San BenitoOil immersed transformerHow to operate and debug it

Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.

Oil leakage at electric welding position

San Benito.How to make up oil for oil immersed transformer?

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, if the second phase is blocked it will affect the whole power circuit

.When the transformer is out of phase, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.

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, the disconnection of the fault point is related to each other. In a word,San Benito100 box type transformer, if there is any problem at a certain point, it will affect the whole power circuit

When the output power P2 of the transformer is equivalent to the input power P1, the efficiency & ETA; Equivalent, the transformer will not cause loss. But in fact,San BenitoInstallation drawing of dry-type transformer,San BenitoMain parameters of oil immersed transformer, 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.

How much is the power transformer

Pursuit of excellence.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

What is the reason for the shutdown of power transformer?

How much is the power 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.

Quality improvement.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?

The domestic transformer market is slow

The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.

San Benito.The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.

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.

The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by 20%.
