QBJ-3WZ Speed Monitoring Emergency Trip Protection Device

The QBJ-3WZ emergency shutdown protection device serves as a critical safety component for steam turbine units, providing comprehensive monitoring throughout operation. During normal conditions, it continuously monitors turbine speed. In overspeed scenarios, the secondary emergency shutdown striker activates via centrifugal force, initiating an immediate turbine shutdown. The system employs three QBJ-CS-1 type sensors: one for speed measurement and two dedicated to emergency shutdown functions.

Sensor Screw Length	L60～200mm (customizable)

Primary Functions

Real-time display of current unit speed with emergency trip indication after striker deployment
Emergency stop functionality for immediate shutdown
Overspeed alarm system with configurable thresholds
Maximum turbine speed capture and recording
Block display function for operational status
Enhanced anti-interference capability for reliable operation

This protection device ensures operational safety and reliability for steam turbine systems through precise speed monitoring and rapid emergency response capabilities.
