[0002] A three-phase integrated switch is a switching device capable of simultaneously controlling the on / off state of three-phase circuits. It typically consists of three independent single-pole switches, each controlling the on / off state of one phase of the circuit. This design makes operation flexible and convenient, meeting the control requirements of different electrical systems.

[0003] Three-phase integrated switches have wide applications in electrical systems, including:

[0004] Industrial production lines: Commonly used to control the starting and stopping of three-phase equipment such as motors. By properly configuring switches, automated control of the equipment can be achieved, improving production efficiency.

[0005] Power systems: Used for the protection and control of critical equipment such as distribution cabinets and transformers. In the event of a fault, the switch can quickly cut off the circuit, protecting equipment and personal safety.

[0006] Building electrical systems: commonly used for controlling electrical equipment such as lighting and air conditioning. Through the coordination of intelligent control systems and switches, energy conservation and comfort control of buildings can be achieved.

The transmission shaft device is rotatably mounted on the base. Three transmission crank arms are provided at positions corresponding to each knife switch assembly on the transmission shaft device. One end of each linkage device is hinged to the corresponding knife switch assembly, and the other end is hinged to the corresponding transmission crank arm. The transmission shaft device is also provided with a self-locking crank arm. One end of the self-locking spring is hinged to the self-locking crank arm, and the other end is hinged to the base.

[0008] The aforementioned patents have some advantages, but also some problems, such as their inability to achieve precise control. Utility Model Content

[0009] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a three-phase multi-group heavy-load integrated switch to solve the problems mentioned in the background art.

[0010] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0011] A three-phase multi-group heavy-duty integrated switch includes an insulating fixed cylinder, lead terminal fixing plates and mounting bases fixedly connected to the front and rear of the insulating fixed cylinder, respectively. A rotatable insulating moving contact wheel is provided in the annular space gap between the insulating fixed cylinder, the lead terminal fixing plates, and the mounting base, which are integrally formed. The central axis of the insulating moving contact wheel coincides with the central axis of the annular space within the integral structure. The front and rear ends of the insulating moving contact wheel are symmetrically fixed with end permanent magnet rotors and tail permanent magnet rotors. End bearings and tail bearings are also fixedly mounted at the front and rear ends of the insulating moving contact wheel. An end electromagnet assembly is provided on the insulating fixed cylinder, with a gap between it and the end permanent magnet rotor. The insulating fixed cylinder is also equipped with a tail electromagnet assembly that is gapped with the tail permanent magnet rotor. The insulating moving contact wheel is equipped with a three-phase moving contact assembly. The insulating fixed cylinder is equipped with a first-phase static contact assembly, a second-phase static contact assembly, and a third-phase static contact assembly. The three-phase moving contact assembly has a moving contact wire bundle assembly that is independently and fixedly connected to each other.

[0012] By adopting the above technical solution, this three-phase multi-group heavy-load integrated switch achieves the effect of multi-group heavy-load integrated control. During the process of integration and precise control, no misalignment occurs. The end permanent magnet rotor and end electromagnet group on the insulated fixed cylinder can form a stepper motor, and the tail permanent magnet rotor and tail electromagnet group on the insulated fixed cylinder can form another stepper motor. The end electromagnet group and tail electromagnet group are connected to electrical components such as the PLC controller through electromagnet wires and electromagnet lead terminals, thus facilitating automated integrated control. Furthermore, the angles of the end electromagnet group and tail electromagnet group in this three-phase multi-group heavy-load integrated switch are different from the end permanent magnet and tail permanent magnet by a certain angle, ensuring precise control during reverse or forward rotation without misalignment. The external PLC controller can control the attraction and repulsion of the electromagnets in the end electromagnet group and tail electromagnet group to control the rotation position of the rotating rotor. The symmetrical two-group structure improves the precision control capability. The three-phase moving contact group, together with the first-phase static contact group, the second-phase static contact group, and the third-phase static contact group on the insulating fixed cylinder, precisely switches on and off to achieve control.

[0015] Preferably, the stationary contact wire output terminal fixing post is fixed to the three-phase contact fixing plate by a fixing nut.

[0016] By adopting the above technical solution, fixing can be achieved quickly using a fixing nut, which facilitates assembly and disassembly.

[0017] Preferably, the first phase static contact group, the second phase static contact group, and the third phase static contact group are respectively fixedly connected to the first phase static contact wire output terminal, the second phase static contact wire output terminal, and the third phase static contact wire output terminal mounted on the static contact wire output terminal fixing post via wires.

[0018] By adopting the above technical solution, the ease of external connection can be improved by using the first phase stationary contact wire output terminal, the second phase stationary contact wire output terminal, and the third phase stationary contact wire output terminal.

[0019] Preferably, the lead terminal fixing plate is provided with a three-phase moving contact lead terminal and an electromagnet wire output terminal group.

[0020] By adopting the above technical solution, space can be saved by setting the three-phase moving contact lead terminals and electromagnet wire output terminal group on the lead terminal fixing plate.

[0021] Preferably, the tail electromagnet assembly and the end electromagnet assembly are respectively connected to lead-out electromagnet wires, and the electromagnet wires are located outside the insulating fixed cylinder.

[0022] By adopting the above technical solution, it is easy to connect to electricity using an externally introduced electromagnet wire.

[0023] Preferably, the insulated moving contact wheel is further provided with a continuously conducting moving contact group.

[0024] By adopting the above technical solution, the setting of the continuous conduction moving contact group is convenient for control.

[0025] Preferably, the first phase static contact group, the second phase static contact group, and the third phase static contact group are each multiple groups.

[0026] Preferably, the end electromagnet assembly and the tail electromagnet assembly are respectively connected to the corresponding control terminals of the PLC controller.

[0029] This three-phase multi-group heavy-load integrated switch achieves integrated control of multiple heavy-load groups, enabling precise control without misalignment. The end permanent magnet rotor and end electromagnet group on the insulated fixed cylinder form a stepper motor, while the tail permanent magnet rotor and tail electromagnet group on the insulated fixed cylinder form another stepper motor. The three-phase moving contact leads can be connected to a PLC controller for convenient control. Furthermore, the end and tail electromagnet groups in this three-phase multi-group heavy-load integrated switch are angled differently to ensure precise control during reverse or forward rotation, preventing misalignment. The external PLC controller controls the attraction and repulsion of the electromagnets in the end and tail electromagnet groups to control the rotational position of the rotor. The symmetrical two-group structure enhances precise control. The three-phase moving contact group works in conjunction with the first, second, and third phase static contact groups on the insulated fixed cylinder to achieve control.
