Description

Technical Field

[0001] The present application relates to the technical field of power connection, and in particular to a connector for distribution network compensation. Background Art

[0002] There are a large number of inductive loads in the distribution network, such as motors, transformers, etc. These loads consume a large amount of reactive power during operation. Parallel capacitors can generate reactive power opposite to the reactive power consumed by the inductive loads, thereby playing a role in reactive power compensation in the power grid. Since the load of the power grid changes all the time, capacitors need to be frequently connected to the power grid in parallel. Therefore, a special connection device is needed to adapt to the ever-changing load of the distribution network.

[0003] The Chinese patent with publication number CN 208782110 U and name “An Insulated Connector for Distribution Network” specifically states that external threads are respectively provided on the outer peripheries of the upper and lower ends of the connector body. After the fixing part is removed, the left half body and the right half body can be moved away from each other by external force to expose the cable connector in the connector, which is convenient for disassembly and installation, and convenient for maintenance when a failure occurs in the connection between the cable in the connector and the corresponding connector, thereby reducing the difficulty of maintenance, reducing maintenance costs, and extending the service life of the connector.

[0004] The above-mentioned existing technology can also realize the function of connecting cables when in use, but on the one hand, the above-mentioned existing technology only quickly connects the ends of the wires, which can only play the role of connecting the cables, and cannot adjust the power grid when the load of the power grid changes; secondly, when the load of the power grid changes, the capacitor cannot be connected in parallel to the power grid according to the use requirements, and the amount of capacitor incorporated cannot be increased or decreased according to the use requirements; based on this, there is still room for improvement on the basis of the existing power transfer equipment.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1-14 A connector for distribution network compensation provided in an embodiment of the present invention includes a connecting shell 1, which is in a circular ring structure, and a circular ring groove is arranged on the connecting shell 1; a compensation component 2, which is installed inside the circular ring groove, and the compensation component 2 includes a plurality of compensation units 21, a power connection unit 22 and a driving unit 23, and the driving unit 23 is configured to drive the compensation unit 21 to move up and down, so as to control the number of parallel connections between the compensation unit 21 and the power connection unit 22; a power connection pole 3, which is installed in the middle of the connecting shell 1, and an input interface 31 and an output interface 32 are arranged on the power connection pole 3, and the input interface 31 is electrically connected to the output interface 32 through the power connection unit 22; a sealing plate 4, which is in a ring structure, and the sealing plate 4 is used to seal the circular ring groove.

[0036] In the above technical solution, the deformation-closed path between the input interface 31, the power connection unit 22 and the output interface 32, during the stable operation of the distribution network, controls the up and down movement of the compensation unit 21 through the driving unit 23, and then controls the number of parallel connections between the compensation unit 21 and the power connection unit 22. The compensation unit 21 can reduce the reactive power provided by the grid power supply to the inductive load and transmitted by the line. Since the flow of reactive power in the grid is reduced, the power loss caused by the transmission of reactive power in the line and transformer can be reduced, which helps to improve the stability and economy of the grid and provide users with more reliable and efficient power supply.

[0037] It should be noted that since the grid load changes all the time, the number of parallel compensation units 21 needs to change frequently, so it is necessary to accurately control the number of compensation units 21 quickly put into operation or cut off in parallel with the power connection unit 22 to adapt to the change of grid load.

[0038] It should also be noted that when the compensation unit 21 is connected in parallel to the power grid, the compensation unit 21 can make up for the lack of reactive power at the end of the power grid and reduce the flow of total reactive power in the system, which helps to improve the power factor of the substation and significantly increase the voltage level. Conversely, when the compensation unit 21 is removed from the power grid, the power factor and voltage value will decrease accordingly.

[0039] See also Figure 8 As shown, as a preferred technical solution of this embodiment, the compensation component 2 also includes a main body 20 for fixing the compensation unit 21. The main body 20 is an annular plate with a C-shaped structure. The inner side surface of the main body 20 is provided with slots evenly arranged along its circumference, and the compensation unit 21 is installed in the slots.

[0040] See also Figure 8-Figure 13 As shown, as a preferred technical solution of this embodiment, the compensation unit 21 includes: a connecting frame 211, which is a rectangular structure, a connecting groove matched with the groove is arranged on the outer side of the connecting frame 211, a rotating groove is arranged on the centripetal side of the connecting frame 211, and a mounting groove is arranged on the centrifugal side of the connecting frame 211; a compensation capacitor 212, the compensation capacitor 212 is installed in the mounting groove; a rotating member 213, the rotating member 213 is installed inside the rotating groove through a bearing; a limit member 214, the limit member 214 is installed on the centripetal side of the connecting frame 211, and the limit member 214 is used to limit the rotation of the rotating member 213; an electrical connection member 215, the number of which is two, the electrical connection members 215 are symmetrically installed at the upper and lower ends of the rotating groove, the two electrical connection members 215 are respectively connected to the positive and negative electrodes of the compensation capacitor 212, and the rotating member 213 is configured to drive the electrical connection member 215 to expand outward and be electrically connected to the electrical connection unit 22.

[0041] In the above technical solution, when the compensation capacitor 212 needs to be connected to the power grid in parallel, the drive unit 23 rotates clockwise. When the drive unit 23 contacts a rotating member 213, the rotating member 213 rotates and drives the power connection member 215 to expand outward and electrically connect to the power connection unit 22. At this time, the limit member 214 can limit the rotating member 213, and the power connection member 215 will not shrink inward, thereby realizing the function of connecting the compensation capacitor 212 to the power grid in parallel. When the compensation capacitor 212 needs to be removed from the inside of the power grid, the drive unit 23 rotates clockwise. 23 rotates counterclockwise, the driving unit 23 will first drive the limiting member 214 to separate from the rotating member 213, and the driving unit 23 will then drive the rotating member 213 to rotate in the opposite direction, so that the power receiving member 215 that expands outward moves inward and separates from the power receiving unit 22, thereby realizing the function of cutting off the compensation capacitor 212 from the inside of the power grid; the number of compensation capacitors 212 connected in parallel to the power grid can be increased or decreased by the forward or reverse rotation of the driving unit 23, and the power connection adjustment effect of the compensation capacitor 212 is good and the adjustment is rapid, which is conducive to coping with changes in the power grid load.

[0042] By controlling the rotation angle of the driving unit 23, the amount of contact between the driving unit 23 and the rotating member 213 can be controlled, and the amount of parallel connection of the compensation capacitor 212 can be controlled. Therefore, the compensation capacitor 212 can be quickly put into or removed by the rotation angle of the driving unit 23.

[0043] It should be noted that when the compensation capacitor 212 is connected in parallel to the power grid, the compensation capacitor 212 can emit a capacitive reactive current to compensate for the inductive reactive current consumed by the inductive loads (such as motors, transformers, etc.) in the power grid. This helps to reduce the phase difference between the system voltage and current, thereby improving the power factor of the power grid. The improvement of the power factor means that the proportion of active power in the power grid increases, which helps to improve the efficiency and stability of the power grid.

[0044] See also Fig.11 As shown, as a preferred technical solution of this embodiment, the rotating member 213 includes: a rotating sleeve 2131, which is installed inside the rotating groove through a bearing, and the rotating sleeve 2131 is a cylindrical hollow structure, and a polygonal groove is arranged inside the rotating sleeve 2131; a rotating gear 2132, which is installed in the middle part of the outer side of the rotating sleeve 2131, and the inner concave surfaces of the connecting frame 211 and the main body 20 are both provided with coaxial annular grooves, and the adjacent annular grooves are connected to each other, and one side of the rotating gear 2132 is exposed in the annular groove; a telescopic rod 2133, which is a T-shaped structure, and a slider matching the polygonal groove is arranged on the inner side of the telescopic rod 2133, and a reset spring is arranged on the telescopic rod 2133.

[0046] In the above technical solution, when the driving unit 23 is working, the driving unit 23 will first squeeze the limiting rod 2142, so that the limiting rod 2142 will move outward, and the limiting rod 2142 can then drive the locking teeth to separate from the ratchet 2141, and then the driving unit 23 drives the rotating sleeve 2131 to rotate. When the driving unit 23 is separated from the rotating sleeve 2131, the driving unit 23 will also be separated from the limiting rod 2142 at the same time, and the limiting rod 2142 will quickly recover and drive the locking block 2143 to lock the ratchet 2141 to prevent the rotating sleeve 2131 from rotating.

[0048] In the above technical solution, when the telescopic rod 2133 rotates synchronously with the guide sleeve 2151, the telescopic rod 2133 is slidably arranged inside the guide sleeve 2151, so that the telescopic rod 2133 rotates synchronously, and an inclined sliding groove is arranged on the telescopic rod 2133. At the limit of the guide rod 2152, the telescopic rod 2133 moves inward or outward when rotating, so that the telescopic rod 2133 can drive the contact electrode 2153 to accurately contact the power connection unit 22.

[0049] It should be noted that the contact electrode 2153 is made of conductive material, and the upper end of the contact electrode 2153 is made of metal elastic material. Even if the contact electrode 2153 is worn out after long-term use, the contact electrode 2153 will still be in contact with the power connection unit 22 to ensure that the compensation capacitor 212 can be accurately put into or removed from the power grid.

[0050] See also Figure 5-Figure 7 As shown, as a preferred technical solution of this embodiment, the power connection unit 22 includes: an insulating seat 221, which is installed inside the circular groove; a positive pole power connection terminal 222, which is a C-shaped structure, and the positive pole power connection terminal 222 is installed at the upper end inside the circular groove; a negative pole power connection terminal 223, which is a C-shaped structure, and the negative pole power connection terminal 223 is installed at the lower end inside the circular groove, the input interface 31 is connected to one end of the positive pole power connection terminal 222 and the negative pole power connection terminal 223, and the output interface 32 is connected to the other end of the positive pole power connection terminal 222 and the negative pole power connection terminal 223.

[0051] In the above technical solution, a ring-shaped power connection interval is formed between the positive power connection terminal 222 and the negative power connection terminal 223. By respectively contacting the positive and negative poles of the compensation capacitor 212 with the positive power connection terminal 222 and the negative power connection terminal 223, the compensation capacitor 212 can be connected in parallel to the power grid. By controlling the number of compensation capacitors 212 that are put into or removed, the function of accurately adjusting the stability of the power grid can be achieved.

[0052] See also Figure 7 As shown, as a preferred technical solution of this embodiment, the positive terminal 222 and the negative terminal 223 are in a C-shaped structure, the inner side of the positive terminal 222 and the negative terminal 223 are conductive metal layers, and reinforcing ribs are evenly arranged on the outer side of the positive terminal 222 and the negative terminal 223.

[0053] In the above technical solution, the outer ends of the positive power connection terminal 222 and the negative power connection terminal 223 are made of insulating material, preferably a ceramic substrate, a C-shaped groove is provided on the inner side of the ceramic substrate, and the conductive metal layer is installed inside the C-shaped groove; when the power connection member 215 expands outward, the power connection member 215 can accurately contact the conductive metal layer, so that the compensation capacitor 212 can be accurately connected in parallel to the power grid.

[0054] See also Fig.14 As shown, as a preferred technical solution of this embodiment, the driving unit 23 includes: an electric turntable 231, which is in a circular ring structure and is installed on the inner wall of the circular ring groove; a rotating frame 232, which is installed on the electric turntable 231, and the electric turntable 231 is used to drive the rotating frame 232 to reciprocate inside the circular ring groove.

[0055] Continue reading Fig.14 As shown, as a preferred technical solution of this embodiment, the rotating frame 232 is an arc-shaped structure, and a rack plate 234 meshing with the rotating member 213 is arranged in the middle of the outer side surface of the rotating frame 232, and the rack plate 234 is slidably arranged in an annular groove on the inner concave surface of the connecting frame 211 and the main body 20, and extrusion blocks 233 are respectively arranged on the upper and lower sides of the outer side of the rotating frame 232, and inclined slopes are arranged at both ends of the extrusion block 233, and the extrusion block 233 cooperates with the limit member 214.

[0056] In the above technical solution, when the driving unit 23 rotates to cooperate with the rotating gear 2132, the rack plate 234 on the driving unit 23 slides inside the annular groove, and the rack plate 234 drives the rotating sleeve 2131 to rotate through the rotating gear 2132. When the rotating sleeve 2131 rotates, the telescopic rod 2133 inside the rotating sleeve 2131 expands outward under the action of the power connection piece 215, so that the power connection piece 215 can contact with the power connection unit 22, and the reset spring is in a stretched state. When the driving unit 23 is separated from the rotating gear 2132, the limiter 214 quickly rotates the rotating sleeve 2131 to prevent the rotating sleeve 2131 from rotating, so that the power connection piece 215 can always maintain power connection with the power connection unit 22.

[0057] It should be noted that when it is necessary to reduce the compensation capacitor 212 connected to the power grid, the drive unit 23 rotates counterclockwise, and the drive unit 23 first squeezes the limit member 214 so that the limit member 214 will not be stuck with the rotating sleeve 2131. Then the rack plate 234 drives the rotating gear 2132 to reverse, so that the rotating sleeve 2131 can drive the power connection member 215 to move inward, and the reset spring is restored, so that the compensation capacitor 212 can be cut off.

[0058] In the above technical solution, when the electric turntable 231 drives the rotating frame 232 to rotate clockwise inside the annular groove, the extrusion block 233 on the rotating frame 232 first contacts the limit member 214, so that the limit member 214 does not contact the rotating member 213, and then the rack plate 234 on the inner side of the rotating frame 232 will engage with the rotating member 213, and the rack plate 234 will drive the rotating member 213 to rotate, so that the rack plate 234 can drive the power connection member 215 to expand outward and be electrically connected to the power connection unit 22, thereby realizing the function of putting the compensation capacitor 212 into the power grid; by controlling the rotation angle of the rotating frame 232 inside the annular groove, the function of connecting the compensation capacitors 212 one by one in parallel to the power grid can be realized.

[0059] When the electric turntable 231 drives the rotating frame 232 to rotate counterclockwise inside the annular groove, the rotating frame 232 squeezes the limit member 214 again, so that the limit member 214 does not contact the rotating member 213. After that, the rack plate 234 on the inner side of the rotating frame 232 engages with the rotating member 213, and the rack plate 234 drives the power connection member 215 to move inward through the rotating member 213, so that the power connection member 215 is separated from the power connection unit 22, thereby realizing the function of cutting off the compensation capacitor 212 from the power grid.

[0060] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
