Three-phase Isolation Transformer Introduction:

Three-phase Dry Type Isolation Transformer is a new generation of energy-saving power transformers developed by our factory from 300VA to 1600KVA on the basis of similar international products and in accordance with international and national standards such as IEC439 and GB5226. The winding adopts hole array winding. Vacuum impregnation is adopted for the transformer to make the insulation level of the transformer reach F or H, and the product performance reaches the advanced level at home and abroad. SG series three-phase dry-type isolation transformers are widely used in circuits with AC 50Hz to 60Hz and voltage lower than 2000V. Including single to three-phase and two to three-phase transformers， All these can be customized according to the different requirements of the end user.

Instrument for isolating transformer

The dry-type isolation transformer is widely used in circuits with AC 50Hz to 60Hz and voltage below 660V. Tongrun Photoelectron's products can be custom-designed based on user requirements, including input and output voltages, connection configurations, the number and location of tap-changing devices (generally ±5%), the distribution of winding capacities, the configuration of secondary single-phase windings, the use of rectifier circuits, and whether a case is required. The company carefully tailors its products to meet specific needs.

Application of regulated power supply

One 、 Connect the isolation transformer (delta/star) at the power input end

1. If the third harmonic and interference signal of the power grid are relatively serious, △/Yo isolation transformer can be used to remove the third harmonic and reduce the interference signal.

2. △/Yo isolation transformer can be used to generate a new neutral line so that the equipment has nothing to do with the neutral line of the power grid to avoid the abnormal operation of the equipment due to the poor neutral line of the power grid.

3. The current waveform distortion caused by nonlinear load (such as the third harmonic) can be isolated without polluting the power grid.

Two 、 Connect the isolation transformer (star/delta) at the power output end

1. In order to prevent the current distortion of nonlinear loads from affecting the normal operation of the regulated power supply and returning it to the grid, measures to clean the grid need to be taken;

2. The distortion of nonlinear load current affects the accuracy of sampling. You can sample at the input end of the Yo/△ isolation transformer to obtain control signals that can reflect the actual situation so that the stabilized voltage power supply can be controlled normally;

3. If the load is unbalanced, the use of Yo/△ will not affect the normal operation of the regulated power supply
