[0001] The utility model relates to the field of intelligent capacitors, in particular to an integrated intelligent capacitor fine compensation device. Background Art

[0002] In the power system, the improvement of power quality is closely related to the optimization of reactive power compensation technology. As one of the important applications of modern reactive power compensation technology, the integrated intelligent capacitor fine compensation device automatically adjusts the switching of capacitor banks to achieve rapid and accurate compensation of reactive power in the power grid, thereby improving power quality, reducing line losses, and ensuring the stable operation of power equipment.

[0003] As an important component of the compensation device, the performance and stability of the reactor directly affect the overall efficiency of the device. In an environment with high harmonic content, the reactor is easily affected by harmonic currents, leading to problems such as overheating and accelerated insulation aging, which in turn cause failures.

[0004] Existing devices mainly focus on the realization of core compensation functions, but do not give enough consideration to backup plans or emergency mechanisms. When the main equipment fails, there is a lack of timely and effective alternatives, which causes the entire compensation system to be temporarily paralyzed, affecting the reactive compensation effect and power quality of the power grid. Once the inductor or other key components fail, complex processes such as disassembly, replacement and re-debugging are often required, which prolongs the time it takes for the compensation device to resume normal operation.

The power shaft of the power source 505 is connected to the switching seat 502. The power source 505 is used to provide moving power for the switching seat 502. The switching seat 502 moves in the connection box 501 through the drive of the power source 505, thereby realizing rapid power switching. The power source 505 adopts a cylinder and can also adopt a linear motor; the first terminal 507 is installed on the connection box 501, one end of the first terminal 507 is connected to the main inductor 3, and the other end is in contact with the switching seat 502; the second terminal 508 is installed on the connection box 501, one end of the second terminal 508 is connected to the auxiliary inductor 4, and the other end is arranged on one side of the switching seat 502, the auxiliary terminal 401 is connected to the second terminal 508 in the switching mechanism 5, which realizes rapid switching between the main and auxiliary inductors 4, and the first and second terminals 508 are respectively connected to the main inductor 3 and the auxiliary inductor 4, ensuring the continuity and accuracy of power transmission.

The second conductive block 509 is arranged so that when the switching seat 502 moves in the connection box 501, the second conductive block 509 contacts the second terminal 508, and the first conductive block 506 is disconnected from the first terminal 507. The design of the first and second conductive blocks 509 makes the switching process more stable and reliable, reducing contact resistance and energy loss.

The temperature sensor 302 monitors the operating temperature of the main reactor 3 in real time to prevent overheating and protect the equipment from damage. When the temperature is too high, the main reactor 3 has problems such as overload, poor heat dissipation or internal fault. At this time, the circuit can be switched to the secondary reactor 4.

[0035] Reference Figure 3 and Figure 4 The secondary inductor 4 includes: a secondary connection terminal 401 installed on the secondary inductor 4, and the second connection terminal 508 is connected to the secondary inductor 4 through the secondary connection terminal 401.

[0036] Reference Figure 2 and Figure 5 , the power backup module 6 is installed in the integrated housing 1, and the power backup module 6 is connected to the terminal head 504. The power backup module 6 is used to continue to provide power supply when the main power supply is interrupted. When the main power supply is interrupted, it can quickly start and take over the power supply to ensure that the integrated intelligent capacitor fine compensation device will not stop working due to power failure. The power backup module 6 is an uninterruptible power supply; the connecting line 601 is installed on the power backup module 6, and the power backup module 6 is connected to the terminal head 504 through the connecting line 601; the capacitor 2 is installed in the integrated housing 1, and works in conjunction with the main inductor 3 and the auxiliary inductor 4 to further compensate for the reactive power in the power grid by storing and releasing electrical energy, thereby improving the power factor of the power grid. It is installed in the integrated housing 1, which reduces the floor space and wiring complexity, and is convenient for unified management and maintenance; the base 101 is installed in the integrated housing 1, and the capacitor 2, the main inductor 3 and the auxiliary inductor 4 are all installed on the base 101.

[0037] During use, the main power supply is connected to the terminal block 504 through the connecting line 601, and then connected to the conductive plate 503 by the terminal block 504. During the subsequent movement of the switching seat 502, the conductive plate 503 is always in close contact with the terminal block 504. At this time, the first conductive block 506 is in contact with the first terminal 507, and the first terminal 507 is connected to the main terminal 301 of the main inductor 3 to supply power to the main inductor 3. The main inductor 3 starts to work, generating inductive reactive power to compensate for the capacitive reactive power in the power grid, thereby improving the power efficiency. The power factor of the grid, the temperature sensor 302 continuously monitors the operating temperature of the main inductor 3 to ensure that it operates within a safe range. The capacitor 2 works in conjunction with the main inductor 3 to further compensate for the reactive power in the grid by storing and releasing electrical energy. When the main inductor 3 needs to stop working due to maintenance, overload, poor heat dissipation or internal failure, the system detects the state change of the main inductor 3, and the power source 505 of the switching mechanism 5 is turned on to provide moving power for the switching seat 502. The switching seat 502 moves in the connection box 501, driving The first conductive block 506 is disconnected from the first terminal 507, while the second conductive block 509 gradually approaches and contacts the second terminal 508. When the second conductive block 509 is fully in contact with the second terminal 508, the main power is successfully switched to the secondary reactor 4, and the secondary reactor 4 begins to work in place of the main reactor 3. During the switching process, the design of the first and second conductive blocks 509 ensures smooth and reliable switching, reducing contact resistance and energy loss. If the main power is suddenly interrupted, the power backup module 6 will automatically replace the main power and connect to the terminal 504 via the connecting line 601 to continue providing power to the equipment. This ensures that the integrated intelligent capacitor fine compensation device can continue to operate in the event of a power outage, maintaining reactive power compensation for the power grid and ensuring system continuity and reliability. When the main reactor 3 fault is eliminated or maintenance is completed, the control system can switch the main power back to the main reactor 3, allowing the main reactor 3 to resume operation. If the power interruption is resolved, the power backup module 6 will automatically stop working and return to the state of being powered by the main power.

[0038] In summary, compared with the existing technology, it has the following beneficial effects:

[0039] By introducing the secondary reactor 4 as a backup for the main reactor 3, when the main reactor 3 stops working due to a fault or maintenance, the secondary reactor 4 can automatically take over the work, ensuring the continuity and reliability of the system, effectively avoiding the paralysis of the entire compensation system due to a failure of the main equipment, and ensuring the reactive compensation effect and power quality of the power grid.

[0040] The design of the switching mechanism 5 enables the switching process of the main power supply between the main inductor 3 and the secondary inductor 4 to be fast and smooth, thereby realizing rapid switching of the power supply, reducing manual intervention and switching time, helping to shorten the power outage time caused by equipment failure, and improving the system recovery speed.

[0041] By introducing monitoring equipment such as the temperature sensor 302, the operating status of the main inductor 3 is monitored in real time, potential problems such as overheating are prevented, and the equipment is protected from damage. When an abnormality occurs in the main inductor 3, the system can respond quickly and switch the circuit to the secondary inductor 4 to avoid the expansion of the fault and improve the overall reliability and stability of the system.
