[0002] Aluminum alloy bus duct is a highly efficient power transmission and distribution equipment widely used in industrial and commercial buildings. It consists of an aluminum alloy shell, a phase busbar (usually made of copper or aluminum), an insulating partition, an insulating material covering the busbar, and fasteners. The aluminum alloy shell not only has good conductivity and mechanical strength, but also has excellent heat dissipation performance and protection level. It can effectively prevent moisture and dust from entering, thereby improving the reliability and safety of the system.

[0003] In order to ensure the safe operation of aluminum alloy bus duct, strict insulation test must be carried out before leaving the factory. The insulation test mainly includes ground test and relative test to detect the aging and damage of the insulating material inside the bus duct and prevent potential safety accidents.

[0033] See also Figure 7 As shown, the driving mechanism includes a mounting plate 1401 and a fourth electric push rod 1402; the mounting plate 1401 is installed on the left side of the bottom of the connecting plate 7; the fourth electric push rod 1402 is arranged on the lower side of the mounting plate 1401, and the telescopic rod of the fourth electric push rod 1402 is connected to the second test probe 15.

[0034] When in use, the frame 1 is pushed to move, so that the first universal wheel 2 rolls on the ground, thereby driving the insulation test device to move to a specified position, so that the frame 1 is aligned with the stacked aluminum alloy bus duct (such as Figure 4As shown), the first electric slide rail 403 is then used to drive the connecting frame 5, the first electric push rod 6, the connecting plate 7, the insulating plate 8 and the positioning plate 9 to rise or fall, so that the insulating plate 8 and the positioning plate 9 are at the same height as the aluminum alloy bus duct to be tested, and then the servo motor 402 is used to drive the lead screw 401 to rotate forward or reverse, thereby driving the first electric slide rail 403, the connecting frame 5, the first electric push rod 6, the connecting plate 7, the insulating plate 8 and the positioning plate 9 to move left or right, so that the insulating plate 8 and the positioning plate 9 are aligned with the aluminum alloy bus duct to be tested, and the positions of the insulating plate 8 and the positioning plate 9 are adjusted accordingly, and then the first electric push rod 6 is used to drive the connecting plate 7, the insulating plate 8 and the positioning plate 9 to move forward until the rear plate-like structure of the positioning plate 9 contacts the conductive bar 102 of the aluminum alloy bus duct, and the conductive bar 10 2 is between the rear plate-like structure of the positioning plate 9 and the insulating plate 8, and then the telescopic rod of the second electric push rod 1001 is controlled to retract, so that the telescopic rod of the second electric push rod 1001 pulls the insulating plate 8 to the left through the spring 1002. When the insulating plate 8 contacts the conductive bar 102, the conductive bar 102 will block the movement of the insulating plate 8. When the telescopic rod of the second electric push rod 1001 continues to retract, the spring 1002 stretches. Under the elastic force of the spring 1002, the spring 1002 applies a pulling force to the insulating plate 8, so that the insulating plate 8 presses the conductive bar 102 against the rear plate-like structure of the positioning plate 9, so that the conductive bar 102 is in close contact with the rear plate-like structure of the positioning plate 9, thereby preventing the conductive bar 102 from having a poor contact with the rear plate-like structure of the positioning plate 9, and then proceed to the next step according to the test requirements: If it is necessary to perform a relative test on two adjacent conductive bars 102 in the aluminum alloy bus duct, the second electric slide rail 1201 drives the mounting frame 1202, the third electric push rod 1203 and the first test probe 13 to move left or right until the front and rear two first test probes 13 are respectively moved to the top of the front and rear two designated copper plates 11 (the positions of the two designated copper plates 11 need to be two of the two adjacent groups, and the two designated copper plates 11 cannot be in the same group), and then the third electric push rod 1203 drives the first test probe 13 to move downward, so that the first test probe 13 contacts the designated copper plate 11. In this way, the two The first test probes 13 are respectively in contact with two adjacent conductive bars 102 in the aluminum alloy bus duct, and then the megohmmeter 3 can be used to perform a relative test on the two adjacent conductive bars 102 in the aluminum alloy bus duct. After the relative test of the two adjacent conductive bars 102 in the aluminum alloy bus duct is completed, the third electric push rod 1203 is used to drive the first test probe 13 to move upward and reset, so that the first test probe 13 is separated from the specified copper plate 11, and then the above operation is repeated to perform a relative test on other adjacent two conductive bars 102 in the aluminum alloy bus duct, until all adjacent two conductive bars 102 in the aluminum alloy bus duct are relatively tested; If it is necessary to perform a ground test on the conductive bar 102 in the aluminum alloy bus duct, the second test probe 15 is driven to move forward by the fourth electric push rod 1402 until the second test probe 15 contacts the aluminum alloy shell 101 of the aluminum alloy bus duct, and then the corresponding mounting frame 1202, the third electric push rod 1203 and the first test probe 13 are driven to move left or right by the second electric slide rail 1201 on the front side until the first test probe 13 on the front side moves to just above the designated copper plate 11, and then the first test probe 13 is driven to move downward by the third electric push rod 1203 to contact the designated copper plate 11, and then the aluminum alloy bus duct can be tested by the megohmmeter 3. The conductive bar 102 in the aluminum alloy bus duct is tested for grounding. After the conductive bar 102 in the aluminum alloy bus duct has completed the grounding test, the third electric push rod 1203 is used to drive the first test probe 13 to move upward and reset, so that the first test probe 13 is separated from the specified copper plate 11. Then, the above operation is repeated to perform grounding tests on other conductive bars 102 in the aluminum alloy bus duct until all conductive bars 102 in the aluminum alloy bus duct have completed the grounding test. After all conductive bars 102 in the aluminum alloy bus duct have completed the grounding test, the fourth electric push rod 1402 is used to drive the second test probe 15 to move backward and reset, so that the second test probe 15 is separated from the aluminum alloy shell 101 of the aluminum alloy bus duct. When the above operation is completed, the insulation test of the specified aluminum alloy bus duct can be automatically completed, and then the telescopic rod of the second electric push rod 1001 is controlled to extend, during which the spring 1002 gradually returns to its original state. After the spring 1002 returns to its original state, the telescopic rod of the second electric push rod 1001 will pull the insulating plate 8 to the right through the spring 1002 to reset, so that the insulating plate 8 is separated from the conductive bar 102, and then the first electric push rod 6 drives the connecting plate 7, the insulating plate 8 and the positioning plate 9 to move backward and reset, so that the rear plate-like structure of the positioning plate 9 is separated from the conductive bar 102 of the aluminum alloy bus duct, and the conductive bar 102 leaves from between the rear plate-like structure of the positioning plate 9 and the insulating plate 8, and then repeat the above position adjustment operation of the insulating plate 8 and the positioning plate 9 until the insulating plate 8 and the positioning plate 9 are aligned with the next aluminum alloy bus duct to be tested, and then repeat the above operation, and the insulation test of the next aluminum alloy bus duct to be tested can be automatically repeated.

[0035] See also Figure 8 and Fig. 9As shown, a wiping mechanism is also included, which includes a fixed plate 16, a first sponge block 17 and a second sponge block 18; a fixed plate 16 is installed on the right side of the bottom of the connecting plate 7, and the fixed plate 16 is flush with the positioning plate 9; the left front part of the fixed plate 16 and the right front part of the leftmost positioning plate 9 are connected to the first sponge block 17, and the first sponge block 17 is connected to the front plate-like structure of the positioning plate 9; the front sides of the remaining four positioning plates 9 are connected to the second sponge block 18, and the second sponge block 18 is connected to the front plate-like structure of the positioning plate 9, and the second sponge block 18 is located between the two first sponge blocks 17, and the first sponge block 17 and the second sponge block 18 are both used to wipe the conductive bar 102.

[0036] When the connecting plate 7 and the positioning plate 9 move forward, the first sponge block 17 and the second sponge block 18 will first contact the conductive bar 102, and then as the connecting plate 7 and the positioning plate 9 continue to move, the first sponge block 17 and the second sponge block 18 will wipe the surface of the conductive bar 102 to clean the impurities on the surface of the conductive bar 102 to prevent the impurities on the surface of the conductive bar 102 from affecting the subsequent insulation test. When the first sponge block 17 and the second sponge block 18 continue to move forward, the first sponge block 17 and the second sponge block 18 will separate from the conductive bar 102, and the first sponge block 17 and the second sponge block 18 will contact the insulating sleeve on the surface of the conductive bar 102 (only the part of the conductive bar 102 at the port will be exposed, and the surface of the rest of the conductive bar 102 is protected by the insulating sleeve) In this way, when the current passes through the conductive bar 102, it can prevent the current from causing damage to the first sponge block 17 and the second sponge block 18, and by arranging the first sponge block 17 and the second sponge block 18 on the front plate-like structure of the positioning plate 9, the non-conductive material of the front plate-like structure of the positioning plate 9 can be used to protect the first sponge block 17 and the second sponge block 18, avoiding the current from passing through the conductive material of the rear plate-like structure of the positioning plate 9. The plate structure causes damage to the first sponge block 17 and the second sponge block 18; when the connecting plate 7 and the positioning plate 9 move backward and reset, the connecting plate 7 and the positioning plate 9 will drive the fixing plate 16, the first sponge block 17 and the second sponge block 18 to move backward and reset, so that the first sponge block 17 and the second sponge block 18 are separated from the insulating sleeve and the surface of the conductive bar 102 in turn.

[0037] See also Fig.10 As shown, it also includes a limiting mechanism, which includes a third electric slide rail 19, a first limiting frame 20, a second limiting frame 21 and a second universal wheel 22; the third electric slide rail 19 is installed on the lower front part of the frame 1; the first limiting frame 20 is connected to the slider of the third electric slide rail 19; the second limiting frame 21 is installed on the right side of the lower front part of the frame 1; the second universal wheel 22 is rotatably installed at the bottom of the first limiting frame 20 and the second limiting frame 21.

[0038] See also Fig.10and Fig.11 As shown, a resistance increasing mechanism is also included, which includes a cylinder 23 and a friction plate 24; the cylinder 23 is installed in the middle of the lower side of the frame 1; and the friction plate 24 is connected to the telescopic rod of the cylinder 23.

[0039] When the frame 1 is pushed to move, the frame 1 will drive the third electric slide rail 19, the first limit frame 20, and the second limit frame 21 to move synchronously, and make the second universal wheel 22 roll on the ground, so as to drive the insulation test device to move to the specified position, so that the frame 1 is aligned with the stacked aluminum alloy bus duct (such as Figure 4 As shown), the second limiting frame 21 contacts the lower right side of the stacked aluminum alloy bus duct, and then the first limiting frame 20 is driven to move rightward by the third electric slide rail 19, so that the first limiting frame 20 contacts the lower left side of the stacked aluminum alloy bus duct, thereby limiting the position of the frame 1 by contacting the stacked aluminum alloy bus duct with the first limiting frame 20 and the second limiting frame 21, so that the frame 1 cannot move left and right, thereby limiting the frame 1, and then driving the friction plate 24 to move downward by the cylinder 23 until the friction plate 24 contacts the ground, In this way, the friction plate 24 is used to increase the resistance to the movement of the frame 1, thereby preventing the frame 1 from moving forwards and backwards, and further stabilizing the frame 1 to prevent the frame 1 from moving arbitrarily and affecting the subsequent insulation test of the aluminum alloy bus duct; when the insulation test of all the stacked aluminum alloy bus ducts has been completed, the friction plate 24 is driven by the cylinder 23 to move upward and reset, so that the friction plate 24 is separated from the ground, and then the first limit frame 20 is driven by the third electric slide rail 19 to move left and reset, so that the first limit frame 20 is separated from the lower left side of the stacked aluminum alloy bus duct.
