Description

[0002] With the improvement of human living standards and the widespread application of electricity and electrical equipment, many places have strict requirements on power supply continuity and do not allow long-term power outages. Most of them use automatic transfer switches to ensure continuous power supply. Automatic transfer switches automatically switch the load power supply circuit from the abnormal power supply to the normal second power supply (backup power supply), which is of great significance to the continuity and reliability of power supply.

[0003] Existing automatic transfer switches, such as a dual power automatic transfer switch proposed in patent application number "CN202223205530.9", have good heat dissipation performance and high safety through structures such as a dual power switch body, a heat conduction plate, and a mounting frame.

[0004] In the prior art, for example, a dual power automatic transfer switch proposed in patent application number "CN202223205530.9" has a shell of an integrated structure.

When the user requires a three-pole switch, the neutral line position will be left vacant, the volume is large, and the cabinet installation space is wasted, and the cost is difficult to reduce. Therefore, an assembled automatic transfer switch is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] An assembled automatic transfer switch includes a control module 1, wherein a plurality of switch modules 2 are fixedly connected to one side of the control module 1, a side plate 3 is fixedly connected to the ends of the plurality of switch modules 2, the plurality of switch modules 2 are mutually clamped, an isolation component is plugged between the plurality of switch modules 2, a connection component is commonly plugged between the plurality of switch modules 2, protrusions 8 are fixedly connected to both sides of the switch modules 2, recesses 7 are provided on both sides of the switch modules 2, and the recesses 7 and protrusions 8 located on different sides of the switch modules 2 are mutually clamped and matched.

[0025] like Figure 1-Figure 5 As shown, by clamping multiple groups of switch modules 2 between the control module 1 and the side plate 3 and connecting them in series through the connecting components, the execution switch module 2 of each pole is modularized, the poles are spliced ​​like building blocks, the positions correspond, and the two incoming lines, the load-side outgoing line, as well as the driving shaft, connecting rod, moving contact system, arc extinguishing chamber, etc. are integrated in an independent cavity, which is beneficial to the pole separation and prevents the formation of phase-to-phase arcs or phase-to-phase short circuits after arcs and environmental pollution. Adjacent switch modules 2 are spliced ​​by protrusions 8 and recesses 7 to achieve the inter-pole housing without misalignment and movement risks, while ensuring the consistency and synchronization of contacts, which not only reduces the development and manufacturing costs and facilitates production and assembly, but also solves the problem of easy conversion between three-pole and four-pole.

[0026] The plurality of switch modules 2 are located between the control module 1 and the side panel 3 . The switch modules 2 away from the side panel 3 are fixed to the side wall of the control module 1 . The upper ends of the control module 1 and the side panel 3 are rotatably connected with handles 4 .

[0027] like Figure 1-Figure 5 As shown, the switch module 2 in contact with the control module 1 is fixed to the control module 1, and the rest are spliced. The handle 4 is convenient for moving the switch.

[0028] The connecting assembly includes a connecting rod 6, and the side walls of multiple groups of switch modules 2 are penetrated with insertion holes 5. One end of the connecting rod 6 is fixed to the side wall of the control module 1, and the middle part of the connecting rod 6 passes through multiple groups of insertion holes 5. The end of the connecting rod 6 away from the control module 1 passes through the side plate 3, and the end of the connecting rod 6 is threadedly connected with a fixing block 15.

[0029] like Figure 1-Figure 5 As shown, the connecting rod 6 connects multiple groups of isolating switches in series to increase the connection stability between the multiple groups of switch modules 2 and prevent them from falling off. One end of the connecting rod 6 is fixed to the control module 1, and the other end fixes the side plate 3 to the end of the switch module 2 through the fixing block 15, thereby fitting and fixing the multiple groups of switch modules 2.

[0030] The insertion openings 5 ​​and the connecting rods 6 are provided in multiple groups, and the multiple groups of connecting rods 6 are respectively plugged and matched with the multiple groups of insertion openings 5 ​​. The fixing block 15 is located at a side of the side plate 3 away from the control module 1 .

[0031] like Figure 1-Figure 5 As shown, multiple groups of connecting rods 6 can better limit the connection stability between multiple groups of switch modules 2.

[0033] like Figure 1-Figure 5 As shown, when two adjacent groups of switch modules 2 are spliced ​​together, the fixing strips 9 on the two groups of switch modules 2 will fit together to form a space that can accommodate the insertion strip 10. Then, the partition 11 can be inserted between the two groups of switch modules 2 through the insertion strip 10 to isolate the adjacent switch modules 2 and prevent arcing.

[0034] The upper ends of the plurality of switch modules 2 are all fixedly connected with heat dissipation openings 13 , and mesh plates 14 are clamped inside the heat dissipation openings 13 .

[0035] like Figure 1 As shown, the heat dissipation opening 13 increases the heat dissipation performance of the switch module 2 , and the mesh plate 14 prevents dust from entering the heat dissipation opening 13 .

[0036] The working principle of an assembled automatic transfer switch provided by the utility model is as follows:

[0037] By clamping multiple groups of switch modules 2 between the control module 1 and the side plate 3 and connecting them in series through the connecting components, the execution switch module 2 of each pole is modularized, and the poles are spliced ​​like building blocks with corresponding positions, so that the inter-pole housing will not be misaligned or have the risk of movement, while ensuring that the contacts are consistent and synchronized, which not only reduces the development and manufacturing costs and facilitates production and assembly, but also solves the problem of easy conversion between three-pole and four-pole.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
