Madaba Price oMadaba Structure diagram of oil immersed power transformer,
The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).
Madaba .Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, if it is necessary to use new oil of different grades, it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region, and then the oil mixing test should be carried out.
Causes of fire in power transformer
.Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, which dissolve and ignite, resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure, endangering all normal production, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.
When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
Falling foreign matters and piercing
Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.
How to select dry-type transformer
What is the reason for the shutdown of power transformer?
query.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.
Naturally, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.
Operation and maintenance management of oil immersed transformer
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.
Customer first.During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side,Madaba How much is a 100 KVA box transformer,Madaba Power equipment transformer, and then make the working voltage impulse closing.
Under normal conditions, if it is necessary to use new oil of different grades it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region, and then the oil mixing test should be carried out.
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
Madaba .Oil immersed transformer company
The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.
