[0002] Thyristor is a high-power electrical component, also known as thyristor. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power driver to control high-power equipment with low-power controls. It has been widely used in AC and DC motor speed control systems, power control systems and follow-up systems.

[0003] The existing thyristors generate a lot of heat during operation. At the same time, the components in the equipment area are densely arranged, which causes the thyristors to heat up and heat up during operation. If the temperature of the thyristors is too high, the life of the devices will be shortened, and even the devices will be burned and cause danger. Therefore, it is necessary to detect and control the temperature of the thyristors during operation. Utility Model Content

[0011] Furthermore, the thermal conductive wire is made of aluminum material, and the center of the thermal conductive wire is a hollow structure.

The end is located on the inner wall of the processing chamber 6, and can be connected to the processing chamber 6 through the arranged heat-conducting wire 5. Since the heat-conducting wire 5 has good thermal conductivity, if the thyristor valve 4 is overheated and catches fire, the sealing wax 10 can be melted, and then the dry powder in the dry powder fire extinguishing chamber 8 can be sprayed out through the gas in the airbag body 7, so that the fire point can be quickly extinguished to avoid unnecessary losses caused by untimely fire extinguishing. The heat-conducting wire 5 is made of aluminum material, and the center of the heat-conducting wire 5 is a hollow structure.
