Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery technology, and in particular to a battery anti-open-circuit automatic freewheeling module. Background Technology
[0002] In the DC power system of a substation, the battery bank is an energy storage device and an essential backup power source for the substation. As the last line of defense for the DC system, the battery can reliably provide working power to the important primary and secondary equipment in the substation in the event of AC power failure. In order to achieve the corresponding voltage level of DC power, a battery bank is usually composed of dozens or even hundreds of battery cells connected in series. When a single battery cell is open-circuited, it will cause the entire battery bank to fail.
[0003] Currently, the solution for open-circuit follow current in substation battery banks typically involves connecting adjacent batteries in series using jumper modules. The connecting wires between batteries and the jumper modules are all connected to the battery terminals. When an open circuit occurs, the jumper modules automatically provide follow current to ensure the battery bank's normal output power. The affected battery is then removed and replaced to ensure the overall operation of the battery bank. However, existing systems require the connecting wires and jumper modules to remain connected when replacing an open-circuit battery, making the operation cumbersome.
[0004] Therefore, in response to the above problems, a battery anti-open-circuit automatic freewheeling module has been developed to facilitate the replacement of batteries that have experienced open circuits. Utility Model Content
[0005] To overcome the drawback of existing devices that require maintaining the connection of connecting wires and jumper modules when replacing batteries with open circuits, which is cumbersome, this invention provides a battery anti-open circuit automatic freewheeling module that facilitates the replacement of batteries with open circuits.
[0006] The technical solution of this utility model is: a battery anti-open-circuit automatic current-running module, including a mounting frame, a first connector, connecting wires, moving contacts, a clamping frame, guide posts, stationary contacts, a first wiring component, an automatic current-running component, and a second wiring component. The mounting frame is connected to the first connectors on both the left and right sides, and connecting wires are connected to the adjacent sides of the first connectors. Moving contacts are connected to the ends of the connecting wires. A clamping frame is connected between the moving contacts. Multiple guide posts are connected to the upper middle part of the mounting frame. The guide posts are slidably connected to the clamping frame. Stationary contacts are symmetrically connected to the bottom left and right sides of the mounting frame. The bottom of each stationary contact is connected to the first wiring component. An automatic current-running component is connected to the top of the mounting frame. Second wiring components are connected to the non-adjacent sides of the first connectors.
[0007] Furthermore, it also includes a front panel and a back panel, with the front panel connected to the rear side of the mounting frame and the back panel connected to the front side of the mounting frame.
[0008] Furthermore, it also includes a first spring, and each guide post is connected to the clamping frame by a first spring.
[0009] Furthermore, the automatic continuous current assembly includes a second connector and an integrated module. The second connector is connected to the top of the mounting frame, and the integrated module is connected to the upper rear side of the backplate. All stationary contacts are connected to the integrated module.
[0010] Furthermore, it also includes a mounting base, a locking element, and a second spring. The mounting base is connected to the rear side of the middle of the back plate, and the locking element is slidably connected to the mounting base. The second spring is connected between the locking element and the mounting base. When the clamping frame moves, it squeezes the locking element to make it slide forward. The second spring is compressed. After the clamping frame is separated from the locking element, the locking element is driven to slide backward and reset under the action of the second spring. The locking element locks and limits the clamping frame.
[0011] Furthermore, the lower rear side of the locking element has a sloping structure.
[0012] The beneficial effects are as follows: This utility model connects to the battery through the first wire and then connects to each other through the second wire. When a single battery cell is open-circuited, the moving contact is controlled to disconnect from the stationary contact through the integrated module. At this time, it is only necessary to remove the first wire from the battery, which makes it easy to replace the open-circuited battery. Attached Figure Description

Detailed Implementation
[0021] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] A battery open-circuit protection automatic freewheeling module, such as Figures 1-7 As shown, the system includes a mounting frame 1, a front plate 2, a back plate 3, a first connector 4, a connecting wire 5, a moving contact 6, a clamping frame 7, guide posts 8, a first spring 9, a stationary contact 10, a first wiring 11, an automatic current-continuing assembly, a second wiring 14, a mounting base 15, a locking element 16, and a second spring 17. The front plate 2 is connected to the rear side of the mounting frame 1, and the back plate 3 is connected to the front side of the mounting frame 1. The first connector 4 is connected to both the left and right sides of the mounting frame 1. The connecting wire 5 is connected to the adjacent side of the first connector 4. The moving contact 6 is connected to the end of the connecting wire 5. The clamping frame 7 is connected between the moving contacts 6. Two guide posts 8 are connected to the upper middle part of the mounting frame 1. The guide posts 8 are slidably connected to the clamping frame 7. Each of the first springs 9 is connected to the clamping frame 7. Static contacts 10 are symmetrically connected to the bottom left and right sides of the mounting frame 1. Each static contact 10 has a first wiring 11 connected to its bottom. An automatic current-continuing assembly is connected to the top of the mounting frame 1. The automatic current-continuing assembly includes a second connector 12 and an integrated module 13. The second connector 12 is connected to the top of the mounting frame 1. An integrated module 13 is connected to the upper rear side of the back plate 3. Each static contact 10 is connected to the integrated module 13. Second wiring 14 is connected to each non-adjacent side of the first connector 4. A mounting base 15 is connected to the middle rear side of the back plate 3. A locking element 16 is slidably connected to the mounting base 15. A second spring 17 is connected between the locking element 16 and the mounting base 15.
[0023] In use, this invention first requires connecting the first wiring 11 to the positive and negative terminals of the battery. Then, the adjacent modules are connected via the second wiring 14. During normal operation of the battery pack, current flows from the positive terminal of the first battery, through the first wiring 11, stationary contact 10, connecting wire 5, first connector 4, and second wiring 14, sequentially flowing from the positive to the negative terminal of each battery, finally exiting from the negative terminal of the last battery in series. When a battery experiences an open circuit, the integrated module 13 controls the clamping frame 7 to slide upwards, causing the moving contact 6 to disengage from the stationary contact 10. The first spring 9 is stretched and contacts the second connector 12, thus facilitating the connection within the integrated module. Under the action of 13 and the second connector 12, the bridging is achieved. When the clamping frame 7 moves, it squeezes the locking member 16 to make it slide forward. The second spring 17 is compressed by force. After the clamping frame 7 is separated from the locking member 16, the locking member 16 is driven to slide backward and reset under the action of the second spring 17. The clamping frame 7 is locked and limited by the locking member 16 to prevent the moving contact 6 from separating from the second connector 12. Then the single battery with open circuit can be replaced. After the replacement is completed, the locking member 16 is pulled forward and no longer locks and limits the clamping frame 7. At this time, under the action of the first spring 9, the clamping frame 7 is driven to slide downward and reset, so that the moving contact 6 contacts the stationary contact 10 again.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may 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.
