[0035] like Figures 1 to 11 The utility model provides a power switch module assembly structure. The power switch module assembly structure includes a mounting folding plate 1, a switch mounting plate 2, a first copper bar bracket 3 and a second copper bar bracket 4. Figure 2 , Figure 3 and Figure 4 As shown, the installation folding plate 1 includes a first folding plate 5, a second folding plate 6 and a third folding plate 7.

The open installation plate 2 and one end of the second folding plate 6 are fixedly connected by an L-shaped bracket 8, and the connected open installation plate 2 is parallel to the first folding plate 5. The second folding plate 6 is fixedly connected with an N-phase copper busbar 9.

[0036] In some embodiments, Figure 2 The L-shaped bracket 8 includes a fourth folding plate 13 and a fifth folding plate 14 connected perpendicularly to each other. A plurality of first thread ties 15 are provided at equal intervals in the horizontal direction on the fourth folding plate 13.

Each line bundle can be arranged and integrated through the perforated lines, so as to facilitate the arrangement of the overall lines of the power switch module and make them neatly distributed.

[0038] like Figure 2 , Figure 5 and Figure 6 The rear end of the transfer copper bar 10 is fixedly mounted on the first folding plate 5, and the front end of the transfer copper bar 10 is fixedly connected to the third folding plate 7. The first copper bar bracket 3 is fixedly mounted on the first folding plate 5 and corresponds to the rear end of the transfer copper bar 10. The second copper bar bracket 4 is fixedly mounted on the third folding plate 7 and corresponds to the front end of the transfer copper bar 10.

[0039] The input copper bar 11 is fixedly mounted on the second copper bar bracket 4. The AC incoming line circuit breaker is mounted on the third folding plate 7, and the input copper bar 11 is connected to the front end of the transfer copper bar 10 through the AC incoming line circuit breaker. The output copper bar 12 is fixed on the first copper bar bracket 3. The AC contactor is fixedly mounted on the first folding plate 5, and the output copper bar 12 is connected to the rear end of the transfer copper bar 10 through the AC contactor.

The transfer copper bar 10 includes an A-phase transfer copper bar 10, a B-phase transfer copper bar 10, and a C-phase transfer copper bar 10.

[0041] In detail, the mutual inductor, AC metering meter, lightning arrester, lightning arrester switch, and miniature leakage circuit breaker on the existing power switch module are all installed in the power switch module assembly structure provided in this embodiment. The specific assembly connection method is as follows: the mutual inductor and AC metering meter provided on the A-phase input copper bar 11, the B-phase input copper bar 11, and the C-phase input copper bar 11 are connected. Power line lead-out holes are respectively opened on the A-phase input copper bar 11, the B-phase input copper bar 11, and the C-phase input copper bar 11, which are used to connect to the AC metering meter through the power line. Use yellow, green, and red power lines to connect the A-phase input copper bar 11, the B-phase input copper bar 11, and the C-phase input copper bar 11 to the lightning arrester switch respectively, and then connect the lightning arrester switch to the lightning arrester, and then use the yellow-green ground wire to lead to the grounding copper bar, so that the power switch module has a lightning protection function to protect the equipment from being damaged by lightning current.

[0042] Any one of the A-phase input copper bar 11, the B-phase input copper bar 11, and the C-phase input copper bar 11 and the N-phase copper bar 9 are respectively led out to the power line L line and the N line to be connected to the miniature leakage circuit breaker, and then connected to the switching power supply or other loads by the miniature leakage circuit breaker, and used as a single-phase 220V AC power supply; in addition, the three-phase AC power input flows through the input copper bar 11, and after being controlled and connected by the AC incoming line circuit breaker, it flows through the A-phase transfer copper bar 10, the B-phase transfer copper bar 10, and the C-phase transfer copper bar 10, and flows to the AC contactor. After the AC contactor is powered on and attracted, the three-phase AC current flows to the A-phase output copper bar 12, the B-phase output copper bar 12, and the C-phase output copper bar 12. A plurality of power output holes are opened on the output copper bar 12, and the three-phase output copper bar 12 is then distributed to multiple loads (for example, the output is distributed to the AC-to-DC power supply module).

[0043] In some embodiments, in combination Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the first copper bar bracket 3 is designed as a stepped fixing block. The A-phase output copper bar 12, the B-phase output copper bar 12 and the C-phase output copper bar 12 are respectively fixedly installed on the steps of the stepped fixing block from high to low. This structure can make the overall occupied space relatively small, facilitate the copper bar wiring, and meet the safety distance between the three-phase copper bars.

[0044] The second copper busbar bracket 4 is designed as a convex-shaped fixing block; the A-phase input copper busbar 11, the B-phase input copper busbar 11, and the C-phase input copper busbar 11 are respectively fixed on the steps of the convex-shaped fixing block in sequence from left to right. This structure can make the overall occupied space relatively small, facilitate the wiring of copper busbars, and meet the safety distance between the three-phase copper busbars. The input copper busbar 11, the output copper busbar 12, and the转接 copper busbar 10 have a simple structure. Through the cooperation of the first copper busbar bracket 3 and the second copper busbar bracket 4, the copper busbar structure can be simplified, effectively avoiding the combination of special-shaped copper busbars and making the production complicated.

[0045] In some embodiments, such as Figure 4 , the air switch mounting plate 2 and the L-shaped bracket 8 are directly hinged through the hinge 18, which is convenient for maintenance personnel to open and close, improving the maintenance efficiency. The air switch mounting plate 2 further includes an L-shaped limiting bracket 19. A long groove 20 is provided on the L-shaped limiting bracket 19. The hand-rotating screw 21 is screwed and fixed on the inner wall of the air switch mounting plate 2 through the long groove 20. When the maintenance personnel rotate and open the air switch mounting plate 2 for maintenance, the hand-rotating screw 21 is rotated, so that the L-shaped limiting bracket 19 can move up and down relative to the hand-rotating screw 21. Move until the bottom of the L-shaped limiting bracket 19 contacts the L-shaped bracket 8, and tighten the hand-rotating screw 21. The L-shaped limiting bracket 19 will limit the air switch mounting plate 2 to prevent it from rotating and closing due to factors such as misoperation, facilitating the maintenance operations of maintenance personnel.

[0046] In some embodiments, such as Figure 1 , Figure 2 and Figure 7 As shown, a plurality of wire grooves 22 are provided around the outer wall of the air switch mounting plate 2. The plurality of wire grooves 22 are arranged to form a "day" shape, and electronic components such as a metering electric meter, a miniature leakage circuit breaker, a lightning arrester switch, and a lightning arrester in the power switch module are installed in the space surrounded by the wire grooves 22. The wire harness passing through the first wire buckling buckle 15 and the second wire buckling buckle 16 is distributed along the wire grooves 22, facilitating the regularization of the wire harness.

[0047] Among them, a lower support frame 24 is installed between the first folding plate 5 and the air switch mounting plate 2, so that the air switch mounting plate 2 is parallel to the first folding plate 5; there are two parallel side support plates 23 between the second side and the third folding plate 7, and the two side support plates 23 are fixedly connected through a support column 25. The lower support frame 24 and the side support plates 23 can both improve the overall support strength of the assembly structure of the power switch module. The air switch mounting plate 2 is provided with an upper air switch guide rail 26 and a lower air switch guide rail 27 that are parallel up and down, facilitating the convenient installation of electronic components such as a metering electric meter, a miniature leakage circuit breaker, a lightning arrester switch, and a lightning arrester in the power switch module. The first folding plate 5 is further provided with a folded side support frame 28, and the side support frame 28 can assist the lower support frame 24 to jointly support the air switch mounting plate 2.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
