What should be considered when selecting and using bushings? When selecting and using bushings, certain considerations need to be taken into account. Bushings, as current-carrying components of transformers, directly impact the insulation performance of transformers. Here are the key points to be aware of during selection and usage: (1) Ambient Medium Temperature: For oil-immersed transformers, […]
How does the geological environment impact the operation of transformers? The primary consideration is the transformer’s ability to withstand earthquakes. Under normal operating conditions, it is stipulated that the horizontal acceleration of the ground should be less than 0.3g, and the vertical acceleration should be less than 0.15g. When installing transformers in seismically active zones,
What are the advantages of single-phase transformers? Less material usage: Single-phase transformers require 20% less iron and 10% less copper compared to three-phase transformers of the same capacity. Particularly when using a wound iron core structure, the no-load losses of the transformer can be reduced by more than 15%. This reduction in material usage leads
What kind of sealing material should be chosen for oil-immersed transformers? Choosing sealing materials that are compatible with the characteristics of transformers is crucial. Technical conditions related to sealing materials include the working medium, working pressure, and working temperature. The working medium mainly involves transformer oil, air, and water. The working pressure is primarily determined
Definition, Applications, Advantages, and Disadvantages of Split-core Transformers Split-core transformers, also known as split-core current transformers (CTs), are a type of transformer that consists of two separate parts that can be opened and closed for installation around a conductor. These transformers are commonly used in power monitoring and control applications to measure the current flowing
The Difference Between Phase Voltage and Line Voltage In an AC electrical system, voltage is an important factor to consider when designing and implementing electrical equipment. Two commonly used voltage measurements in AC systems are phase voltage and line voltage. Although they may seem similar, there are significant differences between them. Phase voltage refers to
How to Control Transformer Temperature Rise in High-Temperature Environments? —Synergistic Design of Heat-Resistant Insulation Materials and Forced Air Cooling Against the backdrop of global warming and increasing industrial demand, the stable operation of transformers in high-temperature environments has become a major challenge for the power industry. This article delves into a comprehensive solution for controlling
Comparison of the Four Core Partial Discharge Detection Technologies: In-Depth Analysis of Principles, Advantages, and Applications In the field of safety maintenance for high-voltage electrical equipment, Partial Discharge Detection (PD Detection) plays a critical role as an early warning system. As global power grids demand higher reliability for key assets such as transformers and reactors,
What should be taken into consideration during the assembly of transformer pressure plates? During the assembly of pressure plates, it is essential to simultaneously and evenly fasten the pressure pins on the pressure plates, and it is not allowed to tighten one side first and then the other. For structures with split pressure plates, ensure
How does coastal environment affect the operation of transformers? In coastal areas, the air contains salt spray, which impacts the creepage of bushings and leads to metal corrosion. To express the required leakage ratio for bushings, an equivalent salt density can be used, and the corresponding values are listed in the leakage ratio. Equivalent salt
