Description

Technical Field

[0001] The invention relates to the technical field of leakage protection, in particular to a low-voltage capacitor cabinet with a leakage protection mechanism. Background Art

[0002] The capacitor cabinet can effectively improve the power factor of the power load, reduce line loss, and increase the actual load capacity of the transformer. The use of reactors in the system can effectively prevent harmonic amplification and absorb most of the harmonic current, so that the total probability limit of the harmonic voltage and the limit of each harmonic current content meet the standard, and achieve the purpose of harmonic control. It is used in the substations, production workshops and low-voltage networks of civil buildings of industrial and mining enterprises, and is suitable for power transmission and distribution systems with frequent load changes and unstable reactive power. A leakage protection device is provided in the capacitor cabinet in the traditional technology. Once a leakage is found, the leakage protector disconnects the circuit and the capacitor cabinet stops working. However, the stopping of the capacitor cabinet will inevitably affect the operation of the entire power grid. If the capacitor cabinet with leakage stops working, it will be immediately replaced by the replacement capacitor cabinet. In this way, the capacitor cabinet with leakage stops working to avoid further deterioration of the leakage problem. The capacitor cabinet that takes over can ensure the normal operation of the power grid.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the technical solutions in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 13 The present invention provides a technical solution: a low-voltage capacitor cabinet with a leakage protection mechanism, comprising a first capacitor cabinet 1, a second capacitor cabinet 2 for emergency replacement is arranged on one side of the first capacitor cabinet 1, a power connection group 3 is arranged between the backs of the first capacitor cabinet 1 and the second capacitor cabinet 2, an adjustment mechanism 4 is connected to one side of the power connection group 3, a leakage protection device 5 is fixed on the back of the first capacitor cabinet 1, the leakage protection device 5 detects the leakage inside the first capacitor cabinet 1, and the handle on the leakage protection device 5 after the leakage is detected controls the adjustment mechanism 4 through swing transmission, and the adjustment mechanism 4 includes a disk 6, a pendulum 7, a drive assembly 8 and a plurality of components used to cooperate with the leakage protection device 5. The control unit 9 is transmission-connected to the disk member 6, and the disk member 6 is transmission-connected to the drive assembly 8 with a pendulum 7. The power connection group 3 includes a main pin connector 10 connected to the wires on the first capacitor cabinet 1, a secondary pin connector 11 connected to the wires on the second capacitor cabinet 2, and a third pin connector 12 for selectively connecting power between the main pin connector 10 and the secondary pin connector 11, and the third pin connector 12 is connected to the external circuit wires. The drive assembly 8 is transmission-connected to the third pin connector 12. The first capacitor cabinet 1, the second capacitor cabinet 2, the leakage protection device 5, the main pin connector 10, the secondary pin connector 11 and the third pin connector 12 mentioned in the present invention are prior art devices.

[0033] The overall working process of the present invention is that if leakage occurs in the first capacitor cabinet 1 during operation, after the leakage protection device 5 detects the leakage problem of the first capacitor cabinet 1, the leakage protection device 5 will trip and disconnect the circuit of the first capacitor cabinet 1, so as to avoid the leakage problem on the first capacitor cabinet 1 from being amplified and aggravated. In addition, if the leakage is caused by a person being electrocuted, after the leakage protection device 5 controls the first capacitor cabinet 1 to be powered off, the person will not be further electrocuted, so that he survives and quickly stays away from the capacitor cabinet. The tripping of the leakage protection device 5 will control the power connection group 3 to change the circuit through the adjustment mechanism 4, that is, Figure 3 The pendulum body 7 in the apparatus swings downward, and then the third pin connector 12 slides down and separates from the main pin connector 10, and then the third pin connector 12 is connected to the auxiliary pin connector 11, and the third pin connector 12 is externally connected to the circuit in the power grid, so that the power grid reconnects with the second capacitor cabinet 2, and the second capacitor cabinet 2 replaces the first capacitor cabinet 1 and puts into operation. In addition, the adjustment mechanism 4 has a timing mechanism. After the timing ends, the pendulum body 7 swings in the opposite direction, so that the third pin connector 12 is reconnected with the main pin connector 10, and the external power grid recovers the state of being connected to the first capacitor cabinet 1 at the beginning, because the leakage problem of the first capacitor cabinet 1 may be triggered by a misunderstanding. In the power grid system, the coverage area of ​​the power grid is large, and the capacitor cabinets in remote geographical locations are under the surveillance of the camera. If it is only triggered by a misunderstanding, there is no need for staff to be on-site for processing. When the timing mechanism in the adjustment mechanism 4 ends, the first capacitor cabinet 1 is automatically reconnected to the external power grid circuit. Of course, the adjustment mechanism 4 also needs to be reset after operation to cope with the next leakage shock. Here, the staff can reset the adjustment mechanism 4 during regular treatment and maintenance.

[0040] The disk assembly 31 includes a main disk gear 39, a mainspring 40, an outer shaft 41, an outer gear 42 and an outer worm 43.

The main disk gear 39 and the outer shaft 41 are buffer-connected with the main disk gear 39 and the outer shaft 41. The outer worm 43 and the outer gear 42 are meshingly connected.

[0041] The outer worm 43 and the outer shaft 41 are respectively sleeved in two through holes opened on the concave folding frame 29, and one side of the main plate gear 39 is fixedly connected to the outer end of the mainspring 40 by setting an arc plate, and the inner end of the mainspring 40 is fixedly connected to the outer shaft 41.

[0042] The power head 26 includes a T-shaped frame 44, a transfer shaft 45, a head block 46, a limit arc plate 47 and a second arc-shaped rack 48. The head block 46 is fixed on the folding column frame 25. The transfer shaft 45 is movably sleeved in a through hole opened on the head block 46. The transfer shaft 45 is meshed and connected with a row of teeth arranged on the T-shaped frame 44 through a fixed gear. One end of the transfer shaft 45 is fixedly connected to the pendulum body 7. The T-shaped frame 44 slides through the square hole opened on the head block 46. The control panel 30 It includes a disk rack and an L-shaped column fixed outside the disk rack. The L-shaped column of the control disk 30 supports one end of the T-shaped frame 44, and the limiting arc plate 47 is intercepted on one side of the L-shaped column of the control disk 30. The head block 46 is supported and positioned by setting an L-shaped convex plate to support the limiting arc plate 47. The limiting arc plate 47 is provided with an inner convex block with an arc plate hole, and the second arc rack 48 slides through the arc plate hole. One end of the first control shaft 16 is meshed and connected with the second arc rack 48 through a fixed gear.

[0043] When the first capacitor cabinet 1 has a leakage problem, the leakage protection device 5 will trip and cut off the power. Figure 6 The handle on the leakage protection device 5 is swung upward to push the first V-plate 21, and the first V-plate 21 drives the first follower shaft 20 to rotate during the sliding, and then drives the concave clamping column 28 through the second control shaft 19. Fig.10 The concave folding column 28 in the middle is translated to the right, and the bottom end of the concave folding column 28 is pulled out from the short shaft 38, so that the short shaft 38 can rotate. When the adjustment mechanism 4 is initially put into use, the staff completes the power storage of the disk assembly 31, specifically, using a tool to rotate the outer worm 43, and the outer worm 43 drives the outer gear 42 to rotate. The rotation of the outer gear 42 causes the spring 40 to contract and store power. After the power storage is completed, the adjustment mechanism 4 can be put into work. Therefore, once the short shaft 38 can rotate, the accumulated power will be gradually released, specifically, when the spring 40 expands and deforms to release power, it drives the main disk gear 39 to rotate slowly. Fig.11The spring 40 has a small number of turns for intuitive display. In actual use, the product used slowly releases power to the outside, so that the main plate gear 39 slowly rotates to drive the pinion gear 37, and then the worm 35 is driven through the short shaft 38 to rotate the plate gear 32, and the plate gear 32 drives the central shaft 33 to control the control plate 30 to rotate slowly. Fig.12 , the control disk 30 slowly rotates counterclockwise, and the control disk 30 no longer supports the T-shaped frame 44 at the beginning of the rotation, so that the T-shaped frame 44 can fall, combined with Figure 3 , Figure 4 , Fig.11 and Fig.12 It is understood that the elastic curved sheet 15 provides a downward push force for the directional rack 13, but it cannot push it because the downward swing of the pendulum body 7 will drive the transfer shaft 45 to rotate, thereby causing the T-shaped frame 44 to descend. Therefore, by supporting the T-shaped frame 44, the directional rack 13 can be controlled to be unable to descend, so it returns to the Fig.12 , the control panel 30 rotates clockwise initially, the L-shaped column on the control panel 30 no longer supports the T-shaped frame 44, and the T-shaped frame 44 will fall, and at the same time Figure 4 The directional rack 13 in the middle falls down, and the directional rack 13 drives the third pin connector 12. After the third pin connector 12 is separated from the main pin connector 10, the third pin connector 12 is electrically connected to the auxiliary pin connector 11. Therefore, from the overall function point of view, when the leakage protection device 5 trips, the first capacitor cabinet 1 stops the power supply work inside, and at the same time, the external power grid circuit is electrically connected to the second capacitor cabinet 2, and the second capacitor cabinet 2 replaces the first capacitor cabinet 1 to work.

[0044] Continue back Fig.12 The control disk 30 in the middle, the control disk 30 continues to rotate, and finally the control disk 30 rotates counterclockwise and is blocked by the limit arc plate 47, and the control disk 30 pushes the top support T-frame 44 again, and the T-frame 44 rises to drive the transfer shaft 45 to rotate, thereby controlling the pendulum body 7 to rise and swing, and after transmission control, the directional rack 13 rises to drive the third pin connector 12, and the third pin connector 12 is disconnected from the auxiliary pin connector 11, and is electrically connected to the main pin connector 10 again, so the power grid flushing establishes a connection with the first capacitor cabinet 1. This process is the timing mechanism in the regulating mechanism 4 mentioned. After the timing ends, the first capacitor cabinet 1 resumes normal operation. This situation is mainly for the situation of misunderstanding leakage triggering. In addition, if the staff is accidentally electrocuted, after the first capacitor cabinet 1 is powered off, the staff can run away from the first capacitor cabinet 1 in time.

[0045] Before the first capacitor cabinet 1 is restored to be connected to the grid, the leakage protection device 5 needs to be reclosed, that is, the handle on the leakage protection device 5 needs to be pushed back. Fig.12Before the control plate 30 rotates counterclockwise and contacts the limit arc plate 47, the L-shaped column of the control plate 30 first pushes the second arc rack 48, and the second arc rack 48 slides to the left to drive the first control shaft 16 to rotate, and then Figure 7 The first control shaft 16 rotates to drive the second follower shaft 24, and the second follower shaft 24 rotates to drive the second V-plate 23 to slide downward, and the second V-plate 23 pushes the handle on the leakage protection device 5 to swing and reset. After the reset is completed, the leakage protection device 5 completes the closing work.

[0046] The above process will restore the normal power connection of the first capacitor cabinet 1. If the first capacitor cabinet 1 is leaking due to misunderstanding, it naturally meets the control purpose. However, if the first capacitor cabinet 1 really has a serious leakage, although the leakage protection device 5 is reclosed, the leakage will cause the leakage protection device 5 to trip again. The second tripping requires staff to be on site for maintenance and disposal. Therefore, the present invention is aimed at the situation of misunderstanding leakage. Although this misunderstanding leakage can cause the leakage protection device 5 to trip, it only needs to reclose the leakage protection device 5.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
