Induction Heating Transformer

Product Detail

If you are looking for high quality customized induction heating transformer, please feel free to contact with us by Send Inqury, which is one of the leading induction hardening transformer manufacturers in China.

Induction heating transformer

Application range of induction heating transformer

The multi turn ratio induction heating transformer (hereinafter referred to as transformer) is mainly used for the induction heating of medium frequency, supersonic frequency and high frequency and induction heating of elbow pipe, welding, hot rolling diathermy and so on, which can reduce the voltage for the induction heating, and the isolation and impedance are matched to each other.

Characteristics

The transformer has potting and non potting types. According to the different usage and frequency of the transformer, the magnetic circuit can adopt silicon steel iron core, amorphous alloy, ferrite and so on. The transformer winding coil adopts water cooling system, and the coil adopts overlapping structure. In order to meet the different requirements of customers, the primary and secondary transformer can combine different turn ratio.

Working conditions

1?It needs water for cooling, the pressure of the cooling water needs to be 0.4MPa-0.6MPa, and there shall be no sundry in the water.

The cooling water needs to meet the following requirements:

PH value:                 7-8.5

      Suspended solid:          <10mg/L

      Basicity                   <60mg/L

      Chloridion          average<60mg/L,maximum<220mg/L

     Sulphate ion:                <100mg/L

       Iron ion:                   <2mg/L

     Solubility si02:               <6mg/L

     Solubility solid:               <300mg/L

     Electric conductivity:          <500us/cm

 Hardness:     charged body   <10Ca0mg  equivalent

                  uncharged body  <60Ca0mg  equivalent

2?When the transformer is working, constant water supply shall be guaranteed, the inlet temperature of the water shall be no more than 35?, and the outlet temperature shall be no more than 60?.

Electrical connection of transformer

When the transformer is delivered to customers, there shall be enough connection straps, and the transformer turn ratio adjustment diagram shall be provided so that users can connect the turn ratio according to it. 

Water circuit connection of transformer

Transformer is delivered to customers with detailed water circuit connection diagram. The water inlet and outlet of the whole series transformers adopt fast-changing coupler, which is convenient to change transformer.

If customer needs, our company can provide transformers with temperature and flow protection.

Parameters and demands for customized transformer

 1?Power of heating power supply matched with transformer, maximum power for normal work.

 2?Frequency of heating power supply matched with transformer, maximum frequency range for normal work.

 3?Form of the output waveform of the power supply

 4?Ratio of maximum and minimum power

 5?Transformer load rate, 100% load rate, power startup without stopping, working time(s), stopping time(s)

 6?Whether the water separator is provided with the transformer

Transformer customized

According to the users requirement, we can produce many kinds of special hardening transformer, isolation transformer, boosting transformer.

Maintenance of transformer

The common faults of the transformer include: 1) Short circuit caused by coils isolation breakdown. 2) Coil burn-out because of cooling water shortage, which is caused by poor water quality or high temperature of input water. 3) Damage due to bad contact, such as the connection strap is too tight or too loose. 4) Damage due to serious heat caused by bad contact, which is because there are too much oxide on the surface of the transformer secondary connection plate. 5) Damage of transformer magnetic circuit caused by improper frequency when users use the transformer. We can install flow protection switch and temperature protection switch or sensors to protect the transformer. When the transformer is in use, we shall usually check the water quality, and replace the water which has become bad in time, if the pipeline has incrustation scale, it shall be cleaned in time and supplied with qualified cooling water. When checking the transformer, we shall pay attention that whether the temperature of the transformer turn ratio connecting piece and the transformer secondary output stage plate is too high and we shall carry out a real-time processing..

Since the traditional induction heating transformer can not meet the requirements of current customers, in order to meet customer' requests for quality stability, reliability, and uniformity of the quenched products, interchangeability of transformer replacement, and repeatability after replacement, our company introduces many series induction heating transformers to meet the needs of customers for high-end induction heating transformer.
