How to choose dry type transformer 2020-06-06

Dry-type transformers are commonly used devices for converting high voltage directly from power stations to low voltage. Therefore, it is safe and effective to use low-voltage machinery and equipment that can be processed in offices, transportation centers, schools and factories, so as to save energy. Through this process, dry transformers generate large amounts of heat, which must be expelled to maintain safe operation.

Cause of winding damage of dry type transformer 2020-06-06

Poor manufacturing process: winding of dry type transformer has uneven winding, winding number accumulation, insulation short circuit or damage between layers, winding monotonicity, winding structure strength, insulation short circuit and so on. The short circuit between the winding is caused by the location change of main transformer winding. The risks of winding include insulation operation, poor welding and burrs. The plan was inappropriate.

Alarm temperature of dry type transformer 2020-06-01

The dry type transformer has a certain temperature. If the temperature of the dry type transformer exceeds a certain period and time, the dry type transformer will automatically alarm. The temperature of dry type transformer alarm is directly related to the running time and efficiency of dry type transformer. So how does the alarm temperature of dry type transformer be specified? Or dry type?

Trip temperature of dry type transformer 2020-06-01

There are various kinds of protection inside the dry type transformer. The temperature inside the dry type transformer is one of the important ways to protect the dry type transformer. When the internal temperature of dry type transformer reaches the limit or reaches a certain degree, all kinds of trip will appear in dry type transformer to protect the circuit. What is the temperature of dry type transformer?

Video of dry type transformer assembly 2020-06-01

Dry-type transformers can be customized now. The size of dry transformers and many parts can be assembled as if they were the same as computers. There are many problems to be noticed in the assembling process of dry type transformers. Usually, there are also some technical requirements. So for dry type transformer assembly technology related...

What are the problems of dry type transformer industry in 2020? 2020-05-31

Dry type transformer manufacturing industry is closely related to people's production, manufacture and life. Dry type transformer manufacturing is developing. In the course of the overall development trend, the reform of manufacturing and technology comprehensive reform continues. Many companies are emerging, most of which are small and medium-sized enterprises. The independent innovation ability of manufacturing industry is insufficient. In the development trend,

How can dry transformers improve efficiency? 2020-05-31

Dry type transformers are applicable to various fields, and have relatively large functions in production, manufacture and use. Dry type transformers are used for continuous operation. High efficiency, can help people's economic and social development, production and production projects. In fact, people want to improve the efficiency of dry-type transformers, so how to improve efficiency?

Normal temperature of dry type transformer 2020-05-31

Dry type transformer is an important industry of transformer. In order to improve the performance of dry-type transformers, dry type transformers have many problems in production. More attention should be paid to the fixed production and the tightening of dry type transformers. It is important to improve the level of technical management after fully recognizing the technical management of the modified transformer after confirming the protection state of the dry-type transformer.

How to adjust the tap changer of dry type transformer 2020-05-11

Under the condition of dry transformer operation (load), by adjusting the position of the tap switch, the connection position of the dry type transformer is changed, and the output voltage of the dry type transformer is adjusted. Operate switch controller to adjust. Manual operation to check whether the driving mechanism is flexible. Confirm the interlocking switch, limit switch and sequence switch in the power box.

What is the key to dry type transformer operation? 2020-05-08

The key to the operation of dry type transformers is the protection and safe operation of dry-type transformers. The safety protection of dry type transformers requires the joint protection of engineers and operators. How to effectively protect dry transformer? Internal and external fault of dry transformer fault. Internal fault refers to all kinds of faults in the oil tank of dry type transformer, mainly through gas and differential protection.

Development history of dry type transformers 2020-05-08

In recent years, with the development of urban construction, electric dry-type transformers are located in buildings, low level railways, airports and other places where fire requirements are high. In order to meet the fire requirements, there is no oil dry transformer. The working parts of windings and cores of early dry-type transformers are exposed to air. In order to solve the dry-type transformer winding fiber insulation materials due to moisture absorption.

What are the energy saving measures for dry type transformers? 2020-05-08

There are 4 energy saving measures for dry type transformers. Reduce no-load loss, reduce load loss, reduce other parts, and reduce the loss by using the working characteristics of machine tools. 1, reduce no-load loss (1) use good performance silicon steel plate or amorphous alloy sheet, ladder connection. (2) improve the core structure and technology, reduce the process coefficient. ...
