Haze not only affects the lives of the general public, but even begins to change the pattern of the locomotive manufacturing industry. The reporter learned from CNR yesterday that the first batch of 5 HXD3C freight electric locomotives produced by the company’s Dalian Machinery and Vehicle Company was delivered to the China Railway Corporation. Different from other railway locomotives, these locomotives have added anti-fog technology and devices, making them the first locomotives with anti-fog and haze functions in China.

Since last year, unprecedented haze weather has caused many problems for the normal operation of electric locomotives. Because the haze air contains a large amount of heavy metal particles and dust, it seriously affects the insulation performance of the high-voltage equipment on the top of the electric locomotive, which in turn affects the “end-of-end” operation of the locomotive, causing the operation of the railway locomotive to be affected and even leading to railways. Locomotive "armpit".

In order to solve the impact of haze weather on the locomotive, Dalian Engine and Transportation Company dispatched design engineers to track haze in the areas around Beijing, Tianjin and Hebei, and developed an “auto-changing function”. When encountering haze and other inclement weather, the driver did not lower the locomotive. The pantograph can complete the "end change" operation. After the pantograph is lowered, the contact with the haze can be easily conducted. When the "automatic changeover function" is added, the pantograph does not need to be lowered to effectively enhance the locomotive defense. The ability of bad weather," said CNR personnel.

An engineer said, “When the haze was not serious in previous years, after an electric locomotive had run to its destination, the staff could clean the dust by sweeping the roof with a sweeping wind band; but in recent years, the increasing haze has given rise to a lot of dust. Dust and other dirt are attached to the roof of the vehicle, affecting the on-off function of the locomotive. When the fog is severe, the electric locomotive needs to use cleaning agents to clean the high-pressure parts of the top cover of the locomotive every time it runs for 30 to 40 kilometers.

In order to effectively improve the anti-fog and anti-fog capabilities of locomotives, Dalian Engine and Vehicles Corporation has added an “automatic changeover function” to the development and manufacture of these locomotives. In the event of severe weather such as haze, the driver can not lower the locomotive pantograph. The end-of-end operation was completed, which effectively enhanced the ability of the locomotive to resist bad weather and improved the operating efficiency of the locomotive.
