Description

ABB  5SHX2645L00064  High-Voltage Device Module

• High rated current support: With a rated current of 2645 amperes, it can stably carry large current loads, meeting the high-current transmission requirements of high-voltage cables in power systems (such as cable connections in substations and power supply circuits of large-scale power equipment). It ensures no performance degradation caused by current overload under full-load conditions.
• Compatibility with high-voltage scenarios: Although the rated voltage is not directly specified, it can be inferred from its positioning of “being used for connection and protection of high-voltage cables” that it has a high voltage withstand capacity. It can adapt to the working environment of high-voltage cables (usually medium and high voltage levels, such as 10kV and above) in power systems and meet the insulation and voltage withstand requirements of high-voltage circuits.

• Efficient on-off control: As a component for connecting and disconnecting high-voltage cables, it has fast and reliable on-off capabilities. It can flexibly control the connection and disconnection of high-voltage cable circuits, meeting the needs of rapid switching in scenarios such as power system switching operations and equipment maintenance, and reducing operation time and the impact of circuit interruptions.
• Comprehensive fault protection: Specifically designed for cable protection, it can accurately detect and respond to overload and short-circuit faults:
  • When the cable is overloaded (current exceeds the safe threshold), it can cut off the circuit in time to prevent the cable from insulation aging or burning due to long-term overcurrent heating;
  • In case of a short-circuit fault (such as short-circuit current caused by cable insulation breakdown), it can act quickly to cut off the circuit, limit the impact of short-circuit current on cables, substation equipment and the power grid, reduce the risk of fault spread, and protect the safe and stable operation of the power system.

• Industrial-grade durability: Adopting ABB’s mature packaging technology for high-voltage devices and weather-resistant materials, it has excellent anti-interference ability (such as withstanding electromagnetic interference and surge voltage in power systems) and mechanical strength. It can adapt to complex industrial environments such as substations and outdoor cable trenches (temperature fluctuations, dust, vibration, etc.) and ensure long-term stable operation.
• Low maintenance requirements: The design focuses on long service life and maintenance-free characteristics, reducing the number of power outages for maintenance caused by module failures, lowering the operation and maintenance costs of the power system, and improving the overall operation efficiency.

• Strong system integration: It can seamlessly integrate into the protection and control circuits of power systems (such as linkage with relay protection devices), realizing automatic collaboration of fault detection, signal feedback and action execution, and improving the intelligent protection level of power systems.
• Ensuring power grid stability: Through reliable protection of high-voltage cables, it reduces power grid fluctuations or power outages caused by cable faults, indirectly ensuring the continuity and stability of power supply in the power system, and plays an important supporting role in key scenarios such as industrial production and residential electricity consumption.
