 Description

 

The application of the 400MVA/230kV power transformer can significantly improve the economy of the UHV substation, and matches well with the transmission capacity of UHV lines, which has wide prospect of application. Because of its large capacity and large volume, the whole transportation weight with nitrogen is about 470-490 tons, and due to the restricted transport conditions, the transportation becomes the critical issue for application of 400MVA/230kV power transformer. In order to make the products applicable to any UHV substation in our country, the state grid of corporation of China set the "A study of easy-transport large capacity UHV Transformer” as a key scientific research projects, and entrusted BTW to carry out the research.

During the process of research and development, BTW adopted the advanced design technology and modular design, the transformer can be transported disassembly and with advantages of compact core and winding body, less transportation weight and low transportation cost, effectively solves the need of UHV construction in the transportation restricted areas. By using the most advanced 3D magnetic field calculation software, BTW performed detailed analysis and calculation for the magnetic flux leakage and eddy current loss of the transformer coil, iron core and oil tank steel structures. Besides, by using of the advanced electric field calculation software, BTW performed detailed analysis and calculation of main longitudinal insulation, and mastered the arrangement of the main longitudinal insulation of large capacity UHV transformer and the control of distribution of winding magnetic flux leakage. All of which make the products with low loss, low noise, small volume, strong anti short circuit ability, no local overheating and other significant advantages, and guarantee the long-term safe and stable operation.

The world's first on-site assembled large capacity UHV Transformer’s right at the first time once again filled the gap in the field of UHV transformer research after Chinese transformer industry overcame the difficulty of integral transport of  the 400MVA/230kV power transformer, which marks BTW has fully occupied the world transformer industry technical peak. The successful development of the product filled the gaps in the domestic technology and met the urgent need of UHV construction application in our country, greatly improved the technical level and manufacturing ability of BTW in terms of UHV Transformer products.

Q:Is the LTC transformer a regulated voltage transformer?
Is a voltage regulator. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:What are the specifications of the transformer capacity?
The optimum load rate of the transformer (ie, the load rate at the highest efficiency) is not in the rated state, but between 40% and 70%. The load factor is too high and the loss increases obviously. On the other hand, Margin is small, a slight increase in load, you need to replace the large capacity box change, frequent capacity is bound to increase investment, affecting power supply.
Q:Three-phase three-winding transformer high-pressure medium-pressure low pressure is what it means
transformer: Transformer is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:Which is good for the transformer?
JMBBZBJZ line lighting transformer, JBK machine control Transformer, SSG Servo Transformer, Low Voltage High Current Heating Transformer, SBW High Power Compensated Power Regulator, SBW-F Splitter Regulator, SVC High Precision Fully Automatic AC Voltage Regulator, Precision Clean Regulator, Microcomputer No Touch Point voltage regulator, UPS, EPS power supply, KSG mine transformers, DN resistance welding water-cooled transformers, reactors, contact-type automatic voltage regulator, column high-power electric voltage regulator,
Q:Is the transformer output DC or AC?
As long as the circuit used in the transformer, the transformer output is certainly the AC voltage. This is because the DC is not through the transformer (no mutual inductance), so as long as the power circuit has a transformer, its output is certainly the AC voltage. Want to make the power supply output voltage for the DC voltage, through the rectifier circuit, the AC voltage rectifier rectifier voltage can be. Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.). Circuit symbols commonly used as the beginning of the number. Example: T01, T201 and so on.
Q:800kw motor how much transformer
Power supply voltage is how much, the motor rated voltage is how much, 0.4KV or 6KV, or 10KV. It is the starting mode is the frequency or other, consider more factors, it is recommended to consult the motor manufacturers more reliable.
Q:Why the computer water does not use transformer oil
In the weak, strong electricity, the cooling medium must be run in the insulating environment, weak environment for the insulation material is not high, even if the insulation damage suffered
Q:Where is the transformer used?
Transformers are suitable for applications where the voltage level is to be changed Need to change the impedance to match the front and rear impedance of the occasion It is necessary to increase the current supply as a booster
Q:What is the transformer absorption ratio (R60 / R15)
Generally, the absorption ratio should be greater than or equal to 1.3 as the absorption ratio is acceptable.
Q:Power transformer primary current and secondary current
Do not know what the specific content of the question you ask? If the relationship between the variable and the ratio, then the secondary current and primary current ratio of the transformer for a second and second turns ratio, the need for specific problems.
