The invention discloses an auxiliary transformer used for an electric locomotive. The auxiliary transformer comprises a transformer body and further comprises an oil tank for containing the transformer body, cooling oil for cooling is contained inside the oil tank, and cooling components are further arranged on the two sides of the oil tank. Connecting components are arranged on the outer side of the oil tank and used for being connected with a locomotive body and are steel channels. A junction box is further arranged on the outer side of the oil tank and used for outgoing of the auxiliary transformer used for the electric locomotive. A hydrophobic coating is arranged on the external surface of the junction box. An installing base for fixing the transformer body is arranged on the inner side wall of the oil tank. The transformer body is completely soaked into the cooling oil inside the oil tank. An oil injection opening is further formed in the top of the oil tank. An iron core of a reactor is arranged inside the transformer body of the auxiliary transformer used for the electric locomotive further comprises so that the auxiliary transformer used for the electric locomotive can have the functions of a transformer and the reactor. The auxiliary transformer used for the electric locomotive is convenient to install and capable of effectively solving the problem that an existing auxiliary transformer used for the electric locomotive is not waterproof and dustproof.
Description
technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to an auxiliary transformer for electric locomotives. Background technique [0002] With the rapid development of my country's economic construction, the market demand for various types of auxiliary transformers for electric locomotives is increasing. [0003] As an auxiliary transformer for electric locomotives, it is equipped with peripheral accessories such as cables and temperature sensors. Since it is hung at the lower part of the car body of the electric locomotive, the influence of rain, snow and dust must be considered. [0004] At present, auxiliary transformers are generally protected against water by dipping in paint as a whole after assembly. The above methods have high requirements for the process of dipping paint, and cannot fundamentally solve the problem of waterproof and dustproof. [0005] Therefore, how to solve the waterproof and dustproof of the...
