[0002] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. They can be used to distribute electrical energy and protect power lines and motors. When they have serious overloads, short circuits, undervoltage and other faults, they can automatically cut off the circuit. Its function is equivalent to the combination of a fuse switch and an over-underheating relay.

[0003] When dual power products on the market fail on site, they can only be returned to the factory for repair or replaced, which greatly delays work time. At the same time, repair and replacement will cause a lot of resource waste. Therefore, according to the working characteristics of the existing dual power automatic transfer switch, the utility model divides each phase circuit into an independent module, and the electric operating mechanism is also an independent module. Users can replace each faulty module by themselves, which reduces the time for fault repair and reduces resource waste. Utility Model Content

The positioning columns are provided with positioning blocks corresponding to each ABCN phase independent switch module, and the positioning blocks are circular, and the positioning columns pass through the center of the positioning blocks and are fixed as a whole.

Positioning columns 5 are inserted at the positions of the positioning holes for assembly and positioning, and then assembled with the switch electric operation module 1 by screws 6 to form an integral structure. The positioning columns pass through the corresponding positioning holes of each ABCN phase independent switch module to prevent the switch module from displacement. The screws used for fixing are long-rod screws, specifically two, corresponding to the opposite corner positions of the ABCN phase independent switch module. The positioning columns 5 are provided with positioning blocks 51 corresponding to each ABCN phase independent switch module 2.

The connecting column 4 is sleeved on the supporting column 41 at the position corresponding to the fixed end cover 31. The fixed end cover 31 is provided with a spring sheet 42 to limit the support column 41 to prevent the 4-pole shaft sleeve of the connecting column from swinging at will.

[0028] like Figure 3 As shown: the bottom plate 3 has a slide rail 33, and each ABCN phase independent switch module 2 has a slide groove 22 that engages with the slide rail 33 and is slidably installed. There are two slide rails, which are distributed up and down corresponding to the midline of the ABCN phase independent switch module, and the slide groove is a dovetail groove, which has the dual functions of sliding and limiting.
