Special reactor for medium frequency furnace

Reactor is also called inductor. When a conductor is energized, it will generate a magnetic field in a certain spatial range it occupies. Therefore, all electrical conductors that can carry current are inductive in a general sense. However, the inductance of an energized long straight conductor is small and the magnetic field generated is not strong. Therefore, the actual reactor is a wire wound into a solenoid, which is called an air-core reactor; sometimes in order to make the solenoid have a greater inductance, An iron core is inserted into the solenoid, which is called an iron core reactor. Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductive reactants (inductors) and capacitive reactants (capacitors) are collectively called reactors. However, since inductors existed first in the past and were called reactors, so What people call capacitors now is capacitive reactors, and reactors specifically refer to inductors.

In order to adapt to different intermediate frequency furnace power supplies, special reactors for intermediate frequency furnaces are generally customized products. Customers need to indicate the operating frequency when purchasing (generally connected to a three-phase fully controlled rectifier back-end for smoothing, so the frequency is 300HZ, other countries use 60HZ power supply It is 360HZ). In addition, under special circumstances, you need to provide the back-end inverter operating frequency (generally, the higher the operating power of the power supply, the lower the frequency) and operating current (generally rectified DC current) to confirm the model.

Depending on the customer's working environment and usage, it can be divided into low-resistance type and high-resistance type. The low-resistance type is generally used in medium-frequency power supplies above 300KW, and with increased flow pipes and thicker copper pipes, it can better adapt to various different conditions. Medium frequency furnace heating power supply

With the development of technology, the iron core material is generally silicon steel sheet and has developed into a microcrystalline magnet. The size of the mid-frequency reactor has been greatly reduced, and the heat generation has been greatly reduced. However, its price is relatively high. It is generally used for mid-frequency IGBT power supplies. .

Therefore, in summary, dear customers, when ordering our company's medium frequency reactors, please follow the sales staff's requirements and provide as many detailed parameters as possible, so that our company can provide you with the most suitable medium frequency reactors for you. .
