TECHNICAL FIELD

[0002] In the power industry and civil electrical systems, low-voltage switchgear and control equipment, especially circuit breakers, as the core components of circuit protection and control, the stability and safety of their performance are directly related to the reliable operation of the power system and the safety of users. With the implementation of GB / T 14048.2-2020 "Low-voltage switchgear and control equipment Part 2: Circuit breakers", the electrical performance, safety performance and experimental methods of circuit breaker products are subject to more stringent requirements. This standard not only covers widely used circuit breaker types such as plastic housing circuit breakers, circuit breakers with residual current protection, and universal circuit breakers, but also specifies experimental specifications for various types of circuit breakers to ensure that products can withstand extreme conditions such as high voltage and large current in actual application, effectively preventing safety accidents such as fires and electric shocks caused by electrical faults.
[0003] However, for plastic housing circuit breakers and circuit breakers with residual current protection, which are non-electric closing and opening function circuit breakers, the electrical life experiment is particularly complex and challenging. When conducting experiments on such products, closing and opening actions need to be achieved through external manual operation. However, due to the harsh experimental conditions, including high voltage and large current environments, it is easy to produce arc short circuit and other dangerous situations, directly threatening the safety of experimenters. In addition, the closing and opening process of these circuit breakers needs to be precisely controlled, not only to ensure the vertical and arc movement trajectory, but also to adapt to the large closing and opening torque requirements of different specifications of products. The experiment requires a large number of times and a long cycle, which puts high requirements on experimental equipment and control systems.

[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0056] like Figure 1-4 As shown, the present invention is a vertical arc combination and separation product experimental detection equipment, including a sample installation support stand 1, a sample installation adjustment plate 2, a three-level quick adjustment mechanism 3, a driving cylinder 4, a quick adjustment track 5 and a control unit 6. The sample installation support stand 1 includes a left experimental stand 11, a right experimental stand 12 and a cylinder control limit output stand 13 arranged between the two experimental stands. The two sides of the cylinder control limit output stand 13 are respectively connected and fixed to the left experimental stand 11 and the right experimental stand 12. The left experimental stand 11 and the right experimental stand 12 are respectively connected and fixed to the left experimental stand 11 and the right experimental stand 12. Each test bench 12 is equipped with a separate sample mounting adjustment plate 2, a driving cylinder 4 and a quick adjustment rail 5, which can be operated simultaneously or according to different test tasks. The control unit 6 is installed on the right side of the right experimental bench 12 to control the operation of the test system. The three-level quick adjustment mechanism 3 is installed on the top of the driving cylinder 4. The three-level quick adjustment mechanism 3 includes an arc drive connector 31, a connecting screw 32 and a sample opening and closing connector 33. The sample opening and closing connector 33 and the arc drive connector 31 are installed on the upper and lower layers of the connecting screw 32.
[0057] By adopting the above technical solution, the experimental bench is used to fix the sample mounting plate and sample mounting, the cylinder control limit output bench 13 is used to separate the experimental bench and the cylinder limit remote control input and output, the driving cylinder 4 is used as the driving unit to promote the operation of the experimental product, the cylinder stroke is adjustable, and the three-level quick adjustment mechanism 3 can make fine adjustments to the experimental product front and back, up and down, and is used to precisely connect the experimental product to the mechanism. The left experimental bench 11 and the right experimental bench 12 can both be independently equipped with a sample mounting adjustment plate 2, a driving cylinder 4 and a quick adjustment track 5. The dual experimental bench design enables the equipment to run two test tasks simultaneously. , or run separately according to different test requirements, which greatly improves the test efficiency and flexibility. The setting of the cylinder control limit output stand 13 ensures the stability and accuracy of the driving cylinder 4 during action. It is fixed between the left and right experimental stands 11 and 12, providing the necessary support and limit functions, which helps to accurately control the movement and positioning of the sample. The three-level rapid adjustment mechanism 3 realizes the rapid and precise adjustment of the sample curvature through the combination of the curvature drive connector 31, the connecting screw 32 and the sample opening and closing connector 33. The design of the three-level rapid adjustment mechanism 3 not only improves the adjustment efficiency, but also ensures the accuracy of the test results.
[0058] The arc drive connecting member 31 is provided with a cylinder connecting hole 311 and a first screw connecting hole 312. The cylinder connecting hole 311 is circular, and the first screw connecting hole 312 is an elongated circular arc. The cylinder connecting hole 311 is connected to the driving cylinder 4, and the first screw connecting hole 312 is connected to the connecting screw 32.
[0059] The sample opening and closing connecting piece 33 is provided with a second screw connecting hole 331, a sample connecting hole 332 and a sample connecting rod 333. The second screw connecting hole 331 is circular, the sample connecting hole 332 is a long arc shape, and the sample connecting rod 333 is installed in the sample connecting hole 332. Limiting heads 334 are provided at both ends of the sample connecting rod 333, and the diameter of the limiting head 334 is larger than the diameter of the sample connecting hole 332.
[0060] By adopting the above technical solution, the cylinder connection hole 311 on the arc drive connector 31 is designed to be circular, facilitating a stable and flexible connection with the drive cylinder 4. The first screw connection hole 312 is an elongated circular arc, allowing the connecting screw 32 to be adjusted in angle within a certain range. This flexibility enables the three-stage rapid adjustment mechanism to adjust the sample's arc as needed to meet different testing requirements.
[0061] The second screw connection hole 331 on the sample opening and closing connector 33 is connected to the connecting screw 32, achieving a stable connection with the arc drive connector 31. At the same time, the long arc design of the sample connection hole 332 and the limit head 334 of the sample connection rod 333 ensure the stability and accuracy of the sample during the connection process. The diameter of the limit head 334 is larger than the diameter of the sample connection hole 332, which effectively prevents the sample connection rod from falling off during the test.
[0062] During the process of pushing the sample, the connecting screw 32 will move in the groove of the first screw connecting hole 312, without exerting external force on the product. When disconnecting the product, under the downward driving force of the mechanism, the product handle is pulled downward by the screw to disconnect the product. It can not only provide external force-free driving for vertical arc products, but also provide comprehensive support for products with unrelated human operation sections.
[0063] The sample mounting adjustment plate 2 includes an upper mounting plate 21 and a lower mounting plate 22. Adjustment slots 23 are provided in the middle of the upper mounting plate 21 and the lower mounting plate 22. The two sides of the upper mounting plate 21 and the lower mounting plate 22 are connected to the left experimental bench 11 and the right experimental bench 12 by bolts. The upper mounting plate 21 and the lower mounting plate 22 can slide up and down on the left experimental bench 11 and the right experimental bench 12 to adjust the height.
[0064] By adopting the above technical solution, the sample mounting adjustment plate 2 consists of an upper mounting plate 21 and a lower mounting plate 22, and an adjustment slot 23 is provided in the middle of both, so that the upper mounting plate and the lower mounting plate can slide in the vertical direction on the left experimental bench 11 and the right experimental bench 12 to adjust the height, so that the equipment can adapt to samples of different heights and sizes, improve the versatility and flexibility of the equipment, and be compatible with the installation of any type of plastic shell, residual and other experimental products. The experimental product can be quickly moved left and right on the sample mounting adjustment plate 2 to enable the product to quickly cooperate with the experimental drive mechanism. At the same time, the sample mounting adjustment plate 2 itself can be freely moved up and down on the mounting stand to enable the product to make a large-scale up and down adjustment corresponding to the drive mechanism.
[0065] The quick adjustment track 5 includes a track frame 51, a positioning movable slider 52 and a heavy-duty support track 53. The heavy-duty support track 53 is installed on the track frame 51, and the positioning movable slider 52 is installed at the bottom of the driving cylinder 4 and is connected and slidably connected to the heavy-duty support track 53 on the track frame 51.
[0066] By adopting the above technical solution, the quick adjustment track 5 realizes the precise positioning of the driving cylinder 4 and the connecting parts through the combination of the heavy-duty support track 53 and the positioning movable slider 52. The quick adjustment track 5 serves as the supporting component of the driving cylinder 4, and is composed of 4 positioning movable sliders 52 and 2 heavy-duty support rails 53. In addition to the supporting function, it can also quickly move back and forth and lock the position, so as to quickly position the experimental product in the axial position. This mechanism and the sample installation adjustment plate 2 cooperate with each other to realize rapid positioning and installation of the sample.
[0067] The driving cylinder 4 includes a cylinder fixing plate 41, an air pressure regulating valve 42 and a pilot solenoid valve 43. The air pressure regulating valve 42 and the pilot solenoid valve 43 are installed on the cylinder control limit output stand 13. The air pressure regulating valve 42 and the pilot solenoid valve 43 are connected to the driving cylinder 4. The cylinder fixing plate 41 is installed at the bottom of the driving cylinder 4. The cylinder fixing plate 41 is connected to the positioning moving slider 52 to carry the driving cylinder 4 to move on the heavy support rail 53. A driving positioning plate is also provided on the top of the driving cylinder, which can prevent the cylinder push rod from rotating and shifting during the operation of the cylinder, and ensure that the product position and origin limit will not be out of control due to displacement.
[0068] By adopting the above technical solution, the design of the cylinder fixing plate 41 effectively prevents the cylinder push rod from rotating and shifting during the operation of the cylinder, ensuring that the cylinder push rod always maintains the correct direction and position during the movement, thereby avoiding the situation where the product position and origin limit are out of control due to displacement, and improving the stability and reliability of the equipment during the test process;
[0069] The air pressure regulating valve 42 allows the operator to precisely adjust the air pressure output of the driving cylinder according to the test requirements. By adjusting the air pressure, the speed and force of the cylinder operation can be controlled to meet the requirements of relevant standards, which helps to ensure the stability and accuracy of the sample during the test process, and also helps to extend the service life of the cylinder;
[0070] The pilot solenoid valve 43 controls the operation of the pneumatic power by the suction and release of the solenoid valve. The control mechanism has the characteristics of fast response speed and high control accuracy. It can realize the rapid start and stop of the cylinder, as well as smooth acceleration and deceleration, thereby improving the testing efficiency and accuracy of the equipment, and also reducing the noise and vibration caused by unstable operation of the cylinder.
[0071] The control unit 6 includes a PLC touch screen all-in-one machine 61 and an electrical control box 62 . The electrical control box 62 is installed on the right side of the right experimental bench 12 , and the PLC touch screen all-in-one machine 61 is installed on the electrical control box 62 .
[0072] A test system for vertical arc combination and separation product experimental detection equipment, comprising:
[0073] Experimental display module A, such as Figure 6 , used to select experimental projects and display the data content and status of partition modules;
[0074] Magnification selection module B, such as Figure 20 , an analog ratio selection function is set for each analog channel to improve the accuracy of analog data acquisition. The default ratio of the channel is 1000 / 10V. In order to improve the accuracy, the experimenter can select different voltage / current transmitters and needs to adjust the transmitter ratio in the ratio selection module B. The parameter adjustment of this interface is extremely risky. The system does not display this interface normally. To enter this interface, you must be an authorized senior experimenter and enter the system's highest administrator-level password to enter. After the system power outage, all ratio selections automatically return to the initial value.
[0075] Experimental Demonstration Module A includes:
[0076] Parameter input module C, such as Figure 7 , set the on-off time and experimental interval time of the experimental product. Each channel is independent and can be selected and configured by the experimental personnel according to actual needs. Each experimental product is protected by multiple analog channels. In the simplest case, one analog channel can also provide protection for two experimental products with the same experimental parameters. Under normal circumstances, two analog channels can provide comprehensive protection for one sample. The selection method is very simple. First, select the voltage / current acquisition method, then set the monitoring threshold, and finally select the input. At this time, the analog sampling of the channel is successfully put into use;
[0077] Data acquisition module D, such as Figure 13 , divided into two parts: 4-channel analog data acquisition and 4-channel digital data acquisition. Digital data acquisition is used to collect the switch signal of the experimental product. Each channel, like the analog channel, can be freely allocated by the experimenter according to the experimental requirements. The digital channel has two input states, normally open and normally closed, which can be selected by the experimenter according to the situation of the product.
[0078] The protection selection module E is used to select the real-time monitoring of samples and the protection of the experimental system during the experiment. The experimental equipment control and protection system has the ability to intelligently identify the real-time status of the product during the experiment. Through the analog and digital data collected in the data acquisition area, the program can analyze in real time whether the tested product is normal. If a product abnormality is found, the corresponding protection strategy will be automatically adopted. For example, if one of the products cannot be closed, because the fault itself does not affect the safety of the system, the system will automatically stop the operation of the product mechanism, while the unfaulted product will continue the experiment. If the switch cannot be disconnected, because this will pose a significant risk to the experimental system, the system will immediately terminate all experiments and quickly cut off the experimental power supply to ensure system safety. The system protection function is the highest protection level of this experimental mechanism and has the highest priority. As long as a system fault that affects system safety is found, the experimental power supply will be immediately cut off to ensure the safety of the experimental system. Sample monitoring and system protection are both intelligently calculated based on the collected data and related time.
[0079] The experiment control module F is used to perform comprehensive control of the experiment, including local start and stop, remote start and stop, experiment confirmation, time base selection, clearing / resetting, fault silence confirmation, etc. Figure 17 ;
[0080] The local start / stop button is used to test whether the system is operating normally on site. This button can only be started when the system is not powered. Once the system detects power, the button will immediately reset to the stop state and cannot be selected;
[0081] The remote start / stop button is used to select whether the experimental equipment is controlled locally or remotely. This experiment is extremely risky, so local start is not allowed during normal experiments. Therefore, this button defaults to remote. Only when the system detects that the experimental circuit has no power will the experimenter be allowed to switch to the local state and the local start / stop can be activated. Once the experimental circuit is found to have power, the system will immediately switch to the remote state and cannot switch back to the local state.
[0082] The time base selection button is used to improve the experimental control accuracy. The experimental mechanism and control system set two time bases of 10ms and 100ms. The system defaults to 100ms as the common experimental base time. When high-precision experiments are required, this button can be used to set the experimental base time to 10ms high-precision control mode, providing an option for high-precision experiments.
[0083] The experiment confirmation button is used to prevent the experimenter from accidentally starting the experimental system. Only after the experimenter presses this button and confirms that the experiment needs to be carried out, can the control system be activated and the next operation be carried out;
[0084] The reset / zero button is used when the experimental control mechanism and control system detect an experimental fault and start the system protection. The experimenter must click this button to clear the fault alarm signal and restore the control system to its initial state after confirming the fault and taking measures. All parameters need to be reset and the operation process must be followed before the experiment can be carried out again.
[0085] The fault mute confirmation button is used to clear the fault alarm found by the control system of the experimental organization that does not affect the safety of the experimental system. This button only clears the fault alarm signal and does not affect the progress of the experiment.
[0086] Status indication module G, such as Figure 18 , mainly indicates the real-time status of the equipment and the occurrence of faults;
[0087] Run the timing module H, such as Figure 19 , used to count down for 10 seconds after the system starts running, giving the experimenter the final confirmation time. After the countdown ends, the system officially enters the experimental process.
[0088] A method for detecting a test system of a vertical arc combination and separation product experimental detection equipment specifically comprises the following steps:
[0089] Step 1: According to the installation position requirements of the sample to be tested, adjust the spacing of the sample installation adjustment plate 2 to ensure that the spacing meets the sample installation spacing standard. After the adjustment is completed, the sample is initially placed on the adjustment plate for initial positioning. The cylinder fixing plate 41 is moved to accurately align it with the initial position of the handle of the sample to be tested. By adjusting the height of the sample installation adjustment plate 2 and the left and right movement of the sample on the adjustment plate, the sample position is further accurately adjusted. When the sample position is determined, the sample installation adjustment plate 2 and the sample are fixed using the locking mechanism to complete the sample positioning and installation;
[0090] Step two: adjust the position of the cylinder, so that the arc drive connection 31 on the upper part of the cylinder and the test sample are properly aligned in the axial position, lock the cylinder fixing plate 41, ensure the stability of the cylinder platform position, use the three-stage fast adjustment mechanism 3 to fine-tune the position of the arc drive connection 31 and the handle of the test sample, ensure that they match, connect the handle of the product to be tested with the sample opening and closing connection 33 through the sample connecting rod 333, and the connection should be controlled within 2-5mm to adapt to different sizes of products to be tested;

In addition to its own safety protection system, this special experimental equipment can be connected to the laboratory's highest level protection system when necessary to achieve more comprehensive protection. After pressing this button, the experimental equipment is connected to the laboratory's highest level protection system, and this experiment is under the protection of the laboratory's total protection system;
[0093] Then turn to the data acquisition module D, such as Figure 14 In the analog data acquisition channel position, after this experiment, the electrical life is 1000 times. Select the first analog sampling channel to collect voltage signals and the second analog sampling channel to collect current signals.

After all the values are entered, click "Start" respectively, and the two channels will be put into data acquisition. Figure 15 In the digital data acquisition channel position, because there are two samples this time, each sample corresponds to two digital input channels. Digital input channels 1 and 2 correspond to the 1# experimental product, and digital input channels 3 and 4 correspond to the 2# experimental sample. The product is a molded case circuit breaker, so the normally open sampling mode is selected. Therefore, the normally open mode is set for each channel. After selecting, select "ON" and all four digital channels are turned on.
[0094] Enter the protection selection module E position, such as Figure 16 , when the sample monitoring protection input is 30 (300ms), and when the system protection input is 60 (600ms), after selecting them respectively, both sample monitoring and system protection are put into operation;
[0095] After confirming that all parameters have been set, ensuring that the operating conditions of the experimental equipment are sufficient and error-free, select the experiment confirmation button in the experiment control module F, and a 10-second countdown will appear in the operation timing module H between the start of the experimental system and the formal experiment, so that the experimenter has a final review process before the formal experiment. Then start the experiment. During the experiment, the status indication module G is used to indicate the real-time status of the system operation to remind the experimenter to pay attention.
