Borets-11Ì1   "Borets-11M1" is the improved model of switchboard equipped with a new generation controller "Kaskad 2-200". Measurement of operating parameters is performed at a low-voltage side of transformer. High-voltage cables are not connected to the switchboard, which simplifies installation and ensures better maintenance safety. Current calibration is executed directly in the display of parameters. The small cabinet is lifted up high on two support feet with big stability platform, thus ensuring convenient cable rooting and connection. There are switchboard modifications with cable connections at switchboard lower and rear parts in a separate compartment. "Kaskad 2-200" controller contains all required sources of power supply, metering and input circuits. So, switchboard has absolutely no control circuits and comprises only power elements. This allowed make switchboard in small dimensions that simplifies operation and repair works in field conditions. Switchboards are equipped with LCDs and energy independent memory. Information on motor operation is transmitted to a two-row display in Russian or English. The controller memory keeps information of 63 last reasons for starts and stops. Volume of memory allows keep 32768 parameter records of ESP operation. Also, the memory keeps date and time of each set value change along with previous and current set values. Data required for further processing, can be read by a portative computer, reading and data input blocks or transmitted to the system of telemetry by means of standard RS-485 interface. Switchboard can be connected to any type of underground telemetry. Controller automatically determines type of downhole sensor, reads information from it and controls and protects set values of pressure, temperature and vibrations. Borets-01UMV   Switchboards of this type are improved “Borets-01MV” switchboards by means of installation of controller model “Kaskad2-200”. It allowed significantly simplifying power part of the switchboard, enlarging its functional capabilities, improving maintainability and simplifying servicing. Operational capabilities of the switchboard are the same as for the switchboard “Borets-11Ì1”. Switchboards are manufactured to fit currents 250, 400 and 630 À. A switchboard with a built-in soft starter can be supplied (model “Borets- 01UMVP). Connection of power cables is done through a separate compartment at the upper rare part of the cabinet. Borets switchboards are compatible with downhole sensor of any manufacturer. Borets-12   Advantages of the small-size switchboard: - switchboard can be installed on the top of the TMPN transformer tank (installation can be done on transformers of different manufacturers); - moving, assembling, installing and servicing of the switchboard can be done by one person without any hoisting devices (switchboard weight is less than 110 lb (50 kg) for 250 A switchboard); - can be transported in the boot of "Niva" VAZ-2121 car. Control and protection is done by the controller of new generation "Kaskad2-200", so the functional capabilities of the switchboard are the same as for "Borets-11M1" switchboards.
