The dual power transfer switch proposed by the present disclosure is described in detail below with reference to exemplary embodiments. It should be noted that the described embodiments are only some of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

A dual power transfer switch is used to switch between two power sources. The dual power transfer switch may be of various types. A dual power transfer switch of some type is capable of switching between a first power on position in which only a first power source is turned on, a second power on position in which only a second power source is turned on, and a dual split position in which neither the first power source nor the second power source is turned on. The dual power transfer switch herein is not limited to this type.

Referring to fig. 1, a general schematic diagram of a dual power transfer switch as proposed by the present disclosure is shown. It can be seen that the dual power transfer switch includes three main parts, namely a mechanism module 1, a switch module 2 and a controller 3, which can be fixed together by threads or other connection means.

The mechanism module 1 is provided with a mechanism for supplying and transmitting power, and a driving member 11 for driving the switch module 2. The mechanism module 1 may be provided with an electric drive, such as a motor or an electromagnet, for electric operation. Or may be provided with a handle for manual operation. In electrical operation, an electrical actuator in the mechanism module 1 drives the mechanism to store energy, and after the mechanism is released, it drives the drive member 11. The mechanism may also directly drive the driver 11. The driver 11 transmits the power further to the follower 24 of the switch module 2. In manual operation, the handle in the mechanism module 1 is moved by the operator, and the mechanism charges energy and then releases energy to drive the driving member 11. The mechanism may also directly drive said driving member 11. The driver 11 transmits the power further to the driven member 24 of the switch module 2.

The switch module 2 is provided with a first power supply line terminal 21 connected to said first power supply, a second power supply line terminal 22 connected to said second power supply, and a load terminal 23 connected to a load. Furthermore, the switch module 2 is provided with the aforementioned driven member 24, and the driven member 24 is configured to be driven by the driving member 11 of the mechanism module 1, so as to switch the dual power transfer switch between different positions, and realize the switching of the first power switch and the switching of the second power switch. The first and second power supplies described herein are not shown in the drawings and may be any type of power supply, such as mains, backup power, etc. The loads (also not shown in the figures) described herein may cover multiple types of powered devices.

A controller 3 is coupled to the mechanism module 1 to control the operation of the mechanism module 1 and thus the switching of the dual power transfer switch. The controller 3 can be configured to control the timing of the execution of the automatic switching, the switching scheme, and the like. Wherein the controller 3 may be wired to the mechanism module 1. Optionally, the controller 3 may be provided with a display screen 31.

Fig. 2 schematically shows the matching relationship between the mechanism module 1 and the switch module 2 of the dual power transfer switch. The mechanism module 1 and the switch module 2 are preferably arranged side by side and are fixed to one another by additional fastening means, and the drive element 11 of the mechanism module 1 engages the driven element 24 of the switch module 2 and thus moves it. Additional securing structures here may include bolts, screws, or other fasteners.

In the drawings, a part of the switch module 2 is represented by a dotted line in order to make the "follower" more clearly shown. But the dashed line may actually be a solid line, particularly if the "follower" is provided inside the switch module 2. In addition, the broken line portion of the switch module 2 shown in the figure near the mechanism module 1 may also be an independent part, which plays a role of installation, decoration, etc. for the switch module 2 and the mechanism module 1.

In order to make the dual power transfer switch usable in a variety of different situations, the present disclosure proposes to enable both sides of the mechanism module 1 to be provided with the driving part 11, and to enable both sides of the switch module 2 to be provided with the driven part 24 driven by the driving part 11. Thus, according to the needs of practical application occasions, the dual-power transfer switch can be easily assembled into a mechanism module 1 on the left and a switch module 2 on the right, or assembled into a mechanism module 1 on the right and a switch module 2 on the left, so as to meet different requirements.

The driving/driven members can be arranged on both sides of the mechanism module 1/switch module 2, and the following two schemes can be realized.

The first is that the driver/follower can be detachably mounted to the mechanism module 1/switch module 2 at either side of the mechanism module 1/switch module 2.

According to an alternative, the mechanism module 1 is provided with mounting portions near both sides thereof, and such that the driving member 11 can be detachably mounted to either of the mounting portions. Similarly, the switch module 2 is provided with mounting portions near both sides thereof, and the follower 24 is detachably mountable to any one of the mounting portions of the switch module.

Thus, when it is desired to achieve the effect of assembling the mechanism module 1 on the left and the switch module 2 on the right, it is only necessary to mount the driving member 11 on the right side of the mechanism module 1 and mount the driven member 24 on the left side of the switch module 2, and if the application is changed, it is desired to change the dual power transfer switch to have the mechanism module 1 on the right and the switch module 2 on the left, it is only necessary to detach the driving member 11 from the right side of the mechanism module 1 and mount the driven member 24 from the left side of the switch module 2 and mount the driven member 24 on the right side of the switch module 2. Wherein fig. 4A shows the driving member 11 of the mechanism module 1 on the right side of the mechanism module 1, and fig. 4B shows the driving member 11 of the mechanism module 1 detached from the right side and arranged on the left side of the mechanism module 1. Fig. 5A shows the follower 24 of the switch module 2 on the left side of the switch module 2, and fig. 5B shows the follower 24 of the switch module 2 detached from the left side and arranged on the right side of the switch module 2.

The second is that both sides of the mechanism module 1 are provided with driving parts 11, and both sides of the switch module 2 are provided with driven parts 24. With this solution, the driving member 11 and the driven member 24 may not have a detachable property, but may be directly fixedly mounted to both sides of the corresponding module. Fig. 6 shows an embodiment in which the drive element 11 is arranged on both sides of the mechanism module 1, and fig. 7 shows an embodiment in which the driven element 24 is arranged on both sides of the switch module 2.

After assembling both the mechanism module 1 and the switch module 2, the controller 3 may be provided in a separate arrangement (the controller 3 is separated from both the mechanism module 1 and the switch module 2) or in an integral arrangement (the controller 3 is fixed to a combined structure formed by the mechanism module 1 and the switch module 2) with respect to both the mechanism module 1 and the switch module 2, so as to be suitable for different application occasions. Fig. 3B and 3D show the split arrangement, and fig. 3A, 3C, 3E, 3F and 3G show the integrated arrangement. For the solution in which the controller 3 is arranged integrally with respect to both the mechanism module 1 and the switch module 2, the controller 3 may be located on the side of the mechanism module 1 remote from the switch module 2, or may be located on the side of the switch module 2 remote from the mechanism module 1. In addition, the controller 3 may also be incorporated in the switch module 2, and the display screen 31 of the controller 3 is exposed from the switch module 2, as shown in fig. 3H, for example.

As mentioned before, the switch module 2 comprises a first power supply line terminal 21 connected to said first power supply, a second power supply line terminal 22 connected to said second power supply, and a load terminal 23 connected to a load. Wherein fig. 1 shows that the first power supply inlet terminal 21 and the second power supply inlet terminal 22 are arranged at the top of the switch module 2 and the load terminal 23 is arranged at the bottom of the switch module 2. However, depending on the specific application, the first power supply line terminal 21 and the second power supply line terminal 22 may be disposed at the bottom of the switch module 2, and the load terminal 23 may be disposed at the top of the switch module 2.

In addition, the dual power transfer switch provided by the present disclosure further includes a voltage sampling line 4, which provides real-time information of electrical parameters such as power supply, voltage, frequency, etc. for the controller, and provides power for the mechanism module of the ATSE. Voltage sampling lines 4 are drawn outside of the modules in the figures for clarity of presentation. The voltage sampling lines 4 may be embedded inside these modules.
