WeltWaste power transformerAnalysis and research on the causes of cracks

Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?

Welt.Transformer

Difference between dry-type transformer and oil immersed transformer:

.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?

When the full load test is carried out and everything is normal, the load can be connected.

Power transformers are used in all walks of life

Power transformer manufacturer

Relevant responsible persons of the transformer Federation of China Household Appliance Industry Association show that the development prospect of transformers in China in the future is still the development trend of environmental protection, low noise, fire safety and explosion-proof and high reliability. There are two key development prospects: one is the development trend of high voltage and high voltage, especially 750kV and 1100kV. The second is the development trend towards environmental protection energy conservation and miniaturization. The former key is applied to the long-distance substation project route, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.

investment.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well,WeltMarket price of scb11 dry type transformer, so as to achieve the pressure management of oil leakage.

The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.

A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?

After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.

Test results.Careless maintenance and insulation damage

The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, its orientation and size change with the change, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy,Welt315 KVA oil immersed transformer, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.

Method and process of taking oil sample of power transformer

Welt.When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet, then lower the bell cover anchor bolt of the large cover first take out the low-voltage waterproof sleeve and the on load transformer power switch, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear 4 round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for 100mm, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core,WeltParameters of 1600KVA dry type transformer, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.

(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; 0mm galvanized wire shall be wound over 4 turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than 0.2m.
