Abstract

The invention provides an information warning circuit for a main transformer of an electric locomotive. The information warning circuit comprises an oil temperature information warning module which is arranged on an operating bench of the electric locomotive, connected with a temperature sensor and used for supplying oil temperature warning information according to temperature information of an oil tank of the electric locomotive detected by the temperature sensor; and an oil blast information warning module which is arranged on the operating bench of the electric locomotive, connected with apressure release valve and used for supplying oil blast warning information according to temperature information of the oil tank of the electric locomotive detected by the pressure release valve. Dueto the technical scheme of the invention, by arranging the warning modules on the operating bench, the oil temperature or pressure information of the main transformer is provided; when the electric locomotive stops the operation, the driver can understand whether the operating stoppage of the locomotive is caused due to too high oil temperature or too high pressure of the main transformer in time; and if so, the corresponding measure can be adopted in time, and the fault reason is processed, so that the enlargement of the fault caused thereby the reason is prevented.

Description

technical field [0001] The invention relates to the field of electric locomotive manufacturing, in particular to an information warning circuit for a main transformer of an electric locomotive. Background technique [0002] During the operation of the electric locomotive, the oil temperature of the main transformer will rise. When the oil temperature of the main transformer rises to a certain level, the pressure in the oil tank will rise sharply, causing the main transformer to deform or even burst, which will cause the locomotive failure. . In order to solve this problem, in the prior art, a temperature sensor is installed on the main transformer to detect the temperature of the oil tank in real time. At the same time, a pressure release valve is installed on the upper oil tank, the lower oil tank and the oil storage tank of the main transformer to detect the pressure in the oil tank, and through the oil The temperature control circuit is connected with the main circuit br...
