Description

Transformer Technical Field The embodiment of the application relates to the technical field of electrical engineering, in particular to a transformer. Background An oil immersed transformer is an electrical device widely applied to a power system, and core components of the oil immersed transformer comprise windings, an iron core, an oil tank and a radiator. The radiator generally comprises a plurality of radiating fins, the radiating fins are in heat exchange with air to radiate heat, the radiating fins are connected in series with the radiating pipes and are communicated to the inside of the oil tank, insulating oil flows through the radiating fins through the radiating pipes to conduct heat, a valve is arranged on the radiating pipes, the flow of oil in the transformer radiator is controlled through the valve, and the opening, closing and flow regulation of the radiator are achieved. The valve is installed between fin and oil tank, in order to ensure sufficient installation space in order to install the valve, can set up the connecting pipe of outwards extending in the outside of oil tank usually, this leads to the size increase of radiator, and then makes the overall size increase of transformer, need occupy bigger installation space. Disclosure of utility model Various embodiments of the present application provide a transformer, which is designed to provide a transformer having a smaller external dimension, thereby reducing the installation space. One embodiment of the present application provides a transformer, comprising: A box body, an installation part is arranged on the outer side of the box body, and The radiator comprises a radiating pipe, radiating fins and a valve, wherein the radiating pipe is communicated with the inside of the box body, the radiating fins are arranged on the radiating pipe, and the valve is arranged on the mounting part and is communicated with the radiating pipe. In an embodiment, the mounting portion includes a mounting plate and a stud, the mounting plate is disposed on the box, at least two studs are disposed on a side far away from the box, and the valve is mounted on the mounting plate through the studs. In an embodiment, the valve comprises a valve body and a butterfly plate, wherein the valve body is provided with a first oil passing hole, the butterfly plate is rotationally arranged on the first oil passing hole, the valve body is arranged in at least two mounting holes, and each stud penetrates through one mounting hole. In an embodiment, the end portion of the radiating pipe, which is close to the box body, is provided with a mounting flange, the mounting flange is provided with at least two flange holes, each flange hole and one mounting hole are coaxially arranged, and the stud sequentially penetrates through the mounting hole and the flange hole. In an embodiment, the mounting portion further includes at least two nuts, each of which is screwed to one of the studs and abuts against the mounting flange. In one embodiment, the mounting plate is welded to the housing, and/or The mounting plate is connected with the stud in a welding mode. In one embodiment, the plurality of radiating fins are uniformly spaced along the extending direction of the radiating pipe. In an embodiment, the transformer includes at least two radiating pipes, and the at least two radiating pipes are respectively communicated with two ends of each radiating fin. In one embodiment, each of the radiating fins is communicated with the radiating pipe. In an embodiment, the side wall of the box body is provided with an oil outlet, the mounting part is provided with a second oil passing hole, and the oil outlet and the second oil passing hole are coaxially arranged.
