Electric locomotive and initiative air supplement system thereof

The utility model discloses an initiative air supplement system, including being used for setting up initiatively mending the wind fan, be used for sending the treater of setting for the rotational speed signal, the speed adjusting device who is used for initiatively mending the rotational speed of wind fan according to settlement rotational speed signal control according to locomotive operation signal and the real -time rotate speed condition of initiatively mending the wind fan in between machinery, wind fan signal connection treater is initiatively mended to speed adjusting device signal connection treater and initiatively mend the wind fan. This kind of initiative air supplement system can realize the regulation to the rotational speed of initiatively mending the wind fan through speed adjusting device's the setting and the control action of treater to can mend wind according to the actual demand between machinery, be favorable to guaranteeing maintaining the pressure -fired between machinery, and can red
