Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, and in particular to a three-phase compensation capacitor with a low-cost internal insertion film. Background Art

[0002] At present, with the continuous development of power systems, three-phase compensation capacitors are widely used in many fields, such as reactive power compensation, filtering and energy storage. Traditional three-phase compensation capacitors mainly rely on external controllers and sensors for charge and discharge control and status monitoring, which increases the complexity and cost of the system. At the same time, traditional capacitors lack early warning systems and protection mechanisms and are easily damaged under abnormal conditions. Therefore, the development of a low-cost, high-performance three-phase compensation capacitor is an important demand in the current technical field.

[0005] 2. Traditional three-phase compensation capacitors are usually not equipped with sensor monitoring devices, which means that during the use of the capacitor, if problems such as overvoltage, overcurrent, abnormal temperature, etc. occur, the system cannot monitor and respond in real time. The lack of this function increases the risk of capacitor damage, thereby affecting the stability and safety of the entire system, so there is a problem of low safety. Utility Model Content

[0032] like Figure 2 As shown, a moving groove is provided inside the bracket 6, and the moving rod 9 is slidably connected inside the moving groove.

[0033] like Figure 2 As shown, a rectangular groove is provided inside the rectangular block 7, and the moving block 8 is slidably connected inside the rectangular groove.

[0034] like Figure 3 As shown, a spring 27 is commonly connected to the two rollers 15 .

[0035] like Figure 2 As shown, a rotation groove is provided inside the support rod 14, and a rotating wheel 16 is rotatably installed inside the rotation groove.

[0036] like Figure 4 As shown, a slide groove is provided inside the fixed block 20, and the slide bar 21 is slidably connected inside the slide groove.

[0037] like Figure 1 As shown, two grooves and three placement grooves are respectively provided inside the capacitor 1 , two release films 3 are respectively located inside the two grooves, and three components are respectively fixed inside the three placement grooves.

[0038] In this embodiment, when the device is used, in a three-phase compensation capacitor 1 with a low-cost intercalated film, by welding the connecting wire 4 to the top of the capacitor 1, the stability of the connecting wire 4 can be ensured. This is the first step in normal operation. Next, the positioning device 5 is welded to the top surface of the capacitor 1, and it is ensured that the connecting wire 4 is located in the center of the positioning device 5. This step is to further fix the connecting wire 4 and improve its stability and reliability. When using the positioning device 5, first push the push block 10, the push block 10 drives the moving rod 9, and the moving rod 9 drives the moving block 8 to move. At this time, the moving block 8 is in contact with the inclined surface at the bottom of the limit block 11. When the push is continued, the limit block 11 is pushed upward, the limit block 11 drives the vertical block 12 to move, and the vertical block 12 drives the lower positioning block 13 to move. While the limit block 11 moves, the two rotating wheels 16 move along the inclined surfaces on both sides of the limit block 11. The rotating wheel 16 drives the support rod 14 to move, the support rod 14 drives the guide rod 18 to rotate, and the guide rod 18 drives the side positioning block 19 to move. At this time, the lower positioning block 13 and the side positioning block 19 simultaneously clamp and fix the outer peripheral surface of the connecting wire 4. This design can effectively prevent the connecting wire 4 from loosening or falling off, ensure the safety of the capacitor 1 during use, increase the fixing points between the wire and the capacitor 1, thereby reducing the vibration and movement of the wire during operation, and prevent the connecting wire 4 from loosening or falling off, thereby reducing the safety risks caused by poor contact, making subsequent maintenance work easier, because the connecting wire 4 is fixed in a relatively stable position, which is convenient for inspection and replacement. The stability of the connecting wire 4 is ensured by the combined use of welding and positioning device 5, which provides a strong guarantee for the subsequent stable operation and use;

[0039] In addition, by using a release film 3 to separate and wind three different numbers of turns on a component, the same capacitance value can be achieved, which means that by adjusting the number of turns of the coil, the required capacitance value can be obtained without changing other parameters. This design flexibility enables the capacitor 1 to be quickly and efficiently adjusted according to actual needs, thereby better meeting various different application needs; when the capacitor 1 is in the gold spraying process, zinc powder is sprayed onto the capacitor 1, due to the repulsive effect of the release film 3, the zinc powder will be pushed away by the release film 3 so that it will not adhere to the release film 3. This feature is crucial to preventing the accumulation of zinc powder on the release film 3, because if zinc powder accumulates on the release film 3, it may cause the performance of the capacitor 1 to deteriorate or other problems to occur. The release film 3 plays a key role in the low-cost interpolation film three-phase compensation capacitor 1. It not only ensures that zinc powder will not accumulate on the release film 3 during the gold spraying process, but also achieves the same capacitance value design by adjusting the number of turns of the coil, thereby improving the performance and stability of the capacitor 1.

[0040] Example 2

[0041] like Figure 1 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that an integrated temperature sensor 22 and a charge and discharge controller 23 are respectively installed on the outer peripheral surface of the capacitor 1, and a warning light 24 and a sound 25 are respectively installed on the top of the capacitor 1. The integrated temperature sensor 22, the charge and discharge controller 23, the warning light 24 and the sound 25 are electrically connected. A reminder sticker 26 is adhered to the outer peripheral surface of the capacitor 1. Through the arrangement of the charge and discharge controller 23 and the warning light 24 and other structures, the integrated temperature sensor 22 and the charge and discharge controller 23 can improve the operating efficiency and stability of the capacitor 1. The warning light 24, the sound 25 and the reminder sticker 26 all play a warning role, which improves the operating safety and reliability of the capacitor 1 and reduces the equipment maintenance cost. At the same time, it is also convenient for operators to monitor and manage, and solves the problem of low safety.

[0042] In this embodiment, the temperature of the capacitor 1 can be monitored in real time by integrating the temperature sensor 22. Combined with the charge and discharge controller 23, the charge and discharge process of the capacitor 1 can be effectively controlled to ensure its stable operation. When the temperature is too high or other abnormalities occur, the warning light 24 will light up, and the speaker 25 will sound an alarm to promptly warn the operator. The prompt label can provide basic information and operating instructions about the capacitor 1 to help quickly identify the cause of the problem. Through temperature monitoring and charge and discharge control, overheating and excessive charge and discharge can be prevented, thereby extending the service life of the capacitor 1 and ensuring safety during operation. The operator can easily view the information on the prompt label to understand the specifications and precautions of the capacitor 1. Combined with the alarm system of the warning light 24 and the speaker 25, the problem can be quickly located and solved. Through precise charge and discharge control, the operating efficiency of the capacitor 1 can be optimized and unnecessary energy waste can be reduced. In addition to real-time monitoring and early warning, the prompt label can also provide preventive maintenance suggestions and measures to help operators better maintain and manage the capacitor 1, improve the operating efficiency and safety of the capacitor 1, reduce maintenance costs, and enhance overall reliability, solving the problem of low safety.
