Description

Technical Field

[0001] This utility model belongs to the field of switchgear technology, and more specifically, relates to a novel electric commutator. Background Technology

[0002] The new type of electric commutator uses electric operation to achieve remote control, and is used for circuit connection and phase sequence switching under no-load conditions. Current commutator switches have the following drawbacks:

[0003] Current phase-changing switches all use complex mechanical structures to connect circuits and switch phase sequences. They are all operated manually and cannot be remotely controlled. They also have problems such as large size and short service life.

[0004] Therefore, we propose a novel electric commutator to solve the above problems. Utility Model Content

[0026] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, a novel electric phase commutator includes a base plate 1, multiple partitions 2, a near-end lead wire, an out-end lead wire, and a rotating drum 8. The partitions 2 are used to fix the multiple near-end leads wire and the out-end leads wire between two partitions 2 respectively. The rotating drum 8 is provided through the multiple partitions 2. The near-end leads wire and the out-end leads wire are respectively in contact with the conductive plate inside the rotating drum 8.

[0029] Among them, such as Figure 1 As shown, the proximal leads include a first proximal lead 3 and a second proximal lead 4, and the exit leads include a first exit lead 5 and a second exit lead 6. The first proximal lead 3 and the second proximal lead 4 are located on the same side, and the first exit lead 5 and the second exit lead 6 are located on the same side; the first proximal lead 3 and the first exit lead 5 are installed opposite each other and are clamped and fixed by two partitions 2, and the second proximal lead 4 and the second exit lead 6 are installed opposite each other and are clamped and fixed by two partitions 2.

[0030] In this embodiment, as Figure 2 As shown, the partition 2 is provided with a slot, through which the proximal lead wire and the output lead wire are clamped and fixed. The proximal lead wire and the output lead wire can be fixed by clamping two adjacent partitions 2 together, thereby ensuring the stability of the connection between the proximal lead wire and the output lead wire.

[0031] In this embodiment, as Figure 1 As shown, the bottom of the partition 2 is fixedly connected to the base plate 1. Specifically, the partition 2 is fixedly connected to the base plate 1 through the screw holes at the bottom and bolts, thereby ensuring the stability of the entire commutator device.

[0032] In this embodiment, as Figure 2 As shown, the proximal lead and the output lead are connected to the conductive plate inside the rotating drum 8 via a moving contact 31, and a spring piece 9 is provided inside the moving contact 31. When the proximal lead and the output lead are connected to the conductive plate inside the rotating drum 8 via the moving contact 31, the spring piece 9 provides a certain contact pressure to the moving contact 31 to achieve a quick connection.

[0033] In this embodiment, as Figure 2 and Figure 3 As shown, the rotating drum 8 is rotatable, and has round shafts at both ends, one end of which is used to connect to the output shaft of the motor 7. The motor 7 is fixed to one side of the partition 2. Specifically, the motor 7 drives the round shaft of the rotating drum 8 to rotate, thereby realizing the phase commutation operation.

[0034] In this embodiment, as Figure 3 As shown, the rotating drum 8 is provided with a straight conductive plate and a cross conductive plate, which are arranged at 90° to each other. Specifically, the straight conductive plate includes a first straight conductive plate 81 and a second straight conductive plate 82, which have exposed conductive parts; the cross conductive plate includes a first cross conductive plate 83 and a second cross conductive plate 84, whose exposed conductive parts are arranged crosswise.

[0035] Furthermore, the straight conductive plate and the cross conductive plate are integrally molded and fixed from DMC material to form a rotating drum. DMC material has excellent insulation properties, as well as superior mechanical properties. DMC material is also adaptable to various molding processes, such as compression molding and injection molding, which can meet the performance and production process requirements of different products.

[0036] The specific working process of the commutator of this utility model is as follows:

[0037] When the electric commutator is in positive phase conduction, the first straight conductive plate 81 and the second straight conductive plate 82 inside the rotating drum 8 are in a horizontal position, so that the exposed conductive parts of them contact the moving contacts on the inlet and outlet leads. A spring 9 is also provided behind the moving contact to provide a certain contact pressure to the moving contact, so as to connect the first proximal lead 3 with the first outlet lead 5 and the second proximal lead 4 with the second outlet lead 6.

[0038] When the electric commutator switches from the positive phase conduction position to the commutation position, the motor 7 rotates and drives the rotating drum 8 to rotate 90° counterclockwise, so that the first cross conductive plate 83 and the second cross conductive plate 84 inside the rotating drum 8 are in a horizontal position, and their exposed conductive parts contact the moving contacts on the inlet and outlet leads, so that the first proximal lead 3 is connected to the second outlet lead 6, and the second proximal lead 4 is connected to the first outlet lead 5.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
