Description
Technical field
The present invention relates to electric submersible pump machine technology field, particularly relate to a kind of temperature detection monitoring type electric cable of submersible pump.
Background technology
In the process that electric submersible pump machine uses, along with the oil mass inside oil well reduces gradually, liquid level reduces gradually and finally causes liquid level lower than oil-immersed pump motor height, and the electric cable of submersible pump be connected with oil-immersed pump motor uses terminal true None-identified this point phenomenon, can not cut off the electricity supply in time, thus idle running phenomenon is finally burnt and is scrapped to cause oil-immersed pump motor to occur.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of temperature detection monitoring type electric cable of submersible pump.
The present invention is achieved by the following technical solutions:
A kind of temperature detection monitoring type electric cable of submersible pump, include pressure gauge cable conductor, compensating cable cable core and electric cable of submersible pump cable core, described pressure gauge cable conductor includes conductor one, described conductor one is closed by 7 soft copper skein silks and forms, be coated with polypropylene insulation layer in the outside of conductor one, will polypropylene sheath one be coated with after three a branch of strands of conductor in outside successively, hold lotus armor steel wire floor and polypropylene oversheath; Described compensating cable cable core includes conductor two, and described conductor two adds corronil tow strand by NI-G and forms, and is surrounded by polypropylene insulation layer, is surrounded by silicon rubber oversheath by after two conductor two pair twists in outside outside conductor two; Described electric cable of submersible pump cable core includes conductor three, described conductor three is twisted by oxygen-free copper tow and forms, polypropylene insulation layer, polypropylene sheath two and oil resistant bed course is coated with successively in the outside of conductor three, described oil resistant bed course is made up of polytetrafluoroethylene film lapping layer and kevlar fiber braid, a pressure gauge cable conductor, three electric cable of submersible pump cable cores and a compensating cable cable core is placed side by side successively and is coated with steel-tape armouring layer in outside.
Insulating barrier outside described conductor two and conductor three is rubber insulation; Two posterolateral oversheaths of conductor two pair twist are fluoroplastics oversheath.
The described lotus armor steel wire floor that holds is stranded by the high-strength galvanized steel wire of 72A or 82B.
What pressure gauge cable adopted is three-core structure, and three core energisings, cover wire ground connection, adopt single layer of wires structure, the insulation booth sheath matters of cable use for a long time in oily alkali environment.
1. conductor: pressure gauge cable conductor is closed by 7 soft copper skein silks and forms, the cross section 0.50mm2 of conductor; Compensating wire conductor selects NI-G to add the material of Contra wire according to the Graduation Number of adapted thermocouple; Electric cable of submersible pump conductor is oxygen-free copper material, whether zinc-plated decides conductor according to isolation material.
2. insulate: pressure gauge cable insulation material selects polypropylene, can ensure that the temperature resistant range of product is at-30 ~ 150 DEG C; Compensating wire insulation can select silicon rubber or fluoroplastics; Electric cable of submersible pump insulation can be polypropylene, also can be rubber.
3. sheath: the sheath of electric cable of submersible pump can select material according to environment for use.
4. bed course: oil resistant, is made up of polytetrafluoroethylene film lapping layer and kevlar fiber braid.
5. hold lotus armor steel wire:: the high-strength galvanized steel wire of pressure gauge cable armor material selection 72A or 82B is stranded to be formed, and tensile strength reaches 20kN.
6. sheath: what pressure gauge cable adopted is special modified polypropylene, and this material prescription considers oil resistant, acidproof, Salt And Alkali Tolerance, plays the incorrosive effect of protection armor steel wire; Compensate conductive jacket and can select silicon rubber or fluoroplastics.
7. armour: electric cable of submersible pump armour is steel band (zinc-plated, Monel, stainless steel) lock armo.
On the one hand, downhole flow measurement system-specific cable is connected with terminal fitting and can be used for measuring the oil mass in oil well, staff just can know the oil mass of down-hole according to the data on instrument, when oil mass height just can give the alarm lower than instrument during oil-immersed pump motor, staff just can powered-down, stop oil-immersed pump feeding electric motors, oil-immersed pump motor just can quit work in time, avoids situation about dallying to occur.
On the other hand, the application of thermocouple compensating wire can measure the temperature of oil-immersed pump motor.The working temperature of oil-immersed pump motor under liquid and the working temperature under exposed environment have very big-difference, once the liquid height in oil well is lower than oil-immersed pump motor height, the temperature of motor will raise gradually, compensating wire can the temperature of Measurement accuracy motor, once the words that temperature value raises just can in terminal identification, the generation that oil-immersed pump motor also can be avoided to dally of cutting off the electricity supply in time.
Advantage of the present invention is: the present invention adds downhole flow measurement system-specific cable and compensation lead of thermocouple on the basis of original electric cable of submersible pump; motor in oil well is served to the effect of duplicate protection; idle running is avoided to provide two-layer safeguard measure to oil-immersed pump motor; if one of them measure was lost efficacy still can not affect the normal performance of another safeguard measure function; its use greatly can improve the service efficiency of oil-immersed pump motor, and the life-span also can be extended.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
