Technical Field
[0001] This invention relates to the field of insulating partitions, and particularly to an insulating partition for a low-voltage outgoing switch in a power distribution network. Background Technology
[0002] Currently, when carrying out power outage construction on low-voltage distribution outgoing lines, due to the close proximity of adjacent low-voltage switches, the permissible grounding on the outgoing line side must be grounded at the first outdoor pole or outdoor cable head. This requires maintenance personnel to operate from the ground to the pole for voltage testing and grounding, which involves a large work span, causing many inconveniences for maintenance personnel and making it easy to go to the wrong interval, posing a significant safety risk. If maintenance or replacement of outgoing cables is required, all outgoing lines need to be de-energized, expanding the power outage area and affecting power supply reliability and user satisfaction.
[0003] Therefore, it is necessary to propose an insulating partition for low-voltage outgoing switches in distribution networks to solve the above problems. Summary of the Invention

Adapter slots are symmetrically formed on the front and back of the top of the power distribution cabinet support. Guide blocks are symmetrically fixedly connected to the center of the left side of the inner cavity of the two adapter slots. Slots are symmetrically formed in the center of the inner cavity of the two guide blocks. First insulating partitions are symmetrically arranged on the front and back of the outgoing switch. Sliding grooves are formed at the bottom of the left side of the two first insulating partitions. Sliding blocks are symmetrically arranged at the bottom of the inner cavity of the two sliding grooves. Telescopic columns are symmetrically fixedly connected to the right side of the two sliding blocks. First springs are symmetrically arranged around the perimeter of the two telescopic columns. A locking block is fixedly connected to the bottom of the first spring. An inclined surface is formed at the bottom of the left side of the locking block. Guide grooves are symmetrically formed at the bottom of the left side of the two first insulating partitions. On the back side, rotating columns are symmetrically arranged on the left and right sides of the top front of the first insulating partition. The inner cavities of the two rotating columns are symmetrically threaded with second threaded columns. The top left side of the two first insulating partitions is symmetrically arranged with handles. The center right side of the two handles is symmetrically fixed with first threaded columns. The outer walls of the two first threaded columns are symmetrically arranged with movable blocks. The bottom of the two movable blocks is symmetrically fixed with second insulating partitions. The center right side of the two first insulating partitions is symmetrically provided with receiving grooves.
[0006] Preferably, the bottom of the first insulating partition is adapted to the size of the adapter slot, and the bottoms of the two first insulating partitions are inserted into the inner cavity of the distribution cabinet bracket through the adapter slot.
[0007] Preferably, the guide groove and the guide block are matched in size, the guide block is inserted into the inner cavity of the guide groove, the slot and the card block are matched in size, and the card block is inserted into the inner cavity of the guide block through the slot.
[0008] Preferably, the telescopic column is fixedly connected to the left side of the inner cavity of the first insulating partition, the top of the first spring is fixedly connected to the left side of the inner cavity of the first insulating partition, the guide groove communicates with the inner cavity of the slide groove, the locking block is movably connected in the inner cavity of the guide groove and the slide groove, the slider and the slide groove are matched in size, and the slider is movably connected to the left side of the first insulating partition through the slide groove.
[0009] Preferably, the back sides of the two rotating columns are symmetrically rotatably connected to the left and right sides of the top front side of the first insulating partition on the back side, and the front sides of the two second threaded columns are symmetrically fixedly connected to the left and right sides of the top back side of the first insulating partition on the front side.
[0010] Preferably, the two first threaded posts are symmetrically rotatably connected to the top of the inner cavities of the two first insulating partitions, the movable block is movably connected to the top of the inner cavity of the first insulating partition, and the movable block is threadedly connected to the outer wall of the first threaded posts.
[0011] Preferably, the second insulating partition is movably connected to the right side of the inner cavity of the first insulating partition via a receiving groove.
[0012] Preferably, a limiting block is symmetrically and movably connected to the center of the two opposite sides of the two first insulating partitions, and a handle groove is symmetrically opened in the center of the two limiting blocks on opposite sides. A through groove is symmetrically opened in the center of the two first insulating partitions on opposite sides, and a cylinder is symmetrically and fixedly connected in the center of the two limiting blocks on opposite sides. The cylinder is movably connected in the inner cavity of the first insulating partition through the through groove.
[0013] Preferably, a second spring is symmetrically fixedly connected to the left and right sides of the opposite side of the two limiting blocks.

The opposite sides of the two clamping blocks are symmetrically attached to the front and back of the outgoing switch.
[0014] Beneficial effects Compared with the prior art, the present invention provides an insulating partition for a low-voltage outgoing switch in a distribution network, which has the following advantages: The insulating partition of the low-voltage outgoing switch in this distribution network can be adjusted by rotating a rotating column, which allows the inner cavity of the rotating column to rotate on the outer wall of the second threaded column. This allows the spacing between the two first insulating partitions to be adjusted to fit the size of the distribution cabinet bracket. By rotating a handle, the first threaded column can be rotated. When the first threaded column rotates, a movable block can move on the outer wall of the first threaded column, which in turn moves the second insulating partition. At this time, the second insulating partition can move left and right through the receiving groove, which can be adjusted according to the size of the outgoing switch, thus lengthening the insulating partition.
[0015] The insulating partition of the low-voltage outgoing switch of the distribution network has an adapter slot, which allows the bottom of the first insulating partition to be inserted into the inner cavity of the distribution cabinet bracket. The guide slot allows the guide block to be inserted into the inner cavity of the first insulating partition. After the guide block enters the inner cavity of the guide slot, the inclined surface pushes the block upward. When the guide block is fully inserted into the inner cavity of the guide slot, the first spring presses the block down, thus locking the block into the inner cavity of the slot, thereby fixing the first insulating partition.
[0016] The insulating partition of the low-voltage outgoing switch of the distribution network has a sliding groove that allows the slider to move up and down in its inner cavity. When the slider is moved upward, it can drive the telescopic column to retract, thereby driving the locking block to leave the inner cavity of the locking groove. At this time, the first insulating partition can be removed from the distribution cabinet bracket.
[0017] The insulating partition of the low-voltage outgoing switch of this distribution network, through the setting of the second spring, will push the two second springs against the front and back of the outgoing switch under normal conditions, which can increase the fixing effect of the first insulating partition and prevent the first insulating partition from shaking during operation. By pulling the set handle groove, the limit block can be pulled outward, thereby removing the clamping block from the outer wall of the outgoing switch.
[0018] This low-voltage outgoing switch insulation partition in the distribution network ensures the safety of construction personnel, reduces unnecessary power outages for non-working users, and significantly shortens the operation time for maintenance personnel, reducing the risk of incorrect operation. This device can be applied to all outgoing switches in the current distribution network, and its application prospects are very broad.
[0019] The insulating partitions of the low-voltage outgoing switch of the distribution network, the first insulating partition and the second insulating partition are mainly made of polyester synthetic material, which has good electrical insulation performance, and has the advantages of high temperature resistance, moisture resistance and strong bending force. The insulating partitions are fixed by the matching distribution cabinet bracket, which is convenient and quick to install. After installation, they are firm and can achieve the effect of "hard isolation" of equipment. Attached Figure Description

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0023] like Figure 1-7As shown, an insulating partition for a low-voltage outgoing switch in a power distribution network includes a power distribution cabinet bracket 1. An outgoing switch 2 is fixedly connected to the center of the top of the power distribution cabinet bracket 1. Adaptor grooves 3 are symmetrically opened on the front and back of the top of the power distribution cabinet bracket 1. Guide blocks 4 are symmetrically fixedly connected to the center of the left side of the inner cavity of the two adapter grooves 3. Slots 5 are symmetrically opened in the center of the inner cavity of the two guide blocks 4. First insulating partitions 6 are symmetrically arranged on the front and back of the outgoing switch 2. Slide grooves 7 are opened at the bottom of the left side of the two first insulating partitions 6. Slider blocks 8 are symmetrically arranged at the bottom of the inner cavity of the two slide grooves 7. Telescopic columns 9 are symmetrically fixedly connected to the right side of the two sliders 8. First springs 10 are symmetrically arranged around the perimeter of the two telescopic columns 9. A locking block 11 is fixedly connected to the bottom of the first spring 10. A sloping surface 12 is provided at the bottom left side of the first insulating partition 6. Guide grooves 13 are symmetrically provided at the bottom left side of the two first insulating partitions 6. Rotating pillars 19 are symmetrically arranged on the left and right sides of the top front of the first insulating partition 6 on the back side. Second threaded pillars 20 are symmetrically threaded onto the front front of the inner cavity of the two rotating pillars 19. Handles 14 are symmetrically arranged at the top left side of the two first insulating partitions 6. First threaded pillars 15 are symmetrically fixedly connected to the center right side of the two handles 14. Movable blocks 16 are symmetrically arranged on the outer walls of the two first threaded pillars 15. Second insulating partitions 17 are symmetrically fixedly connected to the bottom of the two movable blocks 16. Receiving grooves 18 are symmetrically provided in the center right side of the two first insulating partitions 6. The bottom of the first insulating partition 6 matches the size of the matching groove 3. The bottom of the first insulating partition 6 is inserted into the inner cavity of the distribution cabinet bracket 1 through the adapter groove 3. The guide groove 13 and the guide block 4 are matched in size, and the guide block 4 is inserted into the inner cavity of the guide groove 13. The slot 5 and the locking block 11 are matched in size, and the locking block 11 is inserted into the inner cavity of the guide block 4 through the slot 5. The telescopic column 9 is fixedly connected to the left side of the inner cavity of the first insulating partition 6. The top of the first spring 10 is fixedly connected to the left side of the inner cavity of the first insulating partition 6. The guide groove 13 communicates with the inner cavity of the slide groove 7. The locking block 11 is movably connected to the inner cavity of the guide groove 13 and the slide groove 7. The slider 8 and the slide groove 7 are matched in size, and the slider 8 is movably connected to the left side of the first insulating partition 6 through the slide groove 7. The back sides of the two rotating columns 19 are symmetrically rotated and connected to the back side of the first insulating partition 6. On the left and right sides of the top front of the first insulating partition 6, two second threaded posts 20 are symmetrically fixedly connected to the top back of the first insulating partition 6 on the left and right sides. Two first threaded posts 15 are symmetrically rotatably connected to the top of the inner cavity of the two first insulating partitions 6. A movable block 16 is movably connected to the top of the inner cavity of the first insulating partition 6 and is threaded to the outer wall of the first threaded post 15. The second insulating partition 17 is movably connected to the right side of the inner cavity of the first insulating partition 6 through a receiving groove 18. Limiting blocks 21 are symmetrically and movably connected to the center of the opposite side of the two first insulating partitions 6. Handle grooves 22 are symmetrically opened in the center of the opposite side of the two limiting blocks 21. Through grooves 23 are symmetrically opened in the center of the opposite side of the two first insulating partitions 6.Two cylinders 24 are symmetrically fixedly connected to the center of opposite sides of the two limiting blocks 21. The cylinders 24 are movably connected to the inner cavity of the first insulating partition 6 via a through slot 23. Second springs 25 are symmetrically fixedly connected to the left and right sides of opposite sides of the two limiting blocks 21. The opposite sides of the second springs 25 are symmetrically fixedly connected to the left and right sides of opposite sides of the inner cavities of the two first insulating partitions 6. A clamping block 26 is symmetrically fixedly connected to the opposite side of the two cylinders 24. The clamping block 26 is larger than the through slot 23, and the opposite sides of the two clamping blocks 26 are symmetrically attached to the front and back of the outlet switch 2.
[0024] By rotating the rotating column 19, the inner cavity of the rotating column 19 can rotate on the outer wall of the second threaded column 20, thereby adjusting the gap between the two first insulating partitions 6 to fit the size of the distribution cabinet bracket 1. By rotating the handle 14, the first threaded column 15 can be rotated. When the first threaded column 15 rotates, the movable block 16 can move on the outer wall of the first threaded column 15, thereby moving the second insulating partition 17. At this time, the second insulating partition 17 can move left and right through the receiving groove 18, so that the second insulating partition 17 can be adjusted according to the size of the outgoing switch 2. The first insulating partition 6 is lengthened by adjusting the length of the insulating partition. The bottom of the first insulating partition 6 can be inserted into the inner cavity of the distribution cabinet bracket 1 via the adapter slot 3. The guide block 4 can be inserted into the inner cavity of the first insulating partition 6 via the guide slot 13. After the guide block 4 enters the inner cavity of the guide slot 13, the inclined surface 12 pushes the locking block 11 upwards. When the guide block 4 is fully inserted into the inner cavity of the guide slot 13, the first spring 10 presses down the locking block 11, thus locking it into the inner cavity of the locking slot 5. This completes the fixation of the first insulating partition 6. The sliding groove 7 allows the slider 8 to move up and down within its inner cavity. Moving the slider 8 upwards causes the telescopic column 9 to retract, thereby causing the locking block 11 to disengage from the inner cavity of the slot 5. At this point, the first insulating partition 6 can be removed from the distribution cabinet bracket 1. The second springs 25, normally positioned, push against the front and back of the outlet switch 2, increasing the fixation of the first insulating partition 6 and preventing it from wobbling during operation. Pulling the handle groove 22 pulls the limit block 21 outwards, thereby removing the clamping block 26 from the outlet switch 2. With the outer wall removed, this device ensures the safety of construction personnel, reduces unnecessary power outages for non-working users, and significantly shortens the operation time for maintenance personnel, reducing the risk of incorrect operation. This device can be applied to all outgoing switches in the current distribution network, with a very broad application prospect. The first insulating partition 6 and the second insulating partition 17 are mainly made of polyester synthetic material, which has good electrical insulation performance and advantages such as high temperature resistance, moisture resistance, and strong bending force. The insulating partition is fixed by the matching distribution cabinet bracket 1, which is convenient and quick to install and is firm after installation, achieving the effect of "hard isolation" of the equipment.
[0025] It should be noted that this invention is an insulating partition for a low-voltage outgoing switch in a power distribution network. In use, the first insulating partition 6 is adjusted according to the dimensions of the distribution cabinet bracket 1 and the outgoing switch 2. Rotating the rotating column 19 adjusts the distance between the two first insulating partitions 6. Rotating the handle 14 rotates the first threaded column 15, which in turn moves the movable block 16 left and right on its outer wall. The movable block 16 then moves the second insulating partition 17, thereby positioning it to fit the dimensions of the outgoing switch 2. The bottom of the first insulating partition 6 is inserted into the inner cavity of the distribution cabinet bracket 1 through the adapter slot 3. The first insulating partition 6 is moved to the left side of the inner cavity of the adapter slot 3. At this time, the guide block 4 will enter the inner cavity of the guide slot 13. At this time, the right side of the guide block 4 will move the locking block 11 to the top through the inclined surface 12. When the guide block 4 is fully inserted into the inner cavity of the guide slot 13, the first spring 10 will push the locking block 11 downward, so that the locking block 11 can be locked into the inner cavity of the locking slot 5. At this time, the first insulating partition 6 is fixed, and the staff can start working.
