Description

Device object

A set of ground equipment for installation and installation of electric centrifugal pump installations

The utility model relates to the field of energy, in particular to the designs of oil transformers and control stations used to power and control electric centrifugal pump units.

Known sets of ground-based equipment for installing an electric centrifugal pump (UECP), in which an oil submersible pump transformer (TMPN) and a control station (SU) are installed next to each other on a base frame.

The closest to the claimed object in technical essence is the usual set of ground equipment of the ESP, consisting of TMPN and a control station installed on a single base frame and connected to each other by jumper cables. (1)

However, the well-known set of ground equipment of the ESP has a number of drawbacks, the main of which is the presence of a frame and connecting cables. This drawback arises from the use of the bulky casing of the control station, which makes it impossible to install the control station on the TMPN and the exclusion of connecting cables. In the process of replacing such a set of ground equipment, the ESP has to either take out the cumbersome to the well) then the frame with the installed TMPN and the control station, or replace them individually in the field, which is difficult, especially in winter. The cost of the bulky casing of the control station and the base frame, the presence of long connecting cables between the control system and the TMPN is also a drawback, expressed in an increase in the cost of a set of ground equipment of the ESP, the costs of its replacement, as well as the large overall dimensions.

The technical task of developing a utility model is to increase the quality of the design, reduce the cost of a set of ground-based equipment of the ESP and the costs of its manufacture, operation, installation / dismantling, increase the security of the set of ground-based equipment of the ESP from unauthorized entry.

This goal is achieved by the fact that a compact control station based on the controller is installed directly on the TMPN cover, while being its terminal box, which eliminates the need for a bulky base frame and long jumper cables. In the study of the distinguishing features of the described set of ground-based ESP equipment, no known similar solutions were identified.

The useful model is illustrated by drawings.

The drawing (figure 1) shows the location of the compact control station on the cover TMGSh. On base ski 1, an oil transformer TMPN 2 with a high-voltage compartment 4 is installed, which is the basis for the low-voltage compartment 5 with a controller 6. Voltage is applied at 380 V via cable 7, the engine is powered by cable 3. Low-voltage compartment 5 and high-voltage compartment 4 more are presented in detail in figure 2 and contain the release 8, the contactor

9, fuse box 10, high voltage insulators 11.

A set of ground equipment for ESP works as follows.

Power is supplied to the release 8, then to the fuse box

10, then to the contactor 9, after which the voltage is supplied to the low-voltage insulators TMPN by the tires. Further, from the high-voltage insulators 11, the voltage is supplied to the well. The control signals are removed from the current-carrying tires and fed to the controller 6.

of equipment assembled on a bulky base frame, in particular, the dimensions of the ground equipment set of ESPs will be reduced, the assembly / disassembly of the kit at the well will be simplified, the productivity of the electrician team will increase, and secondly, the process of manufacturing the kit will be simplified and cheaper, the search for the ground kit will increase equipment from unauthorized access.
