PatanOld box tWhen sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.
Singapore.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 2012 providing subsidies of 4-30 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?
.How to reduce the failure of dry-type transformer?
The flange surface is uneven, the tightening bolts are loose,SingaporeConstruction procedure of oil immersed transformer, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.
Loose core screw
Gradually, high-frequency vibration damping mechanical equipment,SingaporeAmorphous alloy transformer and oil immersed transformer, 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, roads,Singapore10kV oil immersed distribution transformer, 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.
How is the quality level of dry-type transformer compared with foreign countries?
How much is the power transformer
Customer first.(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m, and a guardrail of no less than 7m shall be installed around it, and a warning sign shall be hung at a prominent position.
The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
Power transformer
Test results.Deterioration damage of transformer core insulation
After the power transformer has been used for a long time common faults of iron core will occur. Don't worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:
Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.
Singapore.Sound in case of phase failure
The main reason is that the welding quality of electric welding is poor, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
