How to reduce the failure of dry-type transformer?
Rosario.The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core, its orientation and size change with the change, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.
Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.
.The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling date,RosarioHow much is a dry-type 1250 transformer, sampling person, weather conditions and other materials of the oil sample.

The dry-type transformer is composed of two winding resistances, resulting in four wiring groups: & ldquo; y, Y & rdquo;, & ldquo; D, Y & rdquo;, & ldquo; y, D & rdquo; and & ldquo; D, D & rdquo;. In China, only & ldquo; y, Y & rdquo; and & ldquo; y, D & rdquo; are selected. Because there are also two types of Y-connection with neutral line and without neutral line. If there is no neutral line, it will not be upgraded. All marks show that with neutral line, it will not be upgraded The letter N after the English letter Y indicates that the neutral line has transformer grounding wire. Yn0 wiring group, the minute hand points to 12. & ldquo; 12 & rdquo; in the new wiring group it is indicated by & ldquo; 0 & rdquo.
The step-up dry-type transformer refers to the instantaneous operation of voltage. At this stage, there are few manufacturers of dry-type transformer that can reasonably guarantee the instantaneous step-up in China. The step-up dry-type transformer has strong step-up capacity and good practical effect. The difference depends on that the transformer power switch without excitation regulator does not have the ability to change gear with load. Because this kind of tap power switch can cut off the whole process in a short time during the whole process of gear change, so the dry-type transformer shall be powered off during regulation. Therefore, it is generally used as a dry-type transformer that is not very strict in voltage regulation and does not need to be adjusted frequently.

Quality recommendation.When we apply oil immersed transformer we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
On load commissioning:
The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance,RosarioProduction technology of oil immersed transformer,RosarioDry type transformer production video, capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation, the good model is the solid model of infinite transformer core column, but there are many calculation methods.
High quality and low price.The noise of dry-type transformer comes from
Step up process of dry-type transformer?
With the rapid development of society and the continuous development trend of computers, the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed, the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected, Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage, but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.
Rosario.When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.
The conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.
The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
