Description
Technical field
The present invention relates to electrical equipment, more particularly to a kind of heat-resisting measuring body lightning protection control cable.
Background technology
Electrical equipment includes primary equipment and secondary device, the secondary device that cable belongs in electrical equipment.With China
Economical continues to develop, and the application of cable is more and more wider, its performance requirement also more and more higher.Traditional cable heat resistance
Difference, when being struck by lightning, the cable core in it is easily blown, and has a strong impact on the popularization of cable with using.
The content of the invention
The technical problem existed based on background technology, the present invention proposes a kind of heat-resisting measuring body lightning protection control cable, with
Solve above-mentioned technical problem.
The heat-resisting measuring body lightning protection control cable of one kind proposed by the present invention, including：Cable core, screen layer, ground plane, thermal insulation layer
And oversheath；Cable core includes many cores, core body and lapping layer, and many cores are annularly distributed around the cable core center, core
Including the conductor positioned at middle part, the insulating barrier and refractory layer that are coated on successively outside conductor, core body is located at two lines of arbitrary neighborhood
Between core, and offset therewith, it uses elastic heat-absorbing material to be made, and coordinating with core makes the cable core have circular cross-section,
Lapping layer is wrapped in the core and core body periphery using heat-barrier material, and screen layer is coated on outside the cable core, ground plane bag
Overlay on outside screen layer, thermal insulation layer is coated on outside ground plane, oversheath is coated on outside thermal insulation layer.Refractory layer using steel wire and
Copper wire mixed weaving is formed.Screen layer is formed using zinc-plated proof copper-wire braided.Ground plane is formed using many stranded copper wires are wrapped,
Thermal insulation layer is formed using glass fiber tape is wrapped, and oversheath is made of elastic flame material, and oversheath is provided with multiple radiatings
Hole.
The heat-resisting measuring body lightning protection control cable of one kind proposed by the present invention, when being struck by lightning, ground plane short-time thermal amount
It is small, the probability that cable core is blown by thunderbolt is reduced, and play the function of partly shielding effect electromagnetic wave；It is heat-insulated in the case of thunderbolt
Most of heat can be isolated in outside cable core by layer, and the core inside cable core remains to normal work；Core body energy between core
The heat of cable core is enough absorbed into, core temperature is not risen too high, it is ensured that the performance of core, by external force
When, core body also can offset part stress by the elastic performance of itself, make core that short disconnected core will not occur because tearing；Refractory layer
While core heat resistance is lifted, also core is isolated, even if insulation melting layer, the conductor of adjacent lines in-core will not also be sent out
Raw contact, it is ensured that the stabilization of power transmission.Heat-resisting measuring body lightning protection control cable proposed by the present invention, heat resistance is good, electricity
Power transmission is stable, still can normal work in the case of thunderbolt.
Brief description of the drawings
Fig. 1 controls the structural representation of cable for a kind of heat-resisting measuring body lightning protection proposed by the present invention.
Embodiment
As shown in figure 1, Fig. 1 controls the structural representation of cable for a kind of heat-resisting measuring body lightning protection proposed by the present invention.
Reference picture 1, the heat-resisting measuring body lightning protection control cable of one kind proposed by the present invention, including：Cable core, screen layer 4, ground connection
Layer 5, thermal insulation layer 6 and oversheath 7；Cable core includes many cores 1, core body 2 and lapping layer 3, and many cores 1 are around the cable core center
Distribution annular in shape, core 1 includes the conductor 11 for being located at middle part, the insulating barrier 12 and refractory layer that are coated on successively outside conductor 11
13, core body 2 is located between two cores 1 of arbitrary neighborhood, and offsets therewith, and it uses elastic heat-absorbing material to be made, and with core 1
Cooperation makes the cable core have circular cross-section, and lapping layer 3 is wrapped in the core 1 and the periphery of core body 2, shielding using heat-barrier material
Layer 4 is coated on outside the cable core, and ground plane 5 is coated on outside screen layer 7, and thermal insulation layer 6 is coated on outside ground plane 5, outer shield
Set 7 is coated on outside thermal insulation layer 6.
Cable in the present embodiment is when being struck by lightning, and the short-time thermal amount of ground plane 5 is small, reduces cable core and is burnt because being struck by lightning
Disconnected probability, and play the function of partly shielding effect electromagnetic wave；In the case of thunderbolt, thermal insulation layer 6 can isolate most of heat
Outside cable core, the core 1 inside cable core remains to normal work；Core body 2 between core 1 can be absorbed into the heat of cable core
Amount, makes the temperature of core 1 not rise too high, it is ensured that the performance of core 1, when by external force, and core body 2 also can be by certainly
The elastic performance of body offsets part stress, makes core 1 that disconnected core will not occur because tearing；Refractory layer 13 is heat-resisting in lifting core 1
While performance, also core 1 is isolated, even if insulating barrier 12 melts, the conductor 11 in adjacent core 1 will not also come in contact,
It ensure that the stabilization of power transmission.
Refractory layer 13 is formed using steel wire and copper wire mixed weaving, also acts resistance to compression, function of shielding.Screen layer 4 is used
Zinc-plated proof copper-wire braided is formed, and screen layer 4 is not oxidizable, and possesses certain mechanical performance.Ground plane 5 in such scheme is used
