The first batch of Yunnan-made supercapacitor + lithium titanate battery trams unveiled in Wenshan, Yunnan

On the morning of November 24, the first batch of modern trams processed by Kunming CRRC Rail Transit Equipment Co., Ltd. was unveiled at the Mina Depot in Wenshan Zhuang and Miao Autonomous Prefecture, Yunnan Province, and was officially delivered to the owners. Two trains of red trams with ethnic characteristic patterns and natural landscapes in Wenshan Prefecture are extremely festive and dazzling against the picturesque scenery along the way. They will soon serve the key construction projects of the 'Four Hundreds' in Yunnan Province. It has become an important part of the 'Ten' rail transit skeleton network in Qiubei County, Wenshan Prefecture, and welcomes Chinese and foreign guests. The car is composed of 4 modules, designed for a maximum operating speed of 70km/h, and a maximum capacity of 364 passengers. The first phase of line 4 (including branch lines) of the Wenshan Urban Rail Transit Modern Tram Demonstration Project in Wenshan Prefecture will become an important passenger flow connecting Puzhehei Scenic Area, Jiulong Valley Tourism Distribution Center, Qiubei County, Puzhehei Railway Station, etc. An important transportation line for the distribution point, with a total length of 21.107 kilometers, with 11 stations along the way. In order to deliver the vehicles smoothly, Kunming CRRC established a capable team, pooled high-quality resources, and with the strong support and help of Wenshan Puzhehei Tram Investment and Development Co., Ltd. and third-party supervisors, relying on CRRC's comprehensive development platform , A strong supply chain guarantee system overcomes the unfavorable factors brought about by the epidemic, fully promotes project implementation, and helps Yunnan prefectures to increase their economy. At present, CRRC Kunming has dispatched a group of employees to the Mina Depot in Wenshan Prefecture to start work and coordinate with the commissioning of trains to ensure the smooth operation of the vehicles. The world’s first hybrid power supply technology for supercapacitors and lithium titanate batteries. The vehicle design is based on the independent 100% low-floor modern tram platform of CRRC Kunming's head office-CRRC Zhuzhou Electric Locomotive Co., Ltd., using internationally leading and independently developed platforms Supercapacitor technology can be used to charge passengers within 30 seconds of getting on and off the car. At the same time, the entire line of contactless operation can be perfectly integrated with the urban landscape. The vehicle uses a hybrid power supply of super capacitors and lithium titanate batteries, which greatly improves the endurance and climbing ability, and adapts to the special line conditions of Wenshan area with many uphills, long slopes, and steep slopes. The first batch of modern trams made in Yunnan appeared in Wenshan's high-standard design. The vehicles are safe, reliable, lightweight and high-strength body. Lightweight and high-strength car bodies are used. Lightweight and high-strength stainless steel is used. . The four-dimensional independent braking system vehicle has braking modes such as normal braking, automatic emergency braking, emergency braking, and safe braking, which improves the safe operation ability of the vehicle in severe weather and emergencies. Dual-channel communication guarantee design The vehicle adopts dual-channel redundancy design. When a communication line fails, the system can automatically switch to another communication line to improve train safety and availability. The highest-level emergency avoidance configuration vehicles meet the highest fire protection standards required by international rail vehicles, and are equipped with movable side windows, fire extinguishers, fire hammers, emergency door handles and other safety facilities in the passenger compartment to ensure the safety of passengers. Taking a multi-pronged approach, the vehicle green energy-saving train adopts super capacitor energy storage technology, and preferentially adopts regenerative braking, and the energy regeneration rate is as high as 85%. Compared with the traditional tram power receiving method, it can reduce traction energy consumption by more than 30%. The passenger compartment uses high-voltage DC inverter air conditioners to improve passenger comfort and effectively save energy. The outer skin and side roof of the vehicle are made of light-weight, high-strength aramid honeycomb materials used in the aerospace field. The weight is reduced by 50% year-on-year, and operating energy consumption is reduced accordingly. The humanized design, the streamlined design of the front of the vehicle for comfortable ride, and the upward-looking headlights, like a smiling expression, greet visitors from all directions. The exterior decoration adopts local ethnic costume patterns and natural landscapes, reflecting the colorful and strong ethnic customs of Wenshan. The details are comfortable. 1. A full glass partition wall is used between the driver's cab and the passenger compartment, with LED light strips, and the whole car is transparent and bright. 2. The glass in the guest room is coated with frameless tempered glass, which effectively reduces ultraviolet radiation. 3. The entrance of the car door is less than one step above the ground, so passengers can get on and off the car quickly. 4. With a self-service door opening button, passengers can self-open the door during non-peak passenger flow periods. 5. Equipped with a dedicated wheelchair area, humanized care can be seen everywhere. The first batch of modern trams made in Yunnan appeared in Wenshan. Statement: Some pictures and content of the articles published on this site are from the Internet.
