Abstract
A safe photo-recombination cable capable of preventing and extinguishing fire comprises a central optical unit, wherein the optical unit consists of optical fibers and fiber paste filled among the optical fibers; the outer side of the optical unit is wrapped by an aluminum alloy wire layer, a hard aluminum wire layer, a buffering layer and a sheath in a concentric way, wherein the buffering layer is filled with dried powder for extinguishing fire; the dried powder for extinguishing fire is prepared through the mixing of the following raw materials in parts by weight: 80-100 parts of 200-meshes glass fragment, 10-20 parts of an additive and 30-60 parts of coal ash. The safe photo-recombination cable has the advantages of simple structure, wide application range and great fire-proof effect. Meanwhile, as the optical fibers and a power transmission cable are combined into a whole, secondary wiring is avoided, investment can be greatly reduced, and the cost is lowered.
Description
Technical field
The invention belongs to power communication system technical field, particularly relate to a kind of electric wire had compared with high safety factor.
Background technology
China's communication of power system realizes optical fiber communication mainly through fiber plant composite overhead ground wire and All Dielectric self-support at present on main line, at circuit itself without ground wire, and cannot fiber plant composite overhead ground wire; Ground safe distance is not enough, cannot solve scissors crossing, tower bar strength margin is not enough, limit in the All Dielectric self-support construction of line and excessively can realize optical fiber communication by fiber plant composite aerial phase line, adopt optoelectronic composite cable significantly can reduce investment, cost-saving, the comprehensive operation efficiency of network can be improved.
The patent that optoelectronic composite cable is relevant is also too numerous to enumerate, and great majority all concentrate on the combination aspect of light unit and cable, often have ignored most important fail safe.This cable of a large amount of laying only relies on the passive protection of insulating barrier to be far from being enough in the wild, along with the increase of China's power consumption, country improve constantly for the attention degree of electric power safety, studying novel can the photoreactivation cable of Initiative Defense fire be a kind of trend.
Summary of the invention
Technical problem to be solved by this invention is for the deficiency in background technology, provide a kind of can the safety optical composite cable of fireproof fire-extinguishing.
In order to solve above technical problem by the following technical solutions: a kind of can the safety optical composite cable of fireproof fire-extinguishing, comprise the light unit at center, light unit is made up of optical fiber and the fine cream of filling between the fibers; The outer concentric of light unit is coated with aluminium alloy wire layer, hard-drawn aluminium wire layer, resilient coating and sheath; Wherein, fire extinguishing dry mash is filled with in resilient coating; Described fire extinguishing dry mash is mixed by the raw material of following weight portion: 200 object cullet 80 ~ 100 parts, auxiliary agent 10 ~ 20 parts, 30 ~ 60 parts, pulverized coal ash.
Wherein, at least containing three optical fiber in the light unit at center, in the light unit between three optical fiber, fine cream is full of.
Preferably, sheath is made up of cross-linking polyethylene materials.
Described auxiliary agent is grouped into by the one-tenth of following weight portion: 2 ~ 4 parts, calcium carbonate, 1 ~ 3 part, sodium nitrate, cellulose 4 ~ 6 parts, gelling agent 1 ~ 3 part.
Concrete, described fire extinguishing dry mash comprises 200 object cullet 80 parts, auxiliary agent 10 parts, 40 parts, pulverized coal ash; Wherein, 10 parts of auxiliary agents are made up of 3 parts, calcium carbonate, 2 parts, sodium nitrate, cellulose 3 parts, gelling agent 2 parts.
Structure of the present invention is simple, applied widely, flameproof effect is good.Meanwhile, light harvesting fibre and electrical power distribution cable, avoid secondary wiring, significantly can reduce investment, cost-saving.Adopt cullet, pulverized coal ash etc. as the raw material of fire extinguishing dry mash, selection is extensive, cost is low; Fire extinguishing dry mash is running into the too high situation of photoreactivation cable internal temperature, can a large amount of heat of active absorption, the formation of preliminary defence fire.For the naked light in the external world; fire extinguishing dry mash can well protect photoreactivation cable itself before overcoat melts, and can absorb a large amount of heat, when overcoat loses protective effect; the heat absorption of fire extinguishing dry powder becomes floccule, intercepts the contact of naked light and photoreactivation cable.
Wherein, gel have single-phase decentralized system and two-phase decentralized system point, the gel belonging to two-phase decentralized system is that Small molecular inorganic drug colloidal particles are present in liquid with network structure, has thixotropy, also claims suspendible gel, preferred gel aluminum hydroxide.
All raw material itself is nontoxic, "dead", can not discharge harmful substance, can not contaminated foundation and underground water, has good environment protecting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
