Knowing this, Yang Jie was also stunned, he didn't expect Premier Zhu to take his opinion so seriously, and he almost couldn't wait to turn it into an express regulation and send it to the following.

"If the top management staff of these collective companies knew that this standard was your opinion, I think they would hate you for passing away. Vice Premier Song Xinyang said.

"Vice Premier Song, don't hurt me!" Yang Jie hurriedly clenched his fists and said.

"Haha, seeing that your Zhongyuan Automobile Company is expanding overseas, the center is also a kind of angry dissatisfaction with the state-owned automobile group company, and it's time to take out a whip and whip a few whips behind them. Vice Premier Song Xinyang said.

"I believe that by offering this standard, I think we will be able to make the domestic independent car brand to a new height in seven or eight years. Yang Jie said.

"Your company has now left behind all the people in fuel cell technology, the power pack supplied to the military has very good performance, the surface ships are now preparing to use your company's products, and the State Council is also preparing to apply your fuel cell technology to EMUs. ”

"Vice Premier Song, the Ministry of Railways is also preparing to design a new EMU?" asked Yang Jie.

"Yes, the Ministry of Railways has issued a new design task request, this design task by Jianning CSR Group Company, CSR Group previously designed and produced several types of electric locomotives, the previous production of electric locomotive power reached 3600 kilowatts, the maximum operating speed of 239 km / h request. ”

Song Xinyang said: "However, this speed is still not able to meet the transportation needs of domestic railways, and now the domestic railways are preparing to speed up, running high-speed EMUs with a speed of more than 250 kilometers per hour. Bombardier Canada, the production of high-speed train companies have been assessed, the electric locomotive technology standards produced by these companies are uneven, the blueprint is intended to introduce the Japanese traction system, the French electronic control system, the German driving control system, the Canadian track technology integration, but your company is now in the fuel cell and motor and control system is very good, but the fuel cell can be mounted on the high-speed electric vehicle, but to save the pantograph and high-voltage circuit of the exhibition, the Ministry of Railways is also preparing to develop its own new high-speed electric locomotive, your company can provide technical support。 ”

Yang Jie is also quite surprised, in the memory of the previous life, a few years later, the Minister of Railways Liu Daojun was full of courage to build a high-speed EMU with a speed of 350 kilometers per hour, and the method of exchanging skills from the Japanese Kawasaki Heavy Industries, Germany Siemens, France Alstom, Canada Bombardier and other companies that produce high-speed trains introduced their own skills to integrate, and developed their own high-speed rail skills after absorbing and digesting these system skills, and started the comprehensive construction of Huaxia high-speed EMUs.

What Yang Jie didn't expect was that this time, the Ministry of Railways changed its mind due to the breakthrough of its own company's fuel cell technology, and instead strengthened the motivation to carry fuel cell high-speed electric locomotives.

"Of course, our company will provide all kinds of technical support and services to CSR Group Company. Yang Jie nodded, Huaxing Group Company can enter the field of high-speed electric locomotives this time, of course, it is a very good opportunity.

A few days later, Yang Jie flew back to Tanzhou City and met with Han Shaoqi, chairman of CSR Group Company, and Zhang Shuguang, director of the Transportation Bureau and deputy chief engineer of the Ministry of Railways.

Han Shaoqi is full of white hair, but his eyes are bright, and he is full of anger when he speaks, this Director Zhang's eyes are sharp, and he looks very fierce.

After a cold greeting, Yang Jie also accompanied everyone to the conference room of the company's headquarters.

In the conference room, Peng Huqi, the director of the technical department of CSR Group Company, also introduced the Shaoshan Type 8 electric locomotive that CSR Group Company successfully developed and has been in service for a long time six years ago.

Shaoshan Type 8 is a four-axle quasi-high-speed trunk passenger electric locomotive developed on the basis of Shaoshan Type 5 electric locomotive.

The locomotive body adopts a frame-type all-steel welded structure, and the skin structure of the body is made of weathering steel, and the weight of the body is 18.1 tons. The overall arrangement is the traditional double-sided corridor of the electric locomotive, the driver's cab at both ends, and the whole car is divided into seven compartments, the transformer room in the middle, and the electrical room and mechanical room on both sides.

A high-speed pantograph is installed on the roof behind the driver's cab at both ends, which is a product of Siemens, and the roof equipment includes air circuit breaker, high-voltage current transformer, high-voltage inductance transformer, lightning arrester, etc.

Two bogies, two main air cylinders, air dryers and battery boxes are installed under the chassis of the car body. The locomotive adopts the natural ventilation method of the car body, and the cold air enters the car through the filter shutter of the locomotive side wall, and cools the traction motor, transformer and silicon rectifier unit through four air duct systems.

The braking system adopts an electronically controlled air brake, which is directly controlled by the locomotive electro-pneumatic brake to ensure the stability of the train during braking.

The continuous power of the locomotive is 3600 kilowatts, the maximum operating speed is 170 km/h, the total weight of the locomotive is 88 tons, and the axle load is 22 tons.

The 25,000 volt power frequency single-phase exchange current on the locomotive catenary wire is fed into the locomotive through the main circuit breaker by the pantograph, and then converted into direct current by the thyristor phased rectifier circuit after the traction winding is de-voltaged, and six traction motors are supplied in two groups in parallel, so that the traction motor generates torque, converts the electric energy into mechanical energy, and drives the wheelset through the transmission of gears.

The locomotive adopts an unequal three-stage half-controlled bridge phased rectifier circuit composed of high-power thyristors and diodes, which is produced by introducing high-power semiconductor manufacturing technology from Westinghouse Electric Company of the United States, but the technology is relatively backward.

Each locomotive is equipped with four DC traction motors, this type of motor is a six-pole series excited DC motor with a fully laminated welded frame mechanism and a compensation winding, with a rated power of 900 kilowatts, and the end grade is all H class, and the wheelset hollow shaft three-fulcrum elastic frame suspension is adopted, and the cooling method is forced air cooling.

The sponsorship circuit of Shaoshan 8 locomotive adopts a single-three-phase exchange system, the use of a rotary splitting camera to supply power to the sponsor circuit, converts the single-phase exchange power supplied by the sponsor winding of the main transformer into three-phase exchange power, and the ventilation cooling of various sponsored equipment in the car such as transformers, rectifier devices, traction motors, brake resistance cabinets and other devices, and the drive of the air compressor all use three-phase exchange motors, and the voltage suppression is 370 volts three-phase exchange electricity.

The locomotive is equipped with two complete sets of independent train power supply system, which is supplied with 870 volt single-phase exchange power by the main transformer power supply winding, and the output voltage is 600 volts direct current after rectification, with a power of 390 kilowatts.

The driver's cab of Shaoshan 8 locomotive adopts a microcomputer control system, which is composed of a microcomputer control cabinet, a display screen and a display control box installed on the driver's cab control platform.

The control system has the functions of constant current quasi-constant speed traction feature control, constant braking force control of braking system, anti-rotation and anti-skid control, magnetic field weakening control, air-electric combined braking control, train power supply control, fault diagnosis and fault recording.

The running part of the two-axle bogie locomotive of Shaoshan type 8 locomotive is two identical frame suspension two-axle bogies, the two prototypes initially still use the bogie similar to that of Shaoshan type 5 electric locomotive, using motor hollow shaft full suspension drive device, most of its gearbox is still unsprung weight, plus the wheel diameter is larger than 1250 mm, these two factors make the unsprung weight of the locomotive slightly larger, but due to the light axle load, it can still meet the wheel-rail interaction force index at the operating speed of 160 kilometers per hour, and later after reform, it was changed to adopt the wheelset hollow shaft six-link elastic transmission device, single-sided spur tooth six-link universal joint transmission, to meet the demand of 200 kilometers per hour, in addition to each bogie is equipped with a locomotive parking storage braking device, CSR group company has accumulated a lot of skills and experience for decades.

At this time, Peng Huqi took out the design drawings of the "Huaxia Star" high-speed train, "This is the high-speed train that our CSR Group Company participated in the trial production......"

"I'll interrupt," Yang Jie said at this time: "Since the Ministry of Railways and CSR Group Company have found our company, I also want to understand the real situation, how many skills of this Huaxia Star high-speed train are our own original innovation skills?"
