Discover key maintenance strategies for transformer equipment that can significantly extend its lifespan and optimize performance, ensuring operational efficiency and safety in industrial settings.Transformer equipment is the unsung hero of modern industry, silently enabling the efficient distribution of electrical power to drive our technological and industrial advancements. These unassuming devices play a pivotal role in managing voltage levels, ensuring the safe transmission of electricity to power our homes, businesses, and critical infrastructure. Yet, despite their critical role, transformers often operate in the background, out of sight and out of mind, until something goes wrong. In this comprehensive guide, we will shed light on the often-overlooked but immensely significant world of transformer equipment maintenance. We will explore how regular maintenance is not only vital but also transformative, capable of extending the lifespan of these workhorses and optimizing their performance. From manufacturing plants to utility substations, our journey begins with an exploration of the indispensable role of transformer equipment in industries and an understanding of why diligent maintenance is the cornerstone of their reliability and longevity.

Uncover the essentials of transformer cores and understand the important factors to consider when making your selection for optimal performance.Transformers stand as quiet sentinels in the realm of electrical systems, orchestrating the vital transfer and transformation of electrical energy that powers our modern world. These unassuming devices, often tucked away within substations or nestled within electronic equipment, form the backbone of electrical engineering, enabling the efficient distribution and utilization of electricity. Their role is fundamental, bridging the gap between power generation and practical consumption by stepping up voltage for long-distance transmission and stepping it down for safe use in our homes, industries, and devices. In essence, transformers are the uncelebrated architects of the electrified world we inhabit.Beneath the unpretentious surface of transformers lies a critical component—the transformer core. This unassuming core, far from passive, serves as the very engine that drives the conversion of electrical energy into magnetic energy and back into electrical energy while minimizing energy losses. It is the linchpin of transformer functionality, governing not only efficiency but also reliability. The selection of the right transformer core is paramount, as it directly shapes efficiency, longevity, and electromagnetic characteristics. In this article, we embark on a journey to unveil the profound significance of transformers and, most notably, their indispensable cores, equipping you with the knowledge necessary to make well-informed choices for the optimal performance of electrical systems.

In AC circuit, there are three concepts of electric power: active power, reactive power and apparent power. KVA stands for apparent power, which includes reactive power and active power. KW stands for active power, and kVar stands for reactive power. The relation between kW and kVar and conversion there is a concept - power factor cos ф, active power kW=UIcos ф, reactive power kVar=UIsin ф, and apparent power kVA=UI(U is voltage, I is current).

The winding and iron core of the transformer are the main components for transmitting and transforming electromagnetic energy, and ensuring their safe operation is a problem that people are concerned about. Statistics show that the fault is caused by the iron core problem, accounting for the third place in the total transformer accident. The manufacturing department has paid attention to the defects of the transformer core, and has made technical improvements in the metal hose and stainless steel hose grounding monitoring of the iron core and ensuring a little grounding.

With the development of the power system in the direction of energy saving and intelligence, the quality, reliability and performance requirements of power transmission and distribution and control equipment are gradually improved. In order to adapt and meet market demand, manufacturers of power transmission and distribution and control equipment continue to improve Product structure, improving product performance, and strengthening independent R&D and exploration of new technologies, new industries, new formats, and new models. Its development presents the following trends:

Transformer faults can be divided into internal faults and external faults.Transformer internal faults refer to the faults that occur in the transformer oil tank, including phase-to-phase short circuit of each winding, inter-turn short circuit of winding, short circuit fault between winding and iron core, single-phase grounding fault of single-phase winding or lead-out wire passing through the shell, winding disconnection fault, etc. Transformer external faults refer to various faults that occur on the external insulating bushing of the transformer oil tank and its lead-out wires, including single-phase grounding short-circuits and phase-to-phase short-circuits between lead-out wires caused by flashover or broken insulating bushings.
