Thyristor power controller is widely used, which is a kind of energy-saving and environmental protection products. It is used in various industrial devices, such as high temperature boilers, glass tempering furnaces, high temperature ceramic kilns, metal heat treatment equipment, heating equipment, dyeing equipment, physical equipment, chemical equipment, electric power transmission equipment type transformer primary side control, will use thyristor power controller. Now let me introduce you the notes when use of thyristor power controller.
Specific points of attention are as follows:
1. In the use of the power controller, the internal thyristor power electronic devices need a good heat dissipation environment. It is necessary to ensure that this product is used under conditions that meet the ambient temperature range to ensure its reliable operation. A safe operating environment can ensure the safety of the thyristor power controller and extend the service life.
2. Power controller has zero crossing control, phase angle trigger control two control methods, the specific use of which need to be determined according to the control requirements, load characteristics and control process. Only the control mode and control requirements match, in order to achieve the desired control effect.
3. The selection of thyristor although there are certain safety factors (the average conduction current of thyristor is 1.5-2 times the actual average current, the maximum withstand voltage is 2-3 times the actual maximum voltage), but still need to take some protective measures, generally using automatic air switches and fast fuses for overcurrent protection, resistance absorption device and capacitor overvoltage protection, Cut off when not in use.
4. Thyristor power controller has been widely used in electric heating industry. It is a closed-loop temperature control system. Need temperature detection element, feedback element and heating furnace system coordination. If you are not clear about your load process and characteristics, we can also provide you with customized electric heating thyristor power controller system solutions.
