Switchboards of series ELEKTON-04

Purpose and application

Switchboards of series ELEKTON-04 are assigned to operate as a part of electric rotary pump installation for oil extraction, for deep-well working sucker-rod pumps, for stratal water injection, water scoop etc.

Functional capabilities

Elekton-04 Switchboards are designed for control and protection of the ESP motors.

Current measurement in Elekton-04 Switchboards is carried out in step-up transformer primary circuit; results are being converted into motor operating current by controller with a special program. Due to such design the input of cables from secondary circuit of step-up transformer is eliminated, that enables to facilitate mounting noticeably and to increase operation safety.

There is possibility to link-up to telemechanics through RS-485 port (protocol Modbus supported). Switchboards operating data can be transmitted into notebook for following treatment, analysis and storing in the data base.

In Elekton-04M-250 (400) Switchboard in contrast to Elekton-04-250 (400) Switchboard,the power circuit’s flexible contactor has been substituted for copper bus.Elekton-04-250 (400) Switchboard has been provided with a possibility of soft starter.

Certificate of conformance RU C-RU.ME68.B.00008/19.

Features

• Cables are connected in special section mounted on the cabinet’s back board upper part. Such design facilitates assembling of the switchboard on the multiple well platforms. This design is covered by several patents.



• 0,4 kV cable clamps provide connections up to 3 cables (with section 95 mm²) or up to 4 cables (with section 120 mm²) for each phase.



• Switchboard’s design is highly maintainable and has safe production service: system’s crucial components are easily substituted due to the plug-type connections application and engineering solution.



• Special sections for external devices connection unit are mounted on the cabinet’s back side of the switchboards as well as connection terminal of neutral point of the step-up transformer’s secondary coil. This design facilitates all external connections without opening the switchboard.



• USB-port for data retrieval into the standard USB Flash Drive.



• Electric power metering by Switchboard controller or built-in sensor



• There is a window on the switchboard cabinet’s front door, opposite the controller’s indicator lamps informing about switchboard’s status. Such design facilitates the control of the switchboard’s status without opening the door.
