Abstract
The utility model relates to a non-filled hollow composite optical fiber pillar, which belongs to the composite optical fiber pillar of the high-voltage optical fiber transformer. The composite optical fiber pillar comprises an upper metal part (1), a silicone rubber umbrella skirt (2), an epoxy fiberglass tube (3), a silicone rubber inner creepage-increasing sheath (4), an optical fiber (5) and a lower metal accessory (6). The two ends of the inner creepage-increasing sheath (4) are respectively provided with a linkage interface (7) and a linkage interface (8), the bottom of the sheath is provided with a creepage-increasing tube (9), the creepage-increasing tube (9) can increase the minimum air discharge distance and the creepage distance along the surface of the optical fiber and the inner wall of the tube. When the heads of multiple inner creepage-increasing sheaths (4) are connected, the vertically straight-through insulating tube can be divided into multiple separate chambers, thereby forming a winding air discharge distance and a winding creepage distance in the insulating tube (see Figure B on Page 2/2), preventing the creeping discharge and flashover during condensation, and greatly improving the internal insulating strength of the product. The utility model has the advantages of no need for penetration or embedment of optical fibers, no need for filling, no leakage, no pollution, convenient production, high internal insulating strength, no need for product maintenance and the like.
Description
Technical field
The utility model relates to a kind of composite fiber pillar of high voltage optical fiber mutual inductor.
Background technology
The electrical network intellectuality is the developing direction and the world trends of power grid construction, and replaces the inevitable choice that traditional mutual inductor is intelligent electrical network with the optical fiber mutual inductor.The existing composite fiber pillar (claiming the composite fiber insulator again) that is used for the optical fiber mutual inductor has two kinds: first kind is to slot to wear to bury optical fiber on the solid insulator plug; Second kind is to fill insulating gas, liquid or solid material penetrate optical fiber in hollow insulator core pipe after.The equal defectiveness of said two products: in solid bar, wear to bury and fill solid insulating material after wearing optical fiber in optical fiber or the hollow tubular, all can not guarantee the bonding quality between optical fiber and packing material and the plug, influence the interior insulating property of product.And then there are problems such as sealing, leakage and pollution in blanketing gas or liquid etc. in hollow tubular, must periodical inspection, detection and maintenance, increased the maintenance workload of run unit.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aim to provide a kind of exempt to wear bury, exempt to fill, non-maintaining Hollow Compound optical fiber pillar.
Exempt to fill the composite fiber pillar and climb sheath (4), optical fiber (5) and following metal-ware (6) formation by increasing in last metal (1), silicon rubber full skirt (2), epoxy fiberglass tubes (3), the silicon rubber.In increase and climb sheath (4) two ends and be provided with and be connected interface (7), (8), be provided with to increase in the sheath bottom and climb pipe (9), increase and climb pipe (9) and can increase minimum atmospherical discharges distance, also can increase along the creepage distance of optical fiber surface and inside pipe wall.Increase in several climb sheath (4) first place and be connected after, straight-through up and down insulation tube is separated into several independently spaces, make atmospherical discharges distance and creepage distance tortuous circuitous (seeing the 2/2nd page of B of accompanying drawing) in the insulation tube, creeping discharge and flashover when having avoided condensation have improved the interior dielectric strength of product greatly.
The utlity model has optical fiber exempts to wear and buries, exempts to fill, do not have advantages such as leakage, pollution-free, convenient for production, interior dielectric strength height, product be non-maintaining.
The utility model also can be used as the compound inslation pillar and uses.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 increases the synoptic diagram of climbing after sheath connects in being.Fig. 3 increases the sectional view of climbing sheath (4) in being, Fig. 4 increases in being and climbs the sheath vertical view.
Embodiment:
Climb sheath (4) with reference to Fig. 3 and Fig. 4 with increasing in the Mold Making silicon rubber.Increase in reference to Fig. 2 optical fiber being penetrated one by one climb sheath (4) after, two end interfaces (7), (8) join end to end, the length that bonding one-tenth is identical with product;
With reference to Fig. 1, insert in the epoxy fiberglass tubes (3) after sheath (4) outside surface is smeared viscose glue increasing in from beginning to end bonding to climb, and, charge into gases at high pressure sealed at both ends, make the outer wall of sheath (4) be close to the inwall of epoxy fiberglass tubes (3), keep air pressure until viscose glue is laid down air pressure after solidifying;
Increase the epoxy fiberglass tubes (3) of climbing sheath (4) in will having and place sulphurated siliastic full skirt (2) in the mould of producing the compound inslation pillar;
Load onto two ends metal-ware (1), (5).
By above-mentioned steps, can produce as shown in Figure 1 exempt to fill Hollow Compound optical fiber pillar.
Claims (4)
1. exempt to fill Hollow Compound optical fiber pillar, it is characterized in that metal-ware (1) below is provided with to increase in silicon rubber full skirt (2), epoxy fiberglass tubes (3), the silicon rubber successively to climb sheath (4), optical fiber (5) and following metal-ware (6).
2. according to claim 1ly exempt to fill Hollow Compound optical fiber pillar, increase the two ends of climbing sheath (4) in it is characterized in that and be provided with and be connected interface (7), (8), the sheath bottom is provided with to increase climbs pipe (9).
3. want 1 or 2 describedly to exempt to fill Hollow Compound optical fiber pillar according to right, increase in it is characterized in that and climb sheath (4) and make with elastomeric material.
4. want 1 or 2 describedly to exempt to fill Hollow Compound optical fiber pillar according to right, increase in it is characterized in that to climb sheath (4) made of plastic.
