Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer lead fixing structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The top of the transformer usually has high-voltage and low-voltage bushings to protect the leads. However, if the extended leads are not fixed, the layout will be chaotic. Once the transformer encounters a collision, the cable is likely to be damaged. Therefore, it is particularly important to fix the transformer leads.

[0003] Existing, such as Chinese patent publication number CN210467465U discloses a transformer lead fixing structure, which includes a bottom plate, the left and right ends of the top of the bottom plate are fixedly connected with support frames, the top between the two opposite sides of the support frames is fixedly connected with a cross bar, the bottom of the cross bar is fixedly connected with three pulley assemblies, the left and right ends of the top of the bottom plate are movably connected with mounting brackets through bolts, the opposite sides of the two mounting brackets are fixedly connected with a reinforcing rod, the top of the mounting bracket is fixedly connected with a transformer body, and the outer surface of the transformer body is fixedly connected with a heat sink. The transformer lead fixing structure achieves the purpose of stably fixing the lead body by rotating the threaded rod, which is convenient for the staff to fix the lead body, and the fixed connection is stable, which will not affect the use of the transformer body, while improving the utilization rate of the device, facilitating use and installation, and suitable for various situations.

[0004] Although the above patent achieves multi-spot welding to facilitate the staff to fix the lead body, and the fixed connection is stable and will not affect the use of the transformer body, while improving the utilization rate of the device, facilitating use and installation, and being suitable for various situations, there are still some shortcomings. For example, when the transformer is generally installed, the lead is fixed after the transformer is installed, and the crossbar and the support frame of the device are large in size. At the same time, the transformer is usually installed in the middle of the electric pole, at a certain distance from the ground. In this way, when the staff installs and fixes the transformer, the support frame and the crossbar will be particularly troublesome, which increases the danger of the staff installing and fixing the transformer. Therefore, it is necessary to propose a new type of transformer lead fixing structure. Utility Model Content
