Description
Technical field
The present invention relates to electric submersible pump machine technical field, more particularly to a kind of temperature detection monitoring type electric cable of submersible pump.
Background technology
During electric submersible pump machine use, as the oil mass inside oil well is gradually decreased, liquid level is gradually reduced most
Cause liquid level eventually less than latent oil pump motor height, and really can not with the electric cable of submersible pump using terminal of oil-immersed pump motor connection
Recognize this point phenomenon, it is impossible to cut off the electricity supply in time, finally burn-up is scrapped so as to cause latent oil pump motor idle running phenomenon occur.
The content of the invention
The object of the invention is exactly that there is provided a kind of temperature detection monitoring type electric cable of submersible pump in order to make up the defect of prior art.
The present invention is achieved by the following technical solutions：
A kind of temperature detection monitoring type electric cable of submersible pump, includes pressure gauge cable conductor, compensating cable cable core and oil-immersed pump electricity
Cable cable core, described pressure gauge cable conductor includes conductor one, and described conductor one is formed by 7 soft copper silks are stranded,
Polypropylene insulation layer is coated with the outside of conductor one, polypropylene sheath will be coated with successively in outside after three bundle strands of conductor one
First, lotus armor steel wire floor and polypropylene oversheath are held；Described compensating cable cable core includes conductor two, and described conductor two is
By NI-G plus Contra wire bundle strand, polypropylene insulation layer is surrounded by the outside of conductor two, by two pair twists of conductor two
Silicon rubber oversheath is surrounded by outside afterwards；Described electric cable of submersible pump cable core includes conductor three, and described conductor three is by nothing
Oxygen copper wire bundle strand, it is coated with polypropylene insulation layer, polypropylene sheath two and oil resistant bed course successively in the outside of conductor three,
Described oil resistant bed course is made up of polytetrafluoroethylene film lapping layer and kevlar fiber braiding layer, by a pressure gauge electricity
Cable cable core, three electric cable of submersible pump cable cores and a compensating cable cable core are placed and are coated with steel-tape armouring in outside side by side successively
Layer.
Insulating barrier on the outside of described conductor two and conductor three is rubber insulation；Two pair twists of conductor two are posterolateral outer
Sheath is fluoroplastics oversheath.
The described lotus armor steel wire floor that holds is stranded by 72A or 82B high-strength galvanized steel wire.
Pressure gauge cable uses three-core structure, and three cores are powered, cover wire ground connection, using single layer of wires structure, electricity
The insulation booth sheath matters of cable are used in oily alkali environment for a long time.
1. conductor：Pressure gauge cable conductor is formed by 7 soft copper silks are stranded, the section 0.50mm2 of conductor；Compensating wire
Conductor selects the material of NI-G plus Contra wire according to the Graduation Number of adapted thermocouple；Electric cable of submersible pump conductor is anaerobic
Copper material, determines whether conductor is tin plating according to isolation material.
2. insulation：Pressure gauge cable insulation material selects polypropylene, it is ensured that the temperature resistant range of product is -30~150
℃；Compensating wire insulation can select silicon rubber or fluoroplastics；Electric cable of submersible pump insulation can be polypropylene or rubber
Glue.
3. sheath：The sheath of electric cable of submersible pump can select material according to use environment.
4. bed course：Oil resistant, is made up of polytetrafluoroethylene film lapping layer and kevlar fiber braiding layer.
5. hold lotus armor steel wire：：Pressure gauge cable armor material selection 72A or 82B high-strength galvanized steel wire it is stranded and
Into tensile strength reaches 20kN.
6. sheath：Pressure gauge cable uses special modified polypropylene, and the material prescription considers oil resistant, acidproof, resistance to
It is saline and alkaline, play the protection incorrosive effect of armor steel wire；Compensation conductive jacket can select silicon rubber or fluoroplastics.
7. armor：Electric cable of submersible pump armor is steel band（Zinc-plated, Monel, stainless steel）Lock armo.
On the one hand, downhole flow measurement system-specific cable be connected with terminal fitting can for measurement oil well in oil
Amount, staff is according to the data on instrument it is known that the oil mass of underground, the instrument when oil mass is highly less than latent oil pump motor
Device will send alarm, and staff just can close power supply, and stopping is powered to latent oil pump motor, latent oil pump motor just can and
When be stopped, it is to avoid the situation of idle running occurs.
On the other hand, the application of thermocouple compensating wire can measure the temperature of latent oil pump motor.Latent oil pump motor exists
Operating temperature under liquid and the operating temperature under exposed environment have very big difference, once the liquid height in oil well is less than
Latent oil pump motor height, the temperature of motor will gradually rise, compensating wire can accurate measurement motor temperature, once temperature
Just it can be recognized if value rise in terminal, the generation that latent oil pump motor can also be avoided to dally of cutting off the electricity supply in time.
It is an advantage of the invention that：It is special that the present invention adds downhole flow measurement system on the basis of original electric cable of submersible pump
With cable and compensation lead of thermocouple, the effect of duplicate protection is served to the motor in oil well, sky is avoided to latent oil pump motor
Turn to provide two layers of safeguard measure, another safeguard measure function is not interfered with still if one of measure is failed
Normal performance, its use can be greatly enhanced the service efficiency of latent oil pump motor, and the life-span can also be extended.
