Oil-immersed power transformer differential protection is designed and manufactured according to the principle of circulating current, and gas protection is designed and manufactured according to the characteristics that the internal fault of the transfor

No-load loss and load loss are important parameters of dry distribution transformers, but many people do not know the difference.

Transformer oil is an important part of oil-immersed transformers, which directly affects the performance of the entire transformer, so the quality of transformer oil is our concern. Today we explain the five factors that affect the electrical performance

After the American box-type substation is installed and used, there is basically no maintenance, but the products produced in China are indispensable for the maintenance of the box due to various reasons.
Due to the surface treatment technical problems o

Dry  power transformers are used in many industries, especially in industries such as construction and agricultural miners.
After the dry distribution transformer is rusted, it is necessary to carefully perform the descaling operation, and know how to ch

The container and sampling method used for sampling have the most direct impact on whether the actual quality of the oil can be truly reflected. The oil sample for the pressure test shall not be less than 0.5 kg, and the oil sample for the simplified test

In the event of an oil-immersed transformer failure, it is necessary to carefully observe and discover that some small faults of the oil-immersed distribution transformer can be solved. Today, I will teach you some repair techniques to help you operate oi

Not only the new residential area should be standardized, but also some existing old residential community oil-immersed transformer configuration methods should be analyzed. It is necessary to re-adjust the dry-type transformer configuration that can not

Although the transformers are now designed to be maintenance-free, some manufacturers have cut corners during manufacturing, causing short-circuits in oil-immersed distribution transformers. After the distribution transformer short-circuit fault, should i

The oil-immersed transformer must be carefully inspected before purchase to ensure the effect. However, many buyers do not understand oil-immersed distribution transformers, so ZTELEC teaches you how to judge the quality of oil-immersed transformers:

In order to ensure the normal operation of the oil-immersed distribution transformer, it is necessary to strengthen the operation and management of the distribution transformer, do a good job in the operation and maintenance of the transformer, analyze th

Nine major problems that must be paid attention to when installing power transformers

Note that the flux should be checked for saturation near the minimum input voltage and maximum pulse width. Since the pulse width is narrowed when the input voltage is high, the core is far from saturation. At transient loads, when the input voltage is hi

The epoxy paper substrate is a paper-based copper clad laminate using an epoxy resin as a binder. It is slightly better than FR-l in electrical and mechanical properties. Its main product model is FR-3, and the market is mostly in Europe.

Composite copper clad laminate, which mainly refers to CEM-1 and CEM-3 composite copper clad laminates.
