MahendranagaHo& ldquo; YN,Mianchan nunneryInsulating oil of oil type transformer, D11 & rdquo;, in which 11 indicates that when the working voltage phasor of the primary side line,Mianchan nunneryPrice of oil immersed transformer, as the minute hand, refers to the position at 12 o'clock, the phase voltage phasor of the secondary side is at 11 o'clock. That is, the phase voltage UAB of the secondary side lags 30 degrees behind the working voltage uab330 of the primary side line (or 30 degrees ahead).
Fault judgment of power transformer
Mianchan nunnery.How to make up oil for oil immersed transformer?
(III) dry type transformers of 315KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than 5m; The distance between the electrified part and the road surface shall not be less than 5m.
.The key reason for oil leakage is that there are defects in cast iron parts
Noise dispersion of dry-type transformer
What is the important role of power transformer
Seal oil leakage
Power saving analysis of transformer
Protective measures for damping of dry-type transformer
Which one is better.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.
What is the wavelength of oil immersed transformer?
On load commissioning:
After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.
Where to sell API.Oil immersed transformer
Transformer inspection ear
High voltage fuse of transformer breaks one phase;
Mianchan nunnery.When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.
(I) the distance between the external contour of 10kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than 1m; At the angle with actual operation,Mianchan nunneryFunction of main transformer in power plant, a spacing of more than 2m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
