[0024] Specifically, the housing 100 includes a bottom plate 1, columns 2, side plates 3, a top cover plate 4, and a back plate 5. The four corners of the bottom plate 1 are respectively connected and fixed to the four columns 2 with screws. The side plates 3 are connected and fixed to the columns 2 with screws. The back plate 5 is connected and fixed to the columns 2 with screws. The top cover plate 4 is fixed after the internal control board 11 is installed. The whole housing 100 is assembled by using an aluminum alloy structure tenon and mortise structure, meeting the process requirements and sealing measures of environmental strength, stiffness, and stability, ensuring the overall performance of the housing. It has the characteristics of being lightweight, high-strength, good corrosion resistance, and excellent processing performance. The aluminum alloy housing can effectively reduce the weight of the overall equipment while ensuring sufficient mechanical strength and heat dissipation capacity. It can be surface-treated according to customer requirements, such as spraying, anodizing, chrome plating, etc., to achieve functions such as beauty and anti-corrosion. The installation method can be designed and fixed diversely according to the overall structure form.

[0025] Further, the output mechanism may include an optical signal interface 9, an output sampling interface 10, and a power interface 8. To ensure the stable operation and mutual non-interference of the multi-channel output thyristor trigger device during operation, an insulating spacer 7 is added in the middle for isolation between the output sampling interface 10 and the machine housing. A groove surrounding it for one week is provided on the outside of the insulating spacer 7, increasing the overall creepage distance, effectively shielding the interference between signals, better isolating the high-voltage electric field effect generated during operation and controlling the safety distance, and effectively reducing the signal interference generated when the thyristor is input into the device.

[0026] Further, the power interface 8, the optical signal interface 9, and the output sampling interface 10 are all arranged on the same side of the housing. The control board 11 includes multiple units, and each unit is correspondingly connected to an output sampling interface 10. The optical signal interface 9 is located above the output sampling interface 10. The power interface 8 and the optical signal interface 9 are in the same row. The multiple optical signal interfaces 9 are arranged at intervals in a straight line, and the multiple output sampling interfaces 10 are arranged at intervals in a straight line. By adopting the modular design concept, the trigger device is divided into multiple independent modules, facilitating users to select and combine according to actual needs. At the same time, the modular design also facilitates subsequent maintenance and upgrading.

[0027] The trigger device provided by the embodiment of the utility model is designed for the need of precisely controlling multiple thyristors in the fields of power electronics and industrial automation. This device can generate multiple independent trigger signals to control different thyristors respectively, achieving precise control and stable operation of the circuit. Compared with the traditional trigger method, the multi-channel output thyristor trigger device has the advantages of high-precision control, high reliability, flexibility and intelligence. It improves the control precision and stability of the circuit by precisely controlling the parameters of the trigger signal, and adopts advanced isolation technology and protection measures to ensure the reliability and safety of the system. This device has a wide range of applications in power electronic devices such as variable frequency speed regulators and inverters. By precisely controlling the trigger timing and angle of multiple thyristors, it realizes smooth adjustment of the motor speed and conversion from direct current to alternating current. It can generate multiple independent and precisely controlled trigger signals, which act on different thyristors respectively, thus achieving high-precision control of the entire circuit system. This precise control helps to improve the operation efficiency and stability of the system.

[0028] In some embodiments, multiple grooves or protrusions are formed on the peripheral surface of the inner cavity of the housing 100, significantly increasing the heat dissipation area, enabling heat to be dissipated in a timely manner through heat conduction and convection. To ensure the normal use of the device in a harsh environment, potting glue can be used for potting to increase the overall insulation and sealing of the device.

Each output can be individually set with trigger parameters (such as trigger angle, trigger frequency, etc.) as needed, without interference. This design improves the flexibility and adaptability of the system and can meet complex and variable control requirements. In power electronic systems, such as three-phase bridge fully controlled rectifier circuits and multi-phase motor drives, multiple thyristors need to be controlled simultaneously, and this device can well meet these requirements.

[0032] 2. High-precision trigger control

[0033] Adopt high-precision time control technology and trigger signal processing technology to ensure that the waveform, amplitude and duration of the trigger pulse precisely meet the trigger requirements of the thyristor, thereby improving the precision and stability of trigger control. Specifically, a high-performance single-chip microcomputer or DSP can be used as the control core, combined with a precise clock source and signal conditioning circuit to achieve high-precision trigger control.

[0034] 3. Intelligent control

In power electronic systems that require intelligent control, such as smart grids, wind power converters, etc., this device can significantly improve the intelligent level and operating efficiency of the system.

[0036] 4. High-efficiency heat dissipation design

[0037] Regarding the heat problem that may occur during the triggering process of thyristors, a high-efficiency heat dissipation design is adopted, such as increasing the heat dissipation area, optimizing the heat dissipation path, using high-performance heat dissipation materials, etc., to ensure that the triggering device can still operate stably in a high-temperature environment. Specifically, heat dissipation components such as heat sinks, fans, and heat pipes can be used, combined with a reasonable air duct design and thermal management strategy to achieve high-efficiency heat dissipation.

[0038] 5. Modular design

[0039] Adopting the modular design concept, the triggering device is divided into multiple independent modules (such as power supply module, trigger signal generation module, drive module, etc.), which is convenient for users to select and combine according to actual needs. At the same time, modular design also facilitates subsequent maintenance and upgrade. In scenarios that require rapid response to market demands and customization requirements, such as industrial automation, power equipment manufacturing, etc., modular design can significantly improve the flexibility and market competitiveness of products.
