Design scheme of frequency air oxidation switching power supply. Because the output waveform is a waveform, it is beneficial to improve the sealing quality, reduce the melting of the film caused by the temperature rise, prevent the expansion of the pores of the air oxide film, improve the strength and relative density of the air oxide layer, improve product quality, and improve product quality. out rate.
What are the recommended high-frequency air oxidation switching power supply characteristics for high-current output?
1. Voltage stability, stable current and other controls.
2. Full digital display of current, voltage, working time, frequency meter (optional), component instrument (optional), etc. with high precision and sound and light alarm.
3. Soft start and stop function, with automatic maintenance functions such as overcurrent, overvoltage, undervoltage, overheating, short circuit, etc., with high reliability.
4. Strict tests and long-term aging tests have been carried out on the equipment before leaving the factory. It operates continuously day and night, with an average trouble-free running time (≥) of 50,000 hours. The failure rate is extremely low, and it is true, reliable and durable.
5. Carry out anti-corrosion treatment on the whole machine, seal the control unit, select the sealed B-type anti-corrosion head, and process the sealant of each delivery joint to avoid the corrosion of acid, alkali and salt gas, and ensure long-term stable operation in the corrosive environment .
6. The fully imported pvc shell or spray-painted metal shell is beautiful and will not corrode. It has a direct air-cooled structure and is very convenient for equipment maintenance.
7. The actual realization of pulse output with high current, high frequency and high working ratio.
8. Efficiency (≥95%) and obvious energy saving.

Dry-type transformers are widely used in residential and commercial buildings, especially in areas with high population density, strict fire safety requirements, and space constraints. Their fire and explosion protection, low noise, and maintenance-free characteristics perfectly meet the safety and environmental needs of the building industry.
What are the fire safety measures for dry-type transformers?
The fire safety measures for dry-type transformers mainly include the following aspects.
There are many differences in the application scenarios of resin dry transformers and impregnated dry transformers.
"Key components of modern power systems: the role of dry-type power transformers"
As a key component in modern power systems, dry-type power transformers not only meet the energy conversion needs of the power system, but also meet the requirements of environmental protection and safety. In the future, with the advancement of technology and the expansion of application scope, dry-type power transformers will play a more important role in the power industry and bring more efficient, stable, and environmentally friendly power services to people.
What should I do if the transformer suddenly short-circuits? Do you know these reasons?
To deal with transformer short-circuit accidents in daily operations, it is necessary to find out the essence of the problem through inspection and testing. When the transformer suffers from a sudden short circuit, both the high and low voltage sides will be subject to a large short-circuit current. In the short time before the circuit breaker can be disconnected, the short-circuit current will generate an electromotive force proportional to the square of the current that will act on the winding of the transformer. Electrodynamic force can be divided into radial force and axial force.
How much kW power consumption can a 1000kVA transformer withstand?
KVA (kilovolt-ampere) is the unit of apparent power, and KW (kilowatt) is the unit of active power. In addition to apparent power and active power, there is also reactive power, and the unit of reactive power is Kvar (kilovar).
