Description

Technical Field

[0001] The present invention relates to the technical field of terminal detection, and in particular to an inspection and testing device for a high-performance and low-power consumption electric energy metering completion detection terminal. Background Art

[0002] After the installation, debugging and connection of the electric energy metering device are completed, the electric energy metering completion detection terminal will be used to detect the transformer. It can ensure the accuracy of the measurement, avoid inaccurate measurement caused by transformer errors, and can detect wiring errors and correct them in time to prevent electric energy metering failures and safety hazards caused by wiring problems. It can also ensure the quality of completion acceptance, comprehensively detect the performance of the transformer, and ensure the reliable operation of the electric energy metering device. In addition, it helps to reduce power loss, detect electricity theft, and ensure the safety and stability of the power supply.

[0003] There is a high-performance, low-energy consumption electric energy metering completion detection terminal, which mainly uses the built-in main control chip to generate a 3kHz sinusoidal small signal through PWM modulation, and applies it to one side of the transformer. A signal will be coupled out on the other side. The amplitude of the two signals is calculated by sampling to obtain the transformation ratio. At the same time, the main control chip can also use PWM modulation to generate a small signal whose positive half cycle is twice as long as the negative half cycle. It is applied to one side of the transformer, and the other side will couple out the corresponding signal. The coupled signal is pre-processed and its instantaneous value is collected to determine the length of the positive half cycle and the negative half cycle of the signal, and then determine the polarity of the transformer connection. It has high detection efficiency and low energy consumption.

[0004] In order to ensure that its performance and quality meet the requirements, thereby ensuring the accuracy and reliability of electric energy metering, such equipment needs to be inspected and tested before being put into use to ensure the reliable operation of the electric energy metering device and reduce the losses and risks caused by equipment failure. The commonly used detection method is to use a transformer with a standard ratio and polarity to calibrate the terminal. The ratio and polarity of the standard transformer are tested multiple times by the terminal to verify the accuracy of the transformer detection. However, this method cannot meet the quality assurance requirements of the terminal in complex scenarios: during the completion stage, construction activities are still in progress, such as the installation and commissioning of electrical equipment, and the connection of lines. These activities may cause local temperature increases and may also It affects the surrounding humidity, and the use of surrounding electrical equipment will also interfere with the terminal. Therefore, the detection of the terminal needs to ensure that it can still be used normally under environmental disturbances; secondly, when the terminal detects the polarity of the transformer connection, the instantaneous value is collected after the coupling signal is pre-processed. If the surrounding environment changes rapidly at the moment of collecting the value, it may cause a brief fluctuation in the performance of the electronic components. The instantaneous electromagnetic interference may be coupled into the detection circuit, affecting the accuracy of the signal and thus interfering with the judgment of the polarity. Therefore, the terminal must also meet the anti-interference performance under sudden changes in the environment. Based on the above viewpoints, technical personnel in this field have proposed a high-performance and low-power inspection and detection equipment for the completion detection terminal of electric energy metering. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a high-performance, low-power consumption inspection and testing device for electric energy metering completion detection terminals.

[0018] The present invention has the following technical points and beneficial effects:

[0019] It can simulate whether the terminal to be tested can maintain the accuracy of detection when humidity and temperature change continuously or suddenly. The copper tube is heated to increase the temperature inside the outer casing, thereby simulating whether the detection of the ratio and polarity of the terminal to be tested is accurate under the environment of temperature change. The heated copper tube will heat the water in the water storage humidification component, causing the water in the water storage humidification component to evaporate and generate hot steam. The reel motor pulls the two extrusion plates to move backward. The shielding shell moving backward will squeeze the water storage bag to deform, thereby squeezing out the hot steam generated inside the water storage bag and the water storage tank, and discharge it through the exhaust port on the front sealing frame, so that the humidity outside the terminal to be tested gradually increases, simulating the change of the surrounding humidity, and detecting the terminal to be tested. Whether the detection effect can be maintained normal under humidity changes, when simulating sudden changes in humidity and temperature, the drive frame moves downward and the cross bar between the lever sheets drives the wedge-shaped transmission block to rise. When the wedge-shaped transmission block rises, the heating component will be squeezed by the wedge-shaped transmission block and extended into the water tank. When the water tank is heated, its temperature will not be quickly transferred to the air, but the water stored in the water storage and humidification component will be quickly heated. A large amount of hot steam will gather in the water storage and humidification component in a short time. As the shielding shell moves, the hot steam will quickly spray out from the nozzle. The hot steam causes a sudden change in temperature and humidity in the outer casing, simulating the rapid changes in temperature and humidity under the completed environment. At the same time, it is verified whether the detection terminal to be tested can maintain stability in this harsh environment.

[0020] It can simulate whether the detection terminal to be tested can maintain the accuracy of detection when electromagnetic interference changes continuously or suddenly. The reel motor works to drive the reel on its active end to rotate, tighten the connecting rope, pull the bottom hanging rod through the connecting rope, and then pull the two extrusion plates to move backward. When the extrusion plate moves backward, several shielding shells are opened in layers. As the shielding shell outside the electromagnetic interferer becomes thinner, the electromagnetic disturbance it generates on the detection terminal to be tested gradually becomes stronger, thereby simulating the influence of the electromagnetic disturbance in the environment on the detection terminal to be tested. When simulating the rapid change of electromagnetic disturbance, the driving cylinder drives the driving frame to move downward, and the bottom of the driving frame presses the outer wall of the extrusion plate, and the front end of the extrusion plug rod is inserted into the notch of several shielding shells, so that the several shielding shells are connected to each other. The several shielding shells are pulled by the connecting rope. At this time, the several shielding shells leave the electromagnetic interferer at the same time, and the electromagnetic disturbance inside the outer shell surges, thereby detecting whether the detection terminal to be tested can maintain the accuracy of detection when the surrounding electromagnetic environment changes rapidly.

[0021] It can simulate whether the terminal to be tested can maintain the accuracy of detection when vibrating at different frequencies. When hot steam is discharged from the front sealing frame, the steam is first sprayed on the suspension bracket, driving the spring above the suspension bracket to vibrate, thereby driving the terminal to be tested to vibrate, thereby simulating the vibration of the environment, and detecting whether the detection effect is normal when the terminal to be tested vibrates. The outer wall of the extrusion plate is pressed at the bottom of the driving frame to deform the water storage bag. The deformed water storage bag drives the nozzle to be pressed tightly against the suspension bracket. At this time, as the shielding shell moves, the shielding shell squeezes the water storage tank to deform, and the internal pressure of the water storage tank increases. However, since the nozzle is squeezed under the suspension bracket, the hot steam will not be discharged immediately. However, as the nozzle moves to the bottom of the discharge curved plate, the hot steam will be quickly ejected from the nozzle. The rapidly ejected airflow drives the terminal placement component to vibrate violently, thereby simulating whether the terminal to be tested can maintain the stability of detection when it vibrates greatly.

[0044] like Figure 3 , Figure 4 , Figure 5 and Figure 6 The outer housing 5 is internally and fixedly connected with a mounting frame 8 between the front and rear side walls. The mounting frame 8 includes a tail frame 81, a cylinder mounting frame 82, a driving cylinder 83 and a front sealing frame 84. The front sealing frame 84 is fixed to the front side wall of the tail frame 81, the cylinder mounting frame 82 is fixed to the middle position of the upper side wall of the tail frame 81, and the driving cylinder 83 is installed in the middle position of the upper side wall of the cylinder mounting frame 82.

[0046] like Figure 6 and Figure 8 As shown, the bottom middle positions of the two extrusion plates 1105 are fixedly connected with bottom hanging rods 1102, and the other ends of the two bottom hanging rods 1102 are connected with spring rods 1103 through springs. The traction assembly 12 includes a reel frame 1201, and a reel motor 1202 is installed at the middle position of the upper side wall of the reel frame 1201. The movable end of the reel motor 1202 penetrates the upper side wall of the reel frame 1201 and is arranged inside the reel frame 1201. The reel connected to the movable end of the reel motor 1202 is fixedly connected with a connecting rope 1203, and the other end of the connecting rope 1203 is sleeved in the middle position of the bottom hanging rod 1102. When the reel motor 1202 works, it drives the reel on its movable end to rotate, tightens the connecting rope 1203, and pulls the bottom hanging rod 1102 through the connecting rope 1203, thereby pulling the two extrusion plates 1105 to move backward.

[0047] like Fig.11 As shown, the heating assembly 16 includes two sealing plates 161, and a plurality of heating copper tubes 163 are installed between the two sealing plates 161. The rear side wall of the sealing plate 161 is fixedly connected with a clamping plate 162, and the clamping plate 162 is limitedly slidably connected to the middle position of the front side wall of the wedge-shaped transmission block 131. The two sealing plates 161 are tightly fitted with the groove of the rear side wall of the water storage tank 171.

[0048] Embodiment 2, as Figure 4 , Fig. 9 and Fig.10As shown, this embodiment provides another technical solution based on the first embodiment. The wedge-shaped transmission assembly 13 includes a wedge-shaped transmission block 131, a spring sheet 132 is fixedly connected to the bottom of the wedge-shaped transmission block 131, a return spring 133 is fixedly connected between the spring sheet 132 and the tail frame 81, and a lever transmission assembly 15 is fixedly connected to the bottom of the outer wall of the driving frame 19. The lever transmission assembly 15 includes two transmission rods 151 and two lever sheets 152. The two lever sheets 152 are pin-connected to the tail frame 81 at the front side, and the front ends of the two lever sheets 152 are respectively limited and slidably connected to the bottom of the two transmission rods 151, and the other ends of the two lever sheets 152 are fixedly connected to a cross bar, and the cross bar connected to the other ends of the two lever sheets 152 is arranged below the wedge-shaped transmission block 131 and fits the bottom of the wedge-shaped transmission block 131. The driving frame 19 is fixedly connected to the movable end of the driving cylinder 83, and the bottom of the two side walls of the driving frame 19 is provided at the front side. The wedge-shaped surfaces on both sides of the driving frame 19 match the wedge-shaped surfaces on the outer side walls of the two extrusion plates 1105. The driving cylinder 83 drives the driving frame 19 to move downward. When the driving frame 19 moves downward, the bottom of the driving frame 19 presses the outer side walls of the extrusion plates 1105, causing the water storage bag 172 to deform. The deformed water storage bag 172 drives the nozzle 173 to press tightly against the suspension bracket 92. At the same time, as the two extrusion plates 1105 approach each other, the plug rod 172 is squeezed. The front end of 104 is inserted into the groove of several shielding shells 1101, so that the several shielding shells 1101 are connected to each other. When the driving frame 19 moves downward, the transmission rod 151 drives the front end of the lever piece 152 to be pressed down, and the rear end of the lever piece 152 is lifted, and then the cross bar between the lever pieces 152 is used to drive the wedge-shaped transmission block 131 to rise. When the wedge-shaped transmission block 131 rises, the heating component 16 will be squeezed by the wedge-shaped transmission block 131 and extend into the water tank 171.

[0049] Working principle: before testing the test terminal 18, open the sealing door 7, then place the test terminal 18 on the placement bottom plate 91, then connect the test terminal 18 to the two wiring copper sockets 3, then start the test terminal 18 and close the sealing door 7, and inject water into the water storage humidification component 17 through the water inlet valve 14. During the test, the heating copper tubes 163 are heated, so that the temperature inside the outer casing 5 gradually increases, thereby simulating the test terminal 18 under the environment of temperature change. The polarity detection is accurate, and the heating copper tube 163 heats the water in the water storage humidification component 17, causing the water in the water storage humidification component 17 to evaporate and generate hot steam. At the same time, the reel motor 1202 works to drive the reel on its movable end to rotate, tightening the connecting rope 1203. The connecting rope 1203 pulls the two extrusion plates 1105 to move backward through the bottom hanging rod 1102 and the spring rod 1103. When the extrusion plates 1105 move backward, several shielding shells 1101 are opened in layers, and as the electromagnetic interference device The shielding shell 1101 on the outside of 10 becomes thinner, and the electromagnetic disturbance generated by it on the detection terminal 18 to be tested becomes stronger gradually, thereby simulating the influence of the electromagnetic disturbance in the environment on the detection terminal 18 to be tested, and then detecting whether the detection of the detection terminal 18 to be tested can still maintain accuracy in the environment where the electromagnetic disturbance gradually increases. When the shielding shell 1101 is opened, the shielding shell 1101 moving toward the rear side will squeeze the water storage bag 172 to deform, and then squeeze out the hot steam generated inside the water storage bag 172 and the water storage tank 171, and discharge it through the exhaust port on the front sealing frame 84, so that the humidity outside the detection terminal 18 to be tested gradually increases, simulating the change of the humidity of the surrounding environment, and detecting whether the detection effect of the detection terminal 18 to be tested can maintain normal under the change of humidity. When the hot steam is discharged from the front sealing frame 84, the steam is first sprayed on the suspension bracket 92, driving the spring above the suspension bracket 92 to vibrate, thereby driving the detection terminal 18 to be tested to vibrate, thereby simulating the vibration of the environment, and detecting whether the detection effect of the detection terminal 18 to be tested is normal when it vibrates;

[0050] When exploring the rapid changes in the environment, the driving cylinder 83 drives the driving frame 19 to move downward. When the driving frame 19 moves downward, the bottom of the driving frame 19 presses the outer wall of the extrusion plate 1105, so that the water storage bag 172 is deformed. The deformed water storage bag 172 drives the nozzle 173 to be pressed tightly on the suspension bracket 92. At the same time, as the two extrusion plates 1105 approach each other, the front end of the extrusion plug rod 1104 is inserted into the grooves of the plurality of shielding shells 1101, so that the plurality of shielding shells 1101 are connected to each other. When the driving frame 19 moves downward, the transmission rod 151 drives the front end of the lever sheet 152 to be pressed downward, and the rear end of the lever sheet 152 is lifted, and then the cross bar between the lever sheets 152 is used to drive the wedge-shaped transmission block 131 to rise. When the wedge-shaped transmission block 131 rises, the heating component 16 will be squeezed by the wedge-shaped transmission block 131 and extend into the water storage tank 171.

[0051] Then, the reel motor 1202 drives the reel to rotate, and uses the connecting rope 1203 to pull several shielding shells 1101. At this time, several shielding shells 1101 leave the electromagnetic interferer 10 at the same time, and the electromagnetic disturbance inside the outer shell 5 surges, so as to detect whether the detection terminal 18 to be tested can maintain the accuracy of the detection when the surrounding electromagnetic environment changes rapidly. Since the heating component 16 extends into the water storage tank 171, when the water storage tank 171 is heated, its temperature will not be quickly transferred to the air, but the water stored in the water storage humidification component 17 is quickly heated, and a large amount of hot steam is gathered in the water storage humidification component 17 in a short time. As the shielding shell 1101 moves, the shielding shell 1101 squeezes the water storage bag 17. 2 deformation, the water bag 172 and the water tank 171 are connected, so that the internal pressure of the water tank 171 increases, but because the nozzle 173 is squeezed under the suspension bracket 92, the hot steam will not be discharged immediately, but as the nozzle 173 moves to the bottom of the discharge curved plate 93, the hot steam will be quickly ejected from the nozzle 173, and the temperature and humidity in the outer casing 5 will change suddenly through the hot steam, simulating the rapid changes in temperature and humidity in the completed environment, and at the same time, it is tested whether the detection terminal 18 to be tested can maintain stability in this harsh environment. At the same time, the rapidly ejected airflow drives the terminal placement component 9 to vibrate violently, thereby simulating whether the detection terminal 18 to be tested can maintain the stability of the detection when it vibrates greatly.
