Product Description

For many years, the company has used high-quality materials and advanced technology to produce 1kva-2000kva, SG series of three-phase isolation transformer, products in line with VDE0550, IEC 439, JB5555, GB5226 International, national standards. OSG series three-phase isolation transformers are widely used in AC 50/60HZ, input and output voltages not exceeding 1000V for various power supply occasions. Product input, output, voltage level, connection group, adjust the tap position, winding capacity distribution, secondary winding with or without shell, etc. , according to the user's requirements for careful design and manufacturing. The utility model has the advantages of fire-proof, moisture-proof, safe and reliable, energy-saving, convenient maintenance, etc. .
Features:
Isolation Transformer is to set up a new center line-earthing can eliminate the common-mode interference and other Central lines in the power network, isolation transformer will be three wire △ wiring into four wire Yo system, shielding further eliminates high-frequency pulse interference and noise coupled within the transformer, although shielding the isolation transformer to a variety of N-G interference (pulse and high-frequency noise) can be effectively prevented, but the transformer must be properly grounded, very strict, otherwise anti-common-mode interference will be ineffective.

Connect the isolation transformer (triangle/Star) at the power input

1. If the third harmonic and interference signal is serious, using △/Yo isolating transformer can remove the third harmonic and reduce the interference signal.

2. The △/Yo isolating transformer can be used to produce new neutral line, so that the equipment is independent of the neutral line of the power grid, and the abnormal operation of the equipment caused by the bad neutral line of the power grid can be avoided.

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

Connect the isolation transformer (star/triangle) at the output end of the power supply

1, to prevent the current distortion of nonlinear load, affect the normal work of the power supply and back to the grid, play a role in purifying the grid.

2. The distortion of non-linear load current affects the accuracy of sampling. It can be sampled at the input of Yo/△ isolating transformer to get the control signal which can reflect the actual situation, so that the regulated power supply can be controlled normally.

3, if the load is not balanced, the use of Yo/△ does not affect the normal work of the regulated power supply.
