Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage copper busbar fixing, in particular to a low-voltage copper busbar fixing structure for a rectifier transformer. Background Art

[0002] A rectifier transformer is a power transformer for rectifier equipment. Rectifier equipment is characterized by AC input on the primary side and DC output on the secondary side after passing through rectifier elements. Current conversion is a general term for three operating modes: rectification, reverse current, and frequency conversion, with rectification being the most widely used. A transformer used as a power source for rectifier equipment is called a rectifier transformer. Most industrial rectified DC power is derived from the AC grid through a rectifier transformer and rectifier equipment. Low-voltage copper busbars, a copper material similar to copper foil used in transformers, are primarily used to transmit high currents. They are typically installed on the low-voltage side of the transformer, connecting the receiving cabinet, capacitor cabinet, or distribution cabinet to ensure stable and safe power transmission. A rectifier transformer's low-voltage copper busbar typically consists of a carrier and several conductive rods mounted on the carrier. The rods pass through holes in the carrier and are secured by clamps. An insulating layer is cast around the center of the conductive rods where they meet the carrier to ensure electrical isolation and safety.

[0003] The existing low-voltage copper busbars of rectifier transformers are usually locked and fixed with insulators and copper busbars with bolts. Tools are usually required for installation, and the workers are relatively cumbersome to operate. In addition, the connection parts are exposed to the external environment for a long time and are easily corroded, resulting in a shortened service life. Therefore, it is particularly important to improve the existing low-voltage copper busbar fixing structure of rectifier transformers and design a new low-voltage copper busbar fixing structure of rectifier transformers to solve the above technical defects and improve the practicality of the overall low-voltage copper busbar fixing structure of rectifier transformers.

[0021] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A rectifier transformer low-voltage copper busbar fixing structure, including a connecting copper busbar 1, two sets of jacks 11 are opened on the top of both ends of the connecting copper busbar 1, and threaded holes 42 are opened on both sides of the jacks 11. The outer sides of the two ends of the connecting copper busbar 1 are provided with fixing blocks 3, and the outer sides of the fixing blocks 3 are provided with slots 31. The top and bottom of the slots 31 are slidably connected with two sets of card blocks 5. The card blocks 5 are located at one end away from the slots 31 and are fixedly connected to the inside of the fixing blocks 3 with springs 6. The slots 31 and the connecting copper busbar 1 are designed to be adapted to each other, the jacks 11 and the card blocks 5 are designed to be adapted to each other, and the bottom of the fixing blocks 3 is provided with a fixing block 3. The insulator 2 is fixedly connected to the part, and a damper 61 is provided inside the spring 6. When the low-voltage copper bar fixing structure of the rectifier transformer is put into use, the connecting copper bar 1 is inserted into the inside of the slot 31. The connecting copper bar 1 first squeezes the card block 5 out of the inside of the slot 31. When the socket 11 is aligned with the card block 5, the spring 6 rebounds and pushes the card block 5 into the inside of the socket 11, thereby fixing the connecting copper bar 1 to the inside of the fixing block 3. The operation is simple and convenient, which improves work efficiency. The fixing block 3 wraps the connection, protects the internal connection, avoids external erosion, and extends the service life.

[0025] Furthermore, a threaded hole 42 is provided on the outside of the fixed block 3, and a threaded groove 43 is provided on the end of the clamping block 5 away from the spring 6. A threaded rod 41 is provided inside the threaded hole 42 on the outside of the fixed block 3, and the threaded rod 41 is adapted to the threaded hole 42 and the threaded groove 43. The end of the threaded rod 41 away from the fixed block 3 is fixedly connected to the rotating block 4, and a plurality of groups of equally spaced stripes are provided on the outside of the rotating block 4 to facilitate workers to rotate the rotating block 4. When the low-voltage copper busbar fixing structure of the rectifier transformer is put into use, the threaded rod 41 is inserted into the threaded hole 42 on the outside of the fixed block 3, passes through the slot 31, connects the copper busbar 1 and the clamping block 5, and further strengthens the fixation of the connecting copper busbar 1.

[0026] Among them, a sealing layer 7 is provided inside the slot 31. When the rectifier transformer low-voltage copper busbar fixing structure is put into use, the sealing layer 7 improves the airtightness inside the slot 31, avoids external erosion, protects the internal connections, and extends the service life.

[0027] When the jack 11 is in the closed position, the spring 6 will push the block 5 out of the slot 31, and then the spring 6 will push the block 5 into the slot 11, thereby fixing the jack 1 in the fixed block 3. Then, the threaded rod 41 will be inserted into the threaded hole 42 on the outside of the fixed block 3, passing through the slot 31, the jack 1 and the block 5, thereby further strengthening the fixation of the jack 1. The operation is simple and convenient, and the work efficiency is improved. The fixed block 3 wraps the connection, and the sealing layer 7 improves the airtightness of the inside of the slot 31, protects the internal connection, avoids external erosion, and prolongs the service life. Compared with the existing rectifier transformer low-voltage copper bar fixing structure, the utility model can improve the overall practicality of the rectifier transformer low-voltage copper bar fixing structure through design.
