How to reduce the failure of dry-type transformer?
Tilstrop Airport.This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.
Dry type transformer
.Difference between dry-type transformer and oil immersed transformer:
The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.
When using the oil sample of the power transformer in operation,Tilstrop AirportOil immersed transformer 50KVA, 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, and then take the oil sample.
Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.
How to maintain dry-type 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, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
Application process.Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary the load can be reduced or the operation of the transformer can be stopped.
When sampling in bulk gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles samples shall be selected according to 5% of the number of gasoline barrels, samples shall be taken according to 2% of the total number of barrels (bottles).
After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.
Deterioration damage of transformer core insulation
Total quality assurance.What is the reason for the shutdown of power transformer?
Hand touch method for transformer inspection
The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.
Tilstrop Airport.Power transformers are also used for testing, 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.
In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word if there is any problem at a certain point, it will affect the whole power circuit
In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than 0.5kg, and the oil sample for simplified experiment shall not be less than 1kg.
