Product Introduction

Three-phase copper oil-immersed distribution transformer 33kv is a common power equipment, widely used in distribution systems. The following is a detailed introduction to this transformer:

Basic parameters and characteristics
The main parameters of the three-phase copper oil-immersed distribution transformer 33kv include:

Voltage ratio: 33/0.4KV or 20/0.4KV
Power phase number: three-phase
Cooling method: oil-immersed self-cooling
Winding form: double winding
Core form: core type, the core shape is ladder type
Efficiency: 80%
 

Structural composition
The structure of the three-phase copper oil-immersed distribution transformer mainly includes the following parts:

Oil tank: used to hold transformer oil and other components, and plays a role in heat dissipation and insulation. The oil tank contains windings, cores and transformer oil. The structure of the oil tank varies according to the capacity and needs of the transformer, and may include heat pipe oil tanks, oil tanks with radiators, flat-top oil tanks, and corrugated oil tanks.

Winding: Responsible for the connection of the circuit, usually carefully wound with double-wire or enameled round wire.

Core: As the magnetic circuit part of the transformer, it is responsible for conducting the magnetic field.

High and low voltage bushings: Used to connect high and low voltage circuits
