Power regulator is a thyristor (thyristor) based on the intelligent digital control circuit as the core of the power control appliance, referred to as the power regulator. The power regulator has many advantages, such as high efficiency, no mechanical noise and wear, fast response speed, small size and light weight. The following describes the thyristor of the power regulator.
Thyristor, full name of thyristor (also known as thyristor, abbreviated SCR), is a power semiconductor device. It has many advantages such as large capacity, high efficiency, good controllability, long life and small size, and is a bridge between weak current control and controlled strong current. From the point of view of energy saving, power electronics technology is known as a new electrical technology. China's energy utilization rate is low, according to the national production per unit energy consumption calculation, China is 4.98 times of France, Japan's 4.43 times, so the popularity of thyristor (thyristor) as the core of the electrical control device is an important measure to effectively save energy in our country.
What are the precautions for the use of power regulator
Thyristor (SCR) is mainly used in the fields of AC voltage regulation, controllable rectification and contactless power static switch in China's industrial and agricultural production and civil use. Ac voltage regulation is to use the switching characteristics of thyristor (thyristor) to replace the old-fashioned contact regulator, induction regulator and reactor voltage regulation, and use thyristor (thyristor) to achieve the conversion between AC and variable AC called AC voltage regulation.
It is mainly used in temperature control, lighting control and AC motor voltage regulation and other fields. Controlled rectifier is the rectifier composed of thyristor (thyristor) can easily change the size of DC output voltage under the condition of constant AC voltage, that is, controlled rectifier. Thyristor controlled rectifier has replaced DC generator set for DC drive speed control device, widely used in steel rolling, electrolysis, electroplating, machine tools, paper making, textile, excitation and other fields.
