[0021] The advantages of the phase loss protector test bench provided by this utility model are as follows: Compared with the prior art, in this utility model, the mounting plate 3 is located on the cabinet 1, and multiple test modules 2 are detachably plugged into the mounting plate 3. A control block 6 is detachably connected to the back of the mounting plate 3, and multiple interfaces of the control block 6 are connected to the corresponding test modules 2 via wires. Two spliced ​​control blocks 6 are connected through the communication port 12 to form a logic test circuit and transmit signals. The power board 9 provides power to the test modules 2. The device of this application can reasonably arrange the corresponding test modules 2 according to the test requirements, and different test circuits are formed by splicing the control blocks 6 and connecting them to the test modules 2. It is convenient to operate and has strong usability and ease of use.

[0022] In some embodiments of the phase loss protector test bench provided in this application, please refer to... Figure 2 and Figure 3 The mounting plate 3 has multiple through-holes for engaging with the test module 2. The test module 2 can be installed by inserting it into the through-holes.

[0023] Furthermore, the inner wall of the connector hole is equipped with a spring-loaded locking block, which fits tightly against the outer surface of the test module 2, thereby enhancing the stability of the test module 2 after installation. Additionally, a storage slot is provided on the back of the mounting plate 3 to store excess wires, making the overall layout of the test bench more organized. When the test module 2 needs to be replaced, it can be easily pulled outwards; thanks to the spring-loaded locking block, the removal process is smooth and prevents loosening or wobbling. When the replaced test module 2 is reinserted into the connector hole, the spring-loaded locking block automatically adjusts its position and re-fits tightly, ensuring the test module 2 functions normally. The storage slot has an internal divider structure, allowing for the categorization and storage of different types of wires, facilitating quick retrieval of the required wires and improving work efficiency.

When maintenance or replacement of control block 6 is required, simply pull out the insertion rod 5 to remove control block 6 from mounting plate 3; the operation is simple and quick, greatly improving maintenance efficiency.

[0026] In some embodiments of the phase loss protector test bench provided in this application, please refer to... Figure 2 The back of the mounting plate 3 is provided with multiple mounting bases 8, which are located around the corresponding insertion holes, and the positioning holes are provided on the mounting bases 8.

[0027] Meanwhile, the mounting base 8 provides reliable support for the components, preventing them from being affected by shaking or other factors during testing. The rational layout of multiple mounting bases 8 makes the installation of the entire phase loss protector test bench more orderly, facilitating collaborative work between various components and improving the overall performance of the test bench. For example, modules with different functions can be installed on different mounting bases 8 and connected to other lines or components through corresponding plug-in holes to achieve signal transmission and functional interaction, thereby meeting the needs for comprehensive and accurate testing of the phase loss protector.

[0028] In some embodiments of the phase loss protector test bench provided in this application, please refer to... Figure 3 The side of the control block 6 is provided with a snap-fit ​​groove, and the two snap-fit ​​grooves between two adjacent control blocks 6 are connected; two adjacent control blocks 6 are spliced ​​together by the cooperation of the snap-fit ​​pin 7 and the snap-fit ​​groove.

[0029] After the two control blocks 6 are connected, the two locking slots are linked. Specifically, the locking pin 7 is cross-shaped, with its horizontal part in the middle and its vertical part extending into the locking slot, facilitating insertion and removal by the operator. In actual use, when it is necessary to splice the two control blocks 6 together, align the communication port 12 of one control block 6 with the communication port 12 of the other control block 6, and then insert the locking pin 7 into the connected locking slot, so that the two control blocks 6 are tightly spliced. In this way, the communication ports 12 on the two control blocks 6 can be accurately linked, ensuring smooth communication. Moreover, this splicing method is simple and reliable, and can quickly complete the splicing operation of the control blocks 6, improving work efficiency. At the same time, the design of the locking pin 7 gives it good stability in the locking slot, making it less prone to loosening or falling off, further ensuring the reliability and stability of the control blocks 6 after splicing, providing a strong guarantee for the normal operation of the phase loss protector test bench. The locking pin 7 and the locking slot can realize the connection of the communication ports 12 on the two control blocks 6.

[0030] In some embodiments of the phase loss protector test bench provided in this application, please refer to... Figure 3 The test module 2 has connecting ears fixed at both ends, and the connecting ears are detachably connected to the mounting plate 3 by bolts.

[0031] Specifically, the connecting lugs are equipped with threaded holes that match the bolts. When it is necessary to install test module 2, simply align the threaded holes on the connecting lugs with the corresponding mounting holes on the mounting plate 3, screw in the bolts, and tighten them to quickly fix test module 2. This detachable connection method has many advantages. On the one hand, it facilitates operation during equipment maintenance, repair, or replacement of test module 2, allowing for quick removal of test module 2 from the mounting plate 3 without complicated tools or cumbersome steps, greatly improving work efficiency. On the other hand, it facilitates the replacement and upgrading of test module 2. With continuous technological development, it may be necessary to update test module 2 to adapt to new testing requirements and standards. Through this detachable connection, new test module 2 can be easily installed on the mounting plate 3, ensuring that the test bench always maintains good performance and adaptability. Moreover, during transportation, the detachable connection can prevent test module 2 from being damaged by vibration, ensuring the integrity and stability of the equipment. At the same time, this connection method also makes the assembly and debugging of the test bench more convenient. Technicians can flexibly adjust the position and angle of test module 2 according to the actual situation to achieve the best testing results. In daily use, if a fault or performance abnormality is found in test module 2, it can be quickly disassembled for inspection and repair, reducing equipment downtime and minimizing the impact on production or testing. Furthermore, test modules 2 of different specifications or functions can be installed on the test bench using this detachable connection method, enabling the integration of multiple testing functions to meet diverse testing needs.

[0032] In some embodiments of the phase loss protector test bench provided in this application, please refer to... Figure 2 Some of the plug holes are fitted with retaining sleeves, which are placed between the plug hole and the test module 2 to fill the gap between the test module 2 and the plug hole.

[0033] The retaining sleeve is typically made of an elastic material, such as rubber or plastic, possessing good flexibility and sealing properties. When test module 2 is inserted into the insertion hole, the retaining sleeve is compressed, tightly fitting around test module 2, effectively filling any gaps. This design not only ensures the stable installation of test module 2 within the insertion hole but also prevents external dust, moisture, and other impurities from entering and damaging the test module 2, improving the stability and reliability of the test bench. In practical use, this retaining sleeve significantly reduces testing errors caused by gap issues, resulting in more accurate test results. Moreover, due to the presence of the retaining sleeve, the insertion and removal of test module 2 is smoother, without loosening or jamming, facilitating testing operations. Simultaneously, the retaining sleeve has a longer service life, maintaining good performance even after multiple insertions and removals of test module 2, reducing costs and maintenance workload associated with frequent component replacements. For some test modules 2 that are smaller than the inner diameter of the insertion hole, the retaining sleeve ensures the stability of test module 2.

[0034] In some embodiments of the phase loss protector test bench provided in this application, please refer to... Figure 2 The inner wall of cabinet 1 is hinged with a swing arm, and the ball joint of power board 9 is connected to the end of the swing arm. The swing arm can rotate flexibly within a certain angle range, and the rotation angle is limited by an angle limiting device on cabinet 1. When the position of power board 9 needs to be adjusted, the operator only needs to manually rotate the swing arm to bring power board 9 to the appropriate position, and then fix the swing arm with the angle limiting device to complete the adjustment. This design makes the position adjustment of power board 9 more convenient and precise, better meeting different testing needs. At the same time, a stable connection structure is provided at the connection between the ball joint of power board 9 and the end of the swing arm to ensure that the connection between the ball joint of power board 9 and the swing arm will not loosen or fall off during the rotation of the swing arm, ensuring the stability and reliability of the test bench during use. Furthermore, to facilitate the operator's observation of the position adjustment of power board 9, an indicator is set inside cabinet 1 near the swing arm rotation area, allowing the operator to quickly and accurately adjust power board 9 to the required position according to the indicator. Furthermore, considering the differences in operating habits and strength among different operators, the operating force for rotating the swing arm is designed to be moderate. It is neither too heavy, causing operational difficulties, nor too light, making it prone to misoperation, thus further improving the convenience and comfort of operation. The position of the power board 9 should be adjusted to facilitate wiring and avoid lengthy and complex circuitry.

[0035] In some embodiments of the phase loss protector test bench provided in this application, please refer to... Figure 2 The swing arm includes a first connecting rod 11 and a second connecting rod 10. The first connecting rod 11 is connected to the ball joint of the inner wall of the cabinet 1, and the two ends of the second connecting rod 10 are connected to the power board 9 and the ball joint of the first connecting rod 11, respectively.

[0036] Specifically, when the angle of the power board 9 needs to be adjusted, the operator can hold the second connecting rod 10 and rotate it flexibly according to the actual needs. Since the first connecting rod 11 is connected to the ball joint of the inner wall of the cabinet 1, and the second connecting rod 10 is connected to the ball joint of the power board 9, this ball joint connection method allows the power board 9 to be precisely adjusted within multiple angle ranges. For example, when testing the phase loss protector at a specific angle, the power board 9 can be adjusted to the appropriate angle to ensure the accuracy and comprehensiveness of the test. Moreover, this multi-angle, different-position adjustment method greatly improves the flexibility and practicality of the phase loss protector test bench, adapting to various different test scenarios and needs. In actual operation, staff can easily and quickly adjust the angle of the power board 9 without complicated operating procedures, saving time and effort. At the same time, this design also ensures the stability of the power board 9 during the adjustment process, avoiding test errors caused by improper angle adjustment, thereby improving the reliability and accuracy of the entire phase loss protector test. The above settings enable multi-angle, different-position adjustment of the power board 9.

[0037] In some embodiments of the phase loss protector test bench provided in this application, please refer to... Figure 2 Cabinet 1 has a cabinet door 4 hinged to its back, away from the mounting plate 3. The control block 6 is installed and connected via the cabinet door 4.

[0038] Cabinet door 4 is connected to the back of cabinet 1 via hinges. The hinges are made of sturdy and durable material, ensuring smooth and stable opening and closing of cabinet door 4. After opening cabinet door 4, the internal space for installing control block 6 is clearly visible, with a reasonable layout and sufficient space reserved for operation and wiring. When installing control block 6, it needs to be precisely placed in the designated position and secured firmly using screws or other methods. The wiring process requires careful attention; the wiring of each component must be connected according to the designed route, ensuring a firm connection and good contact. This guarantees the normal operation of the phase-loss protector test bench, enabling accurate testing of the phase-loss protector and providing reliable testing support for power systems and related fields.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
