Description

Technical Field

[0001] The invention relates to a capacitance measuring and controlling instrument, and in particular to an intelligent capacitance measuring and controlling instrument. Background Art

[0002] Smart capacitors are energy management devices that integrate advanced control technology and automation functions. They are mainly used in power systems to achieve dynamic reactive power compensation and improve the stability and efficiency of the power grid. They can monitor the state of the power grid in real time and automatically adjust reactive power to maintain the system voltage and power factor within the ideal range. Smart capacitors are usually equipped with sensors and control systems, and can work with other devices in the smart grid to perform data analysis and optimization to reduce energy consumption, reduce electricity bills and improve energy efficiency. This device has important applications in power, industrial, commercial and renewable energy systems, and can significantly improve the reliability and sustainability of the overall power system.

[0003] Traditional intelligent capacitance measurement and control instruments mostly adopt an integrated design, that is, the current sensor, voltage sensor, temperature sensor and humidity sensor are integrated into the measurement and control main board. Although this design can save space, it also has several disadvantages. First, since all sensors are integrated on one main board, when a sensor fails, the entire main board needs to be replaced as a whole, which increases maintenance costs and difficulties. Secondly, if the technology or type of a specific sensor needs to be updated, the entire system also needs to be redesigned, which reduces the flexibility of the system.

[0004] In addition, the complexity of the measurement and control mainboard leads to difficulties in installation and debugging. Users often face problems such as small space, messy cables, and interference signals during installation and debugging, which greatly reduces the efficiency and stability of the system. At the same time, the existing standard fixing methods are often not flexible enough, resulting in cumbersome installation and fixing processes of the split structure, which restricts the convenience of users.

[0005] In this regard, it is particularly important to design an intelligent capacitance measurement and control instrument that modularizes the sensor and connects it to the measurement and control main board through a plug-in structure. Through this split circuit board design, the current, voltage, temperature and humidity sensors can be configured on independent split circuit boards respectively, so that each sensor can be replaced and upgraded independently, thereby improving the maintainability and scalability of the system. At the same time, through a convenient and fast fixing structure, the connection between the split circuit board and the measurement and control main board can be easily realized, improving the overall installation flexibility and user convenience.

[0006] Taking the above considerations into consideration, an intelligent capacitor measurement and control instrument based on modular and flexible design concepts came into being. It can not only effectively integrate and monitor multiple parameters of capacitors, but also solve many problems of traditional measurement and control instruments in integrated design, providing a more efficient and flexible solution for capacitor monitoring and management.

[0018] The present invention has the following beneficial effects: 1. In the present invention, a separate individual is formed by setting a split circuit board separated from the measurement and control main board. The split circuit board is used to configure a current sensor, a voltage sensor, a temperature sensor and a humidity sensor. The split circuit board can be inserted into the split assembly hole. When one of the current sensor, the voltage sensor, the temperature sensor and the humidity sensor is damaged, it is only necessary to remove the split circuit board for welding and replacement. Even if the welding disk is damaged, it will not affect the measurement and control main board, thus avoiding the measurement and control main board from being scrapped. The setting of the electrical connection mother seat and the electrical connection sub-seat can form an electrical connection between the split circuit board and the measurement and control main board based on plug-in. The preliminary positioning structure can locate the position of the split circuit board inserted into the split assembly hole. The locking structure can accurately lock the split circuit board.

[0019] 2. In the present invention, the inward-pushing conductive structure will push the locking structure inward, so that each electrical connection pin can be inserted into the electrical connection sub-seat to realize automatic assembly. Compared with the manual inward-pushing method, there will be no problem of the electrical connection pin and the electrical connection sub-seat being unstable due to the pushing distance being too short, and the electrical connection pin being bent and damaged due to the pushing distance being too long. The inward-pushing conductive structure can realize the inward push of a fixed distance, which is safer and more reliable; further, it has the advantage of saving labor.

[0020] On the contrary, when the split circuit board needs to be removed, the inward-pushing conductive structure can quickly separate the electrical connection pins and the electrical connection sub-socket by returning to its original position, and can push the split circuit board out of the split assembly hole; compared with the manual pull-out method, it can reduce the risk of damage caused by human error, avoid the situation where fingers cannot be inserted into the split assembly hole, reduce the exposure of workers during the disassembly process, and automatic disassembly reduces dependence on manual labor, which can reduce labor costs and provide technicians with more time to handle complex or high-value tasks.

[0021] 3. In the present invention, the two horizontal positioning shafts can extend into the two horizontal positioning grooves respectively to prevent the position of the split circuit board from shifting, thereby playing a stabilizing and guiding role.

[0022] 4. In the present invention, the push-in balls in the two preliminary positioning structures can move toward the split assembly holes respectively under the function of the first compression spring, and can be pushed into the two positioning surfaces respectively to achieve the purpose of preliminary positioning of the split circuit board; the anti-slip block can collide with the push-in ball to provide anti-slip protection.

[0023] 5. In the present invention, the locking block in the locking structure can be controlled to move downward to extend into the locking concave surface to achieve the purpose of locking the split circuit board.

[0024] 6. In the present invention, the setting of the cover can not only provide for the assembly of the tension spring, but also collide with the long connecting shaft to play a limiting role. The vertical length of the short connecting shaft is shorter than that of the long connecting shaft, which can ensure that there is always an empty space between it and the cover. After introducing air into the empty space, the air can fill the empty space and then control the locking block to move downward.

[0025] 7. The setting of the sealing shaft in the present invention can ensure the sealing of the empty area, and the perforation can extend the vertical length of the sealing shaft, so that the sealing shaft can always be located in the perforation to maintain the sealing of the empty area.

[0026] 8. The setting of the movable chamber in the present invention provides space for the executing inner shell to move horizontally; the second compression spring applies kinetic energy to the executing inner shell to move rightward, and the executing inner shell maintains the initial state of colliding with the right wall of the movable chamber.

[0027] 9. In the present invention, the transfer inner hole will be closed by the short-circuit shaft in the initial state. After the locking block extends into the locking concave surface, the transfer inner hole is open and connected to the empty area, so that the gas in the empty area can be introduced into the transfer inner hole; the purpose of this setting can form the continuity of the previous and next steps. Only after the locking block extends into the locking concave surface, the execution inner shell will drive the split circuit diagram to move left, avoiding the situation where the execution inner shell moves left independently. The setting of the interval gas connection area can receive the gas introduced into the transfer inner hole, and then drive the execution inner shell to move left; the setting of the first exhaust hole and the second exhaust hole can avoid the situation where the gas in the interval gas connection area cannot be discharged after the transfer inner hole is closed by the short-circuit shaft.

[0028] 10. In the present invention, the gas can be introduced through the outer hose.

[0029] 11. In the present invention, two sealing switches are provided to switch between sealing gas and exhaust gas. BRIEF DESCRIPTION OF THE DRAWINGS

The gas in the empty area 64 will then be introduced into the interval air receiving area 76 through the transfer inner hole 771, the first inner channel 772, the first inner hose 774 and the second inner channel 773. As the air is continuously introduced into the interval air receiving area 76, the execution inner shell 50 will be driven to move leftward, and then the split circuit board 20 locked by the locking block 51 will be driven to move leftward together, until the execution inner shell 50 collides with the left wall of the moving chamber 70. At this time, each electrical connection pin 251 is inserted into the electrical connection sub-seat 26 to form an electrical connection between the split circuit board 20 and the measurement and control main board 12.

[0051] 7. Close the first control valve 961 to prevent gas leakage; the split circuit board 20 and the measurement and control main board 12 maintain a stable electrical connection state.

[0052] When removing the split circuit board 20: 1. First, open the second control valve 962, and the second compression spring 75 applies kinetic energy to the inner housing 50 to move rightward, so that the inner housing 50 collides with the right wall of the movable chamber 70, and each electrical connection pin 251 is separated from the electrical connection sub-base 26, and the split circuit board 20 partially exposes the split assembly hole 13. At the same time, the gas in the spacer gas connection area 76 is discharged through the first discharge hole 81, the second inner hose, the second discharge hole 82 and the auxiliary hose 97 in sequence.

[0053] 2. Then, the first control valve 961 is opened, and the locking block 51 is kept moving upward due to the tension of the tension spring 55. The locking block 51 leaves the locking concave surface 52 and is hidden in the execution inner hole. At the same time, the gas in the empty area 64 is discharged through the first inner hole 91, the third inner hose 93, the second inner hole 92 and the outer hose 94 in sequence.

[0054] In summary; When installing the split circuit board 20 , it is only necessary to insert the split circuit board 20 into the split assembly hole 13 , align the air supply pipe of the handheld small air pump with the first control valve 961 and introduce gas, and finally close the first control valve 961 .

[0055] When disassembling the split circuit board 20, it is only necessary to open the second control valve 962 first, and then open the first control valve.

[0056] The actual operation is convenient.
