Three-phase five collaboration in dry transformers

The dry transformer is one of the critical substations, based on the increased operating voltage of the working voltage or reduces the distribution application. Everyone see the material of the substation, the daily cleaning mention of the three-phase five-pillar, three-phase three-column structure, what does this also mean? Next, Xiaobian will introduce you.

Three-phase pillar-column shifter, said that the electromagnetic coils of the electromagnetic coil are assembled in three columns, which produces the "three-phase". The two columns next to them are their equivalent circuits. 

In addition to the above three-phase, there are three iron core columns, there are two sides of the iron core column that do not wind resistant, and the left and right of the five iron cores are connected to each other. In that, the zero-rade magnetic flux produced commodity circulation control loops according to the outer ferrous core column and left and right iron.

The low voltage electromagnetic coil of the substrate uses a copper chalet inductance, and the high-pressure coil uses an epoxy resin glue to cast or use a Nomex insulating material.

Substitute manufacturer, using three-phase five-column dry transformer, with some of the advantages:

Flame retardancy, explosion-proof type, no environmental pollution, high flame retardant level

Low noise, small body type, convenient installation, maintenance maintenance

Partial charge and discharge is small, the insulating layer is high, and the use of goods is long.

"Three defense" capacity is excellent, no cracking phenomenon
