Embodiment Construction

[0016] The present invention will be further described through the layout of the air nozzles.

[0017] Air nozzle and layout plan one:

[0018] Single nozzle, i.e. one jet hole per nozzle (see image 3 ). This nozzle can achieve one-way fixed-point blowing. It can be used for the downwind air nozzle layout of high-speed EMUs. Round nozzles can be designed to deliver a straight air stream, or designed to deliver a swirling air stream. Rectangular nozzles can be designed to spray straight airflow at a certain height.

[0019] Air nozzle and layout plan two:

[0020] Dual nozzles, i.e. two jet holes per nozzle (see Figure 4 ). This nozzle can realize two-way fixed-point blowing. It can be used for oblique multi-angle blowing air nozzle layout for ordinary passenger and freight electric locomotives or low-speed working conditions of high-speed EMUs.

[0021] A sufficient safety distance must be maintained between the air jets and the high-voltage components of the roof p...

Abstract

The invention discloses a cleaning system for a top insulator of an electric locomotive. The cleaning system mainly comprises an air compressor, a vortex tube and a high-pressure hot air spray heads. By reasonably arranging the positions and quantity of the air spray heads, the surface temperature and dryness of the top insulator can be increased under the condition of not influencing the work and safety of a top high-voltage pantograph system, and water, ice, snow and dirt sticking to the top insulator are blown off to prevent the formation of pollution flashover conditions. Thus, the running reliability of the electric locomotive under a severe climate environmental condition is enhanced, economic losses of a railway transport system caused by various pollution flashover accidents are reduced, and the labor intensity of relevant operation and maintenance personnel is lowered.

Description

technical field [0001] The invention relates to the prevention and control of pollution flashover faults of insulators on the roof of electric locomotives in electrified railway transportation systems. Background technique [0002] With the increasing proportion of electrification in the railway transportation system and the increasing mileage of high-speed railways, environmental pollution and climate change have brought serious challenges to the safe operation of railways. Pollution flashover of roof insulators of electric locomotives is one of the common pantograph-catenary faults in electrified railways. These accidents not only caused various direct economic losses, but also disrupted the normal railway dispatching plan and affected passengers' confidence in railway services. [0003] In the past, ceramic insulators were mostly used on the roof of electric locomotives, because the surface is easy to accumulate dirt, and the operation and maintenance costs are high. Co...
