When the dry power transformer is in normal operation, the core must have a reliable grounding. If there is no grounding, the suspension voltage of the core to the ground will cause the core to intermittently break through the discharge, and the core is g
Read MoreOil-immersed power transformer differential protection is designed and manufactured according to the principle of circulating current, and gas protection is designed and manufactured according to the characteristics that the internal fault of the transfor
Read MoreNo-load loss and load loss are important parameters of dry distribution transformers, but many people do not know the difference.
Read MoreDry power transformers are used in many industries, especially in industries such as construction and agricultural miners.
After the dry distribution transformer is rusted, it is necessary to carefully perform the descaling operation, and know how to ch
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,
Read MoreThere 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
