Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a terminal compensation device for a distribution network. Background Art

[0002] The distribution network is composed of overhead lines, cables, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities. It plays an important role in distributing electric energy in the power grid. When it is used for terminal power supply, the electric energy is lost due to the transformation and other effects. It is necessary to use terminal compensation devices for reactive power compensation to reduce the loss of power supply transformers and transmission lines, improve power supply efficiency and improve the power supply environment.

[0003] For example, the terminal compensation device for a distribution network disclosed in authorization publication number CN220652983U comprises a support block, a connecting plate, and a capacitor. A limit bar is fixed to one side of the longitudinal centerline of the top of the support block. A capacitor is positioned near the limit bar on the side of the longitudinal centerline of the top of the support block. A connecting plate is positioned above the capacitor. Active power connection blocks are symmetrically fixed within the connecting plate along the transverse centerline. The active power connection blocks are fixed through the connecting plate. By adopting the above technical solution, the present invention has the beneficial effect of resolving the problem of inconvenient replacement of damaged capacitors during operation of the terminal compensation device for a distribution network.

[0004] Although the above patent can facilitate the replacement of capacitors, since the vertical spacing between the fixing bar and the support block cannot be adjusted, if another capacitor with a larger height is replaced, the above patent cannot be adapted for installation, resulting in great limitations in the scope of use.

[0024] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-4 As shown, the utility model provides a technical solution:

[0026] A terminal compensation device for a distribution network includes a mounting base 1, wherein a capacitor 2 is disposed inside the mounting base 1; a support plate 3 is disposed below the interior of the mounting base 1, and an adaption mechanism is provided between the support plate 3 and the four corners of the mounting base 1. The adaption mechanism includes a telescopic rod 5, which is fixedly mounted between the support plate 3 and the four corners of the mounting base 1, and a spring 6 is provided between the telescopic rod 5 and the outside of the support plate 3;

[0027] In this embodiment, the device has a support plate 3 movably installed at the lower part of the interior of the mounting base 1, and telescopic rods 5 are installed at the four corners of the support plate 3 and the mounting base 1. Springs 2 6 are installed on the outside of the telescopic rods 5 and the support plate 3. When the height of the capacitor 2 placed on the support plate 3 changes, the telescopic rods 5 and the springs 2 6 can cooperate to elastically adjust the vertical distance between the support plate 3 and the top plate 4, which is convenient for adapting to clamping support plates 3 of different heights.

[0028] like Figure 3As shown, a limiting mechanism is provided at the lower middle portion of the mounting base 1, and the limiting mechanism includes a sleeve 7, which is movably mounted at the middle portion of the bottom end of the mounting base 1. The internal thread of the sleeve 7 is connected to a screw rod 8, and a support plate 9 is fixedly mounted on the top end of the screw rod 8. Both ends of the support plate 9 are slidably connected to the inner wall of the mounting base 1, and the bottom end of the sleeve 7 passes through the mounting base 1 and is fixedly mounted with a hand wheel 10;

[0029] In this embodiment, after the support plate 3 lifts the capacitor 2 and shakes the handwheel 10, the handwheel 10 controls the rotation of the sleeve 7. When the sleeve 7 rotates, the two ends of the support plate 9 are slidably connected to the inner wall of the mounting base 1, so the support plate 9 guides the screw 8, causing the screw 8 to rise linearly. After the screw 8 rises linearly, it drives the support plate 9 to rise until the support plate 9 is supported under the support plate 3. In this way, when the support plate 3 is used to lift the capacitor 2, it has high stability and will not be affected by the spring 2 6.

[0030] like Figure 2 As shown, the top plate 4 is arranged above the interior of the mounting base 1, and a mounting mechanism is provided inside the top plate 4. The mounting mechanism includes a pull rod 11, which is movably sleeved on the inner middle part of the top plate 4. The pull rod 11 is located on the outer end of the top plate 4 and is fixedly installed with an insulating pull head 12. The pull rod 11 is located on the inner end of the top plate 4 and is provided with a connector 13. Connecting sleeves 14 are provided on both sides of the top of the capacitor 2. Both ends of the connector 13 are movably sleeved with the connecting sleeve 14. A spring 15 is provided between the connector 13 and the inner wall of the top plate 4. The mounting mechanism also includes a guide groove 16, which is symmetrically opened on both sides of the top of the mounting base 1. Joints 17 movably connected to the guide groove 16 are provided on both sides of the top of the connector 13, and a folded rubber belt 18 is provided between the guide groove 16 and both sides of the joint 17.

[0031] In this embodiment, before placing the capacitor 2 on the support plate 3, pull the insulating pull head 12, the insulating pull head 12 pulls the connector 13 outward through the pull rod 11, and compresses the spring 15, and then lifts the capacitor 2 on the support plate 3. At this time, the capacitor 2 is lifted by the support plate 3 and inserted into the top plate 4. Then release the insulating pull head 12, and the compressed spring 15 rebounds to control the connector 13 to retreat until the other two sides of the connector 13 are inserted into the two connecting sleeves 14 at the top of the capacitor 2, thereby achieving the purpose of facilitating quick installation.

[0032] Working principle: This device has a support plate 3 movably installed at the bottom of the interior of the mounting base 1. Telescopic rods 5 are installed at the four corners of the support plate 3 and the mounting base 1. Springs 6 are installed on the outside of the telescopic rods 5 and the support plate 3. When the height of the capacitor 2 placed on the support plate 3 changes, the telescopic rods 5 and the springs 6 can cooperate to elastically adjust the vertical distance between the support plate 3 and the top plate 4, which is convenient for adapting to the use of clamping support plates 3 of different heights. After the support plate 3 lifts the capacitor 2 and shakes the handwheel 10, the handwheel 10 controls the rotation of the sleeve 7. When the sleeve 7 rotates, the two ends of the support plate 9 are slidably connected to the inner wall of the mounting base 1, so the support plate 9 guides the screw 8. The screw rod 8 rises linearly, and after the screw rod 8 rises linearly, it drives the support plate 9 to rise until the support plate 9 is supported under the support plate 3. Before placing the capacitor 2 on the support plate 3, pull the insulating head 12. The insulating head 12 pulls the connector 13 outward through the pull rod 11 and compresses the spring 15, and then lifts the capacitor 2 on the support plate 3. At this time, the capacitor 2 is lifted by the support plate 3 and then lifted and stuck into the top plate 4. Then release the insulating head 12, and the compressed spring 15 rebounds to control the connector 13 to retreat until the other two sides of the connector 13 are stuck in the two connecting sleeves 14 at the top of the capacitor 2.
