Problems solved by technology
[0002] On electric locomotives, once the temperature in the electrical cabinet overheats, in order to prevent further fires, under normal circumstances, the power will be automatically turned off immediately; but because the electric locomotive is running at high speed, immediately turning off the power is equivalent to no Give the staff more time to react, which is prone to accidents; therefore, it can be seen that once a certain unit of the electrical cabinet is overheated, it can be used for emergency treatment without immediately turning off the power supply. a system structure

Embodiment Construction
[0045] The present invention will be further described below in conjunction with the accompanying drawings.
[0046] as attached Figures 1 to 15 The automatic electric control cabinet of the electric locomotive shown includes the electric locomotive control cabinet 50, and the middle part of the cabinet 42 of the electric locomotive control cabinet 50 is provided with a vertical air column 100, and the inside of the vertical air column 100 is a vertical directional gas channels; both sides of the vertical gas column 100 are distributed with a number of emergency cooling units 130 in an equidistant array along the vertical direction;
[0047] When the electric locomotive control cabinet 50 is working normally, each of the emergency cooling units 130 can absorb the hot air at its own location and flow it into the gas channel in the vertical air column 100;
[0048] When overheating occurs in the control cabinet 50 of the electric locomotive, each of the emergency cooling units...

The invention discloses an automatic electric control cabinet of an electric locomotive. The automatic electric control cabinet comprises an electric locomotive control cabinet, a vertical air column is arranged in the middle of a cabinet bin of the electric locomotive control cabinet, a vertical air channel is arranged in the vertical air column, and a plurality of emergency cooling units are distributed on the two sides of the vertical air column in the vertical direction at equal intervals in an array mode. According to the automatic electric control cabinet of the electric locomotive and working method of the invention, a suction and injection port sprays low-temperature carbon dioxide to an overheat electrical unit in a left-right periodic sweeping manner, so that the injected low-temperature carbon dioxide completely covers the overheat electrical unit instead of being only sprayed to the middle area of the overheat electrical unit, and therefore, the emergency cooling uniformity of the overheat electrical unit is enhanced.
Description
technical field [0001] The invention belongs to the field of electric locomotives. Background technique [0002] On electric locomotives, once the temperature in the electrical cabinet overheats, in order to prevent further fires, under normal circumstances, the power will be automatically turned off immediately; but because the electric locomotive is running at high speed, immediately turning off the power is equivalent to no Give the staff more time to react, which is prone to accidents; therefore, it can be seen that once a certain unit of the electrical cabinet is overheated, it can be used for emergency treatment without immediately turning off the power supply. A system structure. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an automatic electrical control cabinet and working method of an electric locomotive capable of emergency cooling [0004] Technical solution...
