OIL BOTTOMHOLE PUMP CATHODE PROTECTION DEVICE |
摘要 |
FIELD: electrical engineering.SUBSTANCE: oil bottomhole pump cathode protection device contains a transformer with primary and secondary windings, the secondary winding outputs collected to the electric motor windings inputs via a cable line. The transformer secondary winding neutral conductor is connected (via a choke) to a DC supply linked to the casing column while the electric motor windings neutral conductor is connected to the electric motor housing and the oil pump housing. The device is equipped with a overvoltage suppressor inserted between the transformer secondary winding neutral conductor and the casing column.EFFECT: spreading of technical measures range.1 dwg |
