Abstract
A compensation cable for a temperature-resistant thermocouple is characterized in that an alloy wire conductor includes a single alloy wire or a plurality of twisted alloy wires; a fusible polytetrafluoroethylene resin PFA insulation layer is extruded on the alloy wire conductor to form an insulation core; a positive insulation core is twisted with a negative insulation core to form a twisted pair; a PFA unit sheath is extruded on the twisted pair to form a twisted pair unit; a plurality of twisted pair units are arranged in sequence to form the cable core; a polytetrafluoroethylene tape is wound on the outer surface of the cable core to form a wrap layer; an integral tin-plated copper shield layer is braided on the wrap layer and an integral shield lead-in wire; and fusible polytetrafluoroethylene resin PFA material is extruded outer surface of the integral shield layer to form an outer sheath layer. The compensation cable suits thermocouples of type S, type R, type N, type K, type E,type J and type T used in match with compensation cables, and has the advantages of high flame resistance, high and low temperature resistance, electromagnetic interference resistance, simple manufacture, and so on.
Description
Technical field
The utility model relates to compensating cable for thermocouple, relates in particular to a kind of heat-resistance type thermocouple compensating cable, belongs to technical field of electric wires and cables.
Background technology
Compensating cable for thermocouple, it is the identical a pair of lead that has insulating barrier of nominal value that in comprising the certain temperature range of normal temperature, has with the thermo-electromotive force of the thermocouple that is mated, connect thermocouple and measurement mechanism such as galvanometer etc. with them, to compensate the error that variations in temperature was produced of they and thermocouple junction.Compensating wire is divided into two kinds of extended pattern and offset-types.
Under the special occasions, compensating cable uses in higher temperature (200 ℃ and more than) environment usually for a long time.And under high ambient temperature, compensating cable must adopt high temperature resistant type insulating material and sheath material.The high temperature resistant type material is also more at present, exotic material polyimides PI described in Chinese patent application CN200510095376.6 or polyether-ketone PEK or polyether-ether-ketone PEEK or polysulfones PES.The high temperature resistant grade of this type of material is all about 250 ℃, but material price is very high, and also very high by its compensating cable valency that produces, market demand is very little.And the fluorinated plastics also have heat-resisting quantity, price is relatively low, can be easier to the fluorinated plastics exhaustive fluorinated ethylene propylene FEP460 commonly used and the meltable polyflon PFA of melt-processed, Comparatively speaking, the former temperature resistant grade is the highest at 200 ℃, main shortcoming is that environmental stress resistance is relatively poor, and cracking has certain limitation easily.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of heat-resistance type compensating cable for thermocouple is provided, making it have high flame retardant, anti-high/low temperature, anti-electromagnetic interference, make advantages such as simple.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model heat-resistance type compensating cable for thermocouple is:
The design feature of the utility model heat-resistance type compensating cable for thermocouple is that alloy silk conductor adopts single or many alloy silk conductor lay configuration, on alloy silk conductor, extrude and form meltable polyflon PFA insulating barrier formation insulated wire cores, with one just, one negative two thoroughly does away with the edge core is twisted into the pair twist group, on described pair twist group, extrude PFA unit sheath and constitute unit pair twist group, described unit pair twist group is arranged stranding in order and is constituted cable core, form belting layer at the wrapped poly-Teflon tap of the outer surface of described cable core, the total screen of braiding tinned copper wire on belting layer and total shielding drainage thread extrudes meltable polyflon PFA material in the outside of total screen and forms external sheath layer.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, insulating barrier and restrictive coating have adopted meltable polyflon PFA material in the utility model, and melt flow rate (MFR) 0.2～1.3g/min is easy to process; Tensile strength 〉=25MPa (23 ℃), elongation at break 〉=300%, mechanical strength height; 302～310 ℃ of fusing points (DSC method), temperature resistant grade reaches 250 ℃; Dielectric constant 2.0～2.2 (1MHz), dielectric loss angle tangent≤5 * 10
-4(1MHz), specific insulation 〉=1 * 10
16Ω cm (23 ℃), the material superior electrical property;
2, the meltable polyflon PFA in the utility model material is lower than ad eundem exotic material polyimides PI or polyether-ketone PEK or polyether-ether-ketone PEEK or polysulfones PES price, and economic advantages are obvious;
3, the material of the meltable polyflon PFA in the utility model has high flame retardant, and oxygen index reaches more than 95%;
4, insulation and external sheath layer adopt meltable polyflon PFA material in the utility model, have humidity, adapt to high salinity, superior corrosion resistance energy, are dissolved in any solvent hardly; Weatherability does not absorb water, does not glue oil, and radiation hardness is splendid, and as exposing in atmosphere for a long time, its surface and every performance remain unchanged substantially;
5, adopt the total shielding of tinned copper wire braiding in the utility model, shield effectiveness is good, has extraordinary flexibility.
Description of drawings
Fig. 1 is the utility model heat-resistance type compensating cable for thermocouple structure chart.
Number in the figure: 1 alloy silk conductor, 2 insulating barriers, 3 pair twist groups, 4 unit sheaths, 5 unit pair twist groups, 6 cable cores, 7 belting layers, 8 total shielding drainage threads, 9 total screens, 10 external sheath layers.
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment
In the present embodiment, adopt seven pair twist groups.Just, negative pole alloy silk conductor 1 adopts single or many alloy silk conductor lay configuration, just, extrude on the negative pole alloy silk conductor 1 and form meltable polyflon PFA insulating barrier 2 formation insulated wire cores, whenever just, negative pole two thoroughly does away with the edge core and is twisted into pair twist group 3, on pair twist group 3, extrude PFA unit sheath 4 and constitute unit pair twist group 5 with this, unit pair twist group 5 is arranged stranding in order constitute cable core 6, form belting layer 7 at the wrapped poly-Teflon tap of the outer surface of cable core 6, the total screen 9 of braiding tinned copper wire on belting layer 7 and total shielding drainage thread 8 extrudes meltable polyflon PFA material in the outside of total screen 9 and forms external sheath layer 10.
