Technical Field

[0001] The present invention relates to the technical field of withstand voltage detection, and in particular to a withstand voltage detection device. Background Art

[0002] "Vacuum circuit breaker" is named because its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and arc extinguishing without maintenance, and is widely used in distribution networks. Vacuum circuit breaker is an indoor power distribution device in 3~10kV, 50Hz three-phase AC system. It can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. It is particularly suitable for use in places that require oil-free, less maintenance and frequent operation. The circuit breaker can be configured in the central cabinet, double-layer cabinet and fixed cabinet to control and protect high-voltage electrical equipment.

[0003] Under the existing technology, the inspection of this type of circuit breaker is usually carried out by workers bundling high-voltage wires on the outgoing end of the circuit breaker and connecting the ground wire at the lower outgoing end for testing. It is easy for the binding to be loose and the workers to repeatedly enter and exit, which may cause safety hazards. Summary of the invention

[0004] In order to solve the problem that the detection of this type of circuit breaker in the prior art is usually performed by workers bundling high-voltage lines on the outlet end of the circuit breaker and connecting the ground wire at the lower outlet end for testing, which is prone to loose bundling and safety hazards caused by workers repeatedly entering and exiting, the present application provides a withstand voltage detection device.

[0007] A detection mechanism is also provided next to the detection frame, and the detection mechanism includes a detection frame, and the detection frame is provided on both sides of the detection platform, and insulators are provided on the detection frames on both sides, and the insulators are rotatably connected to the detection frame and can be electrically connected to the circuit breaker, and the insulator on one side is used to connect to high voltage, and the insulator on the other side is used to connect to low voltage;

[0008] A grounding mechanism is also provided beside the detection frame, and the grounding mechanism is used to connect with the circuit breaker and ground the circuit breaker.

[0009] By adopting the above technical solutions, the function of comprehensive withstand voltage testing of circuit breakers is realized. The test table cooperates with the feeding mechanism to realize automatic feeding, improve work efficiency, and ensure that the testing needs at different angles are met; the control mechanism can not only power the flip mechanism, but also accurately detect and switch the opening and closing status of the circuit breaker to ensure the accuracy of the test conditions. The testing mechanism uses the insulators on both sides to connect to high and low voltages respectively to complete the multi-point and multi-level withstand voltage performance testing of the circuit breaker. The grounding mechanism effectively guarantees the accuracy and safety of the entire testing process and prevents the harm caused by accidental leakage. Since the connection is achieved by rotating the insulator during the test, no mechanical energy operation is required by the staff, which further improves safety.

[0010] Optionally, the detection frame is also provided with a mounting frame, the mounting frame is slidably connected to the detection frame, a plurality of waist-shaped grooves are opened on the mounting frame, the mounting frame can slide toward or away from the detection platform, a plurality of adjustment columns are also provided on the mounting frame, an adjustment frame is slidably provided on the adjustment column, the adjustment frame slides along the adjustment column and can lock the position, the insulators are all rotatably connected to the adjustment frame, and an adjustment cylinder is also provided on the adjustment frame, the end of the adjustment cylinder is hinged to the adjustment frame, and the piston rod of the adjustment cylinder is hinged to the insulator.

[0011] By adopting the above technical solution, the sliding connection design between the mounting frame and the detection frame makes the overall position of the insulator adjustable, which can meet the detection requirements of circuit breakers of different sizes. The waist-shaped groove design facilitates the adjustment and fixing of the position of the mounting frame, improving the operational flexibility. The combined structure of the adjustment column and the adjustment frame further realizes the fine adjustment of the insulator in the vertical direction, ensuring accurate positioning during detection. The addition of the adjustment cylinder 623 enables the angle of the insulator to be dynamically adjusted, and the posture of the insulator can be changed as needed during the detection process, thereby improving the detection efficiency and accuracy.

[0012] Optionally, the flipping mechanism includes a motor and a reducer, the rotating shaft of the motor is drivingly connected to the input shaft of the reducer, and the output shaft of the reducer is drivingly connected to the circuit breaker. The flipping mechanism also includes a sensor, and the sensor is used to detect the rotation angle of the reducer.

[0013] By adopting the above technical solution, the flipping mechanism is composed of a motor and a reducer, the rotating shaft of the motor is connected to the input shaft of the reducer, the output shaft of the reducer is connected to the circuit breaker, and the sensor can make the flipping more precise, thereby realizing a stable and reliable flipping operation of the circuit breaker.

[0014] Optionally, the control mechanism includes a console, on which two control frames are provided. The control frames are both slidably connected to the console and controlled by air cylinders. Control connectors are provided on both of the two control frames. Corresponding to the two control connectors on the detection base, there are mating sockets. One of the mating sockets is electrically connected to the motor and, after being electrically connected to the control connector, powers on the motor. The other mating socket is electrically connected to the circuit breaker and, after being electrically connected to the control connector, detects and controls the opening and closing of the circuit breaker.

[0015] By adopting the above technical solutions, the two control frames on the console can be flexibly adjusted respectively through sliding connection and air cylinder drive, ensuring that the control connectors can accurately dock with the mating sockets on the detection base. During operation, one of the mating sockets is responsible for powering on the motor, thereby starting the flipping mechanism to complete the attitude adjustment of the circuit breaker; the other mating socket is used to detect and control the opening and closing state of the circuit breaker, ensuring the safety and accuracy of the withstand voltage detection process, and improving the automation level and operation efficiency of the equipment.

[0016] Optionally, a conducting piece and a conducting rod are provided on the mating socket. The conducting piece is hinged to the mating socket, and a torsion spring is provided at the hinge. The conducting piece has a tendency to rotate away from the conducting rod. When the control connector moves towards the mating socket, it can push the conducting piece towards the conducting rod. After the conducting piece abuts against the conducting rod, the internal circuit of the mating socket is connected.

[0017] By adopting the above technical solutions, the conducting piece is hinged to the mating socket and has a tendency to rotate away from the conducting rod under the action of the torsion spring. This design can keep the internal circuit disconnected when not in contact, effectively avoiding mis-triggering. When the control connector approaches the mating socket, it can accurately push the conducting piece towards the conducting rod, ensuring a stable electrical connection after the two abut, so as to realize the rapid and accurate connection of the circuit. This structure improves the safety and reliability of equipment operation and simplifies the circuit control process at the same time.

[0019] By adopting the above technical solutions, the grounding rod is installed on the detection table by a sliding connection method and is driven by an air cylinder for precise positioning and contact operation, and can adjust the grounding rod more quickly and switch the grounding state more frequently according to the detection requirements.

[0020] Optionally, a grounding plate is also provided on the detection base corresponding to the reducer. A grounding block is provided on the grounding plate. The grounding block is configured according to the shape of the output shaft of the reducer. The output shaft of the reducer can be embedded in the grounding block. A spring is provided between the grounding block and the grounding plate. The spring has a tendency to push the grounding block towards the output shaft of the reducer.

This design effectively improves the reliability and safety of the grounding operation, simplifies the grounding process, and reduces the need for manual intervention.

[0022] Optionally, the feeding mechanism further includes an alignment base. The alignment base is slidably connected to the detection table and driven by a cylinder. An alignment member and a driving member are provided on the alignment base. The driving member is used to drive the alignment member to rotate. The alignment member can abut against the detection base when rotating.

[0023] By adopting the above technical solution, the alignment base can slide on the detection table and be driven by a cylinder to adjust its position according to actual needs. The alignment member can be rotated driven by the driving member and abut against the detection base during rotation to correct the position of the detection base, ensuring the accurate positioning of the detection base during transportation and improving the accuracy and reliability of subsequent detection.

[0024] Optionally, a pushing member is further provided on the alignment base. The pushing member is used to push the alignment member towards the detection base.

[0025] By adopting the above technical solution, when the alignment member cannot abut against the detection base, the position can be adjusted by the pushing member so that the alignment member can achieve normal alignment.

[0026] This application also provides a withstand voltage detection process, including the above withstand voltage detection equipment, and adopts the following method:

[0027] a. Install the circuit breaker in advance and send the detection base to the detection table through the feeding mechanism;

[0028] b. The control mechanism controls the motor to flip the circuit breaker, and at the same time detects the opening and closing of the circuit breaker and sets the circuit breaker to the open state;

[0029] c. After the control mechanism disconnects the connection, the detection mechanism successively performs withstand voltage detection on the incoming line and outgoing line, between three phases, and between three phases and the shell of the circuit breaker;

[0030] d. The control mechanism controls the circuit breaker to the closed state again;

[0031] e. After the control mechanism disconnects, the detection mechanism successively performs withstand voltage tests on the circuit breaker for the incoming and outgoing lines, between the three phases, and between the three phases and the enclosure.

[0032] By adopting the above technical solutions, multiple withstand voltage tests are respectively carried out in the opening and closing states of the circuit breaker, which can effectively verify the stability of the electrical performance of the circuit breaker. At the same time, the use of the automated control mechanism to cooperate with the feeding mechanism, the flipping mechanism, and the detection mechanism to complete the entire process not only improves the detection efficiency but also reduces the errors caused by human intervention, thereby enhancing the accuracy and consistency of the detection results.

[0033] In summary, the present application has at least the following beneficial effects:

[0034] The present application solves the problem that in the prior art, the detection of this type of circuit breaker is usually carried out by staff bundling high-voltage wires at the outgoing end of the circuit breaker and grounding wires at the lower outgoing end for experiments, which is prone to insecure bundling and potential safety hazards due to the staff repeatedly entering and leaving. The present application feeds the detection base at the detection station and respectively conducts various withstand voltage tests through the insulators on the detection fixture, eliminating the need for staff to bundle wires, improving the detection efficiency and safety.

[0054] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings. Embodiment 1

[0055] A withstand voltage testing device, such as Figure 1 and Figure 2 As shown, it includes a test bench 1, a test base 2, and a feeding mechanism 3. The test base 2 is provided with a support frame 21 and a flipping mechanism 4. The support frame 21 is used to install the circuit breaker. The flipping mechanism 4 can be connected to the circuit breaker in a transmission manner and flip the circuit breaker. The feeding mechanism 3 includes a feeding table 31. The feeding table 31 and the test bench 1 are both provided with a plurality of feeding rollers 11. The feeding rollers 11 are used to transport the test base 2 to move. In specific implementation, before conducting the experiment, the circuit breaker needs to be installed on the support frame 21, the circuit breaker is connected to the support frame 21 by rotation, and then the test base 2 is placed on the feeding table 31. The motor drives each feeding roller 11 to rotate and transport the test base 2 toward the test bench 1, thereby completing the feeding of the circuit breaker. The test bench 1 is composed of a combination of insulating material and non-insulating material, so it should be kept away from the test bench 1 during the experiment.

[0056] like Figure 1 and Figure 2As shown, the feeding mechanism 3 further includes an offset adjustment base 32. The offset adjustment base 32 is slidably connected to the detection table 1 and driven by a cylinder. An offset adjustment member 321 and a driving member 322 are provided on the offset adjustment base 32. The driving member 322 is used to drive the offset adjustment member 321 to rotate, and the offset adjustment member 321 can abut against the detection base 2 when rotating. A pushing member 33 is also provided on the offset adjustment base 32. The pushing member 33 is used to push the offset adjustment member 321 to move towards the detection base 2. In specific implementation, the offset adjustment base 32 moves along the length direction of the detection table 1 and is driven by a cylinder. The driving member 322 uses two cylinders. The two cylinders push the driving member 322 from two directions so that the offset adjustment member 321 can rotate along a square trajectory. During adjustment, the detection base 2 can be accurately aligned by the extrusion of the offset adjustment member 321. The pushing member 33 also uses a cylinder. The offset adjustment member 321 is integrally installed on the pushing member 33, so it can be entirely pushed out by the pushing member 33.

[0057] As Figure 3 and Figure 4 shown, the flipping mechanism 4 includes a motor 41 and a speed reducer 42. The rotating shaft of the motor 41 is in transmission connection with the input shaft of the speed reducer 42, and the output shaft of the speed reducer 42 is in transmission connection with the circuit breaker. The flipping mechanism 4 further includes a sensor 43. The sensor 43 is used to detect the rotation angle of the speed reducer 42. In specific implementation, both the motor 41 and the speed reducer 42 are installed on the support frame 21. The output shaft of the speed reducer 42 can be in transmission connection with the circuit breaker to drive the mechanical energy of the circuit breaker to flip. The sensor 43 uses a proximity switch, and a convex block is provided on the output shaft of the speed reducer 42. When the convex block approaches the sensor 43, the circuit breaker can just flip 180 degrees for subsequent detection.

[0058] As Figure 3 and Figure 5 shown, a control mechanism 5 is also provided beside the detection table 1. The control mechanism 5 can be electrically connected to the flipping mechanism 4 and the circuit breaker. The control mechanism 5 is used to supply power to the flipping mechanism 4, and the control mechanism 5 can also detect and switch the opening and closing of the circuit breaker. The control mechanism 5 includes a control console 51. Two control frames 52 are provided on the control console 51. The control frames 52 are both slidably connected to the control console 51 and controlled by a cylinder. Control connectors 521 are provided on both control frames 52. Corresponding to the two control connectors 521 on the detection base 2, there are mating connectors 22. One mating connector 22 is electrically connected to the motor 41 and is powered on after being electrically connected to the control connector 521. The other mating connector 22 is electrically connected to the circuit breaker and detects and controls the opening and closing of the circuit breaker after being electrically connected to the control connector 521. In specific implementation, both control connectors 521 are connected to the power supply and can supply power to the corresponding mating connectors 22. When connected, the motor 41 can be controlled to flip the circuit breaker, and at the same time, the opening and closing of the circuit breaker can be detected and switched.

[0059] AsFigure 6 As shown, a conduction piece 221 and a conduction rod 222 are provided on the mating socket 22. The conduction piece 221 is hinged to the mating socket 22, and a torsion spring is provided at the hinge. The conduction piece 221 has a tendency to rotate away from the conduction rod 222. When the control joint 521 moves towards the mating socket 22, it can push the conduction piece 221 towards the conduction rod 222. After the conduction piece 221 abuts against the conduction rod 222, the internal circuit of the mating socket 22 is connected. In specific implementation, this design can keep the internal circuit disconnected when not in contact, effectively avoiding mis-triggering, so that the power supply can be conducted and work only when it is fully connected.

[0060] As Figure 1 and Figure 7 As shown, a detection mechanism 6 is also provided beside the detection frame 61. The detection mechanism 6 includes a detection frame 61. The detection frame 61 is arranged on both sides of the detection table 1. Insulators 611 are arranged on both sides of the detection frame 61. The insulators 611 are rotatably connected to the detection frame 61 and can be electrically connected to the circuit breaker. One side of the insulator 611 is used to access high voltage, and the other side of the insulator 611 is used to access low voltage. In specific implementation, the detection mechanism 6 needs to perform various withstand voltage detections for incoming and outgoing lines, between three phases, and between three-phase enclosures as required. When high and low voltages need to be accessed, they are accessed through the insulators 611 on both sides. When accessing, align the insulator 611 with the copper sheet joint on the circuit breaker to complete the power connection.

[0061] As Figure 1 and Figure 7 As shown, a mounting frame 62 is also provided on the detection frame 61. The mounting frame 62 is slidably connected to the detection frame 61. A plurality of waist-shaped slots are formed in the mounting frame 62. The mounting frame 62 can slide towards or away from the detection table 1. A plurality of adjusting columns 621 are also provided on the mounting frame 62. An adjusting frame 622 is slidably arranged on the adjusting column 621. The adjusting frame 622 slides along the adjusting column 621 and can lock its position. The insulators 611 are rotatably connected to the adjusting frame 622. An adjusting cylinder 623 is also provided on the adjusting frame 622. The end of the adjusting cylinder 623 is hinged to the adjusting frame 622, and the piston rod of the adjusting cylinder 623 is hinged to the insulator 611. In specific implementation, the mounting frame 62 can adjust its position in the horizontal direction and can be fixed by bolts in the waist-shaped slots after adjustment. The adjusting frame 622 can adjust its position in the vertical direction and can be fixed by bolts to fix the adjusting plate after adjustment. After adjustment, the insulator 611 can be more accurately aligned for power connection.

[0062] As Figure 8 and Figure 9As shown in the figure, a grounding mechanism 7 is also provided beside the detection frame 61. The grounding mechanism 7 is used to connect to the circuit breaker and ground the circuit breaker. The grounding mechanism 7 includes a grounding rod 71. The grounding rod 71 is slidably connected to the detection table 1 and driven by a cylinder. A connection block 72 is provided on the detection base 2 corresponding to the grounding rod 71. One side of the connection block 72 is electrically connected to the output shaft of the speed reducer 42, and the other side of the connection block 72 can abut against the grounding rod 71. A grounding plate 73 is also provided on the detection base 2 corresponding to the speed reducer 42. A grounding block 74 is provided on the grounding plate 73. The grounding block 74 is arranged corresponding to the shape of the output shaft of the speed reducer 42. The output shaft of the speed reducer 42 can be embedded in the grounding block 74. A spring is provided between the grounding block 74 and the grounding plate 73. The spring has a tendency to push the grounding block 74 towards the output shaft of the speed reducer 42. The grounding block 74 is electrically connected to the connection block 72. During specific implementation, the grounding rod 71 is connected to the ground using a grounding material or a grounding wire, and can be adjusted in a timely manner according to the working conditions required for detection. The connection block 72 and the grounding block 74 need to be connected by a copper wire, and the spring can keep the grounding stable and reduce the situation of potential safety hazards caused by unstable grounding.

[0063] This embodiment also provides a withstand voltage detection process, including the above-mentioned withstand voltage detection equipment, and the following method is adopted:

[0064] a. Install the circuit breaker in advance and send the detection base 2 into the detection table 1 through the feeding mechanism 3;

[0065] b. The control mechanism 5 controls the motor 41 to flip the circuit breaker, and at the same time detects the opening and closing of the circuit breaker and places the circuit breaker in the open state;

[0066] c. After the control mechanism 5 disconnects the connection, the detection mechanism 6 successively performs withstand voltage detection on the incoming and outgoing lines, between the three phases, and between the three phases and the outer shell of the circuit breaker;

[0067] d. The control mechanism 5 controls the circuit breaker to the closed state again;

[0068] e. After the control mechanism 5 disconnects the connection, the detection mechanism 6 successively performs withstand voltage detection on the incoming and outgoing lines, between the three phases, and between the three phases and the outer shell of the circuit breaker.

[0069] Working principle: Embodiment 2

[0070] The main difference between the second embodiment and the first embodiment is that the bottom of the detection platform 1 of the second embodiment is further provided with a grounding protection cover 8, which completely wraps the bottom of the detection platform 1. The grounding protection cover 8 is integrally arranged with the connecting piece in the first embodiment. When grounding is required, the overall grounding can be achieved by contacting the grounding rod 71. A plurality of positioning rods 81 are arranged in the grounding protection cover 8, and the positioning rods 81 are all rotatably connected to the grounding protection cover 8, and the positioning rods 81 are all transmission connected to the feed roller 11. In specific implementation, the positioning rods 81 are made of conductive material. There is no need for copper wire connection between the connecting piece and the reducer 42 in the first embodiment, which reduces the inconvenience of wire distribution. The feed roller 11 and the positioning rods 81 are transmission connected by gear meshing. When the feed roller 11 feeds, the top of the positioning rod 81 can pass through the detection platform 1 and abut the bottom of the detection base 2 after rotation, and the bottom can abut the grounding protection cover 8, and at the same time can abut with the detection base 2 to achieve a positioning effect, and it is reset when discharging, reducing interference with subsequent detection and feeding.

[0071] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
