Today, with the rapid development of high-speed rail in China, high-speed rail has become an important choice for people to travel because of its high speed, convenience and comfort. As the "power heart" of high-speed rail operation, the stability and reliability of high-speed rail traction power supply system are directly related to the safe and efficient operation of high-speed rail. During the operation of high-speed rail, the traction power supply system has to bear high load, large current and frequent current shocks, which puts forward almost harsh requirements for power supply equipment. Shanghai Fengchuang Industrial Co., Ltd. has developed a series of high-performance transformers by virtue of its profound technical accumulation and continuous innovation ability in the field of power equipment, which has built a reliable defense line for the stable operation of high-speed rail traction power supply system.

Since its establishment in 2010, Shanghai Fengchuang Industrial Co., Ltd. has been focusing on the research, development, production and sales of switching power supply, power filter and servo electronic transformer, and is a national high-tech enterprise. Over the years, the company has gathered top talents in the field of power electronics, set up a professional R&D team, constantly explored new technologies and new processes, and accumulated rich experience and excellent technical strength in the field of power equipment manufacturing. The company's "Fengyun-Fonyun" brand has won a good reputation in the market and the trust of many customers with its reliable product quality and excellent service. The transformer applied to the traction power supply system of high-speed rail this time is another outstanding achievement of Fengchuang's technical strength and innovative spirit.

The special transformer for high-speed rail traction power supply system developed by Fengchuang has achieved many breakthroughs in technology. In the design of iron core, the amorphous alloy material with high magnetic permeability is used, which has the characteristics of low hysteresis loss and high saturation magnetic induction intensity. Compared with the traditional silicon steel sheet iron core, it can reduce the no-load loss by 70%-80% and effectively reduce energy waste. The winding part is made of oxygen-free copper with high conductivity, and special winding process is used, which greatly reduces the winding resistance, reduces the load loss and improves the overall efficiency of the transformer. At the same time, in view of the frequent current surge in the traction power supply system of high-speed rail, Fengchuang transformer optimizes the insulation structure design, adopts high-strength and high-temperature resistant insulation materials and multiple insulation protection measures, which can withstand the impact of instantaneous high voltage and large current and ensure the safe and stable operation of the transformer under complex working conditions.

In terms of performance, Fengchuang Transformer is outstanding. It has high overload capacity, can bear loads several times more than the rated capacity in a short time, and meets the instantaneous high-power electricity demand of high-speed trains such as starting and accelerating. Advanced heat dissipation technologies, such as forced oil circulation air cooling and forced oil circulation air cooling, can quickly dissipate the heat generated during the operation of the transformer, and control the temperature of the transformer within a reasonable range even under long-term continuous high-load operation, thus ensuring the reliability and service life of the equipment. In addition, the transformer is equipped with an intelligent monitoring system, which can monitor key parameters such as voltage, current, temperature and oil level in real time, and transmit data to the control center through the communication interface to realize remote monitoring and fault early warning, so that the operation and maintenance personnel can find and deal with potential problems in time.

In practical application scenarios, Fengchuang transformer has shown strong support capability. On a busy high-speed railway line, the transformers used in the past are difficult to adapt to the working conditions of high load and frequent shocks, and the faults occur frequently, which seriously affects the punctuality rate and operation safety of trains. After the introduction of the special transformer for Fengchuang high-speed railway traction power supply system, the operation stability of the equipment has been greatly improved, and the number of failures has been reduced by more than 60%. The excellent overload capacity and stable voltage output of the transformer ensure the stability of power supply during the high-speed running of the train, effectively guarantee the stability and safety of the train operation, and improve the punctuality rate to over 99%, thus providing passengers with a better and more reliable travel experience.
