The 3 phase power transformer step down is flame retardant, explosion proof, no pollution to the environment.Insulation materials such as glass fiber winding coil have self-extinguishing characteristics, which will not produce electric arc due to short circuit, and resin will not produce toxic and harmful gases under high heat.


Product Introduction

1)High reliability,advanced level of performance,reasonable economical indicators.

2)The core joints are of stepped shape with 3steps,and the surface of the core is coated with cured paint to lower losses and noise.

3)The winding has novel structure and its oil passage is reasonable designed.Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability.

4)The oil tank is various types,all have good outlook.

FAQ

1.What is the function of the input reactor?

The input reactor is used to limit the sudden change of the working voltage of the power grid and the current impact caused by the actual operating overvoltage, the spike single pulse included in the linear power supply operating voltage, or the operating voltage disadvantage caused by the commutation of the linear bridge rectifier circuit, reasonably Maintaining the frequency converter and improving the power factor, it can block the interference from the power grid, and can reduce the environmental pollution caused by the harmonic current caused by the rectifier module to the power grid.

2.What is the function of the power coordinating reactor?

In the remediation system software for reactive power compensation and harmonics, the power factor can be improved, and the filter function can be applied to the harmonics to suppress the waveform distortion of the power network operating voltage, thereby changing the quality of the power network and ensuring the optimal operation of the power engineering system.

3.What are the key functions of the output reactor?

It can restrain the output harmonic current, improve the output high frequency characteristic impedance, reasonably restrain dv/dt, reduce the leakage current of high frequency, maintain the frequency converter, reduce the noise of the machine and equipment.
