10Kv Oil Transformer

Distribution Transformer (10kV, 20kV) Oil-immersed Transformer Products structure and technical features Electricity is transferred to users from power stations through transmission and distribution system's voltage conversion. Firstly transferred via high voltage transmission lines, then lower the voltage in substations, lastly be fit to use. Distribution transformer locates closely to terminal users will lower voltage at a suitable level. Transformer , lower voltage at a level which is suitable for electrical equipments, is called distribution transformer, used in daily lighting and factory producing, low voltage is usually less than 0.4kv.In addition , distribution transformer's capacity is small, usually less than 3150kVA; and primary voltage is also low, at less than 35kV. Our distribution transformer adopt "CAD" design concept and its performance is accord with IEC60076,GB1094,GB/T6451.The core is manufactured with high quality cold rolled grain-oriented silicon steel, and steps overlapping structure is used for core manufacture, after overlapping, brush special hardener to make cores solid, thus to effectively reduce no-load loss and noise. The oil tank is corrugated structure, produced by our factory's oil tank automatic production line; surface pre-treatment solution and coated powder all use high-quality brand products; firstly be shot blasted, then spray powder, at last solidified in high temperature, so our oil tank has strong corrosion resistance. Winding is manufactured with high strength enameled wires(or paper covered wires),ampere-turns evenly distribute, insulation structure is reasonable, so winding's short circuit impedance is excellent. The body of distribution transformer adopts suspended structure, all sealing surface use quality acrylic rubber, can effectively prevent cold aging.

Furnace Transformer is a power equipment which is suppo- rting for EAF. It has more stringent requirements in electric, magnetic, thermal, mechanical and other aspects compared with other transformers, and has to comply with the operation process of various furnace transformers and load characteristics, so that it can meet users, and facilitate energy-saving emission reduction and other conditions. There are many kinds of furnace transformers. The company mainly produce the following products: High impedance furnace transformer, DC arc furnace transformer, ladle refining furnace transformer, submerged arc furnace transformer (including ferroalloy furnace tran- sformer, calcium carbide furnace transformer, yellow pho- sphorus furnace transformer,single phase titanim slag furnace transformer etc.), electro slag furnace transformer, frequency induction furnace transformer, single-phase graphite furnace transformer, etc. Take on-load tap furnace transformer with -shaped winding which is developed independently for example, the features as fellows: The transformer is a arc furnace power transformer which is used to make a high-quality steel and alloy smelting arc furnace. It consists of series voltage regulator transformer and main transformer which are mounted on the same tank. The two low-voltage winding are made of the , replacing the cumbersome welding process between two low-voltage windings. Features: 1.Wide range of voltage-regulate. Secondary voltage of differential voltage levels meets the arc furnace steel-making process requirements. 2.High-voltage has no restriction of switching insulation level, and it (e.g. 110kV) can be reduced to low-voltage directly, eliminating the intermediate substation and saving more than 30% invested. 3.Easy to choose suitable voltage-level load tap changer, economic and safe. 4.It can be accessed compensation capacitor in order to improve network power factor. 5.The main transformer works in constant flux density. Make full use of materials and have a good conservation. 6.Using the same reverse-phase parallel, electric (or magnetic) shielding, transposed conductors and so on to reduce losses and improve efficiency. 7.A separate voltage coil is used so that ampere-turn balance is good, coupled with cylinder pressure nail structure, its ability to withstand short-circuit is also increased and has high reliability. 8.Using third breaking off instead of primary breaking off so that it can be achieved with low price and high life of low-voltage circuit breakers instead of high price and low life of high-voltage circuit breaks. Take 31500/110 arc furnace transformer for example, the load loss, no-load loss, no-load current is dropped 13%, 17%, 26% compared with the original product respectively. It is a real energy-saving emission reduction innovative product. fumigation wooden package

Rectifier transformer is a transformer which used as the source of rectifier equipment. And primacy side of rectifier transformer connected with AC power is called line side, and secondary side connected with rectifier is called valve side. Our company use the advanced techniques and manufacturing process, and with domestic colleges and universities to develop a number of research projects. Using procedural design, insulation breakdown mechanism, the electric field numerical analysis and insulation technology, the impact of characteristics and anti-sudden short-circuit strength of winding, the loss of eddy current filed calculation are analyzed and calculated. With manufacturing experience on rectifier transformer for many years, our company has got major break-though on the basis of the traditional calculation, which will further improve the reliability and advancement of products. Features about rectifier transformer: 1.The rectifier transformer load is non-linear impedance, and valve side windings of rectifier transformer would get the currents which contain fundamental and other high-order harmonic superposition. And line side also gets corresponding non-sinusoidal currents connected by rectifier circuit coupling method. 2.According to different requirements of various customers, the valve side of rectifier transformer has a variety of special coupling method, such as: dual-back-star with inter phase reactor, three-phase bridge, star-delta parallel, six-phase bridge by inter phase reactor. 3.To improve power factor and reduce the line side harmonic currents of high-power rectifier equipments, rectifier transformer is needed to use star-delta winding phase displacement, phase-shift windings by phase displacement, autotransformer phase displacement, to improve the number of pulse of rectifier equipment. 4.According to the user¡¡¥s process requirements, the rectifier transformer line side voltage is required (such as 220kV) straight down to a very low valve side voltage (such as 1kV). The valve side voltage of rectifier transformer is required within a wide range of on-load tap from 5% - 105%. Auto voltage regulator and main theme of unity, string variable voltage regulator and other ways are used in rectifier transformer to achieve the purposes of a wide range voltage. 5.Self-saturable reactor can be used to change over and stabilize voltage in order to smooth rectify voltage. And some use silicon control to regulate voltage. 6.Valve side current of high-power rectifier equipment is very large, reaching 100kA and even greater. To improve power factor and avoid partial overheating and uneven distribution of current rectification components, it¡¡¥s required the technology of reverse-phase parallel. 7.With the wide application of AC frequency control technology, newly developed three-crack drive rectifier transformer came into being. And the lower voltage valve side of this transformer cracked into three independent branches, which can be made to supply for three different load power, which achieve ¡¡ã multi functional ¡¡À effect, reducing loss and saving area. 8.In order to reduce the large current in the fuel tank and other structures caused by loss, the rectifier transformer used magnetic shielding technology and so on. A number of 220kV and below and different kinds of rectifier transformers have been manufactured for the general industrial, electrochemical electrolysis, transmission, traction frequency, variable frequency power supply, DC power transmission and other industrial sectors over ten years, and got the user¡¡¥s high praise. Recently, the 220kV level on-load-tap rectifier transformers supporting the country¡¡¥s largest 600 thousand project of caustic soda is done, and got the high praise of users. fumigation wooden case
