Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a wiring structure for preventing bending and breakage in an oil-immersed transformer. Background Technology

[0002] Oil-immersed transformers are one of the important pieces of equipment in power supply and distribution systems for industrial and mining enterprises and civil buildings. They are transformer devices that use oil cooling to reduce transformer temperature and convert high voltage to a lower level suitable for transmission to homes and businesses.

[0003] Chinese Patent CN221884869U discloses an oil-immersed power transformer, specifically in the field of transformers. The transformer includes a main body with a transformer top fixedly connected to its top. An oil tank is connected to one side of the top of the transformer top, and terminals are embedded in the top of the top. This invention ensures stable installation of the transformer top and facilitates maintenance and repair. The oil tank holds transformer oil, providing insulation and, in conjunction with the cooling system, effectively reducing the transformer's operating temperature. The terminals connect the input and output circuits, ensuring stable power transmission. The combination of the cooling cavity plate and cooling windows provides a good cooling environment, while the built-in cooling fan enhances heat dissipation and reduces the risk of equipment failure. The guide plate optimizes the airflow direction, improving cooling efficiency. The combination of the base and grooved wheels facilitates transformer movement and enhances stability.

[0004] The above-mentioned scheme and existing technology of oil-immersed transformers usually complete the transformer wiring by tightening a copper wire lug with a cable connected to one end to the insulating terminal with a bolt. Since the cable needs to be bent for easier connection and fixation, this can easily cause the wiring to bend and break. Moreover, the firmly installed wiring is prone to bending and breaking when subjected to external impact. There is a lack of corresponding structure to prevent the wiring from bending and breaking, which needs to be improved and optimized. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The present invention proposes an anti-bending and anti-breakage structure for oil-immersed transformer wiring. This structure mainly involves fixing an inlet buffer connector and an outlet buffer connector to the inlet and outlet terminals respectively. The inlet and outlet copper wire lugs are connected to the inlet and outlet terminals respectively.
