Problems solved by technology

However, most of the weight of the isolation transformer is borne by the bolts
In this way, during the operation of the rail vehicle, it is easy to cause the bolts to fail, thus making the isolation transformer less robust
[0003] Therefore, how to solve the problem of low firmness of the isolation transformer is a technical problem that those skilled in the art need to solve

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] The isolation transformer of the present invention is suitable for rail vehicles. Wherein, an auxiliary converter cabinet is provided under the rail vehicle. At least two load-bearing beams 3 are arranged side by side in the auxiliary converter cabinet. The isolation transformer includes an iron core 2 , a wire pack 1 wound on the iron core 2 , a clamp for fixing the wire pack 1 and the iron core 2 , and a jumper for lapping the isolation transformer on the load-bearing beam 3 . By arranging the isolation transformer on the load-bearing beam 3 , the weight to be borne by the fixture for fixing the isolation transformer can be reduced.

[0024] In one embodiment, such as figure 1 As shown, the bridging piece is the lifting lug 4 , which is overlapped on the load-bearing beam 3 . And the isolation transformer is located between the two load-bearing beams 3 . This ...

Abstract

The isolating transformer of the present invention is used in rail vehicles. Among other things, the rail vehicle includes an auxiliary converter cabinet provided with load-bearing beams. The isolation transformer consists of an iron core, a wire pack wound on the iron core so that both ends of the iron core are on the outside, a clamp for fixing the wire pack and the iron core, and a lap for attaching the isolation transformer to the load-bearing beam. Connectors, where the load beam carries the weight of the isolation transformer. In this way, the weight to be borne by the fixing piece for fixing the isolation transformer can be reduced, thereby effectively improving the fastness of the isolation transformer.

Description

technical field [0001] The invention relates to an isolating transformer for rail vehicles. Background technique [0002] An isolation transformer is a transformer with electrical isolation between the input winding and the output winding. Specifically, an isolation transformer is a safe power supply that can perform functions such as isolation, step-down, and filtering, and is widely used in power transmission and distribution of rail vehicles, high-rise buildings, airports, and tunnels. At present, when an isolation transformer is applied to a rail vehicle, the isolation transformer is generally fixed in an auxiliary converter cabinet of the rail vehicle by bolts. However, most of the weight of the isolation transformer is borne by the bolts. In this way, during the operation of the rail vehicle, it is easy to cause failure of the bolts, thereby making the isolation transformer less secure. [0003] Therefore, how to solve the problem of low robustness of the isolation ...
