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.

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?

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?

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.

Insulation detection cycle of dry type transformer 2020-04-15

Dry type transformer has certain insulation. The insulation performance of dry type transformer is one of the important properties of dry type transformer. The insulation performance of dry type transformer is to be tested, but it is also necessary to pay attention to the relevant cycle when testing. What is the specific inspection cycle? Or do you want to know more about the Xiaobian of the dry type transformer factory?

Dry type transformer winding 2020-04-09

Background technology the existing dry type transformers commonly used in the domestic market are generally cast type dry-type transformers. Because the winding of the transformer is wrapped in epoxy resin, the heat dissipation condition of the winding is greatly restricted. The expansion coefficient of copper conductor and epoxy resin is different in the process of cold and hot change, and the epoxy resin will be used after long term use.

High voltage coil of dry type transformer 2020-04-09

At present, the temperature rise of the high voltage coil of the general dry type transformer is usually determined by the insulation level of the product, and the temperature rise is also related to the heat output and the heat dissipation area of the coil. The temperature rise of the high pressure ring of the dry type transformer is related to the service life of the high voltage coil of the dry type transformer. The purpose of the utility model is to provide a transformer which can reduce the height of the transformer.

Short circuit winding of dry type transformer 2020-03-30

The short circuit of dry type transformer is a normal phenomenon. There are many factors that affect the short-circuit of dry type transformer. One of the more common parts is the inter turn short circuit of dry type transformer. How should we solve the problem of interturn short-circuit in dry type transformers?

Starting temperature of dry type transformer fan 2020-03-23

Dry type transformer is an important type of transformer. Dry type transformer's fan is an important equipment for dry type transformer, and the fan of dry type transformer is also working continuously. The main temperature rise of the fan of dry type transformer is also more important. How does the temperature rise of the fan of the dry type transformer rise? Or is it a dry type transformer?

Analysis and introduction of dry type transformer 2020-03-20

A temperature display controller is set up on the epoxy resin dry type transformer to display and control the running temperature of the dry type transformer winding, so as to ensure the normal service life of the dry type transformer. The temperature sensor PT 100 platinum resistor is inserted into the low voltage winding. After obtaining the temperature signal, the circuit is processed and the cycle is displayed on the control panel. Temperature setting, fan manual /...

No-load temperature of dry type transformer 2020-03-16

The temperature of dry type transformer is constantly changing. The temperature determines the operation of dry type transformer. The type of dry type transformer is quite different. Today we mainly explain to you that the no-load temperature of dry type transformer. What is the main standard of the dry load of the dry type transformer?

Winding structure of dry type transformer 2020-03-05

The winding is the basic unit of dry type transformer, and the winding of dry type transformer can improve the transportation of voltage and current inside the dry type transformer. The winding structure of dry type transformer is rather complicated. When dry-type transformer is disassembled, a lot of winding of dry type transformer will be seen, the structure of winding of common dry type transformer and dry type transformer.
