How to distinguish three common insulation materials DMD, NHN, DMDM, what are the differences between the three
Epoxy tube is made of electroless E-glass fiber cloth impregnated with epoxy resin, after baking, forming the mold after hot pressing processed round cross-section of the rod of the glass cloth rod, with high mechanical properties.
Will introduce to you the transformer in the mobile phone, and how good transformer in the mobile phone is to ensure everyone's safety
Introduce the important role of the oil pillow above the oil-immersed transformer for the transformer
Laminated wood has the characteristics of good insulation properties, high mechanical strength, and easy machining.
To introduce to you the development of Chinese transformers in recent years
Multiple on-load tap-changer transformers are grouped together for parallel operation. As long as one of them fails, it will affect the normal operation of the entire system.
After the operation of the transformer has four operating states
Correct operation of the transformer helps to extend the life of the transformer
This article mainly introduces oil-immersed pressure swing precautions.
The magnetic saturation transient effect of transformer should pay attention to whether the flux is near saturation under the condition of minimum input voltage and maximum pulse width. Because the pulse width will narrow when the input voltage is high,
There are many reasons for transformer internal faults and accidents due to transformer outlet short circuit, and they are also more complicated. It is related to structural design, raw material quality, process level, operating conditions and other facto
The waveforms of this section are certainly classical interference waveforms, random interference, at the beginning of the voltage opening, and the test voltage is not synchronized with the Zhou Bo of the power supply, and the interference pulse is direct
Dry transformer has more advantages than oil immersed transformer.
At present, the world economic development situation is tortuous and changeable. The developed countries are aiming at the high-end market in succession.
