Description

Technical Field

[0001] This utility model belongs to the field of test vehicle technology, specifically relating to a circuit breaker transfer test vehicle. Background Technology

[0002] After the indoor environmentally friendly circuit breakers are manufactured and undergo circuit resistance and mechanical characteristic tests on the production line, they need to be taken to a specialized laboratory for withstand voltage and partial discharge tests.

[0003] Currently, after the mechanical characteristic test, the indoor environmental protection circuit breakers need to be lifted onto a tray and then forklifted to the withstand voltage partial discharge chamber. Then, one switch on the tray needs to be lifted onto a special withstand voltage partial discharge insulating tray for testing. After one switch is completed, it needs to be removed before the next switch can be lifted for testing. Only one switch can be tested at a time. This wastes both effort and time, resulting in low testing efficiency and affecting the progress. Utility Model Content

[0004] The purpose of this invention is to provide a circuit breaker transport test vehicle to solve the efficiency problem of withstand voltage partial discharge test in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A circuit breaker transport test vehicle includes a loading vehicle group on which circuit breakers are placed for withstand voltage and partial discharge tests. The loading vehicle group includes a test trolley and a transport trolley, the transport trolley being used for transporting the circuit breakers. The test trolley and the transport trolley are combined and spliced ​​together to form the loading vehicle group.

[0006] Preferably, the loading vehicle is divided into an upper aluminum profile frame and a lower aluminum profile frame, with several insulating supports installed between the upper and lower aluminum profile frames. A load-bearing plate is fixed to the surface of the upper aluminum profile frame, the circuit breaker is placed on the surface of the load-bearing plate, and casters are installed at the bottom of the lower aluminum profile frame.

[0007] Preferably, both the upper aluminum profile frame and the lower aluminum profile frame include long-side aluminum profiles and short-side aluminum profiles, which are assembled into a rectangular aluminum profile frame.

[0008] Preferably, a handle is detachably mounted on the short-side aluminum profile, and a locking block is provided at the bottom of the handle, which is then engaged with the short-side aluminum profile. The handle needs to be removed during the withstand voltage partial discharge test; therefore, the detachable design of the handle facilitates switching between the withstand voltage partial discharge test and the mobile trolley.

[0009] Preferably, the locking block has a U-shaped structure, and it engages with the short-side aluminum profile through the U-shaped opening. The U-shaped structure of the locking block can match the thickness of the short-side aluminum profile. When removing the handle, lifting the handle upwards will disengage the locking block from the short-side aluminum profile; similarly, when installing the handle, simply insert the locking block into the short-side aluminum profile. This design is practical, convenient, and easy to switch between.

[0010] Preferably, when the transfer trolley transports circuit breakers, the circuit breakers are placed close together in pairs. Transporting circuit breakers by the transfer trolley requires placing the circuit breakers close together to accommodate more circuit breakers. In actual use, this transfer trolley can transport five circuit breakers at a time.

[0011] Preferably, during withstand voltage and partial discharge tests, the circuit breakers on the loading trolley are separated from each other in pairs. The transfer trolley moves close to the test trolley to form a loading trolley. By moving two circuit breakers on the test trolley, the circuit breakers on the transfer trolley are separated, creating a certain interval between them to ensure sufficient test distance and prevent mutual interference between the two.

[0012] Preferably, the insulating support is provided on both the long and short aluminum profiles. The insulating support is used to reinforce the connection between the upper and lower aluminum profile frames, and at the same time, it can increase the creepage distance and improve safety performance during testing.

[0013] The technical solution of this utility model has the following beneficial effects: 1. The transfer trolley is positioned next to the mechanical characteristic test on the production line. It waits for the circuit breaker switches to flow in (assembly line transport), then moves multiple incoming circuit breaker switches onto the transfer trolley. The trolley is then pulled into the withstand voltage and partial discharge chamber and joined to the test trolley. Subsequently, the circuit breakers on the transfer trolley are moved, and some are placed on the test trolley for random withstand voltage and partial discharge tests. This loading trolley group performs both transfer and testing functions.

[0014] 2. The insulating support can increase the distance between the upper aluminum profile frame and the lower aluminum profile frame. The insulating support can ensure the ground insulation distance during the test (the circuit breaker switch has sufficient insulation distance from the ground during the test to meet the withstand voltage test requirements).

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] Example 1: refer to Figures 1-7 A circuit breaker transport test vehicle includes a loading vehicle group 10 on which a circuit breaker 101 is placed for withstand voltage and partial discharge tests. The loading vehicle group 10 includes a test trolley 20 and a transport trolley 30, which is used for transporting the circuit breaker 101. The test trolley 20 and the transport trolley 30 are combined and spliced ​​together to form the loading vehicle group 10.

[0026] In the above scheme, withstand voltage testing and partial discharge testing are important means to evaluate the insulation performance of electrical equipment (such as circuit breaker 101). In the withstand voltage test: it verifies whether the insulation structure of the electrical equipment will experience insulation faults such as breakdown or flashover when the voltage is higher than the rated voltage for a period of time, ensuring the equipment can operate safely under possible overvoltage conditions; in the partial discharge test: it detects whether there is partial discharge in the internal insulation of the electrical equipment, because partial discharge is an early sign of insulation degradation, and timely detection and treatment can prevent the further development of insulation faults. The test trolley 20 and the transfer trolley 30 are combined and spliced ​​together to form the loading vehicle group 10. Here, "splicing" is explained as follows: The test trolley 20 and the transfer trolley 30 are brought close together to form a shape like... Figure 1 and Figure 2 The shape within the frame requires no other connecting structures and can be combined and disassembled at any time; In actual use, the test trolley 20 is placed stationary in the withstand voltage partial discharge chamber (this does not mean it cannot be moved), while the transfer trolley 30 is placed next to the mechanical characteristic test on the production line, waiting for the circuit breaker 101 switches to flow in (assembly line transport). Multiple circuit breaker 101 switches that flow in are moved onto the transfer trolley 30, and the transfer trolley 30 is pulled into the withstand voltage partial discharge chamber and brought close to the test trolley 20 for splicing. Then, the circuit breakers 101 on the transfer trolley 30 are moved, and some of the circuit breakers 101 are placed on the test trolley 20, and withstand voltage and partial discharge tests are started randomly. The design length of the test trolley 20 is 1.1 meters, the design length of the transfer trolley 30 is 1.8 meters, and the length of the loading trolley 10 is the sum of the length of the test trolley 20 and the length of the transfer trolley 30, which is 2.9 meters.

[0027] Preferred reference Figure 1 and Figure 2 The loading vehicle group 10 is divided into an upper aluminum profile frame 60 and a lower aluminum profile frame 50. Several insulating supports 90 are installed between the upper aluminum profile frame 60 and the lower aluminum profile frame 50. A load-bearing plate 601 is fixed on the surface of the upper aluminum profile frame 60. The circuit breaker 101 is placed on the surface of the load-bearing plate 601. A moving wheel 901 is installed at the bottom of the lower aluminum profile frame 50.

[0028] In the preferred embodiment, the loading vehicle group 10 is divided into an upper aluminum profile frame 60 and a lower aluminum profile frame 50. This means that the test trolley 20 and the transfer trolley 30 are also composed of the upper aluminum profile frame 60 and the lower aluminum profile frame 50. The lower aluminum profile frame 50 is supported by casters 901. The casters 901 are preferably omnidirectional wheels, which provide convenient steering and are selected to have a locking function, which can be used to easily stabilize the current position of the test trolley 20 and the transfer trolley 30. The insulating support 90 can increase the distance between the upper aluminum profile frame 60 and the lower aluminum profile frame 50. The insulating support 90 can ensure the ground insulation distance during the test (the circuit breaker 101 switch has sufficient insulation distance from the ground during the test to meet the withstand voltage test requirements). This loading vehicle group 10 is used for both transfer and testing.

[0029] Further reference Figure 1 and Figure 2Both the upper aluminum profile frame 60 and the lower aluminum profile frame 50 include long-side aluminum profiles 70 and short-side aluminum profiles 80, which are assembled into a rectangular aluminum profile frame.

[0030] In a further implementation scheme, the long-side aluminum profile 70 and the short-side aluminum profile 80 form a rectangular frame. The rectangular structure can increase the number of circuit breakers 101 that can be placed, thereby facilitating the simultaneous transport of multiple circuit breakers 101 by the transfer trolley 30. The combined transfer trolley 30 and test trolley 20 can provide a longer distance, so that each circuit breaker 101 undergoing withstand voltage partial discharge test can be separated from each other by a certain distance, ensuring sufficient test distance between each pair of circuit breaker 101 switches.

[0031] Preferred reference Figure 3 A handle 40 is detachably installed on the short side aluminum profile 80. The bottom of the handle 40 is provided with a locking block 401, and the handle 40 is locked onto the short side aluminum profile 80 through the locking block 401. The locking block 401 has a U-shaped structure and is locked onto the short side aluminum profile 80 through the U-shaped opening.

[0032] In the preferred embodiment, the handle 40 needs to be removed during the withstand voltage partial discharge test. Therefore, the handle 40 is designed to be detachable to facilitate switching between the withstand voltage partial discharge test and the mobile carriage. The U-shaped structure of the locking block 401 can match the thickness of the short side aluminum profile 80. When removing the handle 40, lift the handle 40 upwards, and the locking block 401 will disengage from the short side aluminum profile 80. Similarly, when installing the handle 40, simply insert the locking block 401 into the short side aluminum profile 80. This design is practical, convenient, and easy to use.

[0033] Preferred reference Figure 6 When the transfer trolley 30 transports the circuit breaker 101, the circuit breakers 101 in pairs move closer to each other.

[0034] In the preferred embodiment, transporting circuit breakers 101 by the transfer trolley 30 requires placing the circuit breakers 101 close together to accommodate more circuit breakers 101. In actual use, the transfer trolley 30 can transport five circuit breakers 101 at a time (see reference). Figure 6 ).

[0035] Preferred reference Figure 7 During the withstand voltage and partial discharge tests, the circuit breakers 101 on the loading vehicle group 10 are separated from each other in pairs.

[0036] The transfer trolley 30 moves closer to the test trolley 20 to form a loading vehicle group 10. It moves two circuit breakers 101 on the test trolley 20 and at the same time separates the circuit breakers 101 on the transfer trolley 30, so that there is a certain interval between them, ensuring sufficient test distance and keeping the two from interfering with each other.

[0037] Further reference Figure 2 Insulating support 90 is provided on both the long side aluminum profile 70 and the short side aluminum profile 80.

[0038] In a further implementation scheme, the insulating support 90 is used to reinforce the connection between the upper aluminum profile frame 60 and the lower aluminum profile frame 50. At the same time, the insulating support 90 can increase the creepage distance and improve the safety performance during the testing process.

[0039] The specific implementation process of this utility model is as follows: The steps are as follows: 1. Place the 1.1-meter test trolley 20 in the withstand voltage partial discharge chamber and leave it stationary.

[0040] 2. Place the 1.8-meter transfer trolley 30 next to the mechanical characteristic test of the production line and wait for the switch to flow in.

[0041] 3. After loading five units onto the 1.8-meter transfer trolley 30, pull it to the withstand voltage partial discharge room and assemble it with the 1.1-meter test trolley 20. Move the two circuit breaker 101 switches on the 1.8-meter transfer trolley 30 onto the 1.1-meter test trolley 20, and increase the distance between the other switches to ensure sufficient test distance.

[0042] Four or five switches were tested together for withstand voltage partial discharge.

[0043] 5. After the test is completed, remove the switch and pack it up, then pull the empty car back to the production line.

[0044] Working principle: The transfer trolley 30 is placed next to the mechanical characteristic test on the production line. After one switch is completed, it is directly lifted onto the trolley. After five switches are loaded, they are directly pulled to the withstand voltage partial discharge room. There is no need to move the switches to the special withstand voltage partial discharge insulating tray. Just increase the spacing between the switches, and the test can be carried out directly. Five switches can be tested at the same time. After the test is completed, the switches are unloaded, packed, and the empty trolley is pulled back to the mechanical characteristic test room to wait for the next batch.
