What is the working principle of resin cast three-phase dry-type distribution transformer？
Definitions and Characteristics：
6.3kV: It indicates that the voltage on the high-voltage side of the transformer is 6.3 kV.
Resin Casting: It means that the coils of the transformer are cast with epoxy resin or other synthetic resins to form a solid whole, which has excellent insulation properties and mechanical strength.
Three-Phase: It means that the transformer has three independent windings and is applicable to three-phase alternating current systems.
Dry-Type: It refers to the fact that the transformer does not use a liquid cooling medium (such as transformer oil), and usually adopts natural air cooling or forced air cooling.
Working Principle：
Input Voltage: The high-voltage power source of 6.3 kV is applied to the transformer through the primary winding.
Generating Magnetic Field: The current in the primary winding generates an alternating magnetic field in the iron core.
Transferring Magnetic Field: The alternating magnetic field is transferred to the secondary winding through the iron core.
Inducing Electromotive Force: The alternating magnetic field induces an electromotive force in the secondary winding, generating a low-voltage output voltage.
Output Voltage: The secondary winding outputs the required low-voltage electrical energy for the load to use.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
