Abstract
The utility model relates to a cross linking electric cable accessory for the connection of cable with electric instrument like overhead line, transformer and switch. The utility model totally changes the traditional outdoor termination structure, using composite bushing of frp liner pipe outward extrusion silicon rubber parachute skirt to replace the porcelain bushing, using an insulating binder to replace the insulating filling liquid, through which the utility model is simple structured and is convenient to install, besides, the utility model improves pollution resistance of the outdoor terminals with a more reliable insulating and sealing performance, and avoids leakage and influent; the utility model can also prevent explosion and fire in case of breakdown, the utility model is fixed in any angle.
Description
The utility model relates to a kind of cross-linked power cable annex, connects use as cable with electric equipments such as overhead wire, transformer, switches.
The crosslinked cable outdoor terminal generally is made up of parts such as external insulation insulator, insulation filling liquid, interior insulation stress awl, upper-lower seal gold utensil, some fastening bolts in the world at present, as the product of Sweden KOBDON company, Japan general outdoor terminal structure and the U.S. G﹠amp of each company; The outdoor terminal of W company, the design feature of above-mentioned three kinds of products is: external insulation adopts insulator, and anti-pollution improves the flashover performance, and interior insulation improves Electric Field Distribution with stress cone, improves electric property with the filling dielectric.But also have very important disadvantages simultaneously: the whole terminal parts are many, the installation trouble, and the workmen is required height.Seepage easily takes place in dielectric, and moisture enters electrical breakdown easily takes place after the terminal, in case puncture, insulator will explode, and the fragment of insulator will injure pedestrian and other electric equipments, the dielectric easy breaking out of fire of burning.
At problem set forth above, the utility model provides a kind of crosslinked cable compound external insulation outdoor terminal, and its purpose is to solve the problem that crosslinked cable outdoor terminal parts are many, aspects existence such as bothering, pedestrian and other electric equipments are easily blasted, injured to the insulator structure is installed.
The utility model comes to be realized by the following technical programs:
The compound external insulation outdoor terminal of a kind of crosslinked cable, insulation was rubber stress cone, insulation filling liquid, upper-lower seal gold utensil and cable in it included, and it is characterized in that: use the composite bushing of extrusion modling silicon rubber full skirt formation outside the fiberglass bushing pipe as external insulation in the most external of terminal.
Replace insulation filling liquid by a kind of compressible elastic insulated glue, be filled in the inside of fiberglass bushing pipe.
Advantage of the present utility model and effect:
The utility model has changed the project organization of traditional outdoor terminal fully, the composite bushing that pushes the silicon rubber full skirt with the fiberglass bushing pipe outward replaces insulator, replace insulation filling liquid with a kind of elastic insulated glue, so not only simple in structure, easy for installation, and having improved the resistance to soiling of outdoor terminal, insulation property and sealing property are more reliable, ne-leakage, water inlet, in case can avoid after puncturing exploding and the generation of fire incident.
Accompanying drawing 1 is a structural representation of the present utility model.
The utility model is specifically described by execution mode below in conjunction with accompanying drawing:
Being described in detail as follows of primary structure part of the present utility model:
1 is external insulation structure:
External insulation improves the electric property of outdoor terminal and anti-fouling performance and needn't use insulator again with the composite bushing of the outer extrusion modling silicon rubber full skirt of fiberglass bushing pipe, and its performance is good, in light weight.
2 is interior insulation:
The rubber stress cone uniform electric field that ripe use experience is arranged is adopted in interior insulation, the stay pipe sealing of stress cone lower end and tie cable.
3 is elastic insulated glue:
In the fiberglass bushing pipe, fill elastic insulated glue, improve the electric property of terminal.Elastic insulated glue is a kind of compressible colloid, has good electric property and sealing property.Can guarantee the reliability of product long-time running.
4,5 is the upper-lower seal gold utensil:
Directly be bonded in the two ends of fiberglass bushing pipe 1 by last lower flange, top, lower seal gold utensil are fixed with bolt and flange, compress O-ring seal, sealing and attached cable terminal.
6 is cable:
The whole terminal structure is sleeved on the cable 6, upper-lower seal gold utensil and cable 6 sealing and fixing.
Press outdoor terminal dependable performance that the utility model makes, simple in structure, easy for installation, can arbitrarily angledly install.
Claims (2)
