Generator sets for railways and highways generally include mobile diesel generators and fixed diesel generators. Widely used in service areas and highway construction. According to functions: ordinary generator set, automatic generator set, monitoring generator set, automatic switching generator set and automatic parallel generator set. According to the structure: open frame generator set, box generator set and mobile generator set. Box-type generator set can be divided into: box-type rain-proof box generator set, low-noise generator set, ultra-quiet generator set and container power station. Mobile generator sets can be divided into trailer mobile diesel generator sets and vehicle-mounted mobile diesel generator sets.

 

product requirements and challenges

Generator sets used on railways and highways are mainly used for machine maintenance and emergency measures. ATS function, AMF function, low noise and stable performance support the normal operation of railway station toll station.

1, the working noise is low

Ultra-low noise, with enough quiet environment to ensure the safe dispatch of railway personnel, but also to ensure that passengers can have a quiet waiting environment.

2, the main and necessary protection device

Under the following conditions, the unit will automatically stop and send out corresponding signals: low oil pressure, high water temperature, overspeed, unsuccessful start, etc.

The starting mode of the unit is selected as automatic starting mode. The unit must have AMF (automatic mains failure) function and be equipped with ATS to realize full automatic starting. When the mains power fails, the starting time is delayed: After 5 seconds (adjustable), the unit can be started automatically (there are three consecutive automatic starting functions), and the full negative switching time of the mains/unit is ; 10 seconds, the time required to fully meet the input load is less than 12 seconds. After the commercial power is restored, the unit will stop automatically after maintaining 0-300 seconds of cooling (adjustable).

3, stable performance and strong reliability

The average time between failures 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 rated voltage.

 

solutions

Generally, railway station toll stations are composed of two power sources, one is the city power, and the other is equipped with some diesel generator sets to deal with sudden power failure. The generator set is required to have AMF function, equipped with ATS, and ensure that the alternative power supply system can provide power immediately once the main power supply of the railway station is cut off, with low noise and stability to meet the special requirements of the railway station. Equipped with RS232 or RS485/422 communication interface, it can be connected with a computer for remote monitoring, remote control, remote communication and telemetry, and it can be fully automatic and unattended.

 

advantages

Provide a complete set of products and solutions, reduce the user's requirements for mastering technology, and make the use and maintenance of the unit easier;

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

Optional ATS, small units can choose built-in ATS;

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

Stable performance, the average time between failures of the unit is not less than 2000 hours;

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

The special needs of some customers can be customized for design and development.

 

Operation specification of diesel generator set on expressway:

1. Operators must be familiar with the performance, structure and maintenance procedures of diesel engines and generators, and have skilled operation skills.

2. The generator set shall be placed stably, firmly fixed and well ventilated; When placed outdoors, cover should be erected, and sound insulation facilities should be set up when necessary.

3. Flammable and explosive articles shall not be placed near the generator set, and fire-fighting equipment shall be placed at the same time. If there is a fire, cut off the power immediately and stop the machine.

4. The cables from the generator to the distribution cabinet or to all electrical appliances shall be well insulated, and shall not be dragged and dropped on the ground casually, and the connectors shall be firmly connected.

5. Before starting the diesel engine, carefully check whether the cooling water and engine oil are sufficient; Whether the third filter cleans the channel; Check whether the pipe joint leaks oil or gas, and check whether the connecting parts are firm, whether the distributor and control system are normal, and whether the brush is stuck. And the air in the fuel system is removed.

6. When starting the diesel engine with the starter, the time shall not exceed 5 seconds at a time. The continuous starting interval shall not be less than 15 seconds. If it can't be started for three consecutive times, find out the reason before starting. Before starting the diesel engine equipped with electric heater, turn on the power supply, and then start the diesel engine after the electric heater heats up.

7. After the diesel engine is started, it should run at idle speed for 3-5 minutes, and carefully check the indications of various instruments of the diesel engine and whether there is abnormal sound on the machine. When the water temperature reaches 60℃, the diesel engine can be switched on to start the generator. When the diesel engine is running, the water temperature should be controlled between 60-80℃.

8. Before starting the generator, clean all parts, and check whether the carbon brush is fastened, whether the bolts are fastened, whether the display instruments are normal, whether the wire connectors are fastened, and whether the pressure regulating mechanism works reliably.

9, long-term stop generator before use, insulation inspection should be carried out. The insulation resistance must be greater than 1MΩ, and all institutions can be put into use only after being greased as required.

10, diesel engine running, the operator shall not be far away from the machine, should always check the instructions of the instrument; Whether the fuselage and bearings are noisy and overheated; Whether the diesel engine load is normal; Check whether the temperature rise of each rotating part is too high and whether the brush spark is too large. If there is any abnormal situation, stop the machine immediately for maintenance, and then work again after troubleshooting.

11, diesel engine running, it is forbidden to repair and cleaning work. All open gears, fans, belts and other parts should be equipped with protective devices.

12. When the generator is running, it is forbidden for anyone to work on the line or clean and maintain the machine.

13. Pay attention to whether the oil gauge, water temperature gauge, ammeter and other instruments are normal during operation, and do not carry out maintenance and adjustment work. Stop the machine in time to check if faults and anomalies are found.

14, the switchboard should be kept clean, the instrument should be checked regularly.

15, after the equipment maintenance, must check whether the machine tools and materials. Only after the inspection is correct can the test run be started.

16, every time after work, should do a good job of cleaning and maintenance of the machine.

17, after parking in winter, should pay attention to cold, antifreeze.

18, strictly implement the system of succession, fill in the operation log and maintenance records.

19, non-designated personnel shall not operate the diesel engine. No drunken operation.
