Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and in particular relates to a high-strength and ultra-thick transformer conical support. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is mainly composed of a primary coil, a secondary coil, and an iron core (magnetic core). When an AC current flows through the primary coil, an AC magnetic flux is generated in the iron core (or magnetic core), inducing a voltage (or current) in the secondary coil. Transformers are usually used in the power generation, transmission, and distribution of power systems. In the power generation stage, a high-voltage transformer increases the voltage generated by the generator to reduce line losses during the transmission process. In the transmission stage, a high-voltage transformer transmits electrical energy from a power station to distant users. In the distribution stage, a high-voltage transformer reduces electrical energy from high voltage to a low voltage suitable for users.

[0003] The transformer outlet device is an important part of the transformer, which is mainly responsible for leading the electric energy inside the transformer and transmitting it to the external circuit. It is usually composed of outlet bushings, outlet conductive rods, outlet insulators and other components. Among them, the outlet bushing is one of the key components of the transformer outlet device, which is responsible for leading the electric energy inside the transformer and connecting it to the external circuit. The outlet conductive rod is another important component of the transformer outlet device, which is responsible for transmitting the electric energy from the outlet bushing to the external circuit. The outlet insulator is used to support the outlet conductive rod and maintain the insulation distance between it and the transformer body.

[0004] The main component used to connect the transformer outlet device to the riser is the supporting structure. The vibration generated by the long-term operation of the outlet device poses a challenge to the strength of the supporting structure. When the weight of the outlet device is relatively large, the support structure is often wrapped with cardboard to enhance the strength. However, such a combination of multiple components is not only cumbersome to process, but also not stable enough in structure. Therefore, it is necessary to improve the supporting structure of the transformer. Utility Model Content

[0023] The present invention provides an integrated and high-strength ultra-thick transformer conical support member, the structure of which enables it to bear a transformer outlet device of relatively large weight.

[0024] The transformer conical support member of the present application is described in detail through the following embodiments.

[0025] Embodiment 1:

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, a high-strength and ultra-thick transformer conical support member includes a support member body, which is a conical structure made of cardboard. Specifically, a mold of the support member is first made, and then thin paper blanks are stacked one by one along the radial direction of the mold, and the paper blanks are continuously pressed until the thickness of the support member body reaches the design requirement.

[0027] The support body is divided into an upper port annular portion 100 , a conical support portion 200 in the middle, and a lower port annular portion 300 , which are connected in sequence; wherein the inner diameter of the upper port annular portion 100 is smaller than the inner diameter of the lower port annular portion 300 .

[0028] In the present technical scheme, as a support member used for the transformer, its insulation performance is the most important, and then the compressive resistance of the support member is considered. The traditional transformer support member is a square bracket. When it is made of cardboard, not only is the production cycle long, but its structure is not stable enough and its bearing capacity is relatively weak. For this reason, the support member is designed to be a conical structure, which not only improves the overall strength of the support member, but also has strong stability when supporting the transformer outlet device.

[0029] In the present embodiment, the upper port annular portion 100 is optimized to be provided with an opening 110, and the opening 110 extends from the end of the upper port annular portion 100 to the conical support portion 200; wherein, there are multiple openings 110, and they are distributed along the circumferential direction of the upper port annular portion.

[0030] A window 210 is formed on the outer wall of the conical support portion 200 . There are a plurality of windows 210 , which are distributed along the circumferential direction of the outer wall of the conical support portion 200 .

[0031] A circular hole 310 is opened on the side wall of the lower port annular portion 300 . There are a plurality of circular holes 310 , which are distributed along the circumferential direction of the side wall of the lower port annular portion 300 .

[0032] In the present technical solution, the upper port annular portion 100 faces upward, the lower opening 110 of the annular portion faces downward, the support body is sleeved on the insulating sleeve of the transformer outlet device, and the lower opening 110 of the annular portion is connected to the lifting seat. Specifically, the connection is achieved through a circular hole 310 opened on the side wall of the lower port annular portion 300. Opening the opening 110 on the upper port annular portion 100 is convenient for installation so that it can be in close contact with the insulating sleeve. Opening the window 210 on the outer wall of the conical support portion 200 plays a role in reducing its own weight. Specifically, the window 210 is an elliptical opening, which can ensure the support strength.

[0033] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
