What are the characteristics of all peralatan pemanasan induksi solid-state?

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) Most of the power rectifier and inverter circuit devices use module devices instead of single power devices. In order to achieve large power, series, parallel or series-parallel connection of power devices is used;

3) A large number of digital integrated circuits and special 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, application of power ferrite, etc.;

5) The frequency range is wide, from 0.1–400kHz covering the range of intermediate frequency, high frequency and super audio frequency;

6) High conversion efficiency and obvious energy saving. 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 has a compact structure, which can save 66%–84% of the space compared with the electronic tube equipment;

8) Perfect protection circuit and 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. Heat penetration before die forging, quenching and annealing of workpiece surface and local parts, brazing of motors, electrical appliances and valves, sintering of tungsten, molybdenum and copper-tungsten alloys, and melting of metals such as gold and silver.
