injected into the inner chamber of the hollow insulator through a glue injection opening on the upper metal end cap. The soft insulating optical fiber insulator of the invention has the advantages of increasing the insulating property and service lifetime of the optical fiber insulator, greatly reducing the optical loss, simplifying the processing technique and increasing the finished product rate of the product.

Description

technical field [0001] The invention relates to an insulating optical fiber insulator. Background technique [0002] Insulated fiber optic insulators are suitable for electronic current transformers that measure current in high-voltage and ultra-high voltages in power systems. They are used as high-voltage insulation and support for high-voltage components of electronic current transformers, and transmit optical signals from high-voltage terminals to low-voltage terminals. At present, optical fiber insulators are generally optical fiber composite insulators with silicone rubber outer insulation. Use a solid epoxy rod, slot the wall of the epoxy rod, bury the optical fiber, then use silicone rubber, epoxy resin or other similar organic materials to bond and seal, and then set the outer surface of the epoxy rod to meet the requirements of external insulation. Umbrella sheath; or a hollow composite insulator is used, the optical fiber is passed through the through hole of the ...
