Of course, the shape of the tripping piece 41 is not limited to the above shape.

[0070] In the embodiment, as shown in Figures 2-6The electromagnetic mechanism 42 for opening the switch is shown in Figs. 8 and 9. The electromagnetic mechanism 42 for opening the switch is the existing electromagnetic mechanism. The electromagnetic mechanism 42 for opening the switch comprises a coil assembly. The coil assembly is fixed to the side plate 101. The coil assembly comprises a coil frame and a yoke surrounding the coil frame. One end of the coil frame is provided with a static iron core.

[0072] In the embodiment, the dual power switch operating mechanism is used to control the connection and disconnection of the main power supply and the standby power supply. Figures 2-6 In Figs. 8 and 9, the swing arm 3 is used as a boundary. The right side of the swing arm 3 is the main power supply side. The left side of the swing arm 3 is the standby power supply side. The two main electromagnetic drive mechanisms 2, the locking assemblies 7, the connecting rod assemblies 6 and the auxiliary electromagnetic drive mechanisms 5 are symmetrically distributed on the left and right sides of the swing arm 3. The main electromagnetic drive mechanism 2, the locking assembly 7, the connecting rod assembly 6 and the auxiliary electromagnetic drive mechanism 5 on the right side of the swing arm 3 are used in cooperation with the swing arm 3 and the drive mechanism 4 for opening the switch to drive the connection and disconnection of the main power supply. The main electromagnetic drive mechanism 2, the locking assembly 7, the connecting rod assembly 6 and the auxiliary electromagnetic drive mechanism 5 on the left side of the swing arm 3 are used in cooperation with the swing arm 3 and the drive mechanism 4 for opening the switch to drive the connection and disconnection of the standby power supply. The main electromagnetic drive mechanisms 2, the auxiliary electromagnetic drive mechanisms 5, the locking assemblies 7 and the connecting rod assemblies 6 on the main power supply side and the standby power supply side are symmetrically distributed. When the swing arm 3 is rotated to the dual disconnection position, the main power supply and the standby power supply are disconnected. When the swing arm 3 is rotated to the first connection position, the main power supply is connected. When the swing arm 3 is rotated to the second connection position, the standby power supply is connected.

[0073] The specific control process is as follows:

[0074] When the swing arm 3 is in the double-split position, the power supply to both the normal and standby sides is disconnected, meaning that both main electromagnetic drive mechanisms 2 are in the second position. Figures 2-7 As shown, the two linkage assemblies 6 also move to the second position along with the main electromagnetic drive mechanism 2, and the two linkage assemblies 6 are in the first state. The sliding shaft 64 is located in the connecting section 1040 in the track groove 104. The limiting platform 711 of the jump buckle 71 in the two locking assemblies 7 respectively cooperates with the limiting shaft 32 at both ends of the swing arm 3, thereby locking the swing arm 3 in the double split position.

[0075] like Figure 8 As shown, when the power supply on the commonly used side needs to be turned on, that is, when the swing arm 3 needs to be driven to the first on position, the first coil 23 in the main electromagnetic drive mechanism 2 on the commonly used side is energized. The active iron core 25 on the commonly used side is driven to move in a straight line to the first position and stays in the first position. Then, through the second connecting rod 62 on the commonly used side, the connecting rod assembly 6 is moved to the first position, which in turn moves the sliding shaft 64 on the commonly used side from the connecting section 1040 of the track groove 104 to the first sliding section 1041 away from the connecting section 1040. The connecting rod assembly 6 on the commonly used side is always in the first state during this process. At the same time, The auxiliary moving iron core 52 of the auxiliary electromagnetic drive mechanism on the standby side is driven, causing the sliding shaft 64 on the standby side to move from the connecting section 1040 to the end of the second sliding section 1042 away from the connecting section 1040. The connecting rod assembly 6 on the standby side switches from the first state to the second state, reducing the overall length of the connecting rod assembly 6 on the standby side. This, in conjunction with the drive arm 3, rotates from the horizontal double-split position to the inclined first connected position. In the figure, the arm 3 is in the first connected position with the left lower and the right higher. It should be noted that during the closing process on the normal side, the two limit shafts 32 in the arm 3 and the limit platforms 711 of the two jump latches 71 always maintain a limit engagement.

[0076] like Figures 2-6, 8, when the normal side power supply needs to be disconnected, that is, the swing arm 3 is turned from the first on position to the double off position, the first off driving iron core 421 of the off electromagnetic mechanism 42 drives the tripping piece 41 to rotate first, thereby driving the normal side trip 71 to rotate, so that the limiting table 711 of the normal side trip 71 is separated from the limiting shaft 32 at one end of the swing arm 3, thereby avoiding the swing arm 3 from being limited by the trip 71 to rotate, and then the second coil 24 of the normal side is energized to drive the normal side driving iron core 25 to move to the second position, thereby driving the normal side connecting rod assembly 6 to move to the second position, at the same time, the sliding shaft 64 of the standby side is driven by the standby side auxiliary reset piece 53 to move from the second sliding section 1042 away from the one end of the connecting section 1040 to the connecting section 1040, and the limiting table 711 of the trip 71 in the standby side is always in limiting cooperation with the limiting shaft 32, the off electromagnetic driving mechanism stops energization, the off reset piece 43 drives the off driving iron core 421 to reset, and at the same time, the tripping piece 41 is also driven to rotate, so that when the swing arm 3 is turned from the first on position to the double off position, the swing arm 3 is rotated under the joint action of the two connecting rod assemblies 6, the normal side main electromagnetic driving mechanism 2 and the standby side locking assembly 7, thereby accelerating the off speed, and when the swing arm 3 is turned to the double off position, the limiting table 711 of the normal side trip 71 is again in limiting cooperation with one end of the swing arm 3, thereby locking the swing arm 3 to the double off position.

[0077] As shown in Figures 9-11 , when the standby side power supply needs to be connected, the swing arm 3 needs to be driven to the second on position, the first coil 23 of the main electromagnetic driving mechanism 2 of the standby side is energized, the driving iron core 25 of the standby side is driven to move along a straight line to the first position and is kept at the first position, thereby driving the connecting rod assembly 6 through the second connecting rod 62 of the standby side to move to the first position, thereby driving the sliding shaft 64 of the standby side to move from the connecting section 1040 of the track groove 104 to the first sliding section 1041 away from the connecting section 1040, and in this process, the connecting rod assembly 6 of the standby side is always in the first state, at the same time, the auxiliary driving iron core 52 of the auxiliary electromagnetic driving mechanism 5 of the normal side is driven, thereby driving the sliding shaft 64 of the normal side to move from the connecting section 1040 to the second sliding section 1042 away from the one end of the connecting section 1040, and the connecting rod assembly 6 of the normal side is switched from the first state to the second state, so that the overall length of the connecting rod assembly 6 of the normal side is reduced, thereby cooperating to drive the swing arm 3 to be turned from the horizontal double off position to the inclined second on position, in the figure, the swing arm 3 is in the second on position of the left high and the right low, and in addition, in the closing process of the standby side, the two limiting shafts 32 in the swing arm 3 and the limiting tables 711 of the two trips 71 always remain in limiting cooperation.

[0078] As shown in Figures 2-6When the spare side power supply needs to be disconnected, that is, the swing arm 3 is turned from the second on position to the double breaking position, the tripping piece 41 is first driven to rotate by the breaking moving iron core 421 of the breaking electromagnetic mechanism 42, thereby driving the spare side trip 71 to rotate, so that the limiting table 711 of the trip 71 is separated from the limiting shaft 32 at one end of the swing arm 3, thereby avoiding the trip 71 from limiting the rotation of the swing arm 3, and then the spare side second coil 24 is energized to drive the driving iron core 25 of the spare side to move to the second position, thereby driving the connecting rod assembly 6 of the spare side to move to the second position, at the same time, the sliding shaft 64 of the commonly used side is driven by the auxiliary reset piece 53 of the commonly used side to move from the second sliding section 1042 to the abutting section 1040, and the limiting table 711 of the trip 71 of the commonly used side is always in limiting cooperation with the limiting shaft 32, the breaking electromagnetic driving mechanism stops energization after the driving iron core 25 of the spare side moves to the second position, the breaking reset piece 43 drives the breaking moving iron core 421 to reset, and at the same time, the tripping piece 41 is also driven to rotate, so that when the swing arm 3 is turned from the second on position to the double breaking position, the swing arm 3 is turned to the horizontal breaking position under the joint action of the two connecting rod assemblies 6, the spare side main electromagnetic driving mechanism 2 and the commonly used side locking assembly 7, and the breaking speed is relatively fast, and when the swing arm 3 is turned to the double breaking position, the limiting table 711 of the trip 71 of the spare side is again in limiting cooperation with one end of the swing arm 3, thereby locking the swing arm 3 to the breaking position.
