Composite apparatus has a compact structure, small appearance and installation size, is easy to use, and the performance of each appliance can be better coordinated. Composite apparatus can be divided into low-voltage composite apparatus and high-voltage composite apparatus according to voltage.

[0003] However, the main conductive rod and busbar conductor of the three-way module of the high-voltage combined electrical appliance are fastened with only one screw, which means that the branch conductive rod may be oriented in any direction. In order to ensure the correct position of the branch conductive rod, the three-way module needs to be aligned during assembly. The alignment assembly method currently used for the three-way module is: First, install the three-way housing to the insulator, and pre-install the main conductive rod, branch conductor point and commutation conductor respectively; secondly, install the positioning plate on the three-way housing, and use the cooperation of the three-way housing and the positioning plate to adjust the main conductive rod to the correct position; then, draw marking lines on the surface of the main conductive rod and the bus conductor to determine the position of the main conductive rod and the bus conductor; then, remove the branch conductive rod and the three-way housing; then, tighten the connecting screws of the main conductive rod and the bus conductor according to the alignment marking line; finally, install the three-way housing and the branch conductive rod again. This alignment assembly method requires repeated disassembly and assembly to complete the assembly, and the assembly efficiency is low.

[0004] In view of the existence of the above problems, it is necessary to study an alignment tool and an alignment assembly method for a three-way module of a high-voltage combined electrical appliance, which can ensure that the three-way module can be assembled quickly and accurately. Summary of the invention

[0010] The positioning soft sleeve is nested with the positioning hole.

[0011] The positioning bracket includes a positioning support seat and a positioning base, the positioning support seat is fixed to the positioning base, and the positioning base is matched with the positioning pin; The three-phase positioning plate is connected to the positioning support seat.

[0014] In the step three, after adjusting the three bus-connecting conductors and the three main conductive rods until the three branch conductive rods can be connected to the three main conductive rods respectively, the three branch conductive rods are connected to the three main conductive rods respectively.

DETAILED DESCRIPTION

[0028] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0029] like Figures 1 to 3 As shown, the present invention discloses an alignment tool 1 for a three-way module 2 of a high-voltage combined electrical appliance, and the alignment tool 1 is used for aligning the three-way module 2 of the high-voltage combined electrical appliance when it is assembled, so as to ensure accurate assembly of the three-way module 2 and improve assembly efficiency of the three-way module 2. Specifically, the alignment tool 1 includes a positioning bracket 11 and a three-phase positioning plate 12 installed on the positioning bracket 11, the three-phase positioning plate 12 is provided with at least one positioning unit 121, each positioning unit 121 includes three positioning holes 1211 arranged at intervals and distributed in a central rotational symmetric manner, and the positioning bracket 11 is provided with at least two positioning pins 113 for plugging with the insulator 21 of the three-way module 2.

[0030] Cooperate Figures 4 to 10 As shown, the present invention also discloses a method for aligning and assembling a three-way module 2 of a high-voltage combined electrical appliance. The method for aligning and assembling adopts the alignment tool 1 as described above. The method for aligning and assembling specifically comprises: Step 1: pre-tighten the three bus-coupler conductors 22 on the insulator 21 by means of fixing screws 201, and pre-tighten the three main conductive rods 23 on the three bus-coupler conductors 22 respectively by means of connecting screws 202; Step 2: insert each positioning pin 113 of the positioning bracket 11 of the alignment tool 1 onto the insulator 21; Step 3: The three branch conductive rods 24 are respectively passed through the three positioning holes 1211 of a positioning unit 121 of the three-phase positioning plate 12 of the alignment tool 1, and the three bus conductors 22 and the three main conductive rods 23 are adjusted until the three branch conductive rods 24 can be connected to the three main conductive rods 23 respectively. At this time, the positions of the three bus conductors 22 and the three main conductive rods 23 are the correct assembly positions, thereby ensuring the accurate assembly of the three branch conductive rods 24; Step 4: First, tighten each fixing screw 201 to fix the three bus-connecting conductors 22 on the insulator 21, and then tighten each connecting screw 202 to respectively lock the three main conductive rods 23 and the three bus-connecting conductors 22; Step 5: Remove the alignment tool 1 and the three branch conductive rods 24; Step 6: First, lock the three-way housing 25 and the insulator 21, and then connect the three branch conductive rods 24 and the three main conductive rods 23 respectively.

[0031] From the above, it can be seen that when the alignment tool 1 of the present invention is used to align and assemble the three-way shell 25, the accurate assembly of the three branch conductive rods 24 can be guaranteed, thereby ensuring the accuracy of the assembly of the three-way shell 25; moreover, when the three-way module 2 is aligned and assembled, the three-way shell 25 only needs to be installed once, and there is no need to repeatedly disassemble and assemble the three-way shell 25, thereby making the assembly of the three-way shell 25 faster.

[0032] In an embodiment of the present invention, the three-phase positioning plate 12 may be provided with two positioning units 121, and the positioning holes 1211 of the two positioning units 121 are arranged alternately, and the two positioning units 121 are also distributed in a central rotational symmetric manner; the two positioning units 121 can adapt to different phase sequence requirements, and different phase sequences will cause different positions of the three branch conductive rods 24. In addition, a through hole 123 may be provided in the center of the three-phase positioning plate 12, and the positioning holes 1211 of each positioning unit 121 are distributed in a central rotational symmetric manner about the through hole 123, and the through hole 123 can reduce the material used in the three-phase positioning plate 12 and reduce the cost.

[0034] In an embodiment of the present invention, the positioning bracket 11 includes a positioning support seat 111 and a positioning base 112. The positioning support seat 111 is fixed to the positioning base 112. The positioning support seat 111 can be connected to the positioning base 112 through a bolt assembly. The positioning base 112 is equipped with the positioning pin 113. The positioning pin 113 can be plug-fitted or screw-fitted with the positioning base 112. The positioning base 112 has a "U"-shaped structure to avoid the main conductive rod 23 and the busbar conductor 22; the three-phase positioning plate 12 is connected to the positioning support seat 111, and the three-phase positioning plate 12 can be connected to the positioning support seat 111 through a bolt assembly.

[0035] In the embodiment of the present invention, in step 3, after adjusting the three bus-coupler conductors 22 and the three main conductive rods 23 to allow the three branch conductive rods 24 to be respectively connected to the three main conductive rods 23, the three branch conductive rods 24 are respectively connected to the three main conductive rods 23, so that the bus-coupler conductors 22 and the main conductive rods 23 are restricted by the branch conductive rods 24 to prevent the bus-coupler conductors 22 and the main conductive rods 23 from shifting. The branch conductive rods 24 and the main conductive rods 23 can be locked by the locking screws 203.

[0036] In the embodiment of the present invention, in step six, the three-way housing 25 and the insulator 21 are locked by installing screws 204 to ensure that the three-way housing 25 is firmly installed.
