[0002] With the continuous development of society and the economy, the demand for electrical semiconductor switches is increasing. Thyristor switches mainly consist of a switch body, main circuit and control circuit terminals, and a housing. The terminals are placed on circuit boards, which are axially aligned and connected by support pillars. However, current thyristor switches are cumbersome to install, and the valve assembly units are difficult to disassemble and maintain, leading to reduced work efficiency and space utilization.

[0022] Please see Figures 1-3 This is an integrated thyristor switching device, mainly comprising a thyristor module 1, a trigger module 2, an RC snubber module 3, and a voltage equalization module 4. The thyristor module 1 tightly presses together the upper fixing component 102, the lower fixing component 103, and the valve assembly 104 via a fixing rod 101, ensuring the stability of the press-fit. The upper fixing component 102 and the lower fixing component 103 not only serve a fixing function but also realize the circuit connection function; their input and output wire directions can be flexibly changed according to actual conditions. The lower fixing component 103 is designed as a single integral structure, while the upper fixing component 102 consists of two parts. This design facilitates uniform pressing of the valve assembly, thereby improving overall performance.

[0023] Trigger module 2 is fixed to thyristor module 1, and the two modules are secured together by a sealing plate to achieve effective separation of high and low voltage. RC snubber module 3 is installed on one side of thyristor module 1 to provide RC snubber; voltage equalization module 4 is installed on the other side of thyristor module 1 to stabilize the voltage. This modular layout not only improves the space utilization of the device but also greatly facilitates subsequent disassembly and maintenance.

[0024] The detailed structure of thyristor module 1 is further shown. The upper fixing component 102 and the lower fixing component 103 are tightly connected by a fixing rod 101, while the valve assembly 104 is firmly pressed into the middle. This design not only ensures the stability of the structure but also allows the direction of the inlet and outlet lines to be adjusted according to actual needs. The integral design of the lower fixing component 103 enhances its structural strength, while the two-piece design of the upper fixing component 102 facilitates more uniform valve assembly pressing.

[0025] The thyristor module 1 also includes an inlet assembly and an outlet assembly. The inlet assembly is cleverly separated into left and right components, which are connected by an overlapping strip to ensure the stability of the crimped fastening. The inlet and outlet assemblies also provide additional fixation for the overall device, further increasing its stability.

[0026] Trigger module 2 is fixed to thyristor module 1, and the two modules are separated by a sealing plate. This design ensures effective separation of high and low voltages and improves the safety of the device. RC absorption module 3 and voltage equalization module 4 are respectively installed on both sides of thyristor module 1. This layout not only facilitates disassembly and maintenance but also significantly improves the space utilization and safety performance of the device.

[0027] Overall, this utility model's integrated thyristor switching device achieves close cooperation and efficient collaboration among its components through a modular design. This design not only improves the structural stability and space utilization of the device but also greatly simplifies subsequent disassembly and maintenance, reduces operating costs, and enhances the overall aesthetics.

[0028] In summary, this utility model of an integrated thyristor switch device, while meeting electrical performance requirements, achieves advantages such as small space occupation, high safety performance, easy maintenance, and compact structure through innovative structural design, and has high practical value and market promotion prospects.
