Electrical Submersible Pump System Having High Temperature Insulation Materials and Buffered Lubricant |
摘要 |
Electric submersible well pumping systems operable in well temperatures of above about 180° C. (356° F.) utilize high temperature electrical insulation. The electrical insulation includes E-base polyimide films or perfluoropolymer TE films on various components. The insulation films are employed around magnet wires that are threaded through slots in the stator. Slot insulation of E-base polyimide or perfluoropolymer TE film surrounds the magnet wires in the stator slots. Sheets of E-base polyimide or perfluoropolymer TE film extend around and between phase loops of the magnet wire at the lower end of the stator. The motor contains a PAO oil having additives to dissipate acid generated by epoxy used in the motor. |
