Device for continuous monitoring of insulation resistance of a submersible electric cable and continuous monitoring of the resistance of windings of a submersible electric motor of an electric submersible pump installation

摘要

The utility model relates to test equipment, in particular for continuous monitoring of the insulation resistance of the electric cable of an electric centrifugal pump (ESP). The device for continuous monitoring of the insulation resistance of a submersible electric cable and continuous monitoring of the resistance of the windings of a submersible electric motor of an electric submersible pump installation contains a sealed enclosure with quick-detachable high-voltage reusable terminals. In the housing are a battery connected to a power supply; a central processor module and a gyroscope module, a temperature sensor, a removable non-volatile memory, a GSM module, a measuring module, a star and / or a triangle control module of a submersible motor connected to a central processor module to a local network. The measuring module is additionally connected to the “star” and / or “triangle” control module of the submersible motor. The measuring module is connected to phase A of a three-core submersible electric cable, the control module of the "star" and / or "triangle" of the submersible electric motor is connected to phases A, B and C of a three-core submersible electric cable. Using the utility model, the accuracy of the constant monitoring of the insulation resistance of the submersible cable of an electric submersible installation can be improved performing tripping operations of the electric centrifugal pump in oil and gas producing wells, as well as providing continuous monitoring of the star connection and / or “triangle” windings of a submersible motor. 8 s.p. f-ly, 5 ill.
