Technical Field

[0001] The invention relates to a dry-type transformer and an anti-seismic structure of the dry-type transformer, belonging to the technical field of transformers. Background Art

[0002] Transformers are a type of electrical equipment that mainly use the principle of electromagnetic induction to change AC voltage. They are mainly composed of coils and iron cores. If a traditional transformer is operated in a static operating environment, it can be used normally by simply welding the transformer base to the foundation channel steel or bolting it to the foundation channel steel. However, if it is operated in a non-static environment, the transformer fasteners may loosen, the core and coil components may shift, and in severe cases, the transformer may discharge or even burn, reducing the operating quality of the transformer and shortening the transformer's service life. Summary of the invention

[0003] The purpose of the present invention is to provide a dry-type transformer and a seismic-resistant structure of the dry-type transformer, so as to solve the loosening problem caused by the transformer running in a non-static environment.

[0004] To achieve the above object, the solution of the present invention includes:

[0005] A dry-type transformer earthquake-resistant structure of the present invention comprises a shell having a bottom for fixing a transformer base, and two opposite side walls of the shell are respectively provided with pulling devices connected to a clamp body fixing the transformer coil from the top; the pulling devices are used to generate pulling force on the clamp body in the same straight line.

[0006] The transformer coil is fixed from the top by a pulling device and the bottom is fixed by the shell to prevent the transformer coil from changing, which effectively solves the loosening problem that may be caused by the operation of the transformer in a non-static environment.

[0007] Furthermore, the pulling device includes an inclined body fixed on the clamp body and connecting pieces respectively connecting the inclined body and the side wall of the shell at both ends; two fixing holes are opened on the inclined body, and each fixing hole on the inclined body is connected to the side wall of the shell through connecting pieces facing different directions.

[0008] By fixing the clamp body in different directions from both ends, the stability of the transformer coil is further improved.

[0009] Furthermore, the inclined body also includes a pin and an ear plate fixed to the pin, the pin is used to pass through the mounting holes on the two opposite side walls of the clamp body to achieve the connection between the inclined body and the clamp body; the fixing holes are opened at symmetrical positions on the ear plate.

[0010] Through the mounting holes on the two opposite side walls of the inclined body and the axis pin of the inclined body, the inclined body can be naturally drooped after installation. The angle of the inclined body can be adjusted according to the actual position of the fixing pin of the transformer housing. Through the fixing holes symmetrically opened on the ear plate, the pulling force in different directions passing through the fixing holes can be uniform and more fixed.

[0011] Furthermore, the connecting piece includes a turnbuckle bolt connected to the connecting hole of the inclined body, and the other end of the turnbuckle bolt is connected to a fixing pin on the transformer housing.

[0012] The length of the basket bolt can be adjusted according to the distance between the inclined body and the fixing pin of the transformer housing.

[0013] A dry-type transformer comprises a clamping body for clamping a transformer coil with a transformer base; and a shell with a bottom for fixing the transformer base. Two opposite side walls of the shell are respectively provided with pulling devices connected to the clamping body for fixing the transformer coil from the top; and the connecting device is used to generate pulling force on the clamping body in the same straight line.

[0014] Furthermore, the connecting device includes an inclined body fixed on the clamp body and connecting pieces with two ends respectively connecting the inclined body and the side wall of the shell; two fixing holes are provided on the inclined body, and each fixing hole on the inclined body is connected to the side wall of the shell through connecting pieces facing different directions.

The ear plate 32 is fixed in the middle of the pin shaft 31. The two ends of the pin shaft 31 are used to pass through two mounting holes reserved on the side of the U-shaped plate. When the inclined body 3 is installed, the ear plate 32 naturally hangs down, and is used to adjust the angle of the inclined body according to the actual position of the fixing pin 5 of the transformer housing, so as to achieve 180° angle adjustment of the inclined body.

In this embodiment, a basket bolt 4 is used for connection. The length of the basket bolt 4 is adjusted according to the distance between the inclined body 3 and the fixing pin 5 of the transformer housing. Generally, the adjustable range varies according to the model of the basket bolt 4. Both ends of the basket bolt 4 are fastened with bolts.

[0024] The transformer housing fixing pin 5 is installed on the top of the side of the transformer housing and is used to connect and fix with the basket bolt 4; the height is limited according to the height of the transformer body, and the general design angle is between -30° and 30° between the inclined body and the plane.

[0025] The bottom channel steel 6 of the transformer housing is installed at the bottom of the transformer housing and connected to the transformer base. The bottom channel steel 6 of the transformer housing has mounting holes reserved at appropriate positions, and the bottom channel steel 6 of the transformer housing is fastened to the transformer base 2 with bolts.
