Description

Technical Field

[0001] The present invention relates to the technical field of intelligent power capacitors, and in particular to an anti-harmonic intelligent power capacitor. Background Art

[0002] The anti-harmonic intelligent power capacitor mainly reduces the harmonics in the circuit by selecting and matching the parameters of the reactor and the capacitor, avoids the resonance caused by the harmonics, and ensures that the capacitor can normally play the role of compensation and filtering. In the prior art, such as the chassis-type anti-harmonic capacitor disclosed in the Chinese patent document CN203800594U, and the intelligent power capacitor for resisting harmonic current disclosed in CN221239516U, all adopt a similar anti-harmonic intelligent power capacitor structure design, including a chassis shell, an installation cavity is provided in the chassis shell, and a plurality of combined groups of capacitors and reactances are installed in the installation cavity, and the anti-harmonic is connected and controlled by a circuit breaker and a controller. Intelligent power capacitors have a self-protection function. When abnormal faults such as overcurrent, overvoltage, and overtemperature are detected, the circuit breaker is triggered to open the circuit and the entire machine is returned for protection. Considering that anti-harmonic intelligent power capacitors are generally installed by fastening the base bolts to ensure the stable operation of internal devices, the circuit breaker must be opened first during regular active maintenance, or passive maintenance and repair are required when the power capacitor is returned for protection. At this time, it is obviously too troublesome to disassemble the entire capacitor. Even if there is an inspection port on the side of the capacitor, it is inconvenient to operate only through the inspection port during maintenance and repair in complex situations because each group of capacitors and reactances is not easy to remove separately. Therefore, further improvement and optimization is needed. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide an anti-harmonic intelligent power capacitor to solve the problem of inconvenient maintenance and repair operation of the existing anti-harmonic intelligent power capacitor.

[0004] Based on the above purpose, the present invention provides an anti-harmonic intelligent power capacitor, including a chassis shell, in which a circuit breaker, a capacitor and multiple groups of reactances are installed:

[0005] An inspection port is provided at the front end of the chassis shell, a bottom mounting frame is fixedly connected to the bottom end of the chassis shell, and the bottom ends of the capacitor and the reactance are slidably connected to the bottom mounting frame for sliding toward the front end of the inspection port and being pulled out;

[0006] The front end of the bottom mounting frame is vertically plugged with a front baffle, the bottom end of the front baffle is connected to a limit block, the bottom end of the bottom mounting frame is horizontally plugged with a horizontal connecting plate, a movable slider is slidably connected to the horizontal connecting plate, and the limit block is pushed upward by the movable slider to make the front baffle abut against the front side of the bottom end of the capacitor or the front side of the bottom end of the reactance, the front end of the movable slider is telescopically connected with an insert, the front end of the insert is connected with a handle, the front end of the chassis shell is provided with a through hole for the handle to pass through, and the front end of the chassis shell is located on one side of the through hole and is connected to a horizontal groove;

[0007] When the circuit breaker is closed and then opened, the trigger plug extends forward to allow the handle to pass through the opening and out of the chassis shell. By pulling the handle horizontally, the plug is driven to move horizontally along the horizontal groove until the moving slider slides off the limit block, and the limit block and the front baffle move downward, so that the corresponding capacitor or reactance slides out toward the front end of the inspection port.

[0010] Preferably, the front end of the capacitor and the front end of the reactance are respectively connected to front baffles, and when the front baffles are in contact with the front side of the bottom end of the capacitor or the front side of the bottom end of the reactance, the corresponding front baffles are in a closed inspection port state.

[0011] Preferably, an elastic telescopic part is provided at the bottom end of the bottom mounting frame, and the top of the movable end of the elastic telescopic part is connected to a top block, the front end face of the top block is designed as an inclined end face, a through slot is opened in the plug along its length direction, a rotating piece is rotatably connected to the front end of the through slot, and blocking pieces are connected at both sides of the bottom end of the rotating piece in the through slot, which are used to prevent the rotating piece from rotating to the bottom of the through slot. When the circuit breaker is closed, the movable end of the elastic telescopic part is triggered to pop up upward, and the top block pushes the rotating piece to rotate upward and pass through the top of the through slot. When the circuit breaker is closed and then opened, the movable end of the elastic telescopic part elastically returns downward and pushes the rotating piece through the inclined end face of the top block to make the plug extend forward.

[0012] Preferably, one end of the horizontal connecting plate is fixedly connected to a fixed sliding block, and a blocking block is fixedly connected to a position on one side of each movable sliding block on the horizontal connecting plate. When the circuit breaker is closed and then opened, the inserts of the movable sliding block and the fixed sliding block are triggered to extend forward.

[0015] Preferably, the bottom mounting frame is designed in a door-shaped structure.

[0016] The beneficial effects of the present invention are as follows: the bottom end of the capacitor and the bottom end of the reactance are slidably connected to the bottom mounting frame, the front end of the bottom mounting frame is vertically plugged with a front baffle, the bottom end of the front baffle is connected to a limiting block, the bottom end of the bottom mounting frame is horizontally plugged with a horizontal connecting plate, and a moving slider is slidably connected to the horizontal connecting plate. When the capacitor is operating normally, the moving slider pushes the limiting block upward so that the front baffle is in a state of abutting against the front side of the bottom end of the capacitor or the front side of the bottom end of the reactance. When the circuit breaker is closed and then opened, the trigger plug extends forward so that the handle passes through the outside of the chassis shell along the through opening, and the handle at the bottom end of the corresponding capacitor and reactance is selected. By pulling the corresponding one or more handles horizontally, the plug is driven to move horizontally along the horizontal groove until the moving slider slides off the limiting block, and the limiting block and the front baffle move downward under the action of their own weight, so that the corresponding capacitor or reactance can be slid and pulled out toward the front end of the inspection port, so that the faulty component can be removed from the inside of the chassis shell to the outside in a targeted manner, and efficient and convenient maintenance operations can be performed.

[0038] like Figure 1 , Figure 2 , Figure 3 , Fig.11 As shown, an anti-harmonic intelligent power capacitor includes a chassis shell 100, in which a circuit breaker, a capacitor 200 and a plurality of reactance groups 300 are installed, an inspection port 101 is opened at the front end of the chassis shell 100, a bottom mounting frame 1 is fixedly connected to the bottom end of the chassis shell 100, the bottom ends of the capacitor 200 and the reactance 300 are slidably connected to the bottom mounting frame 1, and are used to slide and withdraw toward the front end of the inspection port 101, a front baffle 2 is vertically inserted at the front end of the bottom mounting frame 1, a limit block 3 is connected to the bottom end of the front baffle 2, a horizontal connecting plate 4 is horizontally inserted at the bottom end of the bottom mounting frame 1, a movable slider 5 is slidably connected to the horizontal connecting plate 4, and the limit block 3 is pushed upward by the movable slider 5 so that the front baffle 2 is in contact with the circuit breaker 101. The front end of the movable slider 5 is telescopically connected to the plug 6, and the front end of the plug 6 is connected to the handle 7. The front end of the chassis shell 100 is provided with a through-hole 102 for the handle 7 to pass through. The front end of the chassis shell 100 is located on one side of the through-hole 102 and is connected to a transverse groove 103. When the circuit breaker is closed and then opened, the trigger plug 6 extends forward to make the handle 7 pass through the chassis shell 100 along the through-hole 102. By pulling the handle 7 laterally, the plug 6 is driven to move laterally along the transverse groove 103 until the movable slider 5 slides off the limit block 3, and the limit block 3 and the front baffle 2 move downward, so that the corresponding capacitor 200 or reactance 300 slides out toward the front end of the inspection port 101.

[0039] The present invention is based on the existing conventional anti-harmonic intelligent power capacitor structure, including a chassis shell 100, in which a circuit breaker, a capacitor 200 and a plurality of groups of reactances 300 are installed, and an inspection port 101 is provided at the front end of the chassis shell 100, wherein slots 104 are provided on both sides of the top of the chassis shell 100, and the slots 104 on one side are used to install the circuit breaker, which is connected to the external incoming line through the terminal interface on the circuit breaker, and the operating handle of the circuit breaker passes through the slot 104, which is convenient for opening and closing the switch ... The slot 104 on the side is used to install the display screen 400, and the display screen 400 is interconnected with the controller inside the chassis shell 100 for intelligent operation and control display. The outer edge of the base of the chassis shell 100 is integrally connected with a mounting plate 105, and a waist-shaped hole is provided on the mounting plate 105 for bolt fastening and installation to ensure stable operation of the internal components. In addition, a plurality of dust-proof and heat-dissipating ports 106 are provided on the chassis shell 100. In particular, a bottom mounting frame 1 is fixedly connected to the bottom end of the chassis shell 100. Preferably, as Figure 2 As shown, the bottom mounting frame 1 is designed as a door-shaped structure, and is fastened to the bottom end of the chassis shell 100 by bolts at the outer edge of the bottom end, so as to achieve the purpose of stable connection and saving weight and space;

[0040] The bottom ends of the capacitor 200 and the reactor 300 are slidably connected to the bottom mounting frame 1, and are used to slide and withdraw toward the front end of the inspection port 101. The front end of the bottom mounting frame 1 is vertically plugged with a front baffle 2, and the bottom end of the front baffle 2 is connected to a limit block 3, and the bottom end face of the limit block 3 is designed to be an inclined end face. The bottom end of the bottom mounting frame 1 is horizontally plugged with a horizontal connecting plate 4, and a movable slider 5 is slidably connected to the horizontal connecting plate 4. When the anti-harmonic intelligent power capacitor is operating normally, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the movable slider 5 pushes the limit block 3 upward to make the front baffle 2 abut against the front side of the bottom end of the capacitor 200 or the front side of the bottom end of the reactance 300, that is, the capacitor 200 and the reactance 300 are prevented from sliding outward, and the front end of the movable slider 5 is telescopically connected with the plug 6, and the front end of the plug 6 is connected with the handle 7. The front end of the chassis shell 100 is provided with a through hole 102 for the handle 7 to pass through, and the front end of the chassis shell 100 is located on one side of the through hole 102 and is connected to a transverse groove 103. When the anti-harmonic intelligent power capacitor is operating normally, the handle 7 is flatly closed on the through hole 102 and is flush with the outer end surface of the through hole 102, so as to hide The shielded design avoids misoperation under normal operation. When the circuit breaker is opened after closing, for example, when regular active maintenance is required, the circuit breaker is disconnected first, or the power capacitor is returned for protection, the circuit breaker is disconnected, and passive maintenance and repair are required. At this time, the trigger plug 6 is extended forward to make the handle 7 pass through the opening 102 outside the chassis shell 100, so that it is easy to hold and pull the handle 7 horizontally. According to the object of regular active maintenance, or according to the alarm fault information during passive maintenance and repair, the handle 7 corresponding to the bottom end of the capacitor 200 and the reactance 300 can be selected. By pulling the corresponding one or more handles 7 horizontally, the plug 6 is driven to move horizontally along the horizontal groove 103, such as Figure 6 , Figure 7 , Figure 8 As shown, until the movable slider 5 slides off the limit block 3, the limit block 3 and the front baffle 2 move downward under the action of their own weight, so that the corresponding capacitor 200 and the reactance 300 lose the blocking limit at their front ends, so that the corresponding capacitor 200 or the reactance 300 can be slid and pulled out toward the front end of the inspection port 101, so as to facilitate the targeted removal of the faulty components from the inside of the chassis shell 100 to the outside, and perform efficient and convenient maintenance operations. When the corresponding capacitor 200 and the reactance 300 are pulled out for maintenance, their bottom ends also block the front baffle 2 from moving upward, so that the movable slider 5 cannot be moved back and reset until the corresponding capacitor 200 and the reactance 300 are repaired and pushed in. Only when it is in place in the chassis shell 100, can the sliding block 5 be pushed back to reset, and the limit block 3 and the front baffle 2 be pushed upward to reset. In the case of passive maintenance and repair, if the operator believes that there is no abnormal problem, he can choose to directly push up the circuit breaker to close the switch, and push in the handle 7 to reset. There is no order of closing the switch and pushing in the handle 7, and both are normal operations. If the operator forgets and does not pull the handle 7, he can choose to directly push up the circuit breaker to close the switch. At this time, the corresponding capacitor 200 and reactance 300 remain stationary, and the handle 7 also remains in the pop-up state to remind subsequent maintenance personnel to check again during maintenance.

[0041] When the limit block 3 moves downward under the action of its own weight, it can directly abut on the horizontal connecting plate 4, or a supporting plate can be provided on the bottom mounting frame 1 to prevent the limit block 3 from falling downward.

[0042] In an embodiment of the present invention, Figure 2 , Figure 6, Fig. 9 , Fig.10 As shown, the bottom end of the capacitor 200 and the bottom end of the reactor 300 are respectively connected to the bottom support plate 8, and are slidably connected to the bottom mounting frame 1 through the bottom support plate 8.

[0043] Among them, the rear end of the bottom mounting frame 1 can be fixedly provided with an L-shaped stop block 20, which is used to abut the left and right corners of the rear end of the bottom support plate 8. Optionally, the front baffle plate 2 can be designed as a short plate, which is only used to abut the middle position of the front end of the bottom support plate 8. The front baffle plate 2 can also be designed as a long plate, and guard plates 21 are connected to the left and right sides of the front baffle plate 2, which are used to abut the left and right corners of the front end of the bottom support plate 8. More preferably, a flexible cushion layer can be provided on the inner side of the L-shaped stop block 20 or the front baffle plate 2, and the bottom edge of the front end of the bottom support plate 8 can be designed with an arc-shaped chamfer, which is convenient for the front baffle plate 2 to move up and abut against the front side of the bottom end of the bottom support plate 8, and the bottom support plate 8 is fixed by fastening and clamping it by the L-shaped stop block 20 and the front baffle plate 2.

[0044] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, the front end of the capacitor 200 and the front end of the reactor 300 are respectively connected to the front baffle 107. When the front baffle 2 is in a state of abutting against the front side of the bottom end of the capacitor 200 or the front side of the bottom end of the reactor 300, the corresponding front baffle 107 is in a state of closing the inspection opening 101 and being flush with the outer end surface of the inspection opening 101. Specifically, the front baffle 107 can be designed as a hollow structure, and a door handle 108 can be installed on the front end surface of the front baffle 107. Hand 108 makes it more convenient to pull out capacitor 200 and inductor 300. Gaps are left between the front baffle 107 and the front end surfaces of capacitor 200 and inductor 300, as well as between the front baffle 107 and the front side of the bottom end of the bottom support plate 8. For example, the top end of the front baffle 107 can be fixedly connected to the top flying edge of the capacitor 200 and inductor 300, so as not to affect the normal operation of the capacitor 200 and inductor 300, nor to affect the front baffle 2 abutting against the bottom front side of the bottom support plate 8.

[0045] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16As shown, an elastic telescopic member 9 is provided at the bottom end of the bottom mounting frame 1. Specifically, conventional components such as an electric telescopic rod can be used. A top block 10 is connected to the top of the movable end of the elastic telescopic member 9. The front end face of the top block 10 is designed as an inclined end face. A through slot 61 is provided in the insert 6 along its length direction. A rotating piece 62 is rotatably connected to the front end of the through slot 61. Stoppers 60 are connected to the positions on both sides of the bottom end of the rotating piece 62 in the through slot 61 to prevent the rotating piece 62 from rotating downward to the bottom of the through slot 61. That is, the rotating piece 62 is limited by the stopper 60 and can only be flipped to the top of the through slot 61, but cannot be rotated to the bottom of the through slot 61. Therefore, when the circuit breaker is closed, as shown in FIG. Fig.13 As shown, the elastic telescopic member 9 is triggered to be powered on to cause its movable end to pop up, as shown in FIG. Fig.14 , Fig.15 As shown, the top block 10 pushes the rotating piece 62 to rotate upward and pass through the through slot 61. When the circuit breaker is closed and then opened, the elastic telescopic member 9 is de-energized and its movable end elastically returns downward. Fig.16 As shown, since the rotating piece 62 cannot be turned downward, the rotating piece 62 is pushed by the inclined end surface of the top block 10 so that the inserting piece 6 extends forward.

[0046] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, one end of the horizontal connecting plate 4 is fixedly connected to a fixed slider 11, and the front end of the fixed slider 11 is also telescopically connected to a plug 6, and the front end of the plug 6 is connected to a handle 7. A blocking block 41 is fixedly connected to a position on one side of each movable slider 5 on the horizontal connecting plate 4. When the circuit breaker is closed and then opened, the movable slider 5 and the plug 6 of the fixed slider 11 are triggered to extend forward. If it is necessary to actively maintain all the capacitor 200 and reactance 300 modules, or according to the alarm fault information during passive maintenance and overhaul, all the capacitor 200 and reactance 300 modules need to be passively maintained, the handle 7 of the fixed slider 11 can be pulled horizontally, as shown in FIG. Fig. 9 As shown, the horizontal connecting plate 4 is driven to move horizontally. At this time, the blocking block 41 pushes each movable slider 5 to move horizontally synchronously, so that all the capacitors 200 and reactances 300 can be moved forward and withdrawn, and the operation is simpler.

[0047] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, a plug-in rod 12 is vertically inserted into one side of the movable slider 5 near the block 41. Specifically, the top of the plug-in rod 12 passing through the movable slider 5 is an arc-shaped end. An elastic component such as a spring can be connected between the plug-in rod 12 and the inside of the movable slider 5 to achieve an elastic connection of the plug-in rod 12. The bottom end of the plug-in rod 12 passes through the outside of the movable slider 5 and is connected to a connecting rod 13. The connecting rod 13 is designed in an L-shaped shape. A limiting hole 40 for the connecting rod 13 to be inserted is provided at the bottom of the block 41, so that when the movable slider 5 pushes the limiting block 3 upward, as shown in FIG. Figure 5 As shown, the limit block 3 presses the head end of the plug rod 12, that is, the arc surface end, so that the connecting rod 13 is in the lower state of being out of the limit hole 40. If only the handle 7 of the movable slide block 5 is pulled to move horizontally, the corresponding movable slide block 5 slides away from the limit block 3 and also slides away from the blocking block 41 synchronously, so that the connecting rod 13 will not be inserted into the limit hole 40. Only when the handle 7 of the fixed slide block 11 is pulled to move horizontally, the horizontal connecting plate 4 moves horizontally and pushes each movable slide block 5 to move horizontally synchronously, each movable slide block 5 slides away from the limit block 3, and the plug rod 12 pops up. Figure 8 As shown, the connecting rod 13 is in the upper state inserted into the limit hole 40. After the maintenance and inspection is completed, it is only necessary to push the handle 7 of the fixed slider 11 or any one of the movable sliders 5 back and reset, and drive the movable sliders 5 to move back and reset synchronously through the blocking block 41, until the limit block 3 and the front baffle 2 are pushed up and reset, and then the handle 7 is pushed into the through opening 102, and the circuit breaker is pushed up to close, so that the capacitor can be controlled to operate normally again.

[0048] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, the rear sides of the bottom ends of the capacitor 200 and the rear sides of the bottom ends of the reactor 300 are respectively connected with the connectors 14. Specifically, the connectors 14 can adopt the existing conventional rod-shaped structure design. The connectors 14 are elastically plugged into the rear sides of the bottom ends of the capacitor 200 and the rear sides of the bottom ends of the reactor 300, and the connectors 14 on the adjacent sides are designed as a solid rod-shaped male head structure on one side and a hollow rod-shaped female head structure on the other side. The bottom ends of the connectors 14 are connected with vertical rods 15. Specifically, the vertical rods 15 can be connected to the bottom ends of the connectors 14 on each adjacent side, or can be connected only to the bottom end of the connector 14 on the head side, as shown in FIG. Figure 4As shown, the bottom end of the vertical rod 15 is slidably connected to the horizontal connecting plate 4. Specifically, a slide rail 16 can be vertically connected to the horizontal connecting plate 4, and the bottom end of the vertical rod 15 is slidably connected to the slide rail 16. Fig. 9 As shown, when the horizontal connecting plate 4 moves horizontally, it drives the vertical rod 15 to move horizontally synchronously, and drives the connector 14 to move horizontally to the right synchronously through the vertical rod 15, driving the male head of the connector 14 on the adjacent side to connect with the female head. At this time, by pulling any one of the door handles 108, all the capacitor 200 and reactance 300 modules can be pulled out, and when the horizontal connecting plate 4 moves back and resets, the connector 14 also elastically returns and resets, and the connector 14 is elastically plugged into the rear side of the bottom end of the capacitor 200 and the rear side of the bottom end of the reactance 300, so that when only the movable slider 5 moves horizontally, it is not easy to drive the horizontal connecting plate 4 to slide.
