Embodiment Construction

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] See attached figure 1 . In the electric locomotive auxiliary air source control system of this embodiment, the compressor A1 is an oil-free compressor, which is an air source generating device. This type of compressor can be put into operation for a long time, and the maintenance amount is small. Dryer A2 is a single-tower regenerative dr...

Abstract

The invention provides an auxiliary air source control system and an auxiliary air source control method for an electric locomotive. When the pressure of a channel 21 of a dryer A2 is lower than 4.8 bar, a relay KM1 is controlled to act to drive a compressor A1 to compress air; when the pressure in the dryer is up to 7.35 bar, the channel 21 and a channel 1 of the dryer A2 are disconnected, the channel 1 is closed, the channel 22 is communicated with channels 4 and 3, a regeneration air cylinder A3 discharges the steam into air through the channel 3 by a drying agent; when the pressure of the channel 4 is up to 2.7 bar, the compressor A1 is stopped. A micro computer, the dryer and a pressure switch control the compressor all together, thus the automatic starting and stopping of the compressor are achieved, and the automatic regeneration of the dryer is achieved at the same time. The control is more rational, and the intelligence of the electric locomotive is enhanced.

Description

technical field [0001] The invention relates to railway locomotive technology, in particular to an electric locomotive auxiliary wind source control system and method. Background technique [0002] In order to enable the electric locomotive to receive high voltage from the catenary, an auxiliary air source is installed on the locomotive to ensure that when the main air compressor of the locomotive cannot be put into operation, the auxiliary air source provides the necessary air source so that the electric locomotive can be lifted and received. Pantograph, close the main circuit breaker, etc., so as to complete the task of receiving voltage. At present, the auxiliary air source system of electric locomotive generally adopts oil-lubricated piston compressor, water separation filter and pressure switch as the main power and control components of the air source system. When the flight attendant presses the start button of the auxiliary compressor, the compressor starts to work....
