The module serves as a specialized snubber component that targets voltage spikes generated during the switching process of IGBTs in the Mark V system. It suppresses these transient high-voltage signals in real time, reduces electrical stress on IGBTs, and prevents irreversible damage to these core power components, thereby extending the service life of the entire power control unit.
It is tailor-made for the Speedtronic Mark V gas and steam turbine control system. It fits perfectly with the system’s CMOS and VLSI chip – based design architecture and can be directly installed into the system’s standard card racks. It communicates and coordinates with other modules via the system’s internal bus without the need for additional modification or adapter components.
It is compatible with the Mark V system’s modular maintenance design. The control panel’s card racks can tilt outward, and the module connects via front – mounted ribbon cables that are easy to disconnect. This allows the module to be replaced while the turbine is running, minimizing downtime caused by maintenance and ensuring continuous operation of the turbine system.
It aligns with the Mark V system’s low – power design concept. Its circuit layout and component selection minimize power dissipation while maintaining efficient snubber performance. This not only reduces the overall energy consumption of the control panel but also avoids equipment overheating problems caused by high power consumption, ensuring stable operation of the system for long periods.
It is widely used in gas turbine control systems in power plants and industrial parks. It protects the IGBT components in the turbine’s power regulation unit. During the start – up, load adjustment, and shutdown processes of gas turbines, it suppresses voltage spikes from IGBT switching. It ensures the stable operation of the turbine’s ignition, fuel supply, and speed control systems, preventing sudden shutdowns or component damage due to IGBT failures.
In thermal power plants and combined heat and power projects, it is integrated into the Mark V control system of steam turbines. It works with the turbine’s pressure and temperature control modules. It protects the IGBTs responsible for adjusting steam valves and feedwater pumps. It ensures accurate and stable regulation of steam flow and pressure, which helps maintain the turbine’s power output stability and improves the efficiency of power generation.
It is applied to supporting power control systems of industrial turbines used in petrochemical and metallurgical industries. These turbines are often used to drive compressors, pumps, and other key equipment. The module protects the IGBTs in the turbine’s drive control circuit. It avoids equipment downtime caused by electrical component damage, ensuring the continuity of production processes such as raw material transportation and chemical reactions.
As a standard replacement part for the Mark V series, it is widely used in maintenance and retrofit projects of aging turbine control systems. Many industrial facilities with Mark V – equipped turbines rely on this module to replace worn or faulty snubber components. It restores the system’s IGBT protection capabilities and extends the service life of the entire turbine control system without the need for large – scale overhauls of the control system.
It is installed in the Mark V control systems of marine gas turbines. Marine environments have strict requirements for equipment stability and reliability. The module suppresses voltage spikes in IGBTs under conditions such as ship navigation vibrations and fluctuating power loads. It ensures the stable operation of marine gas turbines, which are critical for ship propulsion and on – board power supply, and enhances the safety and reliability of ship navigation.
