Common problems of tap changer of power transformer

Tauranga .It can be seen from the above that from the perspective of power saving, transformers & ldquo; A small horse pulls a small car & rdquo; Can't compare with & ldquo; Middle car & rdquo;, Even less than & ldquo; Great Lars, little dragons & rdquo;, Therefore,Tauranga How to select power transformer, the loss of transformer full load and load must be considered in the calculation, and the results can be properly made in terms of power saving or power consumption. According to the correlation between the load rate and the transformer capacity: 3. The transformer load rate and power saving will be brought into the formula: the load index of the transformer, that is, the operating load and rated capacity of the transformer 1. Now it is illustrated by examples that both sides of the acadc al electron touch toe ground type seek the derivative of P, and then reduce the active power loss of the large capacity transformer from the active power loss of the small capacity transformer: that is, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuit

.Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below 0.2%,Tauranga Price of 800kVA distribution transformer, and then reduce the building structure noise transmitted by dry-type transformer oscillation.

Dry type transformer company

Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.

The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, 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.

The proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text, we have already mastered the structure and characteristics of dry-type transformer. In this part, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.

The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by 20%.

Bidding.When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, the winding of oil immersed transformer is generally divided into multiple modules, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module,Tauranga Working principle of power transformer, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.

Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management which can control the oscillation below 0.2%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.

High voltage fuse of transformer breaks one phase;

Analysis project.The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.

The transformer manufacturer will introduce the efficiency of the transformer to you

Manufacturing process and steps of dry-type transformer

Tauranga .Naturally, if the oil immersed transformer catches fire, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.

For example, in the 1970s, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ 4Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.

When the screw of the through core extruder holding the iron core of the transformer is loose, there are screw cap parts left on the iron core or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer, while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.
