There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.
Busia.In order to promote the use of energy-saving transformers, 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 2012, providing subsidies of 4-30 yuan / KVA for energy-saving transformers.
How much is the power transformer
.Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, 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.
From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.
The fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate, the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, and then the iron loss is considered and the copper loss is ignored. In fact, for a certain load, so it consumes electromagnetic energy.
Oil leakage at electric welding position
Range.If the power transformer stops running for more than 72h (if the allowable time should be reduced when the ambient humidity is & amp; gt; 95%), it should be insulated before putting into use, and accurately measured with a 2500V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ 300mfl, the insulation resistance from the secondary side to the ground should be ^ 100mh and the insulation resistance from the iron core to the ground should be & amp; gt; 5mfl (note that the grounding device piece should be removed).
In 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?
How to reduce the failure of dry-type transformer?

Trustworthy.Connection group structure of dry-type transformer
Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.
The whole process of hanging the core of dry-type transformer is more critical, and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore, the hanging core of dry-type transformer should be carried out according to the above matters so as to promote the safety of dry-type transformer!
Busia.Oil leakage at looper flange
When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels,BusiaDry type transformer Report,BusiaParameters of oil immersed transformer, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to 2% of the total number of barrels (bottles).
Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform,BusiaOperating temperature range of dry-type transformer, 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, 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, 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.
