Abstract

The invention relates to an oil level alarm system for traction transformers and a control method for the alarm system, wherein, the oil level alarm system for traction transformers comprises an oil level indicator and a vehicular microcomputer control system, which is characterized in that an oil level upper limit alarm device and an oil level lower limit alarm device are arranged in the oil level indicator and are connected with the vehicular microcomputer control system. The invention provided for an electric locomotive or a motor train unit has the advantages of realizing the upper limit alarm and lower limit alarm of the oil level of the transaction transformers, meanwhile protecting the locomotive or the motor train unit via a vehicular control and protection circuit, further completing the monitor and protection of the transaction transformers system in the prior art and improving the running safety and reliability of the high-speed locomotive and motor train unit.

Description

technical field [0001] The invention relates to an oil level alarm system of a traction transformer of an electric locomotive or an EMU; the invention also relates to a control method for the oil level alarm system of the traction transformer of an electric locomotive or an EMU. Background technique [0002] At present, only an oil gauge with scale is installed on the auxiliary oil tank of the traction transformer of the electric locomotive or EMU. The oil gauge identifies the highest and lowest oil levels allowed. These location marks are only used as reference standards for refueling when the locomotive is stationary, and do not participate in the control and protection of locomotives or EMUs. Once the traction transformer oil has a large leakage or its oil level rises sharply for some reason, the oil gauge will not have any protective effect on the operation of the traction transformer and locomotive. [0003] The patent number is CN200520091479.0, and the name is "Bell...
