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.

5Transformer manufacturers generally adopt IP protective casing, which can avoid the entry of solid dirt with a diameter of more than mm,power transformer price 1000kva rats,BrasiaOil immersed transformer manufacturerSelection of Value and Energy Conversion snakes, cats, birds and other animals, resulting in vicious common faults such as short-circuit fault and power failure, and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors, IP protective casing can be adopted, which can avoid being equally divided with the above IP protective effects However, so pay attention to the reduction of its operating volume.

kMasmehlenIn terms of the place of use, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; The engine oil is likely to spray out or leak after the fire,power transformer price 1000kva and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;

Then carry out the appearance inspection of the iron core, and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large, paint the damaged part.

The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, two pumps are started separately, and each pump is driven by kW motor, so the usual load is KW,power transformer price 1000kva CST = . One kva transformer was originally configured

fAfter tightening the loose bolts, seal the flange,BrasiaOil immersed transformer manufacturerSelection of Value and Energy Conversion so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.

AIn order to promote the use of energy-saving transformers, the Ministry of finance, the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the promotion and implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as , providing subsidies of - yuan / KVA for energy-saving transformers.

MsystemAfter the power transformer has been used for a long time, common faults of iron core will occur. Dont worry. Contact the transformer manufacturer and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:

kDTransformer manufacturers generally adopt IP protective casing, which can avoid the entry of solid dirt with a diameter of more than mm, rats, snakes,Power transformer price: 1000KVA, 33kV, 25kV, power transformer, oil immersed transformer, dry-type transformer factory cats, birds and other animals, resulting in vicious common faults such as short-circuit fault and power failure, IP protective casing can be adopted, which can avoid being equally divided with the above IP protective effects However IP casing will reduce the refrigeration capacity of the transformer, the ratio of output power to input power of transformer is called the efficiency of transformer so pay attention to the reduction of its operating volume.

At rated power, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.

Two point grounding device of iron core caused by residual welding scar;

Energy costsbThe appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by kW motor, so the usual load is KW, CST = . One kva transformer was originally configured

MIn specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

Visual inspection method for transformer inspection

qMasmehlenIt is understood that in China, transformers have experienced the whole process of replacing many series products such as S. As early as the middle and late s, S Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb- and jb - Specifications operating in the power network at that time. Since the th century, urban power grids have been transformed all over the country, and S series distribution transformers have been used to replace S Series. In recent years, S and S commodities are gradually selected in large quantities in the transformation of urban and rural power networks in China, and their full load loss is % - % less than that of S transformer.

yLTransformer 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.

How is the quality level of dry-type transformer compared with foreign countries?
