Abstract

The invention relates to the field of transformers, in particular to a maintenance method of a high-speed railway vehicle-mounted isolation transformer. The transformer adopted in the method comprisesa transformer housing, a noise reduction mechanism, a vibration reduction mechanism, an insulation pad, a bottom plate, an adjusting mechanism, an auxiliary conveying mechanism, a first heat dissipation mechanism and a second heat dissipation mechanism. The bottom of the transformer housing is fixedly connected with two limit frames with a V-shaped structure, A surface plate is suspend by rotating that turntable when the turntable is need to be transported, extracting the slide plate to move the transformer housing, The sliding board is slid into the inside of the limit frame when being installed, and the rotary table is rotated counterclockwise to realize the upward movement of the pushing board in the inside of the fixing sleeve, so as to realize the suspension of the universal wheel, the ground plane is fixed with the ground plane, the support and fixation of the whole structure are realized, and the installation, the handling and the inspection and repair are convenient.

Description

technical field

[0001] The invention relates to the field of transformers, in particular to a maintenance method for a high-speed railway vehicle-mounted isolation transformer. Background technique

[0002] Isolation transformer refers to a transformer with electrical isolation between the input winding and the output winding. The isolation transformer is used to avoid accidental contact with the live body at the same time. The isolation of the transformer is to isolate the respective currents of the primary and secondary coils. In the early days, it was used in the electric power industry in European countries, and was widely used in the control power supply of general circuits in the electronics industry or industrial and mining enterprises, machine tools and mechanical equipment, as well as the power supply of safety lighting and indicator lights.

[0003] However, the traditional high-speed rail on-board isolation transformers are transported by cranes and trucks. Howeve...

Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] Such as figure 1 , figure 2 and Figure 4 As shown, a kind of high-speed rail on-board isolation transformer maintenance method described in the present invention, the method comprises the following steps:

[0028] S1, a pipe is installed on the side of the high-speed rail carriage; one end of the pipe communicates with the outside of the carriage, the other end of the pipe communicates with the interior of the carriage, and the end of the pipe in the carriage is located next to the high-speed rail on-board isolation transformer. When the high-speed rail is running, the negative The heat on the transformer is sucked out to achieve heat dissipation;

[0029] S2, installing a dust-proof net at the end of the pipeline in S1 to prevent dust...
