Abstract
Description
Technical Field
[0001] This application relates to the technical field of electrical equipment testing, and in particular to a multifunctional pole-mounted circuit breaker isolating contact testing device. Background Technology
[0002] Isolating contacts, also known as pole-mounted circuit breakers, can promptly disconnect the circuit in the event of overload, short circuit, or other faults, ensuring the safety and stability of the power supply. Testing devices typically refer to a method used in power systems, especially high-voltage or medium-voltage switchgear, to verify whether the isolating contacts can open or close correctly.
[0003] A related patent document, Chinese Patent No. CN209044024U, discloses a circuit breaker testing device. A test main board is mounted on a slide rail and can move back and forth along the rail. The test main board has multiple test blocks, each containing a test contact. A motor starts the test main board, moving it forward along the slide rail until the test contact contacts the circuit breaker terminals. Once the test contact contacts the circuit breaker terminals, current is transmitted through the test contact to the circuit breaker for electrical performance testing, including opening and closing tests. The test blocks are fixed to the test main board and have through holes extending outwards for mounting the test contacts and checking if they are within acceptable limits. Spring supports and contact springs are located in the through holes of the test blocks, and these supports and springs can accommodate test contacts with small size differences. However, this testing method has significant drawbacks. The testing device integrates multiple functions and uses a motor drive system, making the overall structure complex and potentially leading to higher manufacturing and maintenance costs. Because the device relies on the coordinated operation of multiple electronic components (such as processors, contact springs, spring supports, etc.), the failure of any component may affect the reliability and accuracy of the entire system.

[0032] The following combination Figures 1 to 3 This application will be described in further detail.
[0033] This application provides a multifunctional pole-mounted circuit breaker isolating contact detection device.
[0034] Reference Figure 1 and Figure 2 , the detection device is composed of a detection table 1, a partition board 2, a reinforcing board 3, a fixing board 4, a detection block 5, a first elevation block 6 and a second elevation block 7. The isolation contact is composed of an isolation crank arm 01, an isolation connecting plate 02, an isolation slider 03, an isolation insulating pull rod 04 and an isolation connecting shaft 05.
[0035] Reference Figure 1 and Figure 2 , the detection table 1 is fixedly connected above the transfer cart 8 through the fixing board 4. The first elevation block 6 and the second elevation block 7 are arranged at intervals on the detection table 1 and on one side of the detection block 5. The notch 501 provided on the detection block 5 can detect the isolation insulating pull rod 04. The notch 501 can detect the manufacturing tolerance of the isolation insulating pull rod 04. The width of the detection block 5 and the height of the notch 501 are about 25 mm - 30 mm, and can also be specifically 27 mm. There is a specified interval distance between each detection block 5, and it is avoided that the isolation contacts collide with each other and scratch the surface of the detected object during the detection process. Each detection block 5 is spaced 130 mm - 140 mm apart, and the detection block 5 is arranged at intervals with the side plate 102 and is spaced 60 mm - 70 mm apart. During the manufacturing process of each isolation insulating pull rod 04, there are tolerances, so it is qualified to snap the small end of the isolation insulating pull rod 04 into the notch 501 of the detection block 5. A plurality of groups of support plates 9 are equidistantly arranged in the vertical direction of the transfer cart 8. The isolation contact can be placed on the support plate 9 through the rhombic rod 12. Such a structural design enables the detection and storage of the isolation contact to be completed on the same device, avoiding additional handling operations, improving production efficiency, and at the same time reducing the risk of damage to the isolation contact during the handling process. Reference Figure 2 , the detection table 1 includes a bottom plate 101 and a side plate 102. Side plates 102 are provided above three sides of the bottom plate 101. This design can play a certain protective role for the components placed on the detection table 1 and prevent them from slipping. A partition board 2 is fixedly connected in the middle above the bottom plate 101, and the partition board 2 is fixedly installed on the other side of the detection block 5. The partition board 2 can divide the detection table 1 into different areas, facilitating the orderly placement and detection of the components related to the isolation contact. The bottom plate 101 is generally made of a metal material, such as a steel plate, which has good strength and stability; the side plate 102 can also be made of a metal material and is fixed to the bottom plate 101 by welding or bolt connection. Here, the bottom plate 101 can also be made of a high-strength engineering plastic material, which is lighter in weight and has certain corrosion resistance. Reference Figure 3A number of detection blocks 5 are evenly spaced above the detection table 1, with the detection blocks 5 located in the center of the detection table 1. Each detection block 5 has a slot 501 on one side. The closed section of the slot 501 is an arc-shaped surface 502, and the upper and lower parts of the open end are rounded 503. The arc-shaped surface 502 and the rounded edges 503 allow the insulating pull rod 04 to be inserted into the slot 501 more smoothly. The arc-shaped surface 502 is designed to fit the cylindrical shape of one side of the insulating pull rod 04, which reduces wear and impact. The detection blocks 5 are generally made of a high-hardness metal material, such as stainless steel, to ensure that they will not deform during long-term use. Of course, the detection blocks 5 can also be made of hard alloy material, which has better wear resistance. The size and shape of the slot 501 are designed according to the shape of the insulating pull rod 04 to ensure accurate detection of its assembly precision. (Reference) Figure 1 and Figure 2 Several reinforcing plates 3 are provided, and each is fixedly connected at equal intervals to the corresponding surfaces of one side plate 102 and the partition plate 2. The reinforcing plates 3 enhance the overall structural strength of the testing table 1 and prevent deformation during use. The reinforcing plates 3 are typically made of thin metal sheets and are fixed to the side plate 102 and the partition plate 2 by welding or bolting. Fixing plates 4 are provided on both sides below the base plate 101, and these fixing plates 4 are used to fix the testing table 1 to the transfer cart 8. (Reference) Figure 1 and Figure 2 The first shim 6 and the second shim 7 are spaced apart on one side of the detection block 5, with the first shim 6 being lower in height than the second shim 7. The first shim 6 and the second shim 7 are used to place different parts of the isolating connecting shaft 05 and the isolating insulating rod 04. By setting the height difference, the actual assembly state of the isolating contact can be simulated, thereby accurately detecting its assembly accuracy. The first shim 6 and the second shim 7 are generally made of plastic, rubber, or wood, providing a certain degree of cushioning to prevent damage to the isolating contact components. They can also be made of metal with a layer of plastic material on top. (Reference) Figure 1 and Figure 2 The transfer cart 8 consists of a vertical rod 801, an upper horizontal rod 802, a lower horizontal rod 803, and a reinforcing rod 804. The upper horizontal rod 802 and lower horizontal rod 803 are respectively positioned above and below the vertical rod 801, and the lower horizontal rod 803 is connected to the vertical rod 801 via the reinforcing rod 804. This structural design gives the transfer cart 8 good stability and load-bearing capacity. The upper horizontal rod 802, lower horizontal rod 803, and reinforcing rod 804 are fixedly connected to the vertical rod 801 by triangular stiffeners 10, which enhance the strength of the connection and prevent loosening during transfer. The components of the transfer cart 8 are generally made of metal tubing, such as steel pipe, which has high strength. Alternatively, aluminum alloy tubing can be used, which is lighter. (Reference) Figure 1 and Figure 2A testing platform 1 is fixedly connected to the top of the transfer cart 8. Several sets of support plates 9 are evenly spaced vertically on the transfer cart 8, with two plates in each set, each fixedly connected to the transfer cart 8. The support plates 9 are used to hold the rhomboid rods 12 and the isolation crank arms 01 fitted on them. Each set of two plates is evenly spaced along the height of the vertical rod 801. Each support plate 9 has anti-slip strips 901 on both sides to prevent the rhomboid rods 12 from slipping. Casters 11 are provided on both sides below the reinforcing rod 804, facilitating the movement of the transfer cart 8 and improving operational flexibility. The support plates 9 are generally made of metal sheet and are connected to the transfer cart 8 by welding or bolting. The casters 11 can be equipped with brakes for easy securing of the transfer cart 8 when needed. (Reference) Figure 1 and Figure 2 A plurality of isolation crank arms 01 are evenly spaced on the prismatic rod 12. The prismatic rod 12 is placed above each set of support plates 9. One side of the isolation insulating pull rod 04 is placed in the slot 501, and the other side is placed in the first shim block 6. The isolation connecting shaft 05 is placed in the second shim block 7. By placing these isolation contact components on the testing device in a specific manner, their assembly accuracy can be tested, and a storage function is also achieved. The implementation principle of this embodiment is as follows: by reasonably setting the testing block 5, the first shim block 6, the second shim block 7, and the support plate 9, the assembly accuracy of the isolation contact can be accurately tested, and the relevant components can be stored in an orderly manner. The testing block 5 has a slot 501 on one side, and the size and shape of the arc surface 502 on the slot 501 are designed according to the shape of the isolation insulating pull rod 04. The first shim block 6 and the second shim block 7 are to prevent the isolation contact from being suspended. A number of isolation crank arms 01 are fitted onto the prismatic rod 12. The other side of the isolation insulating pull rod 04 is placed on the first raised block 6, and the isolation connecting shaft 05 is placed on the second raised block 7. The isolation insulating pull rod 04 is placed in the slot 501 for testing. After the isolation contact is tested, the isolation contact is placed above each set of support plates 9 via the prismatic rod 12. The support plates 9 are set on the transfer cart 8. The setting of the transfer cart 8 allows the entire device to move flexibly, realizing the orderly placement and storage of the pole-mounted circuit breaker isolation contact-related components, which is convenient for subsequent transfer to the next process assembly. This design not only improves production efficiency and reduces labor and time costs, but also reduces the risk of damage to the isolation contact during handling, ensuring product quality and making a significant improvement and contribution to existing technology.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
