Description

Technical Field

[0001] This invention relates to the field of new energy storage technology, and more specifically to a transformer inductance adjustment device for new energy storage. Background Technology

[0002] Traditional inductance regulating devices typically employ a single mechanical sliding contact structure; that is, by changing the contact position of the sliding contact on the winding, the effective number of turns is altered, thereby adjusting the inductance value. However, the current of the entire circuit converges at a single contact, which is prone to wear and oxidation due to long-term mechanical sliding and arc erosion, leading to increased contact resistance. This can not only cause localized overheating and accelerated insulation aging, resulting in contact welding or open circuits, but also potentially cause the entire inductance regulating function to fail due to the failure of this single contact, resulting in low reliability. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a transformer inductance adjustment device for new energy storage to solve the technical problem of single contact reliability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A transformer inductance regulation device for new energy storage includes:

[0006] The winding assembly has multiple contact points;

[0007] At least two contact blocks are arranged in parallel and move synchronously relative to the winding group so that they can selectively make contact with any of the contact positions to conduct electricity.

[0008] as well as

[0009] At least two elastic elements are provided in a one-to-one correspondence with at least two contact blocks. Each elastic element deforms through the corresponding contact block to accumulate an elastic force that drives the contact block to move toward the winding assembly, thereby providing a constant contact pressure to the contact block.

[0010] Furthermore, the adjustment device further includes: at least two first support seats, each of which is correspondingly arranged with the contact block and has a cavity for accommodating the elastic element. One end of the contact block extends into the cavity for connection with the elastic element, and the other end extends out of the cavity for contact with the contact position.

[0011] Furthermore, along the direction of the elastic force, the first support is provided with a guide groove, and the contact block is provided with a trigger rod, which is used to slide and connect to the guide groove under the action of the elastic force.

[0012] Furthermore, the first support base is provided with a trigger switch, which is located at the end of the guide groove and is triggered by the trigger rod.

[0013] Furthermore, the contact block is equipped with a temperature monitoring module for monitoring the temperature of the contact block.

[0014] Furthermore, the elastic element is a spring.

[0015] Furthermore, the adjustment device also includes a second support base, wherein the first support base and the second support base are detachably connected.

[0016] Furthermore, the adjustment device also includes a third support base, wherein the second support base is inserted into the third support base.

[0017] Furthermore, the adjusting device also includes a rotatable threaded rod, and the third support seat is sleeved on the threaded rod.

[0018] Compared to existing technologies, this invention offers the following advantages: Firstly, the use of at least two parallel contact blocks enables hardware redundancy in the current path. Even if one contact block fails completely due to an accident, the remaining contact blocks can still maintain circuit continuity, ensuring uninterrupted inductance adjustment and improving the device's fault tolerance and operational reliability. Secondly, each contact block is subjected to contact pressure by an independent elastic element, ensuring that the contact pressure remains within a constant range throughout the entire allowable wear range of the contact block. This avoids pressure attenuation due to wear, thereby ensuring low resistance and stability of the contact resistance throughout the entire cycle, reducing heat generation and energy loss. Simultaneously, the elastic elements of each contact can automatically compensate for processing or assembly errors, enabling each contact block to establish reliable contact under the action of elastic force. Furthermore, each contact block, under the action of its corresponding elastic force, can better resist the instantaneous disengagement tendency caused by external vibration, thus maintaining continuous stability of the contact state and preventing current flashover and arc discharge caused by vibration.

[0032] The present invention will be further described in detail below through specific embodiments:

[0033] In embodiments of the present invention, such as Figures 1-5 As shown in b, the transformer inductance adjustment device for new energy storage includes: a winding group 1, at least two contact blocks 2, and at least two elastic elements 3; the winding group 1 is provided with multiple contact positions 100; the at least two contact blocks 2 are arranged in parallel and can move synchronously relative to the winding group 1 and selectively make contact with any of the contact positions 100 to conduct electricity; the at least two elastic elements 3 are arranged one-to-one with the at least two contact blocks 2, and each elastic element 3 deforms through the corresponding contact block 2 to accumulate elastic force to drive the contact block 2 to move toward the winding group 1, so as to provide a constant contact pressure to the contact block 2.

[0034] Specifically, in this embodiment of the invention, the winding group 1 is provided with a plurality of contact positions 100 along its length direction, and different contact positions 100 correspond to different numbers of turns of the winding group 1; for this purpose, a movable contact group is provided to adjust the moving distance of the contact group so that it contacts and conducts with different contact positions 100, thereby adjusting the inductance value by changing the effective number of turns of the winding group 1.

[0035] In this embodiment of the invention, the contact group includes at least two contact blocks 2 (this embodiment uses two contact blocks 2 as an example). The two parallel contact blocks 2 are connected to the current path, making them contact the same contact position 100. When one contact block 2 fails completely due to an accident, the remaining contact block 2 can still maintain circuit continuity. That is, the contact group is divided into two independently arranged contact blocks 2. Under normal circumstances, the two contact blocks 2 jointly undertake the conduction work, and when an accident occurs causing one to stop working, the other can still be guaranteed to work normally, ensuring that the function of this regulating device is not interrupted and improving the stability and reliability of the device. Of course, more than two contact blocks 2 can be provided, which is not limited here.

[0036] In this embodiment of the invention, to maintain a constant contact pressure even when the contact block 2 experiences increased wear, and to resist vibrations caused by movement or other external disturbances, each contact block 2 is connected to an elastic element 3. Specifically, when the contact block 2 is connected to the circuit and makes contact with or abut against the winding assembly 1, the elastic element 3 is compressed and partially deformed by the contact block 2, with the compression direction being away from the winding assembly 1. Thus, the elastic element 3 has the capacity to accumulate elastic force to drive the contact block 2 toward the winding assembly 1. When the contact surface of the contact block 2 wears due to force majeure, within the allowable wear range, the elastic force of the elastic element 3 can continuously provide a constant and appropriate contact pressure to the contact block 2, ensuring that the contact block 2 is in close contact with the contact position 100, reducing contact resistance and arcing. In other words, the elastic element 3 can automatically compensate for the portion of the contact block 2 lost due to wear, processing, or assembly, avoiding pressure attenuation caused by external factors, thereby ensuring low resistance and stability of the contact resistance throughout the entire cycle, reducing heat generation and energy loss.

[0037] In addition, because the elastic element 3 has elastic force, when the contact block 2 vibrates due to movement or external factors, the vibration is first absorbed by the elastic element 3 to better resist the instantaneous disengagement tendency caused by external vibration, thereby maintaining the continuous stability of the contact state and avoiding current flashover and arc discharge caused by vibration.

[0038] This embodiment achieves redundancy backup through at least two independently arranged contact blocks 2, eliminating the possibility of a single point of failure causing the entire device to open circuit or fail. Furthermore, by providing an elastic element 3 at each contact block 2, the elastic force of the element 3 provides a stable and adaptive contact pressure to each contact block 2, ensuring low resistance and stability of the contact resistance during its service life, reducing heat generation and energy loss. Simultaneously, the elastic element 3 can automatically compensate for errors in the contact blocks 2, and each contact block 2 can establish reliable and effective contact under its own elastic force, achieving automatic current distribution among multiple parallel paths and reducing the current load on each contact block 2. Moreover, the elastic force of the element 3 can resist the instantaneous disconnection tendency caused by external vibration, maintaining continuous stability of the contact state and avoiding current flashover and arcing caused by vibration.

[0039] like Figures 3-5 As shown in b, in one embodiment, the adjusting device further includes: at least two first support seats 4, each of which is correspondingly arranged with the contact block 2 and has a cavity 400 for accommodating the elastic member 3. One end of the contact block 2 extends into the cavity 400 for connection with the elastic member 3, and the other end extends out of the cavity 400 for contact with the contact position 100.

[0040] Specifically, in order to integrate the contact block 2 and the elastic element 3, the same number of first support seats 4 are provided according to the number of contact blocks 2 and elastic elements 3. For example... Figure 5 As described in b, the first support base 4 has a cavity 400, the elastic member 3 is surrounded by the cavity 400, and one end of the contact block 2 extends into the cavity 400 and is connected to one end of the elastic member 3; while its other end extends out of the cavity 400 to cooperate with the corresponding contact position 100. In this way, the elastic force of the elastic member 3 can be accurately transmitted to the contact block 2 along a preset path to ensure that the direction of the provided contact pressure is constant and to prevent the contact block 2 from getting stuck. In addition, the first support base 4 can form a larger heat dissipation area when the contact block 2 is energized to reduce the operating temperature of the contact block 2, which can suppress or slow down the wear of the contact block 2 and maintain stable contact resistance.

[0041] like Figure 5 a and Figure 5 As shown in b, in one embodiment, the first support 4 is provided with a guide groove 401 along the direction of the elastic force, and the contact block 2 is provided with a trigger rod 200, which is used to slide and connect to the guide groove 401 under the action of the elastic force.

[0042] Specifically, to constrain the movement path of the contact block 2 and ensure its continuous and tight contact with the winding assembly 1, this embodiment provides one or more guide grooves 401 at the first support 4, the guide grooves 401 being arranged along the direction of the elastic force, and an insulated trigger rod 200 extending into the guide groove 401 at the contact block 2. Thus, when the contact block 2 moves due to the elastic member 3, the trigger rod 200 can move along with it and slide relative to the guide groove 401. Because the guide groove 401 constrains the movement path of the trigger rod 200, the movement path of the contact block 2 is constrained, thereby ensuring tight contact of the contact block 2 under the constant contact pressure provided by the elastic member 3.

[0043] Furthermore, such as Figure 5 a and Figure 5 As shown in b, in one embodiment, the first support base 4 is provided with a trigger switch 402, which is located at the end of the guide groove 401 and is triggered by the trigger rod 200. Specifically, in order to quickly respond to the fault when the wear of the contact block 2 reaches or exceeds the preset maximum value, this embodiment sets the trigger switch 402 at the end of the guide groove 401 by setting the trigger switch 402 at the first support base 4. Under normal operation, the trigger rod 200 is located at the beginning of the guide groove 401 and is arranged at a distance from the trigger switch 402. Because there is a gap between the two, the trigger switch 402 is not triggered, and the contact block 2 is within the normal wear value at this time. Conversely, when the wear of the contact block 2 intensifies, under the action of the elastic force of the elastic element 3, the contact block 2 will be pushed to continuously move towards the winding group 1 until a constant contact pressure is formed. Then, due to the movement of the contact block 2, the trigger rod 200 gradually moves towards the end of the guide groove 401, so as to realize the synchronous movement of the trigger rod 200 while dynamically adjusting the contact block 2. When the wear value of contact block 2 reaches its maximum, trigger rod 200 is moved to the end of guide groove 401 and triggers trigger switch 402, so that trigger switch 402 can quickly grasp the wear condition of contact block 2 after responding.

[0044] Furthermore, if the vibration intensifies and the elastic element 3 cannot counteract it, even if the contact block 2 has not reached its maximum wear value, the vibration will still cause the contact block 2 to move, potentially causing the trigger rod 200 to briefly trigger the trigger switch 402. To avoid this false triggering, in this embodiment, the contact block 2 is equipped with a temperature monitoring module to monitor its temperature. Specifically, since the contact blocks 2 are arranged in parallel, when one fails, the current in the remaining contact blocks 2 will increase, potentially leading to overheating and accelerating the failure of the remaining contact blocks 2. Therefore, a temperature monitoring module is installed at or near each contact block 2. When a contact block 2 fails, the current in the other contact blocks 2 increases, causing their temperatures to rise; by monitoring the temperature of each contact block 2, it is possible to promptly detect whether the corresponding contact block 2 has failed. Moreover, the response of the trigger switch 402 combined with the temperature monitoring module can prevent misjudgments caused by false triggering. Alternatively, since the vibration is a brief trigger, a trigger time threshold is set for the trigger switch 402, so that only a continuous trigger for a certain period of time can be considered a valid signal; and / or, synchronous feedback is provided through the temperature of each contact block 2 to facilitate the identification of whether the "brief failure signal" is caused by accidental contact due to external reasons or the "real failure signal" is caused by wear. Preferably, the elastic element 3 is a spring.

[0045] like Figure 3 , Figure 4 As shown, in one embodiment, the adjustment device further includes a second support base 5, wherein the first support base 4 and the second support base 5 are detachably connected. Specifically, to facilitate the replacement of failed contact blocks 2, this embodiment provides a second support base 5. The second support base 5 not only integrates all contact blocks 2 at that location, but also enables independent replacement of each contact block 2 through its detachable connection with the first support base 4, thereby modularizing each contact block 2 and reducing maintenance costs.

[0046] like Figure 3 , Figure 4 As shown, in one embodiment, the adjusting device further includes a third support base 6, to which the second support base 5 is inserted. Specifically, to modularize the second support base 5 for easier maintenance, this embodiment detachably mounts the second support base 5 to the third support base 6, for example, by connecting them via a plug-in connection, thereby improving maintenance efficiency. Preferably, to allow the contact block 2 to move between each contact position 100 to adjust the inductance, in this embodiment, such as... Figure 1 , Figure 2 As shown, the adjusting device further includes a rotatable threaded rod 7, and the third support 6 is sleeved on the threaded rod 7.
