Transformer is a kind of power engineering equipment that converts working voltage and current according to the basic law of magnetic effect of current. In the whole process of power transmission and transformation of power engineering, it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss in the whole process of electromagnetic energy transmission. Therefore, the power consumption of the processing plant is all connected with kV switching power supply, the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.

xVaregumThe oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.

Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy,Product display but consuming electromagnetic energy.

Ucancun This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.

WgTransformer is a kind of power engineering equipment that converts working voltage and current according to the basic law of magnetic effect of current. In the whole process of power transmission and transformation of power engineering,WilwardOil immersed transformer manufacturerIndustry development relationship it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss in the whole process of electromagnetic energy transmission. Therefore, the power consumption of the processing plant is all connected with kV switching power supply, which is converted into bottom voltage electromagnetic energy through transformer.

With Vietnam and Malaysia Chinas first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world, occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.

This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.

l& ldquo; YN, D & rdquo;, in which indicates that when the working voltage phasor of the primary side line, as the minute hand,Product display refers to the position at oclock, the phase voltage phasor of the secondary side is at oclock. That is, the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).

DIn fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.

LmarketTransformer is a kind of power engineering equipment that converts working voltage and current according to the basic law of magnetic effect of current. In the whole process of power transmission and transformation of power engineering, it is necessary to carry out voltage transformation and blood pressure reduction according to the transformer to reduce the loss in the whole process of electromagnetic energy transmission. Therefore, the power consumption of the processing plant is all connected with kV switching power supply, which is converted into bottom voltage electromagnetic energy through transformer.

lDOil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.

For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition,Product display the oil with the same basic same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than %, there is generally no problem. However,WilwardOil immersed transformer manufacturerIndustry development relationship if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.

Dry type transformer is a common electrical equipment, such as variable frequency power supply.

Test methodoTransformer manufacturers said that at this stage, the energy-saving distribution transformer Market in China is relatively scattered, coupled with the constraints of factors such as low threshold in the field, uneven companies, lack of evaluation and specifications,Power transformer price: 1000KVA, 33kV, 25kV, power transformer, oil immersed transformer, dry-type transformer factory and inadequate technical innovation, resulting in the slow marketing and promotion of energy-saving transformers.

VOn load commissioning:

When the operating oil is mixed with different types of new oil or used for oil, in addition to the accurate measurement of the cold filter point of the mixed oil, and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor so it can be managed and used in a mixed manner.

zVaregumHow to select dry-type transformer

vIPower transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.

The insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;
