Description

Technical Field

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

[0002] After the indoor semi-solid circuit breaker is manufactured and assembled, it needs to undergo a break-in test. After the break-in, adjustments are made and the switch is tested. Only if the test is passed can it be shipped out of the factory.

[0003] Currently, the break-in of indoor semi-solid circuit breakers is carried out in a dedicated break-in mechanism box. This break-in mechanism box is large, heavy, and not flexible in movement. At the same time, the structure and wiring are also relatively complex, and it is difficult to repair it by oneself if it is damaged. The cost of manufacturing such a break-in mechanism box is also relatively high. If a variety of non-standard circuit breaker prototypes of different sizes are developed, it is obviously impossible to manufacture corresponding break-in equipment for each of these small and diverse prototypes, so as to avoid causing a lot of waste and loss. Utility Model Content

[0004] The purpose of this invention is to provide a circuit breaker break-in test vehicle to solve the break-in problems of circuit breakers and operating mechanisms in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A circuit breaker break-in test vehicle includes a break-in vehicle with a plate vertically connected to its surface. The plate has a circuit breaker to be tested and a mechanism for driving the circuit breaker installed on its two sides. The plate divides the break-in vehicle into a first section and a second section, the first section being larger than the second section. A dynamic fitting component is installed on the surface of the plate.

[0006] Preferably, the plate body includes supporting sheet metal parts, each with two core support components for the test vehicle. These supporting sheet metal parts are bent into rectangular structures with upward-facing openings. A main sheet metal block is fixed above the openings of the supporting sheet metal parts, and casters are installed at the bottom of each supporting sheet metal part. A reinforcing sheet metal part is fixed between the two supporting sheet metal parts. This reinforcing sheet metal part is welded and fixed between the two supporting sheet metal parts to balance and distribute the load of the main sheet metal block, effectively resisting external vertical loads (such as equipment weight, impact forces, etc.) and preventing deformation or breakage of the main sheet metal block due to single-point stress. Furthermore, the reinforcing sheet metal part welded between the two supporting sheet metal parts forms a frame structure through lateral connection, significantly improving overall torsional stiffness and lateral stability, and reducing the risk of structural instability caused by lateral forces (such as vibration, wind load). The combination of the supporting sheet metal parts and the reinforcing sheet metal parts forms a closed frame, significantly improving the structure's adaptability to complex working conditions.

[0007] Preferably, one side of the plate is symmetrically fixed with reinforcing ribs, which are located in the second section. The symmetrically arranged reinforcing ribs form bidirectional support, effectively resisting deformation of the plate in directions perpendicular to the ribs (such as lateral bending or torsion), significantly improving the structural bending and torsional stiffness. Simultaneously, the connection area between the reinforcing ribs and the plate forms a local rigid node, reducing localized depressions or warping caused by concentrated loads (such as point supports or impact forces), maintaining the plate's flatness. This ensures sufficient flatness for alignment and fit when installing the circuit breaker. The reinforcing ribs are fixed to the plate and the main sheet metal block by welding.

[0008] Preferably, the circuit breaker includes a hexagonal spindle and a main board. The circuit breaker is detachably installed in the first section. The hexagonal spindle is assembled with the moving mating part. The main board is the outer contour of the circuit breaker.

[0009] Preferably, one side of the plate is provided with a circuit breaker mounting stud, which faces the first section. The main plate surface has slots for accommodating the circuit breaker mounting stud. The circuit breaker mounting stud is for fitting the main plate of the circuit breaker, and the slots on the main plate are also necessary for subsequent installation on the cabinet. The circuit breaker mounting stud design further improves the stability of the circuit breaker on the break-in machine, thus reducing the likelihood of vibration-induced replacement during break-in testing. It also ensures that the circuit breaker will not cause vibration that could damage other components during testing. The circuit breaker mounting stud is welded to the plate.

[0010] Preferably, the other side of the plate is provided with a mechanism mounting stud, which faces the second section. The operating mechanism is also assembled by mating the transmission spindle with the moving mating part, and then locking the nut on the mechanism mounting stud.

[0011] Preferably, an operating mechanism is installed on one side of the plate, the operating mechanism is located in the second section, the operating mechanism has a transmission main shaft, and the transmission main shaft is installed with a moving mating part.

[0012] The technical solution of this utility model has the following beneficial effects: 1. The break-in cart is easy and flexible to move, with a simple structure, convenient installation, simple manufacturing cost, and compact size that saves space. It can be customized for various types of prototypes with small quantities of each type, avoiding significant space occupation and resource waste. Furthermore, when equipment needs to be moved to other locations for break-in, its small size, light weight, and swivel casters make transportation highly flexible. When certain carts are not needed, no large storage space is required. The break-in function is also perfectly achieved. Attached Figure Description

[0021] 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.

[0022] Example 1: Reference Figures 1-6 , A circuit breaker break-in test vehicle includes a break-in vehicle 10. A plate 102 is vertically connected to the surface of the break-in vehicle 10. A circuit breaker to be tested and a mechanism for driving the circuit breaker are respectively mounted on both sides of the plate 102. The plate 102 divides the break-in vehicle 10 into a first section 110 and a second section 111, where the first section 110 is larger than the second section 111. A dynamic fitting component 106 is mounted on the surface of the plate 102. An operating mechanism 202 is mounted on one side of the plate 102, located in the second section 111.

[0023] In the above scheme, the circuit breaker 20 undergoes mechanical operation and electrical performance tests under simulated actual operating conditions to verify its reliability and durability. The plate 102 has a rectangular structure, which can easily adapt to the shape of the circuit breaker 20. One side of the vertical plate 102 is used to install the circuit breaker 20, and the other side is used to install the mechanism that drives the circuit breaker to operate [also called the operating mechanism 202, which is responsible for converting external energy (such as human power, electromagnetic force, spring force, etc.) into mechanical motion to drive the contacts of the circuit breaker to complete the opening and closing operation]. Since the first interval 110 is larger than the second interval 111, it means that the plate 102 needs to be close to either the left or right side of the break-in vehicle 10 to form two intervals of different sizes. The larger interval is used to facilitate the installation of the circuit breaker 20, while the smaller interval is used to facilitate the installation of the operating mechanism 202. Figure 1 In this product, the first section 110 is on the left and the second section 111 is on the right. The positions of the first section 110 and the second section 111 can be interchanged (changing the position of the plate 102) without affecting the use of this test vehicle.

[0024] Reference in the preferred solution Figures 1-6 The break-in vehicle 10 includes a supporting sheet metal part 107. The supporting sheet metal part 107 has two core supporting parts for the test vehicle. The supporting sheet metal part 107 is bent into a rectangular structure. The opening of the supporting sheet metal part 107 faces upward. A sheet metal main block 108 is fixed above the opening of the supporting sheet metal part 107. The bottom of the supporting sheet metal part 107 is equipped with a moving wheel 101.

[0025] In the above scheme, the break-in vehicle 10 constitutes a complete support system. The two supporting sheet metal parts 107, combined with the moving wheels 101, provide a stable support effect. The bent supporting sheet metal parts 107 provide relatively good stable material strength. At the end of the bend, that is, with the opening facing upward, the supporting sheet metal parts 107 are fixed to the main sheet metal block 108. The main sheet metal block 108 functions to support the circuit breaker 20. The moving wheels 101 are connected to the bottom of the supporting sheet metal parts 107 by bolt positioning. Here, the supporting sheet metal parts 107 and the main sheet metal block 108 are fixed by welding, thereby improving the overall structural stability.

[0026] Preferred reference Figure 1 A reinforcing sheet metal part 109 is fixed between the two supporting sheet metal parts 107.

[0027] In this preferred embodiment, the reinforcing sheet metal part 109 is welded and fixed between the two supporting sheet metal parts 107 to balance and distribute the load of the main sheet metal block 108, effectively resisting external vertical loads (such as equipment weight, impact force, etc.) and preventing the main sheet metal block 108 from deforming or breaking due to single-point stress. Furthermore, the reinforcing sheet metal part 109 welded between the two supporting sheet metal parts 107 forms a frame structure through lateral connection, significantly improving the overall torsional stiffness and lateral stability, and reducing the risk of structural instability caused by lateral forces (such as vibration, wind load). The combination of the supporting sheet metal parts 107 and the reinforcing sheet metal part 109 forms a closed frame, significantly improving the structure's resilience to complex working conditions. The caster wheel 101 is preferably a swivel wheel, which gives the break-in vehicle 10 good steering function, and the swivel wheel has a self-locking function.

[0028] Preferred reference Figures 2-5 One side of the plate 102 is symmetrically fixed with a reinforcing rib plate 105, which is located in the second interval 111.

[0029] In this preferred embodiment, the symmetrically arranged reinforcing ribs 105 form a bidirectional support, effectively resisting the deformation of the plate 102 in the direction perpendicular to the ribs (such as lateral bending or torsion), significantly improving the structural bending and torsional stiffness. Simultaneously, the connection area between the reinforcing ribs 105 and the plate 102 forms a local rigid node, reducing local dents or warping caused by concentrated loads (such as point supports or impact forces), maintaining the flatness of the plate 102. This ensures sufficient flatness for alignment and fit when installing the circuit breaker 20. The reinforcing ribs 105 are fixed to the plate 102 and the sheet metal main block 108 by welding.

[0030] refer to Figure 5 and Figure 6 The circuit breaker 20 includes a hexagonal spindle 201 and a main board 204. The circuit breaker 20 is detachably installed in the first section 110. The hexagonal spindle 201 is assembled with the moving mating part 106, and the main board 204 is the outer contour of the circuit breaker 20. The operating mechanism 202 contains a transmission spindle 203, which is installed with the moving mating part 106.

[0031] In the above scheme, the main board 204 is the conventional housing structure of the circuit breaker 20. When this device is tested, the circuit breaker 20 body to be run-in is transported to the run-in vehicle 10 (in the first section 110) and placed on the sheet metal main block 108 with the hexagonal spindle 201 facing upward. The circuit breaker 20 on the sheet metal main block 108 is moved and adjusted so that the main board 204 is attached to one side of the plate 102. Here, the position of the hexagonal spindle 201 needs to be concentrically matched with the moving mating part 106 so that the hexagonal spindle 201 and the moving mating part 106 are assembled together. It should be noted that the moving fitting 106 of this invention is commercially available. Here, the moving fitting 106 refers to a bearing component. The moving fitting 106 can rotate freely on the plate 102, and both ends of the moving fitting 106 have hexagonal slots. That is, the hexagonal main shaft 201 of the circuit breaker 20 and the transmission main shaft 203 (hexagonal shape) of the operating mechanism 202 are respectively located at both ends of the moving fitting 106, achieving linkage through the moving fitting 106. Figure 2 In this design, the moving mating part 106 features a raised "I" shape, which corresponds to the transmission main shaft 203 of the operating mechanism 202 needing to engage with this raised "I". Regardless of the connection method, the purpose is to synchronize the rotation of the transmission main shaft 203 and the hexagonal main shaft 201. The structural characteristics of the moving mating part 106 do not affect the realization of this product. Specifically, during the design process, different types of moving mating parts 106 need to be selected according to the corresponding circuit breaker 20 model; since the hexagonal main shaft 201 models of circuit breakers 20 on the market all adopt a hexagonal structure, the moving mating part 106 can be used for break-in tests in accordance with the connection and assembly of mainstream circuit breakers 20 on the market.

[0032] Preferred reference Figures 1-6 One side of the board 102 is provided with a circuit breaker mounting stud 103, which faces the first interval 110. The surface of the main board 204 has a slot for cooperating with the circuit breaker mounting stud 103.

[0033] In the preferred embodiment, the circuit breaker mounting stud 103 is designed to fit the main board 204 of the circuit breaker 20, and the holes on the main board 204 are also necessary slots for subsequent installation on the cabinet. The installation of the circuit breaker mounting stud 103 further improves the stability of the circuit breaker 20 on the break-in machine 10, thus preventing the circuit breaker 20 from vibrating and requiring replacement during break-in testing. This also ensures that the circuit breaker 20 will not cause vibration that could damage other components during testing. The circuit breaker mounting stud 103 is welded to the plate 102. The figure shows five circuit breaker mounting studs 103, but the specific number is not limited by the drawing. A nut is rotated and tightened around the circuit breaker mounting stud 103 to complete the reinforced installation of the circuit breaker 20.

[0034] Preferred reference Figure 5 and Figure 6 On the other side of the plate 102, there is a mechanism mounting stud 104, which faces the second section 111.

[0035] In the preferred embodiment, the mechanism mounting studs 104 are also welded to the plate 102. In the figure, the number of mechanism mounting studs 104 is shown as four (reference). Figure 2The specific quantity is not limited by the drawing. Similarly, the operating mechanism 202 also involves fitting the transmission main shaft 203 onto the moving fitting part 106, and then tightening the nut on the mechanism mounting stud 104 to complete the assembly of the operating mechanism 202.

[0036] In summary, the break-in cart 10 is easy to move and flexible, has a simple structure, is easy to install, is simple to manufacture and has low cost. It is compact, flexible and does not take up much space. The break-in cart 10 can be made for a variety of prototypes with a small number of each type, avoiding large space occupation and resource waste.

[0037] The specific implementation process of this utility model is as follows: Step 1: Move the break-in vehicle 10 into the test chamber, and transport and install the circuit breaker 20 and operating mechanism 202 to be tested on the break-in vehicle 10; Step 2: Connect the power supply to the operating mechanism 202 and begin the break-in process; Step 3: After the break-in period is complete, disassemble the circuit breaker 20 and the operating mechanism 202; reinstall the circuit breaker 20 and the operating mechanism 202 to be tested.

The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection.
