The first high-power electric locomotive vehicle test bed debugging success
Latest discoveries and innovations
The first domestic high-power electric locomotive vehicle test bed, a few days ago in Wuhan Railway Bureau Wuhan high-power locomotive repair section debugging success, will be put into use in July. It can replace the harmonious high-power electric locomotive maintenance line operation test, save rail transit positive line occupancy time, reduce commissioning risk, to fill in the past on the locomotive test run must be on the line of the blank.
According to the person in charge of the repair section, the test rig is a complete vehicle test system developed by Wuhan High-power Locomotive Maintenance Section jointly with Beijing Railway Engineering Electromechanical Technology Research Institute. The maximum test load can reach 9,600 kW. The system can be used to simulate various test points in locomotive circuit trial operation in locomotive. The locomotive can find its dynamic fault without leaving home. So it is vividly called the locomotive "treadmill."
The test bench is mainly used for the traction power test and electric braking power test after the harmonic electric locomotive overhaul. It is composed of four parts of foundation pit device, electrical equipment area, noise reduction and ventilation device and central operation room. It adopts the leading domestic Electric power closed technology, locomotives and test benches form a mutual exchange network on the primary side of the catenary, which can feed back the energy consumption generated by the test back to the grid through feedback, greatly reducing the energy consumption of the test, using lifting rims and track control Electronic control wheelbase adjustment technology, can quickly complete the upper and lower test bench locomotive for HXD1B, HXD2, HXD2B, HXD3 and other 7 different wheelbase models test wheelbase rapid adjustment. The test bench to complete two times a day locomotive trial work, to meet the section with an annual output of 466 locomotives overhaul trial needs.
Ultra high strength heat treated anchor steel bar is a high performance steel that is inductively heat treated from hot rolled steel bars. It is widely used in anchoring, supporting, reinforcement and other projects in coal mine roadways, highway slopes, tunnels, dams, urban foundation pits etc. Pre-stressed concrete works, especially in coal mines.
This product not only has higher strength grade than ordinary hot rolled products, but also effectively reduces rock mass deformation, controls the surrounding rock damage range and has excellent impact resistance, which can resist sudden impact pressure and beneficial to ensure the safety of mining production.
This product has been approved by the Anbiao National Mine Product Safety Mark Center.
