Description

Technical Field

[0001] The utility model relates to the technical field of electrical installation, in particular to a transition plate for the lead-out wire of a battery pack. Background Art

[0002] With the increasing dependence on battery systems in electrical device installation projects, the battery pack, as an important part of power supply, its reliability and safety have become the focus of attention. To ensure the stable operation of the power system, it is necessary to regularly conduct the capacity verification test of the battery to evaluate whether the actual capacity of the battery meets the design requirements.

[0003] According to the "Code for Construction and Acceptance of Batteries in Electrical Installation Engineering" (GB-50172-2012), to avoid damage to the battery poles due to the long-term weight of the power supply lead-out cables, a transition plate is usually used to connect the battery pack and the charging equipment. The transition plate is connected to the cables of the battery and the charger through the positive and negative terminal posts respectively, and the current path is established through the copper busbar inside. This method effectively solves the problem of the direct force of the cable on the pole, but when conducting the capacity verification test, the design of the traditional transition plate exposes the following deficiencies:

[0004] 1. Since the charging cabinet cable is used at a fixed position for a long time, its material will gradually harden, resulting in the need to forcibly bend the cable during the disassembly and reinstallation process before each capacity verification test to avoid contact with the terminal post. This operation is likely to cause damage or breakage of the cable insulation layer, increasing the maintenance cost and shortening the service life of the cable;

[0005] 2. When manually replacing the cable, that is, switching from the charging cabinet cable to the test instrument cable, improper operation is extremely likely to cause a short-circuit accident of the battery, which may not only damage the battery but also endanger the personal safety of the operator;

[0006] 3. To ensure that the current displayed by the test instrument accurately reflects the actual current value flowing through the battery, the staff usually needs to hold a detection instrument (such as a clamp-on ammeter) for real-time monitoring. However, this process is complex, not only time-consuming and laborious, but also inconvenient to operate in a high-voltage environment, increasing the possibility of human error. Summary of the Utility Model

[0007] The technical problem to be solved by the utility model is to provide a transition plate for the lead-out wire of a battery pack. The device adopts a new wiring method, which can directly disconnect the connection between the battery pack and the charging cabinet without frequently untying, moving, and reconnecting the positive and negative power cables of the charging cabinet, effectively solving the problem of damage and deformation of the cable.

[0008] To solve the above technical problems, the technical solution adopted by the utility model is:

[0009] A lead-out wire transition board for a battery pack, comprising a panel and a base box, wherein the panel and the base box are detachably connected. A terminal column body is vertically inserted at the upper end surface of the panel, and a display is arranged at the upper end surface of the panel. A strip-shaped hole is formed in the side of the base box, and a sliding groove is formed in the base box. A copper busbar plate is clamped in the sliding groove.

[0010] In a preferred solution, the terminal column body includes a first terminal column, a second terminal column, a third terminal column, a fourth terminal column, a fifth terminal column and a sixth terminal column; the first terminal column, the second terminal column and the third terminal column are arranged in parallel with the fourth terminal column, the fifth terminal column and the sixth terminal column, and a conductive column is arranged at the bottom of the terminal column body and penetrates through the panel.

[0011] In a preferred solution, a current transformer is sleeved on the second terminal column. The current transformer is connected to the display through a first wire row, and a knob switch is arranged on the first wire row.

[0012] In a preferred solution, the second terminal column and the fifth terminal column are connected to the display through a second wire row. The second wire row is buried at the bottom surface of the panel, and the end of the second wire row is connected to the power supply interface at the back of the display.

[0013] In a preferred solution, threaded holes are formed at the four corners of the panel and the base box, and screws are threadedly connected to the threaded holes to connect the panel and the base box into a whole.

[0014] In a preferred solution, the copper busbar plate slides along the sliding groove in a limited manner. A contact piece is arranged at the upper end surface of the copper busbar plate, and a side plate is vertically connected to the side of the copper busbar plate. The side plate penetrates through the strip-shaped hole.

[0015] A lead-out wire transition board for a battery pack has the following beneficial effects during actual use:

[0016] 1. By adding a quick-disconnect mechanism in the design, this device can easily disconnect the connection between the battery pack and the charging cabinet without damaging the cable. This avoids the wear and deformation of the insulation layer caused by frequent forced bending of the cable, significantly extends the service life of the cable, and reduces the maintenance cost and downtime;

[0017] 2. The built-in safety isolation mechanism of the device ensures that the battery pack will not be accidentally short-circuited when replacing the cable for testing. This design greatly reduces the safety hazards faced by operators and improves the safety factor of the entire maintenance process;

[0018] 3. This device integrates an intelligent current monitoring function, which can collect and accurately display the current data flowing through the battery in real time; it not only eliminates the cumbersome steps of manual use of hand-held detection instruments by staff, but also provides more intuitive data feedback, facilitating the rapid judgment of the battery state, and significantly improving the test efficiency and accuracy;

[0019] 4. The real-time current monitoring function of the device ensures that the current displayed by the test instrument is exactly the same as the current actually flowing through the battery, eliminates the human error that may be introduced by the previous manual detection, improves the reliability of the test data, and ensures the accuracy of the test results.
