A kind of insulating protective metal shell of mineral thermocouple compensating wire
The utility model relates to cable production art, specifically a kind of insulating protective metal shell of mineral thermocouple is led with compensation
Compensating wire is that have and matched hot thermocouple electromotive force same nominal for (0-100 DEG C) in certain temperature range
A pair of value has the conducting wire of insulating layer, thermocouple and measuring device is connected with them, to compensate they and thermocouple junction
Temperature change caused by error, current compensating wire because the material temperature resistant grade used is lower, cause cable be applicable in
Occasion is limited, existing market technological progress, and need premise temperature to be used is higher and higher, the machinery that cable can bear is answered
The requirements such as power are also higher and higher, and common product is not able to satisfy the use of specific occasion.
To solve the above-mentioned problems, the utility model is proposed, so that the utility model has the function of conventional compensating cable
Outside, it is also equipped with and is being lower than 1000 DEG C of hot conditions, slight radiation condition, is weighing the characteristic used under oil pollution environment, be conducive to height
The development of warm special trade.
Utility model content
The purpose of this utility model is to provide a kind of insulating protective metal shell of mineral thermocouple compensating wires, on solving
State the problem of proposing in background technique.
To achieve the above object, the utility model provides the following technical solutions:
A kind of insulating protective metal shell of mineral thermocouple compensating wire, the conductor including the setting of bosom position are described
The outside package of conductor is provided with insulating layer, and the outside package of insulating layer is provided with shielded layer, and the conductor is several thin copper wires
Or alloy wire carries out regular process and forms, the insulating layer is mica and the glass fiber mixing of conductor outside surfaces covering setting
The conductor of insulating materials, the package insulating layer and shielded layer is by also wrapping up setting external after filling mineral powder process stranding
There is insulating layer.
As a further solution of the present invention: the shielded layer be several process insulated wire be woven into it is wrapped
Metal tape or establishment wire.
The outside package of outermost insulating layer is provided with metallic sheath as a further solution of the present invention, and
Metallic sheath protective layer is provided on the outside of metallic sheath.
Compared with prior art, the utility model has the beneficial effects that making the utility model that there is conventional compensation electricity
Outside cable function, it is also equipped with and is being lower than 1000 DEG C of hot conditions, slight radiation condition, is weighing the characteristic used under oil pollution environment, have
Conducive to the development of high-temperature special industry.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of conductor in insulating protective metal shell of mineral thermocouple compensating wire；
Fig. 2 is a kind of schematic cross-sectional view of insulating protective metal shell of mineral thermocouple compensating wire.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1,2, in the utility model embodiment, a kind of insulating protective metal shell of mineral thermocouple compensating wire,
Conductor 3 including the setting of bosom position, the conductor 3 are that several thin copper wires or alloy wire carry out regular process and form,
The outside package of the conductor 3 is provided with insulating layer 2, and the insulating layer 2 is the mica and glass of 3 outer surface of conductor covering setting
The insulating materials of silk mixing, the outside package of insulating layer 2 are provided with shielded layer 1, and the shielded layer 1 is the insulation of several process
The conductor 3 of the wrapped metal tape or establishment wire that line is woven into, the package insulating layer 2 and shielded layer 1 passes through filling ore
External also package is provided with insulating layer 2 after the process stranding such as powder, the outside package of outermost insulating layer 2 is provided with metallic sheath
4, and the outside of metallic sheath 4 is provided with metallic sheath protective layer 5.
The working principle of the utility model is: several thin copper wires or alloy wire, which are carried out regular process, is made conductor 3, and
In the outside of conductor 3 package setting insulating layer 2, since insulating layer 2 is that mica and glass fiber etc. are mixed, insulation effect is more
Good, the outside of insulating layer 2 is provided with shielded layer 1, the wrapped metal tape that shielded layer 1 is woven into using the insulated wire of several process
Or establishment wire, combination shield effectiveness is good, and the conductor 3 for wrapping up insulating layer 2 and shielded layer 1 is stranding by filling mineral powder etc.
External also package is provided with insulating layer 2 after cable, the outside package of outermost insulating layer 2 is provided with metallic sheath 4, and metallic sheath
4 outside is provided with metallic sheath protective layer 5, so that the utility model has the function of to be also equipped with outside conventional compensating cable low
The characteristic used under 1000 DEG C of hot conditions, slight radiation condition, weight oil pollution environment, is conducive to the hair of high-temperature special industry
