Product Description

A 33kv 35kv 2000 kva oil immersed power transformer is a power equipment in which the core and windings are fully submerged in insulating oil. The oil serves multiple purposes, which includes electrical insulation, heat dissipation, and component protection. The operating principle is based on electromagnetic induction. When alternating current is applied to the primary winding, an alternating magnetic flux is generated within the core. This changing magnetic field induces a voltage in the secondary winding. It enables the transfer and conversion of electrical energy.

The insulating oil plays a vital role throughout this process. It electrically isolates energized components while simultaneously removing the heat generated during operation. Thanks to these characteristics, A 33kv 35kv 2000 kva oil immersed power transformers are widely used in power generation plants, substations, industrial distribution networks, and other applications that require reliable high voltage and high capacity power transmission.

Structure and Operating Principle:

A 33kv 35kv 2000 kva oil immersed power transformer consists of several key components,of which the transformer includes the magnetic core, windings, oil tank, conservator, bushings, tap changer, and gas relay.

Based on structural design,33kv 35kv 2000 kva oil immersed power transformers are generally divided into two categories. The first is the core type transformer, in which the windings surround the magnetic core. This design is the most commonly used in modern power systems. The second is the shell type transformer, where the magnetic core surrounds the windings and is typically used in specialized applications.

Each component is applied an important function. The oil tank stores the insulating oil and shall provide excellent sealing performance. The conservator not only accommodates changes in oil volume caused by temperature variations, but also helps maintain a stable oil level. Bushings allow electrical conductors to pass through the 33kv 35kv 2000 kva oil immersed power transformer enclosure while maintaining safe insulation between energized conductors and grounded metal parts.

The insulating and cooling functions of transformer oil are achieved through its physical properties. Its high dielectric strength provides effective electrical insulation between live components. At the same time, its low viscosity allows smooth circulation throughout the oil immersed transformer,which enables efficient heat transfer. During operation, the oil flows around the windings and core,to absorb heat and to carry it to radiators.Additionally,The heat is then released into the surrounding environment through natural air cooling or enhanced cooling systems when required.
