[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 electrical control cabinet for an electric locomotive, which includes a control cabinet for the electric locomotive. A vertical air column is arranged in the middle of the cabinet of the electric locomotive control cabinet, and the inside of the vertical air column is vertical. Gas channel; both sides of the vertical air column are equidistantly distributed along the vertical direction with a number of emergency cooling units; the suction and injection outlets of the present invention are sprayed to the overheated electrical unit in the form of periodic sweeping from left to right, so that the injection The low-temperature carbon dioxide fully covers the overheated electrical unit, instead of spraying only to the central area of the overheated electrical unit; thereby enhancing the emergency cooling uniformity of the overheated electrical unit.
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...
