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.
From June 19th to June 21th, 2018, ZTELEC Group will exhibit high quality insulation materials, transformers and enameled wires at CWIEME Berlin in Berlin, Germany. Welcome to our booth for business consultation.
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
On April 20th, the Russian customer arrived in Zhengzhou.
When the grid voltage is 20kv or 10kv, the transformer in this series can control the connection status between two windings on high voltage coil in each phase via conversion device
CWIEME Shanghai is the leading event for winding machine, insulation material, magnetic materials, electric motor and transformer manufacturing technologies.
Amorphous alloy transformer uses amorphous alloy as core, in which the metal atoms inside are arranged in disordered non-crystal sequence.It has lower loss than silicon steel materials, thus resulting in high effciency and energy saving.
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.
On 28th, December, Henan Zhongtian Aerospace Technology Group (ZTaero Group) held a big party to celebrate the Christmas Day and the coming New Year. All the company members attended the party, including our general manager Mr. Zhang and other leaders.
At present, the world economic development situation is tortuous and changeable. The developed countries are aiming at the high-end market in succession.
