INNOVATIVE SOLUTIONS
During the development of the Device, all the problems of previously known systems for blocking operational switching were solved
Most existing interlocks use signals from dry block contacts (DCAs) or reed switches (contact sensor) to collect logic. Dry contacts are susceptible to oxidation, and reed switches are subject to magnetization, which leads to loss of signal and the inability to obtain a reliable position of the device.
The UKBR uses reliable contactless sensors to obtain information about the position of devices.
Electromagnetic interlocking with relay logic, as well as some microprocessor interlocks, require a large number of cable connections.
The UKBR uses only one cable per shaft of the device.
Switching devices which are allowed are marked in green, switching devices which are prohibited are marked in red.
On locks located directly on the spacecraft, an LED indicator indicates the presence of permission to switch.
In some cases, it is necessary to use the position of disconnectors and grounding blades on the connected substation to collect interlocking logic.
UKBR can exchange data on the position of devices with connected substations to be taken into account in the blocking logic. It can also transmit information about the position of all devices to the top-level automated control system.
The device constantly carries out self-diagnosis and signals when there is a malfunction, indicating the exact cause of the malfunction
DATA ACQUISITION AND CONTROL CABINET
SDU
Supervisory control unit provides display of information for operational personnel and manages operational locks according to the logic of locks.
SWITCHING DEVICES FOR NON-CONTACT POSITION DETERMINATION
KUBOP
Switching devices for contactless detection of the position of disconnectors of the KUBOP type are designed for switching low-voltage auxiliary circuits: signal, emergency, interlocking, control, and other secondary circuits.
