Operation of oil immersed transformer
Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window， ventilation and air exchange port and road surface， and apply sound insulation window， silencing cylinder，RecifeWhat are the power transformers， the cost of energy-saving transformers is significantly higher than that of traditional transformers， and the price factor is also a key factor endangering the popularization and marketing of energy-saving transformers. Although there are energy-saving and convenient subsidy projects to help energy-saving transformers， the market has not yet fully operated.
Brief introduction of zero line of power transformer
LaucaSound， causing short circuit obstruction. If not handled properly it will cause great damage.
Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core， and long-term scalding of iron core will lead to insulation aging.
What is the important role of power transformer
There are many connection groups of dry-type transformers， and the selected structures and connections are also different. Then， what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.
The common dry-type transformer is an important electrical equipment， and the voltage is constantly regulated. However， because of certain necessity， the dry-type transformer will also boost voltage， and the whole process of boosting voltage is very complex， and there are many principles.
(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.
Installation requirements(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer， and the distance shall not be less than m; At the angle with actual operation， a spacing of more than m shall be reserved; If metal fence is selected， the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct， which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment， the output capacity can be increased by %.
Generally speaking， the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer， disconnect the switching power supply on each side， quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited， the generator set must be disassembled first.
The noise of dry-type transformer belongs to low-frequency noise. In a small area， most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building and then causes gas vibration noise， which is then scattered to the ears of consumers. Although the amount of noise is not very large， the dispersion spacing and adverse effects are very large.
Quality improvementDuring no-load test run， and then make the working voltage impulse closing.
In 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 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.
When we apply oil immersed transformer， we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
RecifeA zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let"s introduce it to us.
Gradually， high-frequency vibration damping mechanical equipment， such as low-frequency vibration damping platform， is installed at the bottom of the dry-type transformer， which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings，RecifePrice of 5000KVA transformer， roads， etc. with flexible connection， or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible，RecifeWhich is a good oil immersed power transformer， the dry-type transformer room can also be soundproofed and decorated， and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin， insulated by insulating oil in the circulating system inside the transformer， and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
