Description
Technical Field
The invention relates to the technical field of high-voltage boxes of electric locomotives, in particular to a high-voltage box for an electric locomotive, which is suitable for a high altitude environment.
Background
Plateau railways are used more worldwide. The typical plateau railway in China is the Qinghai-Tibet railway, the section with the altitude of more than 4000 meters accounts for about 85% of the whole line, the highest altitude is 5072 meters, and the plateau railway is the highest altitude, the longest distance, the most complex geographic condition and the most severe operating condition in the world. Along with the increase of the altitude, the air pressure is gradually reduced, the ionization process in the air is enhanced, and further the external insulation strength of the high-voltage component of the electric locomotive is reduced, so the insulation performance requirement of the high-voltage system of the electric locomotive running in a high-altitude area is stricter. At present, locomotives operated in high altitude areas in China are mainly diesel locomotives, and electric locomotives are rarely applied. At present, domestic electric locomotives have operating experience only below the altitude of 4000 meters. The electric locomotive technical platform and the corresponding standard system applied in the plateau are still in the exploration stage. According to the development and planning of the national railways on the northwest plateau railways, along with the acceleration of foot steps in the electrified transformation and construction of the Qinghai-Tibet railway, the development of the plateau alternating-current transmission electric locomotive suitable for the plateau environment is urgent. The high-voltage system is especially important as a system which changes the most aiming at the plateau environment and carries out system-in-depth research and experimental verification on the system.

The high-voltage electrical box for the top of the electric locomotive solves the problems that the high-voltage electrical equipment at the top of the existing locomotive is not standby, and the roof distributed single electrical equipment has large maintenance workload and is easily influenced by environmental factors to cause pollution flashover; meanwhile, the interior of the railway vehicle adopts a double-main-break natural isolation redundancy design, and when a fault occurs, the double-main-break natural isolation redundancy design can be mutually replaced to work, so that the safety of a fault electric appliance and the safety operation of the railway vehicle are ensured.
The main influence of high altitude on the insulation strength of high-voltage equipment is air density, the higher the altitude is, the lower the air pressure is, the air ionization process is enhanced, the air dielectric strength is weakened, further the external insulation strength of the high-voltage equipment is reduced, the external insulation strength of the high-voltage equipment can be enhanced by modifying according to the corresponding altitude, the electrical clearance and creepage distance are increased, the volume and weight of the high-voltage equipment are increased, the distance between the high-voltage equipment and the ground is increased, further the volume of a net side cabinet body arranged between the machines is increased, no redundant space is provided for increasing the net side cabinet between the electric locomotive machines at present, in addition, the high-voltage equipment in the high-voltage box is horizontally arranged, the cantilever of each equipment is already large, if the scheme is adopted under the environment of 5100 m altitude, the weight increment and the large cantilever of each equipment can affect the strength and the safety stability of the high-voltage box, the feasibility is poor.
