Railway and highway

Product requirements and challenges

The generator sets used on railways and highways are mainly used for mechanical repairs and emergency measures. ATS function, AMF function, low noise, stable performance, support the normal operation of railway station toll stations.

  1. Low working noise

Ultra-low noise, with a sufficiently quiet environment to ensure that railway personnel can dispatch with peace of mind, and also ensure that passengers can have a quiet waiting environment.

  1. Main and necessary protection devices

In the case of the following faults, the unit will automatically shut down and send out corresponding signals: low oil pressure, high water temperature, overspeed, unsuccessful start, etc.;

The unit start mode is selected as automatic start mode. The unit must have AMF (automatic mains failure) function and be equipped with ATS to achieve fully automatic start. When the city power is cut off, the start-up time delay is <5 seconds (adjustable), and the unit can be automatically started (a total of three consecutive automatic start functions), the city power/unit full load switching time is <10 seconds, and the time required to meet the input load is less than 12 seconds. After the city power is restored, the unit maintains 0-300 seconds of operation and automatically shuts down after cooling (adjustable).

  1. Stable performance and strong reliability

The average failure interval of the unit is not less than 2000 hours;

In terms of technical performance, the no-load voltage setting range of the unit is 95-105% of the rated voltage.

Solution

Generally, the toll station of the railway station consists of two power sources, one is the city power, and the other is equipped with some diesel generator sets to cope with sudden power outages. The generator set is required to have AMF function and ATS to ensure that once the main power supply of the railway station is cut off, the alternative power supply system must be able to provide power immediately, and the low noise and stability meet the special requirements of the railway station. By equipping with RS232 or RS485/422 communication interface, it can be connected with computer for remote monitoring, remote control, remote signaling and remote measurement, and fully automatic and unattended operation.

Advantages

A full set of products and solutions are provided to reduce the user’s technical requirements and make the use and maintenance of the unit easier;

The control system has AMF function, which can be automatically started, and has automatic shutdown and alarm functions under multiple monitoring;

ATS is optional, and the small unit can use the built-in ATS of the unit;

Ultra-low noise power generation to meet the needs of daily life;

Stable performance, the average failure interval of the unit is not less than 2000 hours;

The unit is small in size, and some devices can be optionally equipped to meet the operation requirements of cold and high temperature areas;

Customized design and development can be given for the special needs of some customers.
