Abstract
Description
Technical Field
[0001] This utility model relates to the field of DC current transformer technology, specifically to a detachable DC current transformer support structure. Background Technology
[0002] A DC current transformer is a device used to measure the value of DC current. It is commonly used in DC transmission systems for current measurement, feedback, control, and protection. Its working principle is similar to that of an AC current transformer; it converts DC current into a smaller current through the ratio of the primary to secondary windings, thus facilitating measurement and protection.
[0003] Currently, the detachable DC current transformer support structure is mostly an integrated design. This structure lacks convenient disassembly, which leads to cumbersome installation and maintenance of the transformer. At the same time, the disassembly process is prone to wear and tear, causing positioning misalignment, which affects the positioning accuracy of the transformer and is not conducive to subsequent use.
[0004] In summary, this utility model solves the problems in the background art by designing a detachable DC current transformer support structure. Utility Model Content
[0005] The purpose of this invention is to provide a detachable DC current transformer support structure to solve the problems mentioned in the background art.

[0025] For examples, please refer to Figure 1-3 This utility model provides a technical solution:
[0026] A detachable DC current transformer support structure includes a transformer body 1 and a support fixing plate 2 disposed below the transformer body 1. The top surface of the transformer body 1 is provided with bolt holes 101, and the bottom of the transformer body 1 is provided with a connecting plate 3. The top surface of the connecting plate 3 is provided with guide holes 301, limiting holes 302 and screw holes 303 respectively. The bottom surface of the connecting plate 3 is fixedly installed with contact blocks 304. The top surface of the support fixing plate 2 is provided with guide posts 201, limiting posts 202 and contact grooves 203 respectively. The top of the guide posts 201 is provided with locking posts 204, and the bottom of the locking posts 204 is provided with friction blocks 205.
[0027] Specifically, a fastening bolt is inserted into the bolt hole 101, and the fastening bolt is matched with the bolt hole 303;
[0028] In this embodiment, the bolt hole 101 and the screw hole 303 are mainly used to facilitate threaded locking with the fastening bolt, thereby achieving the function of fixing the transformer body 1 and the connecting plate 3.
[0029] Specifically, the contact block 304 is made of silicone rubber, the inner wall of the contact groove 203 is provided with anti-slip texture, the outer surface of the contact block 304 is fitted with the inner wall of the contact groove 203, the limiting posts 202 are respectively located on the top side of the support fixing plate 2, the limiting hole 302 and the limiting post 202 are correspondingly set, and the inner wall of the limiting hole 302 is in close contact with the outer surface of the limiting post 202.
[0030] In this embodiment, the contact block 304 is mainly used to make contact with the contact groove 203, and the limiting post 202 is mainly used to make contact with the limiting hole 302, thereby achieving the function of accurately positioning the connecting plate 3 and the supporting fixing plate 2, and ensuring the positional accuracy of the transformer body 1.
[0031] Specifically, the guide post 201 is symmetrically arranged on the top surface of the support fixing plate 2, and the outer surface of the guide post 201 is in clearance fit with the inner wall of the guide hole 301. The bottom end of the locking post 204 rotates eccentrically with the guide post 201 through an eccentric part, and the diameter of the locking post 204 is the same as that of the guide post 201. The friction block 205 is a wavy anti-slip silicone pad, and the bottom surface of the friction block 205 forms frictional contact with the top surface of the connecting plate 3.
[0032] In this embodiment, the guide post 201 is mainly used to contact the guide hole 301, causing the locking post 204 to pass through the inner wall of the guide hole 301 and move to the top of the connecting plate 3. The locking post 204 is mainly used to rotate eccentrically with the guide post 201, causing the locking post 204 to drive the friction block 205 to shift, so that the friction block 205 forms a friction self-lock with the top surface of the connecting plate 3, thereby achieving the function of conveniently fixing the connecting plate 3 and the support fixing plate 2, and also facilitating subsequent disassembly and maintenance.
[0033] The working process of this utility model is as follows: When using a detachable DC current transformer support structure, the support fixing plate 2 is installed in the required position. Then, the transformer body 1 is moved to contact the connecting plate 3. With the bolt holes 101 and 303 combined, the transformer body 1 and the connecting plate 3 are fixedly installed by tightening bolts. Then, the connecting plate 3 is moved closer to the support fixing plate 2. During this process, the limiting post 202 and the limiting hole 302 are ensured to make contact. As the limiting post 202 and the limiting hole 302 approach each other... As the contact block 304 gradually engages with the inner wall of the contact groove 203, the guide post 201 drives the locking post 204 through the guide hole 301 until the limiting post 202 is in complete contact with the limiting hole 302. At this point, the locking post 204 moves above the connecting plate 3. Subsequently, the locking post 204 is rotated eccentrically, causing the friction block 205 to rotate. This results in frictional contact force between the bottom surface of the friction block 205 and the top surface of the connecting plate 3, thereby enabling convenient installation or disassembly between the connecting plate 3 and the supporting fixing plate 2, meeting the needs of users.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
