[0002] Thyristors are commonly used semiconductor devices widely applied in power regulation, control, and protection, especially in high-voltage, high-current power systems. To improve the operational stability of thyristor switches and ensure their normal operation in harsh environments, waterproof and dustproof design is crucial. Therefore, a thyristor switch with waterproof and dustproof features needs to be designed.
[0003] Most existing switching devices only serve the function of connecting switches. However, there may be internal defects in the devices. Therefore, it is necessary to install waterproof and dustproof devices on the equipment. Existing switching devices generate a lot of heat during operation. Therefore, the waterproof and dustproof devices also need to take into account heat dissipation performance. Heat dissipation devices should be installed on the original basis to ensure that the equipment can effectively dissipate heat in high-temperature environments, thereby maintaining a stable working state.

[0014] (III) Beneficial Effects
[0015] This utility model provides a thyristor switch with a waterproof and dustproof device, which has the following advantages:
[0016] 1. This thyristor switch with a waterproof and dustproof device, through the anti-slip mechanism, is designed to prevent water and dust from entering the connector when it is connected to an external device during operation. The connector and plug may be exposed. Therefore, a hinge is installed on the outside of the connector to prevent water and dust from entering. Protective covers A and B are installed on both sides of the hinge to cover and protect the connector. A wire hole is opened on the top surface of protective cover A, allowing the wire to enter the connection.
