CN203098361U - Reactive power compensator of submersible electric pump - Google Patents

Abstract

The utility model provides a reactive power compensator of a submersible electric pump, which comprises an upper cover, a lower cover, a plug, screws, leads, a reactive power compensation element and insulating oil, wherein the upper cover and the lower cover are in threaded connection; the reactive power compensation element is placed in a casing, and insulating oil is poured in; the upper cover is provided with the plug, and fixedly connected with the plug through the screws; and the leads of the reactive power compensation element penetrate through the upper cover and the plug. The reactive power compensator can be mounted underwater to perform in situ compensation for the submersible motor, therefore, active loss of a conducting wire above the submersible electric pump caused by reactive current delivery is reduced, further, not only is the usage quantity of electric wires reduced, but also the reactive loss of the current is reduced, and resources and energy are saved.

Description

Submersible pump reactive power compensator

technical field

The utility model relates to the field of electric facility protection, in particular to a reactive power compensator for a submersible electric pump.

Background technique

    At present, the reactive power compensation components of the submersible pump reactive power compensator are placed in an iron box without a strict sealing device, and can only be installed and used on the water surface. When using this compensation device, a long wire needs to be extended to be placed underwater , it can only reduce the wire loss above the compensation point, but the wire loss below the compensation point cannot be reduced, and it will not achieve a good energy-saving effect, wasting resources and energy.

Utility model content

In order to overcome the defects of the prior art, the utility model provides a submersible electric pump reactive power compensator with small loss and strong energy saving effect.

The technical scheme of the utility model is: a reactive power compensator for a submersible electric pump, including an upper cover, a lower cover, a plug, a screw, a lead wire, a reactive compensation element and insulating oil, the upper cover and the lower cover are connected by threads, and the shell Reactive power compensation components are placed inside, and insulating oil is poured; the upper cover is provided with a plug, and is fixedly connected to the plug by screws; the lead wire of the reactive power compensation component passes through the upper cover and the plug.

The further improvement of the utility model is that: the top of the upper cover is provided with a groove matching the shape of the blockage.

The further improvement of the utility model is that: several lead wire holes are arranged at the bottom of the groove.

The further improvement of the utility model is that a sealing gasket is inserted between the inner wall of the lead wire hole and the outer wall of the lead wire.

The further improvement of the utility model is that: the bottom of the threaded opening on the lower cover is covered with a sealing ring.

The further improvement of the utility model is that: the inner bottom of the lower cover is provided with a table top matching the bottom of the reactive power compensation element.

A further improvement of the utility model is that: the reactive power compensation element is fixedly connected with the table top by screws.

The beneficial effects of the utility model are: the utility model adopts a sealed shell, which can be installed underwater with the electric pump, and compensates the submersible motor on the spot, reducing the active power loss caused by the reactive current transmission of the wires above the submersible electric pump , not only reduces the use of wires, but also reduces the reactive power loss of current, saving resources and energy.
