ALSTOM VCS232 Vacuum Contactor control and protection unit
Overview
ALSTOM VCS232 (full order No. 590.043158) is a dedicated intelligent control device in the VAMP series of ALSTOM (whose grid business has now been integrated into Hitachi Energy). Unlike the common feeder protection relays, the VCS232 is an integrated control and protection unit specifically designed for controlling and medium-voltage (typically 3.3kV to 12kV) Vacuum contactors.
Vacuum contactors are often used in situations with frequent operations and medium-level short-circuit currents, such as the starting and stopping of high-voltage motors, and the switching of transformers and capacitor banks. The VCS232 unit integrates traditional protection relays, control logic and interface circuits into a compact device, providing vacuum contactors with a complete, reliable and easy-to-apply “brain” and “guardian angel”.
Core features and advantages
1. Specialized protection function kit:
Advanced motor protection: It offers comprehensive protection for motors, including overcurrent, short circuit, ground fault, locked rotor, prolonged start-up, unbalanced load, underload (no-load), and thermal overload protection based on the I²t algorithm, which can simulate the thermal characteristics of the motor and prevent insulation damage.
Phase sequence protection: Detects incorrect phase sequence of the power supply to prevent the motor from running in reverse.
Under-voltage and over-voltage protection: Monitor abnormal power supply voltage to ensure that the equipment operates within the normal voltage range.
2. Powerful control and logic functions:
An output relay that directly provides control over the closing/opening coils of vacuum contactors.
It supports multiple motor control modes such as direct start, reversible start, and star-delta start, which are implemented through internal programmable logic without the need for complex external relay circuits.
◦ Built-in “Trip Circuit Supervision” protection and multiple closing lockout logic ensure operational safety.
3. Comprehensive measurement and diagnosis
High-precision measurement of all basic parameters: three-phase current, zero-sequence current (ground current), voltage, frequency, power, power factor, energy, etc.
VCS232-590.043158
Integrated fault recording and sequential event recording (SOE) capabilities with precise timestamps provide invaluable data for fault analysis and system debugging.
Monitor the wear of contactor contacts and the number of operations to provide predictive maintenance information.
4. Flexible communication and integration capabilities:
It comes standard with support for mainstream industrial communication protocols, such as Modbus RTU (via RS485 interface) and IEC 60870-5-103, and can be easily integrated into existing distributed control systems (DCS), PLCS or substation automation systems to achieve remote monitoring and control.
It provides rich programmable digital inputs and outputs for connecting local/remote buttons, status indicators, other interlock signals, etc.
5. Compact design and user-friendliness
It adopts a modular and compact design and can usually be directly installed on the switch cabinet door, saving space.
The front panel is equipped with a clear LCD display and navigation buttons, facilitating on-site data viewing, parameter setting and operation.
The graphical configuration through the dedicated VAMPSET software makes it very simple and intuitive to set protection parameters, control logic and display interfaces.
Typical application fields
VCS232 is specifically designed for medium-voltage equipment that requires frequent, reliable control and medium-level protection. It is mainly applied in:
• Industrial motor control: Start, stop and protection of high-voltage motors for large fans, water pumps, compressors, crushers, conveyor belts, etc.
• Power industry: Auxiliary control systems for power plants (such as coal mills, feed water pumps, and fans).
• Mining and cement industry: Control and protection of heavy equipment such as ball mills, crushers, and large fans.
Water treatment and Infrastructure: Control of high-pressure water pumps.
• Capacitor bank and transformer switching: It is used for the switching control and protection of reactive power compensation capacitor banks or transformers.
