The thyristor module, commonly known as the thyristor module, is a kind of electronic circuit that can work under high voltage and high current conditions, and is widely used in electronic circuits such as controllable rectification, AC voltage regulation, contactless electronic switches, inverters and frequency conversion. Become an indispensable important component in some circuits. Of course, in order to make it play a greater use value, there are still many things to pay attention to when using thyristor modules.
Common sense of using thyristor module:
1. When selecting the rated current of the thyristor module, it is necessary to pay attention to not only the average current through the component, but also the conduction angle during normal operation, the heat dissipation and ventilation conditions and many other factors. At the same time, the tube The case temperature must not exceed the allowable value under the corresponding current.
2. When using the thyristor module, use a multimeter to check whether the thyristor module is in good condition. If a short circuit or open circuit is found, it must be replaced immediately.
3. It is strictly forbidden to use a megohmmeter to check the insulation of components.
4. The thyristor module with power above 5A should be equipped with a radiator and ensure the specified cooling conditions. At the same time, in order to ensure good contact between the radiator and the core of the thyristor module, a layer of silicone oil or Silicone grease to help better heat dissipation.
5. Use overvoltage and overcurrent protection devices for the thyristor modules in the main circuit in accordance with regulations.
6. Prevent the forward overload and reverse breakdown of the control pole.
The above common sense when using the thyristor module must be understood, only in this way can the normal operation of the thyristor module be guaranteed.
