Description

Technical Field

[0001] This utility model relates to the field of transformer heat dissipation, specifically to the heat dissipation structure of an electric step-up transformer. Background Technology

[0002] In the field of power equipment, electric step-up transformers are key equipment that play an important role in many power transmission and conversion scenarios. The stability and reliability of their operation are directly related to the efficiency and safety of the entire power system.

[0003] However, existing electric stirring step-up transformers have many problems. On the one hand, under long-term high-current operation, the three-phase windings inside the transformer generate a large amount of heat, causing the temperature to rise sharply. Conventional air conditioning cooling methods are ineffective in controlling the internal temperature, which not only affects the normal operation of the transformer but also increases the probability of failure, shortens its service life, and reduces its operational stability and reliability, making it difficult to adapt to harsh working environments and long-term operation requirements. On the other hand, existing heat dissipation structures lack simple and stable fixing methods for installing cooling fans, resulting in inconvenient installation and poor operational stability. Furthermore, the heat dissipation structure is difficult to flexibly adapt to different types of cooling fans and is not convenient for installing cooling fans in different locations, greatly limiting the applicability of the equipment. Therefore, those skilled in the art have provided a heat dissipation structure for electric stirring step-up transformers to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies and provide a heat dissipation structure for an electric stirring step-up transformer. By using a cooling fan and an adjustable mounting carrier, it solves the problems of high internal temperature in existing electric stirring step-up transformers and poor adaptability of heat dissipation equipment installation.

[0005] The objective of this utility model is achieved through the following means:

[0006] The heat dissipation structure of the electric stirring step-up transformer includes a casing and a cooling fan. The output end of the cooling fan is connected to one side of the casing. This cooling fan addresses the problem in the prior art where the internal three-phase winding temperature of the electric stirring step-up transformer is too high under long-term high-current operation and is difficult to control effectively using conventional air conditioning cooling methods. A bracket is provided on the bottom side of the cooling fan, and fixing bolts are installed on the bottom side of the bracket. A first support plate is provided on the bottom side of the bracket, and a second support plate is provided on one side of the first support plate. Side plates are provided at both ends of the first support plate, and a first sliding groove is transversely opened on the side plate. A second sliding groove is provided on the upper side. A first screw hole is provided at the end of the side plate facing the housing. A first screw is provided in the first screw hole. A clamping plate is rotatably engaged at the end of the first screw facing the housing. A stud is installed on the upper side of the end of the first support plate facing the second sliding groove. A second screw hole is provided at the end of the second support plate away from the second sliding groove. A second screw is provided in the second screw hole. One end of the second screw is rotatably engaged with the end of the first support plate. A third sliding groove is provided on the upper side of the second support plate. The cooling fan is fixedly connected to the third sliding groove on the second support plate by fixing bolts on the bottom side of the bracket.

[0007] Furthermore, the side plate is rotatably sleeved with the first screw through the first screw hole, and the clamping plate is pressed into contact with the outer wall of the shell.

[0008] Furthermore, the two ends of the first support plate and the second support plate are slidably engaged with the first groove on the side plate.

[0009] Furthermore, the second screw is threaded into the second screw hole on the second support plate, and the distance between the first support plate and the second support plate can be adjusted through the second screw.

[0010] Furthermore, a nut is connected to the stud, which can be used to fix the position of the first support plate.

[0011] The beneficial effects of this utility model are: by setting a cooling fan on one side of the housing and having its output end connected to the housing, it can effectively solve the problem of excessively high internal three-phase winding temperature of the electric stirring step-up transformer under long-term high-current operation and the difficulty of effectively controlling it with conventional air conditioning cooling methods, thus achieving a significant cooling effect, thereby reducing the transformer failure rate, extending its service life, improving operational stability and reliability, and enabling the electric stirring step-up transformer to adapt to more stringent working environments and long-term operation requirements.

[0012] By creating a first screw hole on the side plate and threading a first screw rod onto it, the inner side of the first screw rod rotates and engages with a clamping plate. The clamping plates on both sides, along with the first screw rod, clamp the plates to the sides of the housing to fix the side plate position. This structure is simple and stable, facilitating the installation and fixing of the cooling fan via bolts on the bracket, ensuring the stability of the cooling fan during operation. Furthermore, the first and second support plates are slidably engaged with the first sliding groove at both ends. A stud can be inserted through the second sliding groove and used with a nut to fix the position of the first support plate. Simultaneously, a second screw rod, rotatably engaged at one end of the first support plate, is threaded into the second screw hole on the second support plate, allowing adjustment of the distance between the first and second support plates. This structure enables the equipment to flexibly adapt to different types of cooling fans and facilitates installation of cooling fans in different locations, greatly improving the equipment's applicability.
