In order to limit the short-circuit current of the transmission line and protect the power equipment, a reactor must be installed. The reactor can reduce the short-circuit current and keep the voltage of the short-circuit system unchanged.
Read MoreThere are many types of power transformers, which can be classified into single-phase power transformers, three-phase power transformer, and multi-phase power transformers according to the number of power phases. It can be seen from the literal point that
Read MoreThe most common occurrence of transformer oil is the aging of transformer oil, which is often the case, so how to effectively suppress the aging of transformer oil?
Read MoreOil-immersed transformers can be divided into iron core transformers and iron shell transformers. If the winding is wrapped around the core, it is a core-type transformer; if the core is wrapped around the winding, it is an iron-shell transformer. The two
Read Moreoil-immersed transformers have lower cost than dry-type transformers.
Read MoreWhen 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

A transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power source is called the
Read MoreThe 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
