Description

Technical Field

The connection between adjacent intervals usually adopts conductive rods in the form of finger contact to achieve busbar connection; specifically, the busbar shells of two intervals are connected by a docking flange, and three conductive rods are inserted into the two busbar shells and the docking flange. The first end of each conductive rod is plugged into the contact seat of the insulator installed on the first busbar shell, and the second end of each conductive rod is plugged into the contact seat of the insulator installed on the second busbar shell.

[0004] Due to the long length of the conductive rod, the current docking method of adjacent intervals is: when the first end of the conductive rod is plugged into the contact seat of the insulator installed on the first busbar housing, one person holds the conductive rod and the other plugs in; after the first ends of the three conductive rods are plugged into the contact seats of the three insulators installed on the first busbar housing, at least two people plug the second ends of the three conductive rods into the contact seats of the three insulators installed on the second busbar housing.

Step 7: first, plug the second flange seat 21 of the second spaced busbar housing 2 with the first guide positioning rod A31 of each first guide positioning assembly A3 and the second guide positioning rod A41 of each second guide positioning assembly A4, and then move the second spaced busbar housing 2 toward the direction close to the docking flange 3 until the second ends of the three conductive rods 4 are partially inserted into the second contact seats 221 of the three second insulators 22 installed on the second spaced busbar housing 2, and at this time, there is a gap between the second flange seat 21 of the second spaced busbar housing 2 and the locking plate A2 and the support plate A1; Step 8: first remove the first positioning nut A32 of each first guide positioning assembly A3 and the second positioning nut A42 of each second guide positioning assembly A4, then release the connection between the locking plate A2 and the supporting plate A1, and finally disassemble the locking plate A2 and the supporting plate A1;

[0037] Only one operator is required to perform all the steps of the docking method, which effectively saves labor. In addition, the present invention utilizes docking tool A to support the conductive rod 4 during the entire docking process to prevent the conductive rod 4 from sagging, thereby ensuring that the conductive rod 4 is quickly and accurately plugged into the first contact seat 121 of the first insulator 12 and the second contact seat 221 of the second insulator 22, so that the two intervals can be accurately and quickly docked.

[0040] In an embodiment of the present invention, the supporting groove A11 and / or the locking groove A21 may be provided with an elastic pad A6, which may increase the friction force on the conductive rod 4, thereby ensuring that the locking plate A2 and the supporting plate A1 may stably clamp the three conductive rods 4 and drive the three conductive rods 4 to move.

[0041] In an embodiment of the present invention, the first guide positioning assembly A3 may further include a first positioning sleeve A33 for sleeved on the first guide positioning rod A31. In step one, the first positioning sleeve A33 is sleeved on the first guide positioning rod A31 and the first positioning sleeve A33 is embedded in the first through hole 111 of the first flange seat 11 to prevent the first guide rod from shaking; and in step eight, after removing the first positioning nut A32 of each first guide positioning assembly A3 and the second positioning nut A42 of each second guide positioning assembly A4, and then removing each first positioning sleeve A33, each first guide positioning rod A31 and each second guide positioning rod A41 can be moved, thereby facilitating the subsequent disassembly of the locking plate A2 and the support plate A1.

Step nine: First, under the guidance of the first guide positioning rod of each first guide positioning assembly and the second guide positioning rod of each second guide positioning assembly, move the second interval busbar housing toward the docking flange until the second flange surface of the docking flange abuts against the second flange seat of the second interval busbar housing, so that the first ends of the three conductive rods are respectively fully inserted into the second contact seats of the three second insulators installed on the second interval busbar housing; then, connect the second flange surface of the docking flange and the second flange seat of the second interval busbar housing through a plurality of second fixing assemblies, the second fixing assembly comprising a second fixing bolt passing through a second through hole of the second flange surface and a second through hole of the second flange seat, and a second fixing nut threadedly connected to the second fixing bolt; then, remove the first guide positioning rod of each first guide positioning assembly and the second guide positioning rod of each second guide positioning assembly; finally, connect the second flange surface of the docking flange and the remaining part of the second flange seat of the second interval busbar housing that needs to be connected through the second fixing assembly.

7. The docking method according to claim 6, characterized in that: The method for disassembling the locking plate and the support plate includes: first removing the first guide positioning rod of each first guide positioning assembly, then removing the support plate, and then inserting the first guide positioning rod of each first guide positioning assembly into the second through hole of the second flange surface of the docking flange and the second through hole of the second flange seat of the second spacer busbar shell, and then removing the second guide positioning rod of each second guide positioning assembly, and then removing the locking plate, and finally inserting the second guide positioning rod of each second guide positioning assembly into the second through hole of the second flange surface of the docking flange and the second through hole of the second flange seat of the second spacer busbar shell.

8. The docking method according to claim 6, characterized in that: The method for disassembling the locking plate and the support plate includes: first removing the second guide positioning rod of each second guide positioning assembly, then removing the locking plate, and then inserting the second guide positioning rod of each second guide positioning assembly into the second through hole of the second flange surface of the docking flange and the second flange seat of the second spacer busbar housing, and then removing the first guide positioning rod of each first guide positioning assembly, and then removing the support plate, and finally inserting the first guide positioning rod of each first guide positioning assembly into the second through hole of the second flange surface of the docking flange and the second through hole of the second flange seat of the second spacer busbar housing.

9. The docking method according to claim 7, characterized in that: In step 1, a first positioning sleeve is sleeved on the first guide positioning rod and the first positioning sleeve is embedded in the first through hole of the first flange seat; In step eight, after removing the first positioning nuts of each first guide positioning assembly and the second positioning nuts of each second guide positioning assembly, each first positioning sleeve is then removed.
