Power transformers are used in all walks of life
Treliu.The rate of transformer is: n = P2 / p1x1o%, that is,Treliu10kV transformer oil immersed, the rate is very large. Therefore, the load of transformer is: 0 = P / PK. Fully consider the active power loss caused by reactive power in the system software during transformer operation. The load adjustment is: it can be seen from the calculation of load formula that the large rate of transformer does not occur when the load is full, Generally, it is about 50%, but when selecting the transformer capacity, we should select effective transformers according to the load condition and load, 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.

On load commissioning:
For 630kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
Wiring mode of dry-type transformer:
For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than 5% there is generally no problem. However, if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.
Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation,TreliuPartial discharge standard for dry type transformer, and there is still oil leakage without sealing effect.
packing.Operation of oil immersed transformer
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, and then take the oil sample.
What about oil immersed transformer fire?

total cost.Before no-load impulse closing,TreliuParameters of 1000 KVA oil immersed transformer, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
When the output power P2 of the transformer is equivalent to the input power P1, the transformer will not cause loss. But in fact, there is no such transformer. The electromagnetic energy of transformer always causes loss. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil, part of the electromagnetic energy changes into energy and is lost. Because the electromagnetic coil is generally wound by copper core wire with insulating layer, it is called copper loss.
The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.
Treliu.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.
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
