Description

Technical Field

[0002] A double-break integrated leakage circuit breaker is a leakage protection device with a dual-break contact structure, integrating leakage protection and circuit-breaking functions. It typically uses a dual-break design to improve interrupting capacity and safety. Generally, double-break integrated leakage circuit breakers must be tested on the production line for leakage protection performance before shipment. Therefore, this performance testing is a crucial step in ensuring the qualified delivery of finished products.

[0003] The prior art discloses a Chinese patent with publication number CN 110911248 B: a leakage circuit breaker, and discloses a contact unit and a trip unit. By pressing a test button, it is observed that the leakage circuit breaker can trip normally without causing the circuit board, leakage trip coil, etc. in the leakage circuit breaker to burn.

[0004] However, the above-mentioned prior art still has certain defects, that is, during use, the leakage circuit breaker adopts a single breaking point structure design. The current that increases at the moment of fault occurrence is likely to increase the short-circuit current pressure borne by a single contact, thereby reducing its breaking capacity.

The circuit breaker is judged to be qualified by detecting whether the electrode head is on and off and monitoring the time when the circuit breaker is tripped.

[0006] However, the above-mentioned prior art still has certain defects, that is, during use, the tripping time of the circuit breaker is detected by switching the current gear, and the circuit breaker position needs to be switched by rotating the material moving device, which reduces the test efficiency.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] The leakage circuit breaker detector of the present invention belongs to a type of equipment for measuring electrical variables and is mainly used for testing the leakage protection performance of the leakage circuit breaker to ensure electricity safety.

[0023] The leakage circuit breaker of the present invention belongs to a type of low-voltage electrical appliance in the power equipment manufacturing industry and is a key device for electrical safety. It is mainly used in low-voltage power distribution systems to prevent electric shock accidents and electrical fires caused by leakage.

[0024] The PVD coating preparation device for cemented carbide cutting tools of the present invention is mainly used for Example 1: Refer to the attached instructions Figure 1-Figure 2 This embodiment is the first embodiment of the present invention, which provides a double-breakpoint integrated leakage circuit breaker, including: The housing 1, the incoming line port 2 and the outgoing line port 3 are respectively arranged at both ends of the housing 1, and the zero-sequence current transformer, the leakage tripping device, the arc extinguishing device and the contact system are all installed inside the housing 1, wherein the zero-sequence current transformer, the leakage tripping device, the arc extinguishing device and the contact system are all conventional components in the leakage circuit breaker, and can be arranged according to the arrangement method of the existing circuit breaker. The specific structure is not described here in conjunction with the accompanying drawings. At the same time, the specific working principle of the leakage circuit breaker can refer to the working principle of the existing circuit breaker, which is also not described here. Furthermore, the contact system in the leakage circuit breaker includes two groups of moving and static contacts, and two rocker arms 6 are provided inside the shell 1 for moving the moving contacts in the contact system to make contact with the static contacts to open the leakage circuit breaker. The linkage shaft 5 is used to fixedly connect the two rocker arms 6. The operating handle 4 is fixedly sleeved on the middle part of the outer side of the linkage shaft 5, and the operating handle 4 is rotatably embedded in the shell 1. By moving the operating handle 4, the linkage shaft 5 is rotated, thereby driving the two rocker arms 6 to swing synchronously, so that the swinging rocker arms 6 are used to move the moving contacts and static contacts at corresponding positions in the contact system to make contact to open the leakage circuit breaker.

[0025] It should be noted that the contact system in the leakage circuit breaker of the present invention adopts a double-breakpoint structure design, that is, two pairs of contacts work in series, so that when a circuit fault occurs, the two contacts are separated at the same time to cut off the power supply. The double-breakpoint structure design can generate two series arcs at the moment the moving contacts are separated, effectively reducing the short-circuit current pressure borne by a single contact and improving the breaking capacity.

[0026] Example 2: Refer to the attached instructions Figure 3-Figure 4 and Figure 6 This embodiment is the second embodiment of the present invention, which provides a double-breakpoint integrated leakage circuit breaker detection machine, including: The chassis 11 and the partition frame 10 are fixedly arranged inside the chassis 11. The partition frame 10 is used to divide the interior of the chassis 11 into a detection area and a lifting area. A partition bar 12 is fixedly provided at the top middle portion of the partition frame 10. A channel groove 13 is opened through the chassis 11 at a position corresponding to the lifting area. A conveyor belt 14 for transporting the leakage circuit breaker to the designated workstation is arranged inside the channel groove 13. The pushing assembly 81 is mounted on the top of the partition frame 10, the detecting assembly 82 is mounted on the pushing end of the pushing assembly 81, and the toggle assembly 83 for toggling the operating handle 4 is mounted on the pushing assembly 81. The pushing assembly 81, the detecting assembly 82 and the toggle assembly 83 together constitute a testing mechanism 8. The testing mechanism 8 is provided with two groups, and the two groups of testing mechanisms 8 are respectively placed on both sides of the partition bar 12; A sample frame 71 is provided between the two track frames 812 fixed on the top of the pad frame 811, and the alignment component 72 is provided between one of the detection components 82 and the sample frame 71. The sample frame 71 and the alignment component 72 together constitute a comparison mechanism 7 for detecting the leakage circuit breaker pushed to the test station.

[0027] It should be noted that, in the present invention, after the assembled leakage circuit breakers are stacked on the conveyor belt 14 in sequence, they are sent to the detection area inside the chassis 11 by using the conveyor belt 14, and in the process of pushing the detection component 82 to the test site by using the pushing component 81, the cooperation of the sample frame 71 and the alignment component 72 is used to align and limit the lifted leakage circuit breaker to be tested, and then the toggle component 83 is used to toggle the operating handle 4 so that the moving contact and the static contact at the corresponding position in the contact system come into contact to open the leakage circuit breaker, and then the leakage detection is turned on by using the detection component 82. The qualification of the leakage circuit breaker is determined by observing whether the operating handle 4 in the open state trips and resets under the action of a constant current.

[0028] Furthermore, if Figure 6 As shown, the pushing assembly 81 includes a pad frame 811 fixedly mounted on the top of the partition frame 10. The pad frame 811 and the partition frame 10 are detachably mounted by locking bolts, which is convenient for disassembly and assembly and facilitates later operation and maintenance. Track frames 812 are fixed on both sides of the top of the pad frame 811, and mounting frames 814 are fixed at both ends of the top of the pad frame 811. Cylinders 815 are fixedly mounted on opposite sides of the two mounting frames 814, and the telescopic ends of the two cylinders 815 are fixedly connected to slides 813 that are slidably mounted between the two track frames 812. Among them, there are two detection assemblies 82, which are respectively mounted on the two slides 813, while there is only one toggle assembly 83, which is mounted on one of the slides 813 and moves along the track frame 812 together with the corresponding detection assembly 82.

[0029] It should be noted that after the leakage circuit breaker to be tested is sent to the test station, two cylinders 815 are used to push the corresponding slide 813 to move toward each other along the track frame 812, thereby driving the two detection components 82 to move toward each other synchronously, so that the test ends on the two detection components 82 are respectively inserted into the input port 2 and the output port 3 on the leakage circuit breaker, waiting for testing.

[0030] Furthermore, if Figure 6-Figure 8 As shown, the detection assembly 82 includes a lifting plate 821 provided at the bottom of the corresponding slide 813 and a second cylinder 822 fixed to the top of the corresponding slide 813. The telescopic end of the second cylinder 822 passes through the slide 813 and is fixedly connected to the lifting plate 821. A guide column 1 that movably passes through the slide 813 is fixed on the top of the lifting plate 821 to guide and limit the lifting process of the lifting plate 821. The detection assembly 82 also includes a J-shaped plate 824 fixed to the two ends of the bottom of the corresponding slide 813. A test frame 823 is fixedly connected between the other ends of the two J-shaped plates 824. The test frame 823 is hollow, and a wire 828 and a test pole 829 are fixedly installed on both sides of the test frame 823. The ends of the wire 828 and the test pole 829 extending into the interior of the test frame 823 are fixedly connected to a docking terminal. The docking terminal is fixed to the side wall of the interior of the test frame 823. Since the position of the test frame 823 is fixed relative to the slide 813, it can be ensured that the test pole 829 is always on a horizontal plane at a constant height. A conducting component for controlling the on and off of the two docking terminal posts is provided between the lifting plate 821 and the test frame 823. The conducting component includes a horizontal plate 1 825 fixedly connected to the lifting plate 821 and an insertion strip 827 fixed at the bottom of the horizontal plate 1 825. The bottom end of the insertion strip 827 is movably inserted into the inside of the test frame 823, wherein the top of the horizontal plate 1 825 is fixedly connected to the horizontal plate 2 826. Two groups of guide posts 2 that movably pass through the horizontal plate 1 825 and the horizontal plate 2 826 are fixed on the top of the test frame 823. The two groups of guide posts are placed on both sides of the insertion strip 827. Conductive parts are provided at the bottom end of the insertion strip 827 corresponding to the position of each group of docking terminal posts. When testing is required, it is only necessary to conduct the connection between the connecting wire 828 and the two docking terminal posts of the test pole 829 through the conductive parts.

[0031] It should be noted that, during the process of testing the leakage protection performance of the leakage circuit breaker to be tested that is sent to the test station, the slide 813 is pushed along the track frame 812 by the cylinder 1 815, and the detection component 82 is in the process of synchronous movement with the corresponding slide 813. The test pole 829 remains in the state of facing the corresponding wiring port on the leakage circuit breaker (i.e., the incoming line port 2 and / or the outgoing line port 3 on the circuit breaker, the same below) and moves in the direction close to the leakage circuit breaker until it is inserted into the corresponding wiring port, and then stops pushing the slide 813 to continue moving. During this period, the test poles 829 on the two detection components 82 are kept synchronously inserted into the corresponding wiring ports. At the same time, the cooperation between the sample frame 71 and the alignment component 72 is used to align and limit the lifted leakage circuit breaker to be tested. After the plug-in action of the test poles 829 and the corresponding wiring ports on the leakage circuit breaker is completed, the operating handle 4 on the leakage circuit breaker to be tested is toggled through the toggle component 83 to put the circuit breaker in the open state, and then the conductive piece is connected to the two connecting terminal posts of the connecting wire 828 and the test pole 829 to start the test.

[0032] Furthermore, if Figure 9As shown, the conductive part includes a conductive ring column 8210 fixedly passing through the bottom end of the insertion strip 827 and a slot 8214 opened at the end of the two corresponding docking end columns. A circular plate 8211 is fixedly provided at the middle of the inner side of the conductive ring column 8210. Plugs 8213 are movably inserted at both ends of the conductive ring column 8210. A spring 2 8212 is fixedly connected between the two plugs 8213 and the corresponding sides of the circular plate 8211. Among them, the slot 8214 and the plug 8213 are both configured as a frustum-shaped structure. In the process of elastic deformation of the spring 2 8212, the two plugs 8213 always remain inserted into the conductive ring column 8210, and the plug 8213 always remains in the state of being inserted into the inner part of the conductive ring column 8210. It moves in a state of fitting against the inner wall of the conductive ring column 8210. In addition, after the plug 8213 is fully inserted into the corresponding slot 8214, the two springs 8212 are in a compressed state. When the plug 8213 is not inserted into the corresponding slot 8214, the inclined area on the outside of the plug 8213 corresponds to the end of the corresponding docking terminal, ensuring that when the insertion strip 827 moves upward, the plug 8213 will retract into the conductive ring column 8210 when the corresponding docking terminal squeezes its inclined area, until the plug 8213 is directly opposite the slot 8214, completing the conduction of the two docking terminal columns of the connecting wire 828 and the test pole 829.

[0033] It should be noted that in the process of controlling the connection between the conductive part and the two docking terminal posts of the connecting wire 828 and the test pole 829, the cylinder 2 822 is used to drive the lifting plate 821 upward, thereby driving the horizontal plate 1 825 upward synchronously, and then driving the insertion strip 827 to move upward, so that the plug 8213 on the conductive part moves toward the direction of the corresponding docking terminal post until the plug 8213 is fully inserted into the corresponding slot 8214, and the leakage protection test is started. Compared with the traditional integrated test memory, this design can effectively avoid the situation where the test starts before the toggle component has toggled the operating handle 4 into place.

[0034] Furthermore, if Figure 6 As shown, the toggle assembly 83 includes a mounting base and a guide rod 833 fixed on the top of the corresponding slide 813. Cylinder three 831 is fixedly installed on one side of the mounting base. The telescopic end of cylinder three 831 is fixedly connected to a toggle bar 832. The bottom end of the toggle bar 832 is set to an arc surface structure, which can prevent the toggle operating handle 4 from being scratched during the rotation of the toggle operating handle 4. The arc surface end of the toggle bar 832 is facing the operating handle 4 on the leakage circuit breaker, and the other end of the guide rod 833 is movable through the toggle bar 832.

[0035] It should be noted that before controlling the conductive part to conduct electricity with the two docking terminals of the connecting wire 828 and the test pole 829, it is necessary to first use the toggle assembly 83 to toggle the operating handle 4 to deflect it, that is, directly push the toggle bar 832 along the direction of the guide rod 833 through the cylinder three 831 to approach the leakage circuit breaker to be tested, and use the moving toggle bar 832 to push the operating handle 4 to deflect, so that the leakage circuit breaker is in the open state, waiting for the conductive part to connect the two docking terminals of the connecting wire 828 and the test pole 829 to start the test process.

[0036] Furthermore, if Figure 6 and Figure 10 As shown, the alignment component 72 includes a push plate fixedly connected to one side of the horizontal plate 825 and a through slot opened on one side of the sample frame 71, and an inserting plate 721 is movably inserted into the through slot. A straight bar 723 is fixedly provided at one end of the inserting plate 721 close to the push plate, and a straight rod 722 that movably passes through the straight bar 723 is fixed on one side of the sample frame 71. A spring 724 that fixedly connects the sample frame 71 and the straight bar 723 is sleeved on the outside of the straight rod 722. When the spring 724 is in a natural state, the plugging end of the inserting plate 721 remains plugged into the through slot, and the straight rod 722 always remains movably passing through the straight bar 723 during the elastic deformation of the spring 724.

[0037] It should be noted that, in the process of aligning and limiting the multiple leakage circuit breakers to be tested that are pushed into the sample frame 71, after one end of the operating handle 4 installed on the leakage circuit breaker passes through the sample frame 71, the horizontal plate 825 that moves synchronously with the slide 813 is used to push the push plate toward the sample frame 71, and after contacting the straight bar 723, the straight bar 723 is continued to be pushed to move the plug plate 721 toward the leakage circuit breaker, and the plug plate 721 that passes through the slot is used to support one end of the operating handle 4 installed on the leakage circuit breaker, thereby completing the alignment and limiting operation of the leakage circuit breaker to be tested before the start of the test. Among them, after the plug plate 721 that passes through the slot supports the corresponding side surface of the leakage circuit breaker, the test pole 829 is also just plugged into the corresponding wiring port.

[0038] Example 3: Refer to the attached instructions Figure 5 and Figure 11This embodiment is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a lifting mechanism 9 is provided in the lifting area inside the chassis 11, and the lifting mechanism 9 includes a photoelectric sensor 913 installed at the bottom of one of the testing mechanisms 8 for counting the leakage circuit breakers passing through, and a lifting member for lifting the leakage circuit breaker to be tested to the test station for testing, wherein the photoelectric sensor 913 is installed at the bottom of the pad frame 811 near the feeding end of the conveyor belt 14, near one end of the partition bar 12, and is directly opposite to the area where the operating handle 4 on the leakage circuit breaker transported on the conveyor belt 14 is located, so as to facilitate accurate counting.

[0039] Furthermore, if Figure 11-12 As shown, the lifting member includes an L-shaped bracket 91 fixed to the inner side of the chassis 11 and an electric push rod 92 facing the test mechanism 8. The telescopic end of the electric push rod 92 is fixedly connected to a square ring frame 93 movably overlapped on the upper surface of the L-shaped bracket 91. An L-shaped rack 95 is movably inserted inside the square ring frame 93, and a gear 94 is rotatably installed inside the square ring frame 93 to engage with the L-shaped rack 95. A support plate 96 is fixed on the top of the L-shaped rack 95. The gear 94 is driven to rotate by a motor installed on the outside of the square ring frame 93. The above-mentioned related components of the lifting member constitute a lifting unit, which is provided with four units and are respectively arranged at the positions corresponding to the two ends of the two pad frames 811. The two lifting units located on the same side of the conveyor belt 14 share a power source. The top ends of the opposite sides of the support plates 96 on the two lifting units arranged opposite to each other are flared to better support the leakage circuit breaker to be tested to enter the test station. The lifting member also includes a vertical plate 97 fixed to the top of the L-shaped rack 95 and an air bin 910 fixed to the inner side of the partition frame 10. The bottom of the air bin 910 is connected to an air pipe 911, and the other end of the air pipe 911 is connected to an external air source. A plurality of sockets are provided on the vertical plate 97. A shielding arc plate 912 is fixed at the position corresponding to each socket on the side of the vertical plate 97 away from the air bin 910. The other end of the shielding arc plate 912 is fitted with the outer side of the corresponding end of the leakage circuit breaker to be tested, and the vertical plate 97 is fitted with the air outlet end of the air bin 910. In order to ensure that the gas inside the air bin 910 can smoothly pass through the socket on the vertical plate 97 into the wiring port on the circuit breaker to clean the dust remaining therein Dust and other debris can be removed, and the socket on the vertical plate 97 can be aligned with the wiring port on the leakage circuit breaker in the initial state, and a transition air pipe is provided at one end of the air chamber 910 close to the vertical plate 97. The transition air pipe adopts a two-stage structure design that is mutually sleeved, and a reset spring is fixedly connected between the outer sides of the tube bodies at both ends. After the leakage circuit breaker to be tested is supported by two supporting plates 96 that are relatively arranged, the end of the transition air pipe at the end of the air chamber 910 is moved in contact with the outer wall of the vertical plate 97. At this time, the reset spring is in a natural state. In addition, the diameter of the transition air pipe can be set to be larger than the diameter of the socket, so that the air outlet time of the socket can be extended during the upward movement of the vertical plate 97. An electric push rod 2 98 is also fixedly installed on the inside of the chassis 11. The telescopic end of the electric push rod 2 98 is fixedly connected to an isolation frame 99. The isolation frame 99 is composed of a straight plate fixedly connected to the telescopic end of the electric push rod 2 98 and three partition plates fixed on one side of the straight plate. The distance between the two partition plates near the feeding end of the conveyor belt 14 is equal to the sum of the thicknesses of multiple leakage circuit breakers tested in a single batch. The other partition plate is located on the side of the lifting unit away from the feeding end of the conveyor belt 14 away from the other group of lifting units. In addition, the end of each partition plate is set to a V-shaped structure to facilitate the separation of the leakage circuit breakers in transportation.

[0040] It should be noted that, in the process of pushing the leakage circuit breaker to be tested on the conveyor belt 14 to the test station, when the photoelectric sensor 913 detects that the number of the leakage circuit breaker to be tested has passed the lifting unit near the feeding end of the conveyor belt 14 and reaches the batch test quantity, the signal is transmitted to the control end, and the control end controls the electric push rod 2 98 to push the isolation frame 99 or even the area on the conveyor belt 14, and uses the partition plate farthest from the feeding end of the conveyor belt 14 to stop the multiple leakage circuit breakers that have completed the counting. At the same time, the two external The two partition plates are used to separate the leakage circuit breakers entering the area where the lifting units are located near the feeding end of the conveyor belt 14, so that the leakage circuit breakers to be tested outside the lifting area can be blocked for transportation. At this time, two sets of lifting units arranged opposite to each other are used to lift the leakage circuit breakers to be tested in the corresponding areas on the conveyor belt 14 to the test station for testing. Since the leakage circuit breakers to be tested are placed closely on the conveyor belt 14, it can be ensured that the number of leakage circuit breakers entering the two test stations remains consistent after each partition. During the batch test, two electric push rods 92 are arranged opposite to each other to push the corresponding square ring frame 93 toward the conveyor belt 14, so that the two supporting plates 96 moving toward each other support the lower end of the leakage circuit breaker (see Figure 1 ), at this time, the return spring that was compressed in the initial state returns to its natural state, and the end of the transition air pipe fits into the outer wall of the vertical plate 97, and then the motor drives the gear 94 inside the square ring frame 93 to rotate, and the rotating gear 94 is used to drive the L-shaped rack 95 to move upward, thereby lifting the leakage circuit breaker to be tested. The maximum limit of this lifting process is that the wiring port on the leakage circuit breaker is directly opposite to the test pole 829 on the detection component 82, and during the period when the vertical plate 97 rises with it, when the socket on it passes through the area where the transition air pipe is located, the gas inside the air chamber 910 will be squeezed out and enter the corresponding wiring port through the socket, and the dust and other debris remaining in the wiring port will be blown out by the impact force of the airflow. Because of the restriction of the shielding arc plate 912, the dust and other debris discharged from the wiring port can be guided to fall, thereby preventing them from being lifted up and falling into the wiring port again, affecting the test accuracy.

[0041] In the above technical solution, the multiple cylinders mentioned all use single-acting cylinders with model DSA25N200; the multiple electric push rods mentioned all use electric push rods with model HB-DJ801; the photoelectric sensor 913 mentioned uses a mirror reflection type photoelectric sensor with model GL6-P1111.
