[0045] Specifically, to prevent power switching failures caused by external environmental factors, such as dust, moisture, and mechanical shock, which could directly damage the dual power switching module 300, such as... Figure 2 As shown, the second housing 330 can be fitted onto the outer surfaces of the first magnetically controlled circuit breaker 310 and the second magnetically controlled circuit breaker 320, and connected to them. This provides additional fixation for the dual-power switching module 300 and also offers additional mechanical support, ensuring its stable position within the dual-power switching device. Furthermore, by placing the metal component 340 between the second housing 330 and the outer surface of the second magnetically controlled circuit breaker 320, the opening states of the first and second magnetically controlled circuit breakers 310 and 320 can be restricted, thus forming a mechanical interlock structure for the dual-power switching device.

The two ends of the metal rope 342 are connected to the first magnetically controlled circuit breaker 310 and the second magnetically controlled circuit breaker 320 by screws and terminals.

[0048] It should be noted that since the length of the metal rope 342 is fixed, when the two magnetic contactors are closed at the same time, the metal rope 342 will be tightened under the length limitation, thereby preventing the first magnetic contactor 310 and the second magnetic contactor 320 from being closed at the same time, and preventing the equipment from malfunctioning.

[0051] It should be noted that by separately opening the first door plate 140, the second door plate 150 and the third door plate 160, the modules and interfaces that need to be maintained, repaired or connected can be directly accessed, without the need to disassemble the entire first shell 100 or move other devices in the first shell 100, thereby reducing the maintenance time or connection time of the dual power switching device. In addition, when the devices or modules that need to be accessed, connected or maintained are not needed, the first door plate 140, the second door plate 150 or the third door plate 160 can be closed and locked to prevent electric shock, misoperation or other safety accidents, and the first door plate 140, the second door plate 150 or the third door plate 160 can be provided with warning signs or safety locks, etc., to further improve the safety of the dual power switching device.

[0053] The first door plate 140 can further be provided with a display unit 142, the display unit 142 being electrically connected with the dual power switching module 300, part or the whole of the display unit 142 being exposed from the inside of the first door plate 140, and whether the ABC three-phase of the power generation side, the commercial power side and the load side is live can be displayed for observation by the staff, so that problems can be found in time and corresponding measures can be taken, thereby enhancing the real-time monitoring capability of the dual power switching device and improving the safety performance of the dual power switching device.

[0054] The embodiment of the application further provides a dual power switching method. It should be noted that the dual power switching device of the embodiment of the application can be used to execute the dual power switching method provided by the embodiment of the application. The dual power switching method provided by the embodiment of the application is introduced below.

[0055] Figure 8 is a flowchart of the dual power switching method provided by the embodiment of the application, as shown in Figure 8 the method comprises the following steps:

[0056] In step S801, the interlocking states of the first magnetic control circuit breaker and the second magnetic control circuit breaker in the dual power switching module are acquired, wherein the interlocking states include electrical interlocking and mechanical interlocking.

[0057] Specifically, the electrical interlocking is an interlocking mechanism realized through an electrical signal, and the mechanical interlocking refers to preventing two circuit breakers from being in a closed state at the same time through a physical way. In order to ensure the continuous power supply and stable operation of the power utilization equipment, a dual power switching device containing the dual power switching module can be set, when the main power supply fails, the dual power switching module can immediately switch the power supply, thereby avoiding system downtime caused by single point failure, and also avoiding equipment downtime or data loss caused by power supply problems. When power transmission is performed using the above device, first, the interlocking states of the first magnetic control circuit breaker and the second magnetic control circuit breaker in the dual power switching module are acquired, and then the dual power switching is performed under different interlocking states.

[0058] Step S802, in the case of electrical interlocking, a first switching control signal is obtained, and the first magnetic contact breaker and the second magnetic contact breaker are switched according to the first switching control signal to obtain a first operation result and a second operation result, wherein the first switching control signal is used to trigger the switching action of the first magnetic contact breaker and the second magnetic contact breaker, the first operation result includes an open state or a closed state, and the second operation result includes an open state or a closed state.

[0059] It should be noted that the above-mentioned dual power switching device includes a power side interface and a load side interface, the power side interface is connected with two power supplies, the load side interface is connected with an electrical equipment, the power side interface includes a commercial power side interface and a power generation side interface, the first magnetic contact breaker is connected with the commercial power side interface, and the second magnetic contact breaker is connected with the power generation side interface. If the interlocking state is electrical interlocking, when one power supply normally supplies power, the first magnetic contact breaker is in a closed state, and the second magnetic contact breaker is in an open state.

The electrical interlocking can also effectively prevent power conflicts caused by misoperation or faults, meet the use requirements of the low-voltage magnetic contact breaker in the dual power uninterrupted power supply line, and improve the safety and reliability of the system.

[0068] Specifically, the pre-tight state refers to a state of the metal rope being neither relaxed nor tight.
