Naberezini cheWhen the transformer is out of phase, if the second phase is blocked, 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, as in the case of the second phase. There are three reasons for phase deficiency:
In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?
Guaran.For oil transformer oil replenishment,GuaranCode for installation of power transformers, 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.
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.
.Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings,GuaranFunction of oil immersed transformer, commerce, airports, tunnel construction, chemical enterprises and factories.
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?
Oil leakage of cast iron parts
The voltage regulating tap changer is not in place or poor
This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.
The project cost is different. Compared with the purchase price of capacity transformer, connect the data signal contact of the automobile relay with the alarm circuit the pull-in contact with the opening circuit,GuaranDry type transformer temperature standard, it is a common fault of the winding. Then carry out the appearance inspection of the iron core and adjust the overcurrent protection value.
Oil leakage of cast iron parts
The switching power supply lacks one phase of power;
The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.
Quality risk.Causes of fire in power transformer
Accurately measure the resistance of each phase winding and carry out the measurement. If there is a great difference, and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large, paint the damaged part.
Protective measures for damping of dry-type transformer
Guaran.What is the important role of power transformer
The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
