Detailed description of the invention
For this utility model is better described, hereby with a preferred embodiment, and coordinate accompanying drawing that this utility model is elaborated, specific as follows:
The thermocouple that this utility model provides is with flexible intrinsic safety compensating cable, including several pair twist groups.Wherein, the present embodiment only illustrates the construction of cable of the present utility model including a pair twist group.As it is shown in figure 1, pair twist group includes positive pole conductor 1 and cathode conductor 2, positive pole conductor 1 is wrapped with positive pole insulating barrier 3, and cathode conductor 2 is enclosed with negative insulation layer 4.Positive pole conductor 1 and cathode conductor 2 are stranded, and also include shunt line 7, positive pole conductor 1 in the present embodiment, cathode conductor 2 and shunt line 7 are wrapped in a semi-conductive layer 5, it is filled with packed layer 6 in space in semi-conductive layer 5 and between positive pole conductor 1, cathode conductor 2 and shunt line 7, wherein, it is additionally provided with outer jacket 8 outside semi-conductive layer 5.
Preferably, the shunt line 7 in the present embodiment is that silver-plated copper free wire is constituted, and its concrete structure is 18 filament diameters is that the silver-plated oxygen-free copper tow strand of 0.12mm forms.Positive pole conductor 1 in the present embodiment is nickel chromium triangle thermocouple wire, and cathode conductor 2 is Nickel-Silicom thermocouple silk.And the monofilament external diameter of nickel chromium triangle thermocouple wire and Nickel-Silicom thermocouple silk is 0.12mm, the dimensions of the cable conductor of this material exceedes standard GB/T/T2614, and in national standard, material specification is minimum for 0.2mm.Additionally, the positive pole conductor of this cable and cathode conductor stranded for cable core time stranding lay is conductor assembly outer diameter 10～12 times.
Preferably, outer jacket is the anti-explosion set that inside is provided with fiberglass flame silk, makes cable have good shielding properties and fire resistance.Wherein, the material of semi-conductive layer is the mixture of conductive black and silane cross-linked polyolefin, by conductive black is become semi-conductive layer with silane cross-linked polyolefin is mixing, constitutes screen layer of good performance.
In other preferred embodiments of the present utility model, it is possible to arranging this compensating cable is have 2 and above pair twist group, now, the outside of multiple pair twist groups, it is provided with above-mentioned outer jacket, protects the pair twist group within cable by outer jacket.
As in figure 2 it is shown, the manufacture method of the flexible intrinsic safety compensating cable of above-mentioned thermocouple, comprise the following steps:
S1: by stranded for the positive pole conductor and cathode conductor that wrap up insulating barrier respectively for cable core, becomes strand with the lay of stranding lay be conductor assembly outer diameter 10～12 times；
Wherein, this step is additionally included in positive pole conductor and cathode conductor is wrapped up before insulating barrier respectively, positive pole conductor and cathode conductor is filled with argon and stewes burning.Wherein, adopt argon to fill and stew the stranded rear conductor of burning, it is possible to the minima of the percentage elongation of material is brought up to 30% by GB 25%, reaches the standard of six class conductors so that this cable possesses the requirement of fexible conductor.
S2: positive pole conductor and cathode conductor are stranded for wrapped semi-conductive layer after one shunt line additional after cable core；
