Single Phase Isolation Transformer Manufacturer

The function of isolation voltage transformer:

The main function of isolation transformer is make primary side and the secondary side of the electrical insulation completely, also make the circuit isolation. In addition, the advantage of the characteristics of its core big loss at high frequency, thus suppressing high frequency noise is introduced into the control loop. With isolation transformer secondary to suspend, can only be used in small power range, shorter lines. At this point, the system of capacitance current is small enough to harm the person. There is also a very important role is to protect personal safety! Isolation dangerous voltage.

 

The nature of isolation transformer:

Isolation transformer belongs to the safe power supply, are commonly used to machine maintenance, have the effect of protection, lightning protection and filtering. Isolation transformer primary side and the vice side voltage can be made according to the customer's requirements. The output and input terminal of isolation transformer is completely "open circuit" isolation, thus it can take effect to the input end of the transformer voltage of power supply (power supply) for a good filtering effectively. And also supply pure and safe power to electrical equipment.

 

Features of our isolation transformer:

To connect the isolation transformer to the power input terminal:

   1.1 If the three harmonic and interference signal are serious, using △/Yo isolation transformer, the three harmonic and the disturbance signal can be removed and reduce.(△/Yo means input with null wire, output without null wire)

   1.2 △/Yo Isolation transformer can be used to create new neutral line, the device has nothing to do with power grid neutral, so that can avoid the abnormal running of machine which caused by the bad grid neutral line.

   1.3 Current waveform distortion caused by nonlinear load (such as three harmonics) can be isolated and not pollute the power grid.

To connect the isolation transformer to the power output terminal:

   2.1 To prevent the nonlinear load current distortion which may affect the normal work of the stabilized voltage supply and reverse back to the grid, it also has the effect of purification power grid.(Yo/△ means input without null line, output with null line)

   2.2 Nonlinear load current distortion will affect the accuracy of sampling, we can sampling in the input of Yo/△ isolation transformer, so that we can get the actual status of the reaction control signal, it makes the control of regulated power supply be normal.

   2.3 If the load is imbalance, to use Yo/△ isolation voltage transformer will not affect the normal work of the regulated power supply.

 

Advantages of our transformer:

1. Low loss, high efficiency, the internal core of the transformer made by the high quality silicon steel sheet and high temperature resistant glass silk covered wire.

2. Long using life: using class H insulation, internal insulation heat coefficient is extremely high, normal life is around 20 years.

3. The transformer is designed scientific and reasonable, low voltage regulation, can be used for a long time.

4. Beautiful out looking, with sliding interlock castor which is easy to move and install; at the same time our transformer equipped with high quality large axial flow fan, and provide reasonable vents, easy to heat dissipation; Light box body, small volume, light weight, easy to ensconce.

5. The panel voltmeter showing data is accurate which is easy to see.
