Description

Technical Field

[0001] The present invention relates to the technical field of distribution model decoupling, and in particular to a multi-conductor decoupling device and a decoupling method applied to an equivalent model of a distribution network cable. Background Art

[0002] The current transmission media of the distribution network are mainly overhead lines, buried cables, and their series-parallel lines. In order to facilitate the control of the connection state between multiple conductors, a decoupling device needs to be set between multiple conductors. In order to detect the operation stability and durability of decoupling devices of different specifications, it is necessary to detect through an equivalent model at the beginning of production and assembly. However, the current equivalent model can only simulate a decoupling device of a single specification, and the models of different specifications need to be completely disassembled before re-simulating the experiment, which results in low experimental efficiency, high experimental cost and difficulty, and limited detection values for a single experiment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the current equivalent model has low experimental efficiency, high experimental cost and difficulty, and limited detection values for a single experiment.

Side conductive rods are threadedly assembled inside the upper first installation blind holes and the upper second installation blind holes, and a middle electric control adjustment rod is threadedly assembled inside the upper third installation blind hole. The upper ends of the side conductive rods are movably assembled with side turning connecting arms, and the upper end of the middle electric control adjustment rod is movably assembled with a top electric control control module.

[0005] The top electric control control module includes an electric control horizontal rotation mechanism, an electric control vertical turning mechanism, and a modular decoupling claw installed at the top of the electric control vertical turning mechanism.

[0006] Internal thread metal seats are fixedly assembled inside the upper first installation blind holes and the upper second installation blind holes, and an internal thread insulating seat is fixedly installed inside the upper third installation blind hole.

[0007] Internal thread communication blind holes are opened on the upper surface of the ground loading platform around the upper first installation blind holes and the upper second installation blind holes. An upper metal sheet and a lower metal sheet connected to the inside of the internal thread communication blind holes are fixedly assembled inside the ground loading platform, and an insulating bolt is threadedly inserted into the internal thread communication blind holes.

[0008] The electric control lateral rotation mechanism includes a middle-mounted assembly rod axially inserted on a middle-mounted electric control adjusting rod, a side-mounted bottom mounting seat fixed outside the middle-mounted electric control adjusting rod, a bottom-mounted motor fixed on the side wall of the side-mounted bottom mounting seat, a bottom-mounted worm gear mounted on the adjusting shaft of the bottom-mounted motor, and a bottom-mounted worm wheel fixed on the side wall of the middle-mounted assembly rod.

[0009] An upper-side flipping groove is formed at the upper end of the outer side surface of the middle-mounted assembly rod. The electric control longitudinal flipping mechanism includes a side-mounted top mounting seat fixed on the outer side surface of the middle-mounted assembly rod, a top-mounted motor fixed on the side wall of the side-mounted top mounting seat, a lateral adjusting disc arranged inside the upper-side flipping groove, a plurality of lateral adjusting arms fixed on the outer side of the lateral adjusting disc, and a top-mounted gear for drivingly connecting the top-mounted motor and the lateral adjusting disc.

[0010] Non-circular side-mounted mounting jacks are formed at the outer ends of the lateral adjusting arms, and lateral locking bolts for fixing modular decoupling claws are threadedly assembled on the outer side surfaces of the lateral adjusting arms.

[0011] A top-side flipping groove is formed at the upper end of the side-mounted conductive rod side wall. A lateral assembly through hole is formed inside the top-side flipping groove. The side-mounted flipping connecting arm is movably assembled with the top-side flipping groove through a lateral locking screw penetrating the lateral assembly through hole. A lateral fixing bolt is threadedly sleeved on the lateral locking screw outside the side-mounted conductive rod.

[0012] Lateral flipping brackets for externally connecting optical detection probes are assembled on both sides of the upper end of the ground loading platform at the assembly ends of the side-mounted flipping connecting arm and the top-mounted electric control module.

[0013] A multi-conductor decoupling method applied to an equivalent model of a distribution network cable. Metal terminals protruding upward are fixed on both side walls of the ground loading platform. They are fixed on the metal terminals through external power supply bolts. Then, by screwing an insulating bolt at a specified position into the internal threaded blind hole, the upper metal sheet inside is pressed downward to fit with the upper surface of the lower metal sheet. At this time, the metal terminal will transmit power to the inside of the side-mounted conductive rod through the lower metal sheet and the upper metal sheet, and then supply power to the side-mounted flipping connecting arm. A metal sheet matching the modular decoupling claw is detachably fixed at the top end of the side-mounted flipping connecting arm. Then, the top-mounted electric control module at the upper end of the middle-mounted electric control adjusting rod adjusts different specifications of modular decoupling claws to the horizontal through longitudinal flipping, and then performs lateral flipping. The modular decoupling claw is sleeved outside the metal sheet. Then, the states during the coupling process are recorded by the optical detection probes on both sides.

Then, it adjusts different specifications of modular decoupling claws to the horizontal through longitudinal flipping again, and then performs lateral flipping. The modular decoupling claw is sleeved outside the metal sheet. Then, the states during the coupling process are recorded by the optical detection probes on both sides. In this way, experiments on decoupling equivalent models of different specifications can be completed.

[0031] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A multi-conductor decoupling device applied to a distribution network cable equivalent model as shown in

[0032] includes a ground-mounted platform 1. On the upper surface of the ground-mounted platform 1, there are provided 2 upper first mounting blind holes 2, 2 upper second mounting blind holes 3, and 1 upper third mounting blind hole 4. Side-mounted conductive rods 5 are threadedly assembled inside the upper first mounting blind holes 2 and the upper second mounting blind holes 3, and a middle-mounted electric control adjusting rod 6 is threadedly assembled inside the upper third mounting blind hole 4. A side-mounted flipping connecting arm 7 is movably assembled at the upper end of the side-mounted conductive rod 5, and a top-mounted electric control control module 8 is movably assembled at the upper end of the middle-mounted electric control adjusting rod 6.

[0033] For the sake of cooperating with threaded assembly and metal conduction, internal threaded metal seats 9 are fixedly assembled inside both the upper first mounting blind holes 2 and the upper second mounting blind holes 3, and an internal threaded insulating seat is fixedly installed inside the upper third mounting blind hole 4.

[0034] For the convenience of controlling the on-off state, internal threaded connecting blind holes 10 are provided on the upper surface of the ground-mounted platform 1 around the upper first mounting blind holes 2 and the upper second mounting blind holes 3. An upper metal sheet 11 and a lower metal sheet 12 that are connected to the inside of the internal threaded connecting blind holes 10 are fixedly assembled inside the ground-mounted platform 1, and an insulating bolt 13 is threadedly inserted into the internal threaded connecting blind holes 10.

[0035] When the insulating bolt 13 is screwed into the internal threaded connecting blind holes 10, it will squeeze the upper metal sheet 11 from top to bottom, connecting the upper metal sheet 11 and the lower metal sheet 12, thus facilitating the series connection of the outer metal terminal 18 and the side-mounted flipping connecting arm 7 at the upper end of the side-mounted conductive rod 5.

[0036] The internal-thread metal seat 9 is connected to the upper metal sheet 11 through the upper conductive circuit inside the ground load platform 1, while the lower metal sheet 12 is connected to the metal terminal 18 on the corresponding side of the ground load platform 1 through the lower conductive circuit inside the ground load platform 1.

[0037] To cooperate with the horizontal rotation adjustment, the electric control horizontal rotation mechanism 81 includes a middle-mounted assembly rod 811 axially inserted on the middle-mounted electric control adjusting rod 6, a side-mounted bottom mounting seat 812 fixed outside the middle-mounted electric control adjusting rod 6, a bottom-mounted motor 813 fixed on the side wall of the side-mounted bottom mounting seat 812, a bottom-mounted worm 814 mounted on the adjusting shaft of the bottom-mounted motor 813, and a bottom-mounted worm gear 815 fixed on the side wall of the middle-mounted assembly rod 811.

[0038] The bottom-mounted motor 813 controls the rotation of the bottom-mounted worm 814, and then the bottom-mounted worm 814 meshes with the bottom-mounted worm gear 815 for transmission. Then the bottom-mounted worm 814 controls the rotation of the bottom-mounted worm gear 815, and drives the middle-mounted assembly rod 811 to rotate through the bottom-mounted worm gear 815, so as to control the decoupling operation.

[0039] To cooperate with the upper flipping adjustment, an upper-side flipping groove 14 is formed at the upper end of the outer side surface of the middle-mounted assembly rod 811. The electric control longitudinal flipping mechanism 82 includes a side-mounted top mounting seat 821 fixed on the outer side surface of the middle-mounted assembly rod 811, a top-mounted motor 822 fixed on the side wall of the side-mounted top mounting seat 821, a lateral adjusting disc 823 arranged inside the upper-side flipping groove 14, four lateral adjusting arms 824 fixed outside the lateral adjusting disc 823, and a top-mounted gear 825 for drivingly connecting the top-mounted motor 822 and the lateral adjusting disc 823.

[0040] The top-mounted gear 825 is axially fixed on the adjusting shaft of the top-mounted motor 822. The top-mounted motor 822 controls the rotation of the top-mounted gear 825, thereby controlling the rotation of the lateral adjusting disc 823, changing the angle of the lateral adjusting arms 824, and then switching the modular decoupling claws 83 of different specifications.

[0041] To cooperate with the installation and fixation, non-circular side-mounted installation jacks are formed at the outer ends of the lateral adjusting arms 824, and lateral locking bolts 826 for fixing the modular decoupling claws 83 are threadedly assembled on the outer side surfaces of the lateral adjusting arms 824.

[0042] The modular decoupling claw 83 is axially assembled with the outer end of the lateral adjusting arm 824 by inserting the installation insert block into the non-circular side-mounted installation jack, and then the modular decoupling claw 83 is fixed and locked by screwing the lateral locking bolt 826 into it.

[0043] To facilitate lateral assembly, storage, and angle adjustment, a top-side flipping groove 15 is provided at the upper end of the sidewall of the side-mounted conductive rod 5. A lateral assembly through-hole is provided inside the top-side flipping groove 15. The side-mounted flipping connecting arm 7 is movably assembled with the top-side flipping groove 15 through a lateral locking screw passing through the lateral assembly through-hole. A lateral fixing bolt 16 is threadedly sleeved on the lateral locking screw outside the side-mounted conductive rod 5.

[0044] The side-mounted conductive rods 5 are evenly distributed on both sides of the middle-mounted electric control adjusting rod 6 with the middle-mounted electric control adjusting rod 6 as the center, which can ensure that the side-mounted flipping connecting arms 7 can cooperate smoothly with the modular decoupling claws 83 during the simulation test.

[0045] To cooperate with lateral assembly and record the decoupling process from both sides, lateral flipping brackets 17 for externally connecting optical detection probes are assembled on both sides of the upper end of the ground-mounted platform 1 at the assembly ends of the side-mounted flipping connecting arms 7 and the top-mounted electric control module 8.

[0046] Lateral storage grooves for facilitating the flipping of the lateral flipping brackets 17 are provided on the front and rear sides of the ground-mounted platform 1. In this way, the external space occupation can be reduced during storage. The lateral flipping brackets 17 are movably assembled with the ground-mounted platform 1 by inserting the mounting shafts on one side of the connecting ends into the lateral storage grooves. Then, when the lateral flipping brackets 17 are flipped upward, the elastic buckles at the ends penetrate downward into the positioning holes inside the lateral storage grooves, thereby locking the angles of the lateral flipping brackets 17.

[0047] A multi-conductor decoupling method applied to the equivalent model of the distribution network cable. Metal terminals 18 protruding upward are fixed on both sidewalls of the ground-mounted platform 1 and are fixed on the metal terminals 18 through external power supply bolts. Then, by screwing the insulating bolt 13 at the specified position into the internal threaded communication blind hole 10, the upper metal sheet 11 inside is pressed downward to fit with the upper surface of the lower metal sheet 12. At this time, the metal terminal 18 will transmit power to the inside of the side-mounted conductive rod 5 through the lower metal sheet 12 and the upper metal sheet 11, and then supply power to the side-mounted flipping connecting arm 7. A metal sheet matching the modular decoupling claw 83 is detachably fixed at the top of the side-mounted flipping connecting arm 7. Then, the top-mounted electric control module 8 at the upper end of the middle-mounted electric control adjusting rod 6 adjusts different specifications of the modular decoupling claws 83 to the horizontal through longitudinal flipping, and then performs lateral flipping to sleeved the modular decoupling claws 83 outside the metal sheet. Then, the states during the coupling process are recorded by the optical detection probes on both sides. Then, the top-mounted electric control module 8 performs reverse lateral flipping to separate the modular decoupling claws 83 from the metal sheet. Then, different specifications of the modular decoupling claws 83 are adjusted to the horizontal through longitudinal flipping, and then lateral flipping is performed again to sleeved the modular decoupling claws 83 outside the metal sheet. Then, the states during the coupling process are recorded by the optical detection probes on both sides. In this way, experiments on different specifications of decoupling equivalent models can be completed.
