★ A rectifier is a controlled rectifier that converts AC to DC power using a silicon controlled rectifier (SCR) based on a silicon controlled rectifier (SCR) and a core intelligent digital control circuit. It is also known as a thyristor rectifier, SCR rectifier, or electroplating rectifier. It boasts numerous advantages, including high efficiency, no mechanical noise or wear, fast response, small size, and light weight.
★SCR Rectifier: The main circuit adopts a three-phase bridge or double-anti-star circuit with balancing reactors (or a three-phase five-limb type). High-power SCR components are used, resulting in significant energy savings. The main control system uses a large-board, high-threshold, anti-interference, large-scale integrated control board; all modules and integrated components are imported, ensuring high reliability. It features automatic voltage and current regulation with a stability accuracy better than 1%. It has 0~60S soft start, and the electroplating oxidation coloring time can be arbitrarily set with automatic timing. Multi-phase rectification reduces the output voltage ripple coefficient ru, making it particularly suitable for hard chrome plating processes, resulting in good surface finish and uniform plating thickness. Cooling methods: water cooling, air cooling, and self-cooling.
★ A thyristor, also known as a silicon controlled rectifier (SCR), is a power semiconductor device. It boasts numerous advantages, including large capacity, high efficiency, excellent controllability, long lifespan, and small size, serving as a bridge between low-voltage control and controlled high-voltage systems. From an energy-saving perspective, power electronics technology is hailed as a new electrical technology. my country's energy utilization rate is relatively low; calculated by per unit of GDP, my country's energy consumption is 4.98 times that of France and 4.43 times that of Japan. Therefore, the widespread use of electrical control devices centered on thyristors (SCRs) is an important measure for effectively saving electricity in my country.
★ Thyristors (Semiconductors with Resistants): In my country's industrial, agricultural, and civilian production, they are mainly used in AC voltage regulation, controlled rectification, and contactless static power switches. AC voltage regulation utilizes the switching characteristics of thyristors (Semiconductors with Resistants) to replace older contact voltage regulators, induction voltage regulators, and reactors. The conversion between AC and variable AC voltage using thyristors (Semiconductors with Resistants) is called AC voltage regulation. It is mainly used in temperature control, lighting control, and AC motor speed regulation. Controlled rectification uses rectifiers composed of thyristors (Semiconductors with Resistants) to easily change the DC output voltage while keeping the AC voltage constant. Thyristor-controlled rectification has replaced DC generator sets in DC drive speed control devices and is widely used in steel rolling, electrolysis, electroplating, machine tools, papermaking, textiles, and excitation fields.
