Switching electric cabinet SHAOT

controlpanelfloor-mounted

Transformers cooling control cabinets SHAOT are provided for automatic and manual control of ventilators motors, as well as electric pumps of transformers cooling systems according to IEC requirements and Customers individual requirements, including GOST 11677, NEMA requirements, as well as control cabinets with non-standard requirements regarding control algorithm, control commands and signals, signaling systems, design, arrangement, and installation of various service and information technology equipment. Control cabinets consist of standardized equipment set with control, protection, and measuring components, assembled on two levels. The level of switching devices and level of control and signaling components are separated from each other. That provides operation and maintenance safety. Control cabinets covering is metal construction with a front door and rotating panel inside the covering. Control cabinets can be equipped with a microprocessor monitoring and control system. A microprocessor control system is a substation monitoring system at the same time. The system allows the increasing lifetime of modernized transformers and significantly reduces costs for their repair due to timely detection of failures, arising while operating. Devices for diagnostics of moisture and gas content in transformer oil, oil and windings temperature indicators, as well as integrated monitoring and control systems, type Trafo Guard (oil level monitoring, windings and oil temperature, cooling system control), can be installed in the cabinets. Both relay algorithms execution solutions, and intelligent control systems on the basis of controllers can be applied in the cabinets.
