New DC switchgear concept
Our own vision of DC switchgear allowed PLUTON experts to create a conceptually new design characterized by compact size, maintainability, operational reliability and personnel safety.
Specific features:
•application of arc-free ultra high-speed DC circuit breaker with innovative principle of power circuit opening in vacuum allows using half the size of work space in comparison with standard circuit breaker;
•uni- or bilateral maintenance, as well as free access to units and components, located in the upper part of the device;
•built-in microprocessor traction network monitoring and protection system SMTN-3;
•well-thought-out ventilation system and IP 33 protection level provide well-balanced thermal operation mode.
compact design
lowest maintenance and high reliability
maintainability and operational safety
compliance with international and European standards
Additional benefits:
•high assurance of personnel safety due to electromechanical interlockings and protections;
•intelligent control, protection and diagnostics system;
•compliance with EN 50123-1/IEC 61992-1, EN 50123-6/IEC 60992-6 international standards.
AFB arc-free ultra high-speed circuit breaker with improved operational characteristics is applied in DC switchgear:
•no open arc;
•lowest maintenance;
•high wear resistance and long lifetime;
•high-speed contacts opening system;
•minimum tripping time;
•equipped with control and internal monitoring system;
•protection functions: Imax protection and di/dt protection.
