1.1 Application scenarios
Petrochemical industry:
Used for overload protection,stall protection,and phase imbalance protection of pump motors(such as crude oil delivery pumps and water injection pumps)to prevent motor burnout and production interruption.
Cooperate with ABB Ability™System 800xA DCS system to achieve linkage control with process flow(such as interlocking shutdown when pump fails).
Power industry:
Protect key auxiliary motors such as feedwater pumps,induced draft fans,and forced draft fans,and support multiple modes such as direct start,soft start,and variable frequency start.
In thermal power plants,communicate with the plant-level monitoring information system(SIS)through the Modbus TCP protocol to achieve remote monitoring of motor operation data.
Metallurgical industry:
Used for high-speed protection(rated speed>3000rpm)of blast furnace blowers and converter tilting motors,with a response time of<20ms to avoid mechanical damage.
Supports anti-electromagnetic interference design(compliant with IEC 61000-4-6 standard)and adapts to strong electromagnetic environments.
Cement industry:
Protect high-power motors(power>500kW)such as mill main motors and kiln tail exhaust fans,provide thermal overload inverse time protection to prevent motor windings from overheating.
Integrate with PLC system through PROFIBUS-DP protocol to realize automatic control of motor start and stop.
Municipal water supply:
Used for leakage protection,undervoltage protection,and overvoltage protection of water pump motors to ensure water supply safety.
Supports Chinese LCD display to facilitate operation by on-site operation and maintenance personnel.
1.2 Technical highlights
Multi-principle protection integration:
Integrate overload protection,stall protection,phase imbalance protection,leakage protection,undervoltage/overvoltage protection,ground fault protection,thermal overload protection,reverse power protection and other 10+protection functions to reduce the number of secondary devices and reduce wiring complexity.
High-precision measurement:
Current/voltage measurement accuracy≤±0.5%,power measurement accuracy≤±1%,meeting the needs of motor energy efficiency monitoring.
Fast action time:
Short-circuit protection action time<10ms(from fault occurrence to output tripping),far lower than the standard requirement of 20ms,effectively limiting the expansion of faults.
Adaptive protection logic:
Automatically adjust the protection setting according to the motor operating conditions(starting,running,no-load,load)to avoid false action/refusal to act.
