Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a fastening device for a transformer core. Background Art

[0002] In the field of power equipment, transformers are key components, and the fastening of their cores is of great significance for ensuring the normal operation of transformers and extending their service life. At present, the common transformer core fastening methods on the market mainly rely on the combination of bolts and nuts. Although this method can achieve the fastening effect to a certain extent, the operation is cumbersome and the fastening efficiency is low. In addition, during long-term operation, due to factors such as vibration and temperature changes, the bolts may become loose, thereby affecting the stable operation of the transformer. Therefore, the development of a fast and convenient transformer core fastening device has become an urgent problem to be solved in the current industry. Utility Model Content

[0003] The purpose of the utility model is to provide a fastening device for a transformer core to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fastening device for a transformer core, comprising a fastening seat, a base and a core body, slide rails are installed on both sides of the top of the fastening seat, a limit slider is slidably installed inside the slide rail, a soft magnet 1 is installed at one end of the limit slider, a base is placed on the top of the fastening seat, two groups of limit columns are installed on both sides of the base, and a soft magnet 2 is installed inside the base.

[0005] A base is installed at the bottom of the iron core body. When in use, the base is placed on the fastening base. At this time, the limit slider on the top of the fastening base is moved to the side of the base through the slide rail, so that the limit slider clamps the limit column. When the limit slider clamps out of the limit column, the limit slider will be adsorbed with the soft magnet on one side of the base, so that the limit slider can stably fasten the base. The biggest innovation of the utility model is that it adopts a sliding card fixing method, which eliminates the bolts and nuts in the traditional fastening method, simplifies the fastening steps, improves the fastening efficiency, and has a wider applicability. Through the implementation of the present invention, the problems of cumbersome operation and low fastening efficiency existing in the transformer iron core fastening method in the prior art can be effectively solved.

[0006] Preferably, the limit slider is magnetically connected to the soft magnet 1 and the soft magnet 2, and the bottom of the limit slider is clamped on the base.

[0007] Because the limit slider is magnetically connected to the soft magnet, the limit slider can maintain its position when it is clamped on the main base and will not move at will, thereby improving the stability during fixation.

[0008] Preferably, the limiting column is engaged with the limiting slider, and the limiting column is made of stainless steel.

[0009] The shape of the limit column can be engaged with the limit slider. When the limit column is engaged with the limit slider, the position of the base can be limited and fixed by the limit slider. The stainless steel material has good durability, ensuring that the device has a better service life.

[0010] Preferably, an iron core body is provided on the top of the base, and an upper frame is fixedly installed on the top of the iron core body.

[0011] The core body is the basic component of the transformer. The upper frame on the top of the core body can protect the top of the core body and facilitate the installation and fixation of the core body with other components.

[0012] Preferably, two groups of hanging ears are installed on both sides of the top of the upper rack, and through holes are opened inside the hanging ears.

[0013] The lugs and through holes can provide a place for external ropes to pass through and bind, making it convenient for workers to use an external crane to hoist and transfer the core body when installing the equipment.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] When the utility model is fixed, the limit slider on the top of the fastening seat is moved toward the side of the base through the slide rail, so that the limit slider clamps the limit column. When the limit slider clamps out of the limit column, the limit slider will be adsorbed with the soft magnet on one side of the base, so that the limit slider can stably fasten the base. The greatest innovation of the utility model is that it adopts a sliding clamping fixing method, which eliminates the bolts and nuts in the traditional fastening method, simplifies the fastening steps, improves the fastening efficiency, and has a wider applicability. Through the implementation of the present invention, the problems of complicated operation and low fastening efficiency existing in the transformer core fastening method in the prior art can be effectively solved.

[0020] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices and / or systems described herein. However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0021] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0022] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0023] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0024] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first member, component, region, layer, or portion referred to may also be referred to as the second member, component, region, layer, or portion.
