Railway station, Power World electrical solutions is power guarantee for railway station.
How to do with a sudden power failure? In addition to various infrastructure, fire fighting syestem, guiding system, security system, communication system, signal system, data system and so on are equiped with railway station. When the mains is failure, then the station can not work normally,the situation is quite serious.
Products requirements and challenge
The mainly function for generators of railway station is on maintenance and emergency. ATS functions, AMF functions, low noise, stable performance can support the normal running of railway station.
1. Low working noise
The generators make sure railway environment quiet enough for working. In the mean time, they also can make sure quiet environment for passengers.
2.Main and necessary protection device
The generators will auto start and send signal under following failures: low oil pressure, high temperature, overspeed, start failure and so on. Generator start mode should be auto. They must equip with AMF (automatic Mains Failure) functions and ATS, which realize auto start. When the mains is failure, the start time lags < 5s(adjustable), the generators can start automatically(there are three continuous auto start functions), mains/generator completely transfering time is < 10s. Thus, the generators can fully make sure the load time less than 15s. When the mains is on, the generators will maintain 0-300s running and then auto stop after cooling(adjustable).
3、Stable performance, strong reliability
Stable performance, MTBF is not less than 2000hrs;
Empty load volts of the generators is 95-105% of the rating voltage.
Solutions:
The generators, with advance performance, adopts low noise design, equip PLC-5220 control panel which is with AMF functions. Through connection with ATS, it makes sure the alternative power supply instantly when the mains is off.
Advantages:
Provide full set products and project, reducing the users' demands for products technology, which will be easier for generator running and maintenance.
The control system is with AMF function, which can auto start, with auto stop and alarm functions under various monitors.
ATS is optional; it can be inside the generators for small power.
Super silent. The noise level of power below 30kva is below 60dBA.
Stable performance, MTBF is not less than 2000hrs.
Compact dimension, some devices are optional for cold or high temperature areas.
Special design for special requirements of some customers.
