Abstract
A leading cable head of an electrical submersible pump is used for connecting an electrical submersible pump cable and a submersible motor. An insulating gland is fixed at one end of a central hole of a housing via a screw, three through holes are arranged on the insulating gland in the shape of a triangular, three plugs are respectively plugged into the through holes, the central hole of the housing is filled with insulating material, the insulating material separates inner ends of the three plugs, internal screw threads are arranged at inner ends of the three plugs, end portions of three conductors are respectively threaded with the inner ends of the plugs, epoxy resin is perfused in the central hole of the housing, the epoxy resin separates the conductors, and the other end of the central hole of the housing is provided with a tin-lead alloy cap. Effects of the leading cable head are that the cable head can not leak under a high temperature environment, period for detecting the pump is prolonged, and pump detection cost is reduced.
Description
Technical field
The utility model relates to down-hole, oil field submersible electric pump technical field, and particularly oil-submersible cable is a kind of submersible electric pump motor leading and connecting cable end with the device that submersible electric machine with oil is connected in the submersible electric pump.
Background technology
Submersible electric machine with oil on the submersible electric pump of down-hole, oil field is connected with oil-submersible cable, for submersible electric machine with oil provides electric energy.The jump lead head be oil-submersible cable with submersible electric machine with oil between the particular component that is connected.Can the structure quality of jump lead head will directly have influence on unit and normally move.Because the jump lead head is with the same long-term work of electric pump unit in the down-hole about 2000 meters, and is in high temperature, high pressure, corrosivity oil gas and unit for a long time and trembles in the middle of the environment, thereby require the jump lead head should have higher electric property and mechanical performance.Because receive the restriction of casing inner diameter, it is excessive that the volume of jump lead head can not be done.The jump lead head product that domestic manufacturer produces, can adapt to formation temperature 90 ℃ with interior down-hole, and the unit internal temperature is in 120 ℃.And the formation temperature of some oil field oil reservoirs is more than 120 ℃, and the motor internal temperature of submersible electric pump reaches more than 150 ℃, so homemade submersible electric machine with oil jump lead head heatproof index does not reach underground requirement.
The utility model content
The purpose of the utility model is: a kind of submersible electric pump motor leading and connecting cable end is provided, can realizes being connected between oil-submersible cable and the submersible electric machine with oil, be fit to the high temperature resistant jump lead head that 138,116,95 types series submersible electric machine with oil uses.
The technical scheme that the utility model adopts is: submersible electric pump motor leading and connecting cable end; Mainly form by conductor, terne metal capping, housing, epoxy resin, insulating packing, insulation gland and plug; Tubular housing has centre bore; On an end outer wall of housing, the annular terminal pad is arranged, on terminal pad, be symmetrically distributed with two fixing holes, can housing be fixed on the submersible electric machine with oil shell through screw.It is characterized in that: an end of housing centre bore has internal thread, is fixed with an insulation gland at the threaded one end of housing centre bore; The through hole that distribution triangular in shape is arranged on the insulation gland, three plugs are inserted in respectively in the through hole of insulation gland; In the housing centre bore, be filled with insulating packing, insulating packing is separated the inner of three plugs; The inner at three plugs has internal thread respectively, and the end of three conductors is connected to plug the inner through screw thread; In the housing centre bore, also be perfused with epoxy resin, epoxy resin is separated conductor; The other end at the housing centre bore has the terne metal capping, and three conductors pass the terne metal capping respectively.
What described insulating packing adopted is fluoroplastics.Through preferred encapsulant, improve submersible electric pump motor leading and connecting cable end resistance to elevated temperatures.
The beneficial effect of the utility model: the utility model submersible electric pump motor leading and connecting cable end, through test, motor leading and connecting cable end each item index reaches requirement, and cable end can not leaked under hot environment.1) DC break down voltage leak check, leakage current≤15 μ A 5min.2) insulation resistance >=2000M Ω.3) oil pressure testing, oil pressure 0.5MPa, 5min does not leak.4) resistance to elevated temperatures: during operating ambient temperature≤150 ℃, useful life>=360 day prolong pump detection period, pay the pump detection and workover expense less.
