DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely intended to explain this application and are not intended to limit this application. Furthermore, the embodiments and features of the embodiments in this application may be combined with each other unless there is a conflict.

[0027] Figure 1 FIG. 1 shows a schematic diagram of the three-dimensional structure of an output bus 100 of a dual-way switch according to an embodiment of the present application. Figure 2FIG shows a left side view of the output busbar 100. Figure 1 As shown, the dual-way switch includes a first switch 1 and a second switch 2 arranged side by side, and the output bus 100 is mainly composed of two first-phase lead-out bars 110, two second-phase lead-out bars 120, two third-phase lead-out bars 130, a first-phase parallel strapping bar 140 connecting the two first-phase lead-out bars 110, a second-phase parallel strapping bar 150 connecting the two second-phase lead-out bars 120, a third-phase parallel strapping bar 160 connecting the two third-phase lead-out bars 130, a first-phase interface bar 170 led from the first-phase parallel strapping bar 140, a second-phase interface bar 180 led from the second-phase parallel strapping bar 150, and a third-phase interface bar 190 led from the third-phase parallel strapping bar 160.

[0028] See Figure 1 Combine Figure 2 As shown, the operating handle side of the first switch 1 and the second switch 2 is the front side, and the opposite direction is the rear side. The first switch 1 and the second switch 2 are arranged side by side on the left and right, and the first phase lead-out bar 110, the second phase lead-out bar 120 and the third phase lead-out bar 130 are respectively led out from the bottom, that is, the A, B, and C three-phase outputs. The third-phase lead-out row 130 extends vertically downward, and the first-phase lead-out row 110 bends forward relative to the third-phase lead-out row 130, and is composed of a first-phase first lead-out section 111 extending vertically downward, a first-phase second lead-out section 112 extending horizontally and bending forward from the lower end of the first-phase first lead-out section 111, and a first-phase third lead-out section 113 extending vertically and bending downward from the front end of the first-phase second lead-out section 112. The second-phase lead-out row 120 bends backward relative to the third-phase lead-out row 130, and is composed of a second-phase first lead-out section 121 extending vertically downward, and a second-phase second lead-out section 122 extending horizontally and bending backward from the lower end of the second-phase first lead-out section 121. Figure 1 Combine Figure 2As shown, a first-phase parallel bonding bar 140 is vertically arranged, with its ends fastened to the front sides of the first-phase third lead sections 113 of the two first-phase lead-out bars 110 of the first and second switches 1 and 2, for example, by screws, to connect the two first-phase lead-out bars 110 after they are bent forward. A second-phase parallel bonding bar 150 is horizontally arranged, with its ends fastened to the bottom sides of the second-phase second lead sections 122 of the two second-phase output bars 120 of the first and second switches 1 and 2, for example, by screws, to connect the two second-phase lead-out bars 120 after they are bent backward. A third-phase parallel bonding bar 160 is vertically arranged, with its ends fastened to the rear lower ends of the two third-phase lead-out bars 130 of the first and second switches 1 and 2, for example, by screws, to connect the two third-phase lead-out bars 130. In a specific implementation, the first-phase parallel bonding bar 140, the second-phase parallel bonding bar 150, and the third-phase parallel bonding bar 160 can be conductive bars of the same structure to save processing costs. See further Figure 1 Combine Figure 2 As shown, the first phase interface row 170 is composed of a first phase first interface section 171 extending vertically downward, a first phase second interface section 172 extending laterally from the lower end of the first phase first interface section 171 and bending backward, and a first phase third interface section 173 extending vertically downward from the rear end of the first phase second interface section 172. The upper end of the first phase first interface section 171 is fixed to the left side of the rear side of the first phase parallel lap row 140 by, for example, fixing screws, so as to lead the first phase interface row 170 downward from the first phase parallel lap row 140. Second-phase interface row 180 comprises a transversely extending second-phase first interface section 181, a second-phase second interface section 182 that bends downward and extends vertically from the rear end of second-phase first interface section 181, a second-phase third interface section 183 that bends forward and extends transversely from the lower end of second-phase second interface section 182, and a second-phase fourth interface section 184 that bends downward and extends vertically from the front end of second-phase third interface section 183. Second-phase first interface section 181 is secured to the left side of the bottom of second-phase parallel lap row 150, for example, by means of fixing screws, so as to guide second-phase interface row 180 downward from second-phase parallel lap row 150. Third-phase interface row 190 extends vertically downward, with its upper end secured to the middle front side of third-phase parallel lap row 160 by means of fixing screws, for example, and its lower end guided vertically downward. In this way, the first-phase third interface section 173 of the first-phase interface row 170, the second-phase fourth interface section 184 of the second-phase interface row 180, and the lower end of the third-phase interface row 190 are distributed in a herringbone shape, and screw holes can be reserved for further connection of a three-phase bus or cable (not shown in the figure).

[0029] See also Figure 1 Combine Figure 2As shown, the first phase first interface section 171 of the first phase interface bank 170, the second phase second interface section 182 of the second phase interface bank 180, and the third phase interface bank 190 are respectively fixedly mounted with current transformers 3 via fixing components 4. The function of the current transformers 3 is to collect the current signal flowing through the conductor for measurement and monitoring. Taking the third phase interface bank 190 as an example, see Figure 3 As shown, the fixing assembly 4 includes a fixing part 41 formed of sheet metal to frame the current transformer 3. The open side of the fixing part 41 extends up and down to form a fixing edge 42. The fixing edge 42 is locked with the corresponding third-phase interface row 190 by fixing screws 43 after the plastic gasket 44 is laid. The plastic gasket 44 has a certain elasticity, which can reduce the stress of the sheet metal fixing part 41 on the current transformer 3 when it is locked by the fixing screw 43. The fixing structure occupies less space on the conductive bar, thereby shortening the length of the conductive bar. According to different embodiments of the present application, the fixing assembly 4 for fixing the current transformer 3 can also be used Figure 4 Also taking the third phase interface row 190 as an example, see Figure 4 As shown, the fixing assembly 4 includes a fixing block 401 that is injection molded to frame the current transformer 3. The upper and lower ends of the opening side of the fixing block 401 respectively form fixing edges 402 that are locked with the corresponding third phase interface row 190 through fixing screws 43.

[0030] Figure 5 FIG. 2 shows a schematic diagram of the three-dimensional structure of an output bus 200 of a dual-way switch according to another embodiment of the present application. Figure 6 FIG shows a left side view of the output bus 200. Figure 5 and Figure 6 As shown, the output bus 200 has the same Figure 1 and Figure 2 The output busbar 100 in the illustrated embodiment has a substantially identical structural design and is primarily composed of two first-phase lead-out bars 210, two second-phase lead-out bars 220, two third-phase lead-out bars 230, respectively, which are led out from the bottoms of the first switch 1 and the second switch 2 arranged side by side, a first-phase parallel connecting bar 240 connecting the two first-phase lead-out bars 210, a second-phase parallel connecting bar 250 connecting the two second-phase lead-out bars 220, a third-phase parallel connecting bar 260 connecting the two third-phase lead-out bars 230, a first-phase interface bar 270 led out from the first-phase parallel connecting bar 240, a second-phase interface bar 280 led out from the second-phase parallel connecting bar 250, and a third-phase interface bar 290 led out from the third-phase parallel connecting bar 260. Compared to the aforementioned Figure 1 and Figure 2 The output busbar 100 in the embodiment shown, Figure 3 and Figure 4The output busbar 200 shown is different in that the first phase parallel connection bar 240 and the two first phase lead bars 210 are integrally formed, the second phase parallel connection bar 250 and the two second phase lead bars 220 are integrally formed, and the third phase parallel connection bar 260 and the two third phase lead bars 230 are integrally formed. Figure 5 and Figure 6 As shown, the two first-phase lead-out rows 210 each have a first-phase first lead-out section 211 extending vertically downward, a first-phase second lead-out section 212 extending laterally by bending forward from the lower end of the first-phase first lead-out section 211, and a first-phase third lead-out section 213 extending vertically by bending downward from the front end of the first-phase second lead-out section 212. The first-phase parallel lap row 240 is integrally connected between the two first-phase third lead-out sections 213. Similarly, the two second-phase lead-out rows 220 each have a second-phase first lead-out section 221 extending vertically downward and a second-phase second lead-out section 222 extending laterally by bending backward from the lower end of the second-phase first lead-out section 221. The second-phase parallel lap row 250 is integrally connected between the two second-phase second lead-out sections 222, and the third-phase parallel lap row 260 is integrally connected between the lower ends of the two third-phase lead-out rows 230. The first-phase interface row 270, the second-phase interface row 280, and the third-phase interface row 290 have the same characteristics as those described above. Figure 1 and Figure 2 The first phase interface row 170, the second phase interface row 180 and the third phase interface row 190 of the output busbar 100 of the illustrated embodiment have the same structure, and are respectively led downward from the first phase parallel lap row 240, the second phase parallel lap row 250 and the third phase parallel lap row 260 in the rear, middle and front directions, and will not be described in detail here. Similarly, the first phase first interface section 271 of the first phase interface row 270, the second phase second interface section 282 of the second phase interface row 280 and the third phase interface row 290 are respectively fixedly mounted with a current transformer 3 via a fixing assembly 4. The specific structural implementation of the fixed installation of the current transformer 3 by the fixing assembly 4 can be referred to in the aforementioned combined method. Figure 3 and Figure 4 A description of an embodiment is given.

[0031] See also Figure 7 As shown, in actual applications, most AC switch cabinets need to cover the switches and conductors with a protective panel 5, leaving only the operating handle 6 exposed to protect the safety of maintenance personnel and keep the operation interface simple and beautiful. When the output bus of the dual-way switch according to the above embodiment of the present application is used in an AC switch cabinet, take the output bus 100 as an example, see Figure 7As shown, this output busbar structure not only facilitates the installation of the current transformer, but also ensures the electrical safety distance between the conductive bars of each phase. It can save the length of the conductive bar to the greatest extent, while fully utilizing the space under the switch. The front face of the current transformer does not exceed the front face of the first switch 1 and the second switch 2, which facilitates the installation of the protective cover 6. After the two-way switch passes through the output busbar 100, a three-phase terminal bar 7 can be arranged below the three-phase interface bar, or the aforementioned three-phase interface bar can be extended to serve as the terminal bar 7. Multiple branch switches 8 can be arranged in front of the terminal bar 7, connected to the three-phase terminal bar 7 via cables or conductive bars. The output end is led out of the cabinet via cables or conductive bars plus cables to distribute power to various loads and provide circuit breaker protection.

[0032] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
