What is the difference between dry-type transformer and oil-immersed power transformer? How to choose between the two?
Details of the structure, cooling mode, installation and commissioning of dry-type transformers
2021-10-23
Dry-type transformer refers to the core and winding is not immersed dry-type transformer refers to the core and winding is not immersed in the coil and core cast together, and the use of natural cooling or air cooling of a power transformer. As a post-rise power transformation and distribution equipment, it has been widely used in power transmission and transformation systems in factory workshops, high-rise buildings, commercial centers, airports, docks, subways, oil platforms and other places, and can form a complete set of substations with compact structures together with switchgear. At present, China's dry-type power transformers are mostly three-phase solid forming SC series, such as: SCB9 series three-phase winding transformer, SCB10 series three-phase foil transformer SCB9 series three-phase foil transformer. Its voltage level is generally in the range of 6-35KV, and the maximum capacity can reach 25MVA. For dry-type transformers, do you want to know more? The following is a detailed introduction to the structure of dry-type transformers, cooling methods, types, and oil-immersed transformers have what advantages? Installation and commissioning, how to judge the fault from the sound, the noise caused by the external structure and the solution, the selection points. take a look at it!

Distribution transformer fault analysis and treatment of one of the lectures.
2021-03-18
Distribution transformer, referred to as "distribution transformer". Refers to a static electrical appliance in a power distribution system that transforms AC voltage and current according to the law of electromagnetic induction to transmit AC power. In some areas, power transformers with voltage levels below 35 kV (mostly 10KV and below) are called "distribution transformers", referred to as "distribution transformers". The place and place where the "distribution transformer" is installed is both a substation.

The most common fault analysis of transformer
2020-08-28
Power transformer is a kind of static power equipment that changes the size of AC voltage, and is one of the core equipment in the power system. In the process of power transmission and distribution, power transformer is the core of energy conversion and transmission, and is the only way for the national economy to source energy from all walks of life and thousands of households. If the transformer fails, it will affect the safe and stable operation of the power system, which is very important equipment in the power system. Once an accident occurs, it will cause great economic losses. Analyze all kinds of power transformer accidents, find out the causes, summarize the methods of handling accidents, control the accident loss in the minimum range, and minimize the damage to the system.
