SURGE-SUPPRESSION SYSTEM FOR SUBMERSIBLE ELECTRIC MOTORS

摘要

A submersible motor having electrical-surge protection. The submersible motor includes a motor housing formed from an electrically-conductive material; a stator-winding assembly disposed within, and electrically insulated from the motor housing; a power wire for transmitting electrical energy delivered by an external power source to the stator-winding assembly within the housing; and an end ring formed from an electrically-conductive material. The submersible motor further includes a surge-protection assembly having a surge protector that includes two opposing electrode surfaces that are held a distance apart by an insulator and a coupling member formed from an electrically-insulating material. The coupling member abuts the power wire against the surge-protection assembly to establish an electrically-conductive path between the power wire and the surge-protection that is substantially devoid of wires.
