Product Details

1. The M-3425A digital generator comprehensive protection relay integrates essential main and backup protection functions for various generators, safeguarding the stable operation of the unit.
2. Configure conventional protections such as differential, reverse power, demagnetization, negative sequence overcurrent, stator grounding, and overexcitation to deal with various faults such as winding short circuits and load abnormalities.
3. Equipped with PT disconnection detection function, it automatically locks the protection action when there is an abnormality in the voltage circuit, preventing accidental tripping of the equipment in a fault free state.
4. Built in fault recording and event recording functions, saving various electrical data at the moment of tripping, allowing for quick troubleshooting of fault causes during maintenance.
5. The body comes with an operation display screen and buttons, allowing users to view operational data and set protection settings on site without the need for external devices.
6. The sampling circuit should be electrically isolated to resist on-site electromagnetic interference, and the protection program should not malfunction during the switching process of high-voltage equipment.
7. Support access to communication systems, upload operational status and alarm information to the central monitoring platform, and achieve remote online monitoring.
8. The terminals are firmly fastened, and the wiring is not easy to loosen under long-term vibration environment of the unit, ensuring stable connection between the sampling circuit and the trip circuit.
9. Strong adaptability to wide temperature range, the control room works continuously throughout the year, and the measurement and protection accuracy will not deviate significantly in high and low temperature environments.
10. Equipped with frequency anomaly protection and low-frequency load shedding related logic, timely execution of corresponding control strategies when the grid frequency deviates from normal values.
11. The enclosed structure of the shell does not require a cooling fan, making it less prone to dust accumulation and requiring less daily maintenance and cleaning work.
12. Standard cabinet installation specifications can be directly replaced in situ on site, without the need for significant modifications to the original secondary wiring.
13. Automatically complete the hardware self-test of the entire machine when powered on, check for any abnormalities in the sampling channel and output contacts, and proactively avoid potential hazards.
14. Expandable multi-channel switch input and output contacts are used to link circuit breaker tripping, on-site sound and light alarms, and unit interlocking actions.
15. M-3425A is commonly used for protection renovation and replacement of faulty spare parts in thermal and self owned power plant generators.
Summary: This protective relay has complete protection functions and stable operation, and is the core supporting equipment for the safety protection of generator sets.
