The Ministry of Railways spokesman Wang Yongping said that despite the multiple failures of the Beijing-Shanghai high-speed railway, the advanced and mature technology of the Beijing-Shanghai high-speed railway is undisputed. The main quality indicators of the project have reached the best domestic similar projects and the world's advanced level A set of safety precaution system including operation and maintenance, public security prevention and the impact of various disasters that may occur. According to reports, all high-speed rail systems are designed in accordance with the concept of "fault-oriented safety" and have very high safety and reliability. Because of this, no matter whether it is a link, a vehicle, a contact network, a communication signal, etc., any problem is detected at any point, the system will follow this design principle and take automatic and safe countermeasures. For example, Wang Yongping said that the CRH380 high-speed train used by the Beijing-Shanghai high-speed train has a very high degree of intelligence. There are more than 1,000 various detection sensors installed on the car, and there are only 210 temperature and speed sensors on the bogie. After the train detects the fault signal, it will immediately start the emergency response and automatically reduce the speed until it stops. Sometimes passengers smoking in the carriages in violation of regulations will cause train fire monitoring and alarm, resulting in stopovers. Such a highly reliable and sensitive security monitoring and guarantee system, although it will bring some impact to passenger travel, but can fundamentally avoid the occurrence of train accidents, can effectively protect passenger safety. Is the high-speed rail safe? In fact, during the initial operation of any equipment system, there will be relatively more failures. Everyone's high attention to the high-speed rail stems from the expectation of him. The new things are initially in a period of transition and transition, and should be understood. Other experts also said that the fault caused by the sensor has appeared on other lines before, and there is no guarantee that similar conditions will not occur in the Beijing-Shanghai high-speed rail line in the future. Understand the high-speed rail safety and intelligent technology from the level of enterprise technology application to protect the high-speed rail high-speed rail The road to economic development is always inevitable. The emergence of new policies will always be subject to many controversies. The birth of the new body will also need to go through a transition. There are many applications of electrical automation technology in the rail transportation industry. In order to learn more about the Beijing-Shanghai high-speed rail technology and its safety, and to enhance people's confidence in China's high-speed rail and support for major scientific and technological development projects, the following are selected. Interpretation by the technology provider of Shanghai High Speed ​​Rail. ABB traction transformer is used in CRH380BL high-speed EMU, one of the main models specially developed for Beijing-Shanghai high-speed rail. Its advantages of compact structure, high temperature resistance and strong mechanical impact resistance can effectively improve the energy use efficiency of EMUs. In the Beijing-Shanghai high-speed rail project, ABB's GIS gas insulated switchgear and circuit breakers are used in the power supply system of substations along the line to ensure a safe and stable power supply for locomotives and communication and signal systems. China Railway Electrification Bureau, as a system integrator in Beijing-Shanghai High-speed Railway, undertakes the design, construction, supply, testing, and inspection of the traction power supply system, power system, automatic remote monitoring and dispatching system (SCADA), disaster prevention system for the Beijing-Shanghai High-speed Railway. Joint commissioning and joint testing and equipment construction. China Railway Electrification Bureau has achieved a series of technological innovations in the design, product development, construction, inspection and testing of Beijing-Shanghai High-speed Railway. According to Wei Guo, general manager of the system integration electrification project department of the Beijing-Shanghai high-speed railway, the Beijing-Shanghai high-speed railway project uses all localized high-speed contact network spare parts products with independent intellectual property rights of more than 350 kilometers per hour, and two (Ministry of Railways) And the Ministry of Science and Technology) new products of the science and technology support plan, namely the anchor cable clamp for the cable end, the anchor cable clamp for the contact line terminal, the bend type locator, the anchor positioning clamp, the umbrella tooth ratchet anchor compensation device, etc. The products have reached the leading level of similar international products. CSR Zhuzhou Motor Co., Ltd. provided a total of 70 traction motors and 80 traction transformers for CHR380A EMUs, providing core traction power for Beijing-Shanghai high-speed rail. It is understood that the core traction power provided by CSR Zhudian is based on the technology of CRH2 type 200 km / h EMU traction motor and transformer, independently innovative design, and successfully developed CRH380A new generation EMU traction motor operating at 380 km / h. And transformers, the various indicators are comparable to the international advanced level, some key technical indicators are better than similar foreign products, with the advantages of low temperature rise, strong overload capacity, and restart after a long time running in hot state, long ramp start and operation The characteristics of high safety are more suitable for the operation of high-speed EMUs. In addition, the company deploys four high-standard and high-standard service stations in Beijing, Qingdao, Nanjing and Shanghai, and uses "zero failure" to ensure the safe, punctual and reliable operation of the Beijing-Shanghai high-speed rail.
