The professionalization of inverter functions has become a major trend in the development of today's transmission. The ACS510 series inverter is a product designed by ABB for fan and pump applications. The professional design ensures the stability of the product in the application process. In the application of station water supply, there are special requirements for the equipment installation environment and the special circumstances of the accident, and the handling of failures and preventive maintenance of the equipment are often important factors to ensure the safety of personnel in the event of an accident. The internal use of coated circuit boards in the ACS510 has greatly improved its adaptability to the environment. The accident mode of the station water supply application can ensure that the equipment continues to operate in the event of a fault to the greatest extent, and its own fault self-diagnosis function is a technical It provides a convenient path for personnel to analyze and deal with failures.        

Tianjin West Railway Station is the most modernized transportation hub in Tianjin. It covers an area of approximately 680,000 square meters. The main structure of the station building is 2 floors above ground and 3 floors underground. The total construction area is 180,000 square meters. The total scale of the parking lot is 24. line. It is closely connected with Tianjin Station through an underground diameter line; there are also long-distance passenger stations, two bus terminals and large parking lots in the station area, and more than 30 bus lines have stations in the West Railway Station. The West Railway Station has realized the "zero transfer" of multiple transportation modes such as railways, buses, subways, taxis, and long-distance passenger transportation, becoming the largest modern transportation hub in Tianjin. The new Tianjin West Station, along with Beijing South, Jinan West, Nanjing South, and Shanghai Hongqiao Station, has become the five major departure stations on the Beijing-Shanghai high-speed rail line, with the functions of departure and destination. System Configuration:        

Tianjin West Railway Station uses a total of more than 30 ABB standard inverters ACS510, with power levels ranging from 7.5 kW to 55 kW, which are mainly used in cooling pumps, refrigeration pumps, and drain pumps of central air conditioning systems. According to the actual operating conditions on site, the frequency usually runs between 40Hz-45Hz. Compared with the power frequency operation, there is about 20%-30% power saving potential.

solved problem:        

1. Adopt coated circuit board to make it more adaptable to humid installation environment;        

2. Automatically adjust the flow according to actual needs;        

3. Reduce the amount of manual maintenance;        

4. Frequency conversion speed regulation realizes soft start and soft stop, reducing mechanical shock and water hammer effect.
