Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated transformer substations, in particular to a box transformer with an accident oil pool. Background Art

[0002] The box transformer is also called a prefabricated substation or a combined transformer. For oil-immersed transformers, when the oil weight of the transformer reaches a certain weight, the installation site of the transformer is required to be equipped with an emergency oil pool. For oil-immersed transformers installed indoors, a pit is usually dug under the transformer as an emergency oil pool; for oil-immersed transformers installed outdoors, there are two ways to install the emergency oil pool: one is to install it near the box transformer, and make another oil tank near the box transformer as an emergency oil pool. This method is more troublesome during transportation and on-site installation; the other is to seal the base of the box transformer as an emergency oil pool, but because the base welding and sealing process are more complicated, this method is prone to water ingress and oil leakage. Utility Model Content

[0003] In view of the defects of the above-mentioned prior art, the purpose of the utility model is to provide a box transformer with an emergency oil pool to solve the installation problem of the emergency oil pool of the oil-immersed transformer.

[0004] The purpose of the utility model is achieved by the following technical solutions:

[0005] A box transformer with an emergency oil pool comprises an oil-immersed transformer, a high-voltage chamber and a low-voltage chamber. The bottom of the oil-immersed transformer is provided with an emergency oil pool, and the bottom of the oil-immersed transformer is the top sealing surface of the emergency oil pool.

[0006] Furthermore, the side wall panels of the high-pressure chamber and / or the low-pressure chamber are side sealing surfaces of the accident oil pool.

[0007] Furthermore, an oil tank is provided in the oil-immersed transformer, and the oil tank is arranged directly above the emergency oil pool.

[0008] Furthermore, a connecting pipe is fixed between the oil tank and the emergency oil pool.

[0009] Furthermore, a valve is provided on the communicating pipe.

[0010] Furthermore, the high-pressure chamber, the low-pressure chamber and the accident oil pool are all fixed on the same base.

[0011] The beneficial effects of the utility model are:

[0012] The utility model arranges the accident oil pool at the bottom of the oil-immersed transformer, which not only facilitates the connection between the oil tank of the oil-immersed transformer and the accident oil pool, but also avoids the installation or leakage problems caused by making an additional accident oil pool near the box transformer or sealing the box transformer base as the accident oil pool, and is suitable for indoor or outdoor installation.

[0017] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clearly understood, the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown, the utility model provides a box transformer with an emergency oil pool, comprising an oil-immersed transformer 1, a high-voltage chamber 2 and a low-voltage chamber 3. An emergency oil pool 4 is arranged at the bottom of the oil-immersed transformer 1. The high-voltage chamber 2, the low-voltage chamber 3 and the emergency oil pool 4 are all fixedly arranged on the same base 5. The emergency oil pool 4 is arranged between the oil-immersed transformer 1 and the base 5.

[0019] For the box transformer, as one of the preferred solutions, the high-voltage chamber 2 and the low-voltage chamber 3 are located on the same side of the oil-immersed transformer 1, and when viewed from above, the oil-immersed transformer 1, the high-voltage chamber 2 and the low-voltage chamber 3 are in a herringbone shape; as a second preferred solution, the high-voltage chamber 2 and the low-voltage chamber 3 are located on both sides of the oil-immersed transformer 1, and when viewed from above, the oil-immersed transformer 1, the high-voltage chamber 2 and the low-voltage chamber 3 are in a herringbone shape.

[0020] The accident oil pool 4 is arranged at the bottom of the oil-immersed transformer 1, which not only facilitates the connection between the oil tank 8 of the oil-immersed transformer 1 and the accident oil pool 4, but also avoids the troublesome problems of installation or manufacturing caused by making an additional accident oil pool 4 near the box transformer or sealing the box transformer base 5 to make the accident oil pool 4.

[0021] The sealing wall of the emergency oil pool 4 can be provided separately or in the following manner.

[0022] The accident oil pool 4 is arranged at the bottom of the oil-immersed transformer 1, that is, under the box bottom 6 of the oil-immersed transformer 1, so that the box bottom 6 of the oil-immersed transformer 1 can be used as the top sealing surface of the accident oil pool 4, which not only simplifies the manufacturing process of the accident oil pool 4, but also reduces the cost of the accident oil pool 4.

[0023] The side wall panel 7 of the high pressure chamber 2 and / or the low pressure chamber 3 is used as a sealing surface on one side of the accident oil pool 4, so as to further reduce the manufacturing cost of the accident oil pool 4.

[0024] When manufacturing the base 5 , a boss is designed at the position of the base 5 corresponding to the accident oil pool 4 , so that the top wall of the base 5 can be used as the bottom sealing surface of the accident oil pool 4 , thereby simplifying the manufacturing process of the accident oil pool 4 .

[0025] In addition, the other side wall sealing surfaces of the accident oil pool 4 can be installed by extending the side wall of the oil tank 8, that is, the accident oil pool 4 and the oil tank 8 can share the same side wall.

[0026] An oil tank 8 is provided in the oil-immersed transformer 1 . The oil tank 8 is provided just above the emergency oil pool 4 . A connecting pipe 9 is fixed between the oil tank 8 and the emergency oil pool 4 . A valve 10 is provided on the connecting pipe 9 .

[0027] Specifically, one end of the connecting pipe 9 is connected to the bottom of the oil tank 8, and the other end is connected to the top of the accident oil pool 4. When the oil in the oil tank 8 needs to be put into the accident oil pool 4, the valve 10 is opened and the oil in the oil tank 8 will flow into the accident oil pool 4.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
