Description

The invention relates to cabinet complete devices, in particular to cabinets of control stations for motors of electric centrifugal pumps, and can be used for the production of formation fluid using pumps.

Known cabinets of a submersible electric pump control station, containing a housing with a door, which houses the power equipment, openings for cable entry, an air cooling device, a panel of controls and displays (see, for example, RF patent for utility model No. 33834 according to IPC H02B 1 / 00, publ. 10.11.2003 and RF patent for utility model No. 46617 according to IPC H02P 7/42, publ. 1.07.2005).

The closest in technical essence is the cabinet of the submersible electric pump control station, containing a housing with a door, which houses a frequency converter with a cooling radiator, power equipment, openings for cable entry, an air cooling device with a fan, a control and display panel, and inside the cabinet is installed step-up transformer, the roof of the cabinet is made of lower and upper sections, and the upper section is made of a solid U-shaped type, and the lower section has holes for hot air outlet from the cabinet to the inner area between the upper and lower sections, in addition, the structural design of the roof provides further outlet of hot air to the environment, the frequency converter unit is installed on shelves formed by two brackets fixed on a mounting panel, which is fixed on the inner side of the rear wall of the cabinet (see RF patent for utility model No. 46617 according to IPC H02P 7/42, publ. 1.07.2005.).

In the known cabinet, the frequency converter is located completely inside the cabinet, heat is removed from the cabinet by means of an additional fan located in the cabinet, such a system worsens the heat removal from the frequency converter and reduces the reliability of its operation. The disadvantage of the known cabinets is the laboriousness of fastening during installation, where, in cramped conditions, it becomes necessary to place a cabinet weighing from 20 to 50 kg on various types of walls. This disadvantage of the known cabinets also makes it difficult to dismantle when carrying out maintenance and repairs when replacing defective elements. Known cabinets are difficult to hang for one installer, since it is necessary to hang the cabinet on all four fasteners at once. Known cabinets require parameterization and commissioning by a qualified specialist, which is difficult to organize in rural areas, where submersible pumps are usually used.

The technical result achieved in the claimed invention is to increase the reliability of work, simplify the maintenance of equipment and perform repairs, simplify installation and commissioning.

The technical result is achieved by the fact that in the cabinet of the submersible electric pump control station, containing a housing with a door, which houses a frequency converter with a cooling radiator, power equipment, openings for cable entry, as well as a panel of controls and indication, according to the invention, the cabinet is additionally equipped with a the rear wall of the housing with a support-hinged segment of a box-shaped form with lattice windows on the side walls and holes for hanging, the cooling radiator of the frequency converter (3) is fixed in a window made in the rear wall of the housing, located inside the support-hinged segment, the rear wall is equipped with a baffle plate for separation of warm and cold air flows inside the support-hinged segment. The supporting-hinged segment is fastened to the body by means of hinged plates with fixing slots. The support-hinge segment is equipped with a bubble liquid level for level installation. The body is equipped with a false panel fixed on the inner surface of the rear wall. The cabinet is equipped with GSM communication, equipment for remote parameterization, adjustment and operation control.

The essence of the invention is illustrated by schematic drawings.

FIG. 1 shows a cabinet with a slightly open door, front view; in fig. 2 shows the cabinet, side view; in fig. 3 - wardrobe, rear view; in fig. 4 shows a fragment explaining the location of the hinged cover.

The cabinet of the submersible electric pump control station contains a housing (1) with a door (2), which houses a frequency converter (3) with a cooling radiator, power equipment (4), openings for cable entry (5), as well as a control and display panel ( 6). The cabinet is equipped with a box-shaped support-hinged segment (7) attached to the body (1) from the back with lattice windows (8) on the side walls (9) and hanging holes (10). The cooling radiator of the frequency converter (3) is fixed in a window made in the rear wall (11) of the housing (1), located inside the support-hinged segment (7). The rear wall (11) is equipped with a baffle plate (12) for separating warm and cold air flows inside the support-hinged segment (7). For the convenience of horizontal orientation, the support-hinged segment (7) is equipped with a bubble liquid level (13) for level installation. The body (1) is equipped with a false panel (14) fixed on the inner surface of the rear wall (11). The terminal block (15) is located in the lower part of the housing (1). The supporting-hinged segment (7) is fastened to the housing (1) by means of attachment plates 16 with fixing slots 17 attached to the side walls of the housing 1, located when hanging between the screw heads 18 and the side walls 9. The cabinet is equipped with GSM communication, equipment for remote parameterization.

The cabinet is used as follows.

In the initial position, before mounting the cabinet on the wall of the station room, the support-hinged segment (7) is separated from the housing (1).

The installation of the cabinet on the wall begins with fixing the support-hanging segment (7) to the wall by hanging it on the brackets fixed on the wall using the hanging holes (10). The horizontal orientation of the support-hinged segment (7) for its even installation is controlled by a bubble liquid level (13).

Then, to the support-hinged segment (7) installed on the wall, on the screws (18) using hinged plates 16 with fixing slots (17), the body (1) is hung, followed by fixing with screws (18), tightly pressing the hanging plates (16) to the side the walls 9 of the support-hinged segment (7), thereby realizing reliable fastening.

After mounting the cabinet, the cooling radiator of the frequency converter (3) is located inside the cavity formed by the walls of the support-hinged segment (7), the wall of the room and the rear wall of the housing (1). Inside the support-hinged segment (7) there is also a baffle plate (12), which separates the air flows from the fan of the frequency converter (3) and the cooling air entering through the corresponding lattice window (8), forming an effective air exchange. The presence of a false panel (14) excludes touching the terminals and live elements. Removing the cooling radiator of the frequency converter (3) outside the housing 1 makes it possible to exclude the fan, which is additionally installed in such cabinets and is a unit with an increased failure rate.

The design of the proposed cabinet allows the installation to be carried out by the operating organization independently without a commissioning specialist visiting the facility. All operations requiring special knowledge are performed remotely via GSM communication networks.
