Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a transformer with an oil leakage prevention function. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. In electrical equipment and wireless circuits, transformers are commonly used for voltage step-up and step-down, impedance matching, and safety isolation. Transformers can be classified according to their uses, such as distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, and excitation transformers.

[0003] Oil-immersed transformers are prone to oil leakage or seepage during use. If the oil leakage is serious, it will affect the normal operation of the transformer. In order to avoid internal oil leakage, it is often necessary to reinforce the sealing strip assembly inside the transformer. A common protective structure is to install a box to collect the leaking oil at the bottom of the transformer equipment. However, due to the lack of a flow guiding structure, the leaked oil is easy to flow everywhere, which is inconvenient to collect and clean.

[0004] There is an urgent need for a transformer with oil leakage prevention function to solve the technical defects mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a transformer with an oil-proof function to solve the problem of inconvenient current collection mentioned in the background art.

[0007] As a further technical solution of this utility model, the bottom end of the support base is provided with an oil drain port, the guide groove is connected to the oil drain port, and the collection box is located below the oil drain port.

[0008] As a further technical solution of this utility model, mounting sliders are fixedly connected to both sides of the collection box, mounting slides are fixedly connected to the support legs, and a handle is installed at the front end of the collection box.

[0010] As a further technical solution of this utility model, the shock absorber is provided in four sets, the shock absorber is provided at both ends of the transformer housing, and the shock absorber is embedded inside the limiting cover.

[0011] As a further technical solution of this utility model, the connecting plate is installed on the transformer housing by bolts, and the top end of the shock-absorbing rod is connected to the bottom end of the connecting plate.

[0012] As a further technical solution of this utility model, both the first sealing strip and the second sealing strip are made of rubber.

[0013] As a further technical solution of this utility model, the first sealing strip is installed at the top and bottom of the transformer housing, and the second sealing strip is installed at the corner of the transformer housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the transformer with oil leakage prevention function not only realizes the functions of easy current conduction and collection, easy shock absorption and protection, but also realizes the function of enhanced sealing effect;

[0015] (1) By setting up a support base, collection box, handle, guide groove and oil drain hole, once the oil inside the transformer shell leaks out, the oil will drip from the oil drain hole at the bottom of the transformer shell into the guide groove of the support base. The oil can drip down the support base and be collected by the collection box. During maintenance, the maintenance personnel can take out the collection box to recycle and clean the oil inside. This structure achieves the effect of easy flow and avoids oil leaking everywhere and being inconvenient to clean.

[0016] (2) By setting up a damping plate, a limiting cover, a connecting plate and a damping rod, the transformer shell is installed on the damping plate. The damping plate has a certain damping and protection effect. During installation, the connecting plate is first installed on both sides of the transformer shell, and then the connecting plate and the damping rod are connected and installed. When using the transformer, the damping plate and the damping rod can improve the damping and protection effect and reduce the possibility of damage to the transformer shell. This structure realizes the function of easy damping and protection.

[0017] (3) By setting up a transformer housing, a first sealing strip and a second sealing strip, and installing multiple sets of first and second sealing strips inside the transformer housing between the pipe and the housing, the first and second sealing strips can reduce the oil inside the transformer housing from being exposed from the gap.
