The all-solid-state induction heater equipment produced by Kehua is a kind of three-phase power frequency alternating current, which is rectified into direct current, and then the direct current is converted into an adjustable current to supply the alternating current flowing through the capacitor and the induction coil. High-density magnetic lines of force are generated in the induction coil, and the metal material contained in the induction coil is cut, resulting in a large eddy current in the metal material. All-solid-state induction heater equipment Induction heating equipment This eddy current also has some properties of intermediate frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat. For example, if a metal cylinder is placed in an induction coil with alternating intermediate frequency current, the metal cylinder is not in direct contact with the induction coil, and the temperature of the energized coil itself is very low, but the surface of the cylinder is heated to the point of redness or even melting , and the speed of this redness and melting can be achieved as long as the frequency and the strength of the current are adjusted. If the cylinder is placed in the center of the coil, the temperature around the cylinder will be the same, and the heating and melting of the cylinder will not produce harmful gases or pollute the environment with strong light. All-solid-state induction heating power supply All-solid-state induction heating power supply refers to the induction heating power supply with various power transistors, such as MOSFET, IGBT and other power devices, also called modern induction heating power supply. The 'solid state' induction heating power supply is for the teacher thyristor and vacuum tube induction heating power supply. It has the advantages of small power supply, low loss, high inverter conversion efficiency, easy operation and control, and good safety. Features 1) The basic theory of the circuit has not changed much. Due to the use of new power devices, the circuit and implementation technology have been greatly developed; 2) The power rectifier and inverter circuit devices mostly use module devices instead of single power devices. In order to achieve greater power, series, parallel or series-parallel power devices are used; 3) A large number of digital integrated circuits and special-purpose integrated circuits are used in the control circuit and protection circuit, which simplifies the design of the circuit and improves the reliability of the system; 4 ) New circuit components, such as non-inductive capacitor modules, non-inductive resistors, power ferrite applications, etc.; 5) Wide frequency range, covering the range of intermediate frequency, high frequency, and super audio frequency from 0.1--400kHz; 6) Conversion efficiency High, energy saving is obvious. The load power factor of the transistor inverter can be close to 1, which can reduce the input power by 22%--30) and reduce the cooling water consumption by 44%--70%; 7) The whole device is compact in structure, which can be compared with electronic tube equipment. Save 66%--84% of the space; 8) Perfect protection circuit, high reliability; 9) Inside the power supply, there is no high voltage at the output end, and the safety is high. This equipment is widely used in welding, annealing, quenching, diathermy and other processes, covering automobiles, motorcycle parts, railway rails, aerospace, weapon manufacturing, machinery manufacturing, electrical manufacturing and special metal processing industries.
