Description
Technical field
The invention belongs to electric power Material Fields, and in particular to press insulated conductor in a kind of anti-lightning strike broken string.
Background technology
Extensively using what is determined the advantages of being mainly him in electric system, he can solve to set middle pressure insulated conductor very well
Line contradiction particularly Urban Landscape Greening and power circuit channel and power circuit safe operation this great problem.But he
Have to life weakness, in power circuit by atmospheric over-voltage（Lightning stroke）During electric discharge, he just breaks, and power train is seriously affected after broken string
Outside the stable operation of system, bigger problem is to influence the security of the lives and property of the surrounding masses, and this in turn limits his application prospects.He
Broken string mechanism it is as follows：In middle pressure insulated conductor circuit by atmospheric over-voltage, insulating first as insulation cannot be met the requirements
Most weak spot is discharged, and dot breakdown occurs in insulating layer during electric discharge, and due to breakdown point very little, electric arc is immovable, causes this point
Temperature is very high, and the high temperature of moment makes this metallic aluminium melt and break.It is by the way of at present：On middle pressure insulated conductor circuit
Zinc-Oxide Arrester, inter-spike intervals, lightning conducter or coupling ground wire are installed additional to prevent middle pressure insulated conductor from breaking in atmospheric over-voltage
Measure, these are all passive types, and effect is not satisfactory or accident that often break.
Invention content
The defects of in order to overcome the prior art, the purpose of the present invention is to provide a kind of rational in infrastructure, favorable working performance
Insulated conductor is pressed in anti-lightning strike broken string.
The present invention technical solution be：
Insulated conductor is pressed in a kind of anti-lightning strike broken string, it is characterized in that：Including the steel core that steel wire strand is combined into, steel core outer cladding aluminium
Conductor layer, aluminum conductor layer surface coating aluminium chloride or ammonium chloride, it is exhausted that aluminium conductor is coated with conductor shield, EP rubbers successively outside
Edge layer, insulation screen, every three aluminium conductors form one group, insulation screen be externally provided with low-smoke non-halogen flame-retardant band around
Covering, low-smoke non-halogen flame-retardant band lapping layer are externally provided with separation layer, polyvinyl chloride insulation layer are coated with jointly outside the separation layer,
The polyvinyl chloride insulation layer is coated with sheath；The sheath is prepared according to following technique：
By 100-200 parts of acrylic resins, 30-50 parts of epoxy resin, 20-30 parts of boron nitride, 10-15 parts of natural rubbers, 1-2 parts
Fire retardant, 1-2 part photomask agent and 1-2 parts of stabilizer mixing, form mixture；The mixture is put into sheathing machine
It is melted（Melting temperature is 160 DEG C, time 15min）, injection molding later to get.
The cross-sectional area of steel core is 16 ~ 25 square millimeters；The cross-sectional area of aluminum conductor is 50 ~ 300 square millimeters.
Rational in infrastructure, favorable working performance of the invention；It is applied on middle pressure insulated conductor conductor wire face（Heat）Easy sublimator material.Middle pressure
It is easy due to being applied on conductor wire face during insulated conductor disruptive discharge（Heat）Sublimator material in the case of a high temperature, distils straight by solid
It connects when becoming gas, takes away a large amount of heat, reduce the temperature of point of discharge.Add 16 to 25 square millimeters among middle pressure insulated conductor
Multiply steel core.The fusing point of steel is 1300 to 1400 degrees Celsius, and aluminium only has 660.2 degrees Celsius, and the only half of steel, in this way
Both aluminium conductor was made to fuse when high temperature occurs in point of discharge, steel core is not blown, and insulated conductor is made not break, actually
Improve middle pressure insulated conductor intensity under high temperature.The present invention has additional multilayer insulation shielded layer in the structure of internal layer, fills out simultaneously
Filled with heat safe magnesia powder, flame-resistant insulation performance is more preferable, and the scope of application is big.
