Currently, assembling the outgoing conductor of a three-phase circuit breaker with the moving conductor of a three-position switch requires repeated manual disassembly and adjustment to ensure that the coaxiality of the outgoing conductor and the mounting hole of the current transformer, as well as the parallelism and distance between the end face of the outgoing conductor and the transformer flange of the current transformer, meet the assembly requirements, which is extremely time-consuming and labor-intensive.

[0053] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0054] like Figures 1 to 17As shown, the present invention discloses an alignment fixture, which includes an alignment device A; the alignment device A includes a positioning plate 1, a positioning sleeve 2, a positioning pin 3, a positioning rod 4, and a positioning head 5; the positioning plate 1 has a positioning through hole 11 at its center, and the positioning plate 11 also has a plurality of mounting through holes 12 that are rotationally symmetrical about the positioning through hole 11; the positioning sleeve 2 passes through the positioning through hole 11 of the positioning plate 1 and is in transition fit with the positioning through hole 11, the outer wall of the positioning sleeve 2 has a locking part 21 that abuts against the end face of the positioning plate 11, the center of the positioning sleeve 2 forms a through positioning sleeve hole 22, the positioning sleeve hole 22 is coaxially arranged with the positioning through hole 11, the positioning sleeve hole 21 is used to fit the positioning rod 4 and is in transition fit with the positioning rod 4; the number of positioning pins 3 is at least two, and each positioning pin 3 is inserted into the mounting through hole 12 of the positioning plate 1; the positioning head 5 is used to fit the end of the positioning sleeve 2, the positioning head 2 has a positioning plane 51 that abuts against the end of the positioning sleeve 2, and the positioning plane 51 is parallel to the positioning plate 1. The positioning plate 1, positioning sleeve 2, positioning pin 3 and positioning rod 4 of the alignment device A are used to align and install the lower conductor C1 of the outgoing conductor C. The positioning plate 1, positioning sleeve 2, positioning pin 3 and positioning head of the alignment device A are used to align and install the upper conductor C1 of the outgoing conductor C. The positioning plate 1, positioning sleeve 2 and positioning pin 3 of the alignment device A are used to align and install the current transformer D.

[0055] Cooperate Figures 7 to 17 As shown, this invention also discloses a method for aligning the outgoing conductors of a three-phase circuit breaker. This method employs the alignment fixture described above. The method specifically includes the following sequential steps:

[0056] Step 1: Pre-assemble the three circuit breaker bodies E of the three-phase circuit breaker; the pre-assembly process of the circuit breaker bodies E is existing technology and will not be described in detail here.

[0057] Step 2: Install the lower conductor C1 of the outgoing conductor C onto the circuit breaker body E, including: First, connecting the positioning rod 4 of the alignment device A to the outgoing conductor connection part E1 inside the circuit breaker body E using connecting screws; Second, aligning the positioning plate 1 of the alignment device A with the circuit breaker flange E2 of the circuit breaker body E, and positioning the positioning pin 3 of the alignment device A through the mounting hole 12 of the positioning plate 1 and the flange hole of the circuit breaker flange E2 to position the positioning plate 1 and the circuit breaker flange E2; Then, passing the positioning sleeve 2 of the alignment device A through the positioning hole 12 of the positioning plate 1, such that the locking part 21 of the positioning sleeve 2... The positioning plate 1 is engaged with the end face of the positioning rod 4, and the position of the positioning rod 4 is adjusted so that the positioning rod 4 is inserted into the positioning sleeve hole 22 of the positioning sleeve 2. At this time, the outgoing conductor connection part E1 is coaxially set with the circuit breaker flange E2 so that the outgoing conductor connection part E1 is aligned. Next, the positioning plate 1, positioning rod 4, positioning sleeve 2 and positioning pin 3 of the alignment device A are removed from the circuit breaker body E. Finally, the lower end conductor C1 of the outgoing conductor C is pre-connected to the outgoing conductor connection part E1 inside the circuit breaker body E through the connecting screw. In this way, the lower end conductor C1 is coaxially set with the circuit breaker flange E2 so that the lower end conductor C1 is initially aligned.

[0058] Step 3: Install the current transformer D onto the circuit breaker body E, including: First, pre-connect the current transformer D to the circuit breaker flange E2 of the circuit breaker body E using connecting bolts; Second, align the positioning plate 1 of the alignment device A with the transformer flange D1 of the current transformer D, and pass the positioning pin 3 of the alignment device A through the mounting hole 12 of the positioning plate 1 and the flange hole of the transformer flange D1 to position and engage the positioning plate 1 with the transformer flange D1; Then, pass the positioning sleeve 2 of the alignment device A through the positioning hole of the positioning plate 1. 12. The positioning sleeve 2's locking part 21 is engaged with the end face of the positioning plate 1. At the same time, the position of the current transformer D is adjusted so that the lower conductor C1 of the outgoing conductor C is inserted into the positioning sleeve hole 22 of the positioning sleeve 2. At this time, the current transformer D and the lower conductor C1 of the outgoing conductor C are coaxially arranged. Finally, the connecting bolts are tightened to lock the current transformer D to the circuit breaker flange E2 of the circuit breaker body E, and the connecting screws are tightened to lock the lower conductor C1 of the outgoing conductor C to the outgoing conductor connection part E1 inside the circuit breaker body E.

[0059] Step 4: Connect the upper conductor C2 of the outgoing conductor C to the lower conductor C1 of the outgoing conductor C. This includes: First, replacing the positioning sleeve 2 of the alignment device A, and pre-connecting the upper conductor C2 of the outgoing conductor C to the lower conductor C1 of the outgoing conductor C using mounting screws, ensuring that the upper conductor C2 of the outgoing conductor C passes through the positioning sleeve hole 22 of the positioning sleeve 2 of the alignment device 2. At this point, the upper conductor C2 of the outgoing conductor C is coaxially aligned with the current transformer D. Then, place the positioning head 5 of the alignment device A onto the end of the positioning sleeve 2, and simultaneously adjust the upper conductor C2 of the outgoing conductor C. The position is such that the end face of the upper conductor C2 of the outgoing conductor C is abutted against the positioning plane 51 of the positioning head 5, thereby making the end face of the upper conductor C2 of the outgoing conductor C parallel to the transformer flange D1 of the current transformer D and ensuring that the distance between the end face of the upper conductor C2 of the outgoing conductor C and the transformer flange D1 of the current transformer D meets the assembly requirements; then, tighten the mounting screws to lock the upper conductor C2 of the outgoing conductor C and the lower conductor C1 of the outgoing conductor C; finally, remove the positioning plate 1, positioning sleeve 2, positioning pin 3 and positioning head 5 of the alignment device A from the current transformer D.

[0060] As can be seen from the above, when assembling the outgoing conductor C, current transformer D, and circuit breaker body E, the present invention can quickly achieve the following through the alignment device A: the lower conductor C1 of the outgoing conductor C is coaxially arranged with the current transformer D; the end face of the upper conductor C2 of the outgoing conductor C is parallel to the transformer flange D1 of the current transformer D; and the distance between the end face of the upper conductor C2 of the outgoing conductor C and the transformer flange D1 of the current transformer D meets the assembly requirements. This achieves accurate alignment and installation of the outgoing conductor of the three-phase circuit breaker, facilitating the subsequent accurate assembly of the outgoing conductor with the moving end conductor of the three-position switch, and helping to improve assembly efficiency.

[0061] Cooperate Figure 1 and Figure 3 As shown, in an embodiment of the present invention, the positioning plate 1 is provided with at least one observation port 13 to facilitate access to the interior of the circuit breaker body E and the current transformer D. This observation port 13 also reduces the material usage of the positioning plate 1, thereby reducing the cost of the alignment device A. The positioning sleeve 2 has a clearance opening on its side wall. This clearance opening is used to allow clearance for tools when connecting the upper conductor C2 of the outgoing conductor C to the lower conductor C1 of the outgoing conductor C using mounting screws, thus facilitating the tightening of the mounting screws.

[0062] The material reduction port; the positioning sleeve 2 is used to position the center of the outgoing conductor C. The present invention can select a positioning sleeve 2 of appropriate length according to the length of the outgoing conductor C; in addition, the present invention can select a corresponding positioning head 5 according to the distance between the end face of the upper conductor C2 of the outgoing conductor C and the transformer flange D1 of the current transformer D.

The leveling mounting frame B includes a base frame 6 and at least one leveling mechanism 7 mounted on the base frame 6. The number of leveling mechanisms 7 can be three, for installing the three circuit breaker bodies E (A-phase, B-phase, and C-phase). The leveling mechanism 7 can adjust the circuit breaker flange E2 of the circuit breaker body E to a horizontal position for installation. In step one, after the three circuit breaker bodies E of the three-phase circuit breaker are pre-installed, the three circuit breaker bodies E are respectively installed onto the three leveling mechanisms 7 of the leveling mounting frame B, and the circuit breaker flange E2 of the circuit breaker body E is adjusted to a horizontal position using the adjustment mechanism.

[0064] In an embodiment of the present invention, the leveling mechanism 7 includes at least two leveling components 71. Each leveling component 71 includes a fixed seat 711 connected to the base frame 6 and a leveling seat 712 connected to the fixed seat 711. The installation angle between the leveling seat 712 and the fixed seat 711 is adjustable to level the circuit breaker flange E2 of the circuit breaker body E. The fixed seat 711 is provided with multiple fixing holes 7111, and the leveling seat 712 is provided with multiple adjusting holes 7121. The leveling seat 712 is connected to the fixed seat 711 by at least two connecting bolts 713 passing through the adjusting holes 7121 and the fixing holes 7111. The present invention can control the installation angle between the leveling seat 712 and the fixed seat 711 by selecting different adjusting holes 7121 and fixing holes 7111 to cooperate with the connecting bolts 713. The leveling seat 712 may be provided with a connecting plate 7122 for connecting the circuit breaker body E. The connecting plate 7122 is provided with connecting holes 7123 for connecting the circuit breaker body E by bolts. Furthermore, the leveling mounting bracket B also includes multiple casters 8 connected to the base frame 6, thereby facilitating the movement of the leveling mounting bracket B.
