KTZ-260/400

Electric heating rectifier for preheating furnace

A thyristor rectifier is a rectifier device that uses the semiconductor principle of silicon to convert alternating current into direct current. The PCVD preheating furnace temperature control system adopts a thyristor rectifier circuit, which features high rectification efficiency, large power, low noise, small size, easy operation and maintenance. One device provides 1 main terminal DC power supply, 1 gas terminal DC power supply, and 1 pump terminal DC power supply, among which: The electric heating rectifier of the preheating furnace provides three DC power supplies. Among them, the main heating system of the preheating furnace body adopts a three-phase fully controlled bridge rectifier circuit, and the temperature compensation systems at the gas end and pump end of the furnace body also adopt It is a single-phase fully controlled bridge rectifier circuit.

Medium Frequency Heating Power Supply for Locomotive Wheel rims

A medium-frequency power supply is a power device that converts a 50-hertz industrial frequency power supply into the required frequency through a thyristor inverter. It is widely applied in industrial fields such as smelting, induction heating, metal surface quenching, forging, smelting, precision casting, welding, and piping. The KGPS series medium frequency power supply I produce adopts the most advanced control technology and production process in China at present. It has the following features:<br /> 1.Digital circuits, as the control core, have the advantages of strong control ability, good anti-interference performance, and few peripheral discrete components. The entire control circuit is installed on a 268mmx225mm printed circuit board, and the number of connections with the main circuit is reduced to only twenty-seven. The main components are all imported parts and are assembled after strict aging and screening, so the reliability is very high.<br /> 2. The control board eliminates the large-sized synchronous transformer and various other control transformers in the rectifier circuit. It does not recognize the phase sequence, further simplifying the overall circuit and reducing the equipment volume. It also has a complete set of multiple protection measures such as overcurrent, overvoltage, phase loss and low water pressure. The protection action is rapid. Once a circuit fault occurs, the system can act in a very short time to reliably protect the thyristor and capacitor from damage.<br /> 3. It adopts zero-voltage swept-frequency soft start and a dual closed-loop regulation system with current negative feedback and voltage negative feedback, enabling the power supply to start reliably in actual use. It has excellent current and voltage cut-off effects and features no impact during start-up and constant power regulation.
