Reactive power compensation cabinet is composed of power electronic converter, control system and filter device. It detects the voltage and current parameters of the power grid in real time through current transformers and voltage transformers, so as to calculate the reactive power demand of the current power grid, and then calculates the required reactive power compensation amount according to the detected reactive power demand, and generates corresponding control signals. The control signals drive the power electronic converter to adjust the output voltage and current phase to provide the required reactive power compensation.

[0019] like Figure 1~Figure 5 As shown, a second slide groove 7 is provided in the center of one side where the capacitor base 3 is slidably connected to the slide groove 2. When the capacitor base 3 is set in the slide groove 2, a limiting mechanism is set in the second slide groove 7. A slide groove 3 8 is provided on the slide groove 2. The limiting mechanism is set in the slide groove 3 8. The slide groove 4 10 cooperates with the slide groove 2. When the limiting seat 9 slides in the slide groove 3 8 to be aligned with the slide groove 2, the capacitor base 3 can slide on the slide groove 2 and the slide groove 4 10. At this time, the slide groove 4 10 is separated from the second slide groove 7. When the limiting seat 9 slides on the second slide groove 7, the slide groove 4 10 slides in the slide groove 3 8. When the slide groove 4 10 is aligned with the slide groove 2, the capacitor base 3 can slide on the slide groove 2 and the slide groove 4 10. At this time, multiple capacitors 4 can be replaced at one time by replacing the capacitor base 3.

[0020] like Figure 3~Figure 5As shown, the limit mechanism includes a limit seat 9, a clamping assembly and a screw rod 11. The limit seat 9 is slidably arranged in a slide groove 3 8. A slide groove 4 10 is provided on the limit seat 9. Two clamping assemblies are provided. The two clamping assemblies are respectively arranged on both sides of the cabinet 1.

The worm wheel 13 needs to be driven to rotate by the worm 14, and the worm wheel 13 cannot drive the worm 14 to rotate. When the two worms 14 rotate, the two worm wheels 13 are driven to rotate, thereby causing the screw 11 to rotate. At the same time, because the worm wheel 13 cannot drive the worm 14 to rotate, the screw 11 can only be rotated when two staff members control the worm 14 to rotate at the same time. When only one staff member controls the worm 14 to rotate by rotating the handle 16, the screw 11 cannot rotate, thereby preventing the staff from operating incorrectly.

The pressing frame 20 is fixedly arranged in the cabinet 1. Two clamping assemblies are provided. The two clamping assemblies are detachably arranged on the cabinet 1 respectively. The clamping assembly is detachably connected to the pressing frame 20. The clamping assembly is used to fit and press the connecting plate 1 18 and the connecting plate 2 19. The contacting portion of the connecting plate 18 and the connecting plate 2 19 is arranged between the pressing frame 20 and the clamping frame 21. The connecting plates 18 and the connecting plates 2 19 in this embodiment can preferably be copper plates. The connecting plates 18 and the connecting plates 2 19 are tightly pressed by the pressing plate and the clamping frame 21 so that they are fully in contact for electrical connection, thereby conducting current.

[0022] like Figure 3~Figure 8 As shown, the clamping assembly includes a clamping frame 21, a pushing component, a clamping strip 1 22 and a clamping strip 23. The clamping frame 21 is detachably connected to the pressing frame 20. Two pushing components are provided. The two pushing components are arranged on both sides of the cabinet 1. The two ends of the clamping frame 21 are detachably connected to the two pushing components respectively. The pushing components are used to push the clamping frame 21 to fit with the pressing frame 20. A plurality of clamping strips 1 22 are provided.

When the clamping frame 21 slides, the clamping strips 1 22 and the clamping strips 2 23 move toward the pressing frame 20. As the clamping strips 1 22 and the clamping strips 2 23 gradually slide onto the pressing frame 20, the clamping frame 21 and the pressing frame 20 clamp the connecting plate 1 18 and the connecting plate 2 19. Similarly, when the clamping frame 21 is separated from the pressing plate, the connecting plate 18 and the connecting plate 2 19 can be separated.

[0023] like Figure 2 and Figure 7 As shown, the pushing component includes a docking port 24, a fifth slide groove 25, a second screw rod 26 and a docking block 27. The docking port 24 is provided on the cabinet 1, and two ends of the clamping frame 21 extend out of two docking ports 24 respectively.

[0024] In summary, the working principle of this reactive power compensation cabinet is as follows: when the capacitor fails, the docking block 27 is separated from the screw rod 26, and the screw rod 26 is rotated to drive the clamping frame 21 to separate from the pressing frame 20. At this time, the connecting plate 18 and the connecting plate 2 19 are no longer tightly fitted, and the sliding and rotating handle 16 is slid in the clamping frame 12 to make the gear 15 mesh with the gear 2 17. Two staff members simultaneously rotate the rotating handle 16 to drive the worm 14 to rotate, and the worm 14 drives the worm wheel 13 to rotate, and the worm wheel 13 drives the screw 11 to rotate, so that the limit seat 9 and the slide groove 4 10 slide. When the slide groove 4 10 is aligned with the slide groove 1 2, the capacitor base 3 can slide on the slide groove 4 10 and the slide groove 1 2, and the capacitor base 3 is slid away from the cabinet 1, and the capacitor base 3 provided with a new capacitor 4 can be sent into the cabinet 1 through the slide groove 1 2 and the slide groove 4 10, and the connecting plate 1 18 and the connecting plate 2 19 are pressed and fitted by the clamping frame 21 to complete the capacitor replacement.
