Description
Technical field
The utility model relates to a kind of high withstand voltage high-precision profound hypothermia thermopair that has.
Background technology
Thermopair is a temperature element commonly used in the temperature measuring instrument, is conductor two ends by two kinds of heterogeneities when being bonded into the loop, when two abutment electric thermo-couple temperatures not simultaneously, will in the loop, produce thermocurrent.When if the working end of thermopair and reference end have the temperature difference, Displaying Meter will indicate the pairing temperature value of thermoelectrical potential that thermopair produces.The moving heat of the thermoelectricity of thermopair will and increase along with the rising of measuring junction temperature, and its size is only relevant with the temperature at thermocouple material and two ends, and will be irrelevant with length, the diameter of thermode.The profile of various thermopairs is often far from it because of needs, but their basic structure is roughly the same, is made up of major parts such as thermode, insulation sleeve protection tube and terminal boxes usually, common and Displaying Meter, the supporting use of recorder and electronic controller.
Along with the development of domestic spationautics, the particularly successful development of Long March series thrust-augmented rocket and application promoted the development that profound hypothermia (270 ℃ ~ 0 ℃) is measured engineering.To liquid hydrogen is the space power system of fuel and the thermometric of fueling system, should adopt the profound hypothermia thermopair product of respective capabilities.It will possess high measurement accuracy, high anti-working pressure, respond characteristics such as fast.
At existing thermopair, its range of application receives certain restriction, and such as when the profound hypothermia, the use of thermopair just receives very big restriction, can not both guarantee high leakproofness, can under the height vibration, go to measure temperature very quickly and accurately again.On the existing market, do not satisfy the thermopair of this requirement yet, thus the research and development of this series products be badly in need of, to satisfy the technical requirement of particular client crowd under profound hypothermia, measuring with high precision thermopair product!
By on can know that addressing these problems is extremely urgent!
In view of this, the inventor has done deep research, and by feat of the experience of being engaged in relevant industries for many years and practice; Design a kind of high withstand voltage high-precision profound hypothermia thermopair that has; Can solve deficiency of the prior art, exquisiteness simple in structure, stable performance; Have characteristics such as withstand voltage height and precision height at the profound hypothermia thermometric, this case produces thus.

Further, the inside of said bar is provided with low temperature glue, is provided with thermo wires in the inside of low temperature glue;
Further, said shielding extension line passes tamponade, is connected setting with thermo wires;
The beneficial effect of the utility model: the utility model comprises the bulb body; Side at the bulb body is provided with bar, is provided with gland nut at the bulb body near an end outside of bar, is provided with the shielding extension line at the opposite side of bulb body; The bulb body near the shielding extension line an end inside be provided with tamponade, the outside is provided with the compacting cap; Between shielding extension line and compacting cap, be provided with spring, adopt above-mentioned setting, when the utility model uses in profound hypothermia; Have high pressure resistant and the high characteristics of precision, satisfied the technical requirement of particular client crowd under profound hypothermia, measuring with high precision thermopair product.
The utility model product basic mechanical design feature index has:
1, measures temperature-270 ℃～0 ℃;
2, accuracy class: ± 0.3 ℃;
3, air pressure resistance: 25Mpa;
4, normal temperature insulation resistance >=500M Ω/500VDC;
5, bonding resistance≤0.05 Ω;
By on can know, the utility model exquisiteness simple in structure, stable performance has characteristics such as withstand voltage height and precision height at the profound hypothermia thermometric.
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
