Description
Technical field
The utility model relates to compensation circuit, specifically a kind of stainless steel sheath mineral insulation compensating wire belongs to
Field of cable technology.
Background technique
Compensating wire is that typically in certain temperature range (0 ~ 250 DEG C) with identical as matched hot thermocouple electromotive force
A pair of nominal value has the conducting wire of insulating layer, connects thermocouple and measuring device with them, coupled with thermoelectricity to compensate them
Connect error caused by the temperature change at place.And each different alloy material of use in this pair of conductor.
In the common structure of compensating wire, then Yi Leishi, insulating layer has insulating layer this two using plastics are extruded
Conductor be twisted or be placed in parallel, increase oversheath when necessary；This kind of compensating wire because being limited by plastics heat resistance,
Generally up to it is no more than 250 DEG C using temperature.It is another kind of to be, two conductors of a pair of of different-alloy material, respectively with multiple
It is together in series containing foraminate ceramic section, to obtain certain bending property and better high temperature resistance, the disadvantage is that ceramic
The concatenated insulating layer of section is discontinuous, and the conducting wire that conductor contacts and loses temp sensing function or other circuits is easy to happen when by external force
It is contacted with the conductor of compensating wire and Electrical Safety accident occurs.
For the above-mentioned technical problem for overcoming compensating wire, safe and reliable measurement temperature when higher temperature is solved, is mentioned herein
For a kind of compensating wire of novel protective.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, and it is exhausted to provide a kind of stainless steel sheath mineral
Edge compensating wire, the compensating wire make compensating wire simultaneously using the structure of stainless steel sheath, the compensating wire of mineral insulation
Have the characteristics that tension, resistance to compression, heat-resisting quantity is good, chemical corrosion resistance is good, good bending property, it is safe and reliable, cost compared with
It is low, it is suitble to industrial application, there is higher utility value in industry.
To realize the above technical purpose, the technical solution of the utility model is: stainless steel sheath mineral insulation compensating wire,
Conductor including two unlike materials, which is characterized in that the conductor separation of two unlike materials is distributed in stainless steel tube,
Mineral insulation is filled up between the conductor of two unlike materials and between conductor and stainless steel tube.
Further, sheath is additionally provided with outside the stainless steel tube.
Further, the material of the sheath is composed of glass fiber and inorganic matter gluing.
Further, the material of the mineral insulation includes magnesia.
Further, the conductor of two unlike materials is axially arranged in stainless steel tube along stainless steel tube.
The utility model has the advantage that
1) the utility model proposes stainless steel sheath mineral insulation compensating wire, stainless steel tube is set outside conductor, no
The intensity of rust steel pipe is high, keeps the mechanical and physical performances such as tension, resistance to compression, the bending of compensating wire more preferable, while chemical stability is more
Good, its antiseptic property is stronger under the environmental conditions such as most of chemical corrosivity substance, salt fog, humidity；
2) the utility model uses the fusing point of mineral insulation higher (fusing point of such as magnesia is 2800 DEG C), compensating wire
In the permitted melting temperature of conductor is not achieved in environment temperature alloy material, compensating wire is not damaged, even if leading
The wiring circuit contact of line and other electric appliances and the contingency for leading to high pressure moment breakdown mineral insulation, the mineral at breakdown point
It does not change still even if insulator 3 melts its chemical component, after the breakdown voltage of application is eliminated, insulation performance will not be generated
Variation, may continue to normal use；
3) stainless steel sheath mineral insulation compensating wire, having makes compensating wire while having that heat-resisting quantity is good, chemically-resistant
The features such as corrosivity is good, good bending property, using safe and reliable, cost is relatively low, is suitble to industrial application, has industry
Upper higher utility value.
