Tabarka Three When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
The noise of dry-type transformer comes from
San Sebastian.The domestic transformer market is slow
Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation,San SebastianPower supply transformer, 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.
.What is the reason for the shutdown of power transformer?
Wiring mode of dry-type transformer:
Under normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer,San SebastianOil immersed high voltage transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.
Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, wind and sand.
This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.
During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.
Administration.When the full load test is carried out and everything is normal, the load can be connected.
In terms of the place of use, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;
In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
Careless maintenance and insulation damage
how much.& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by 1000V megger, the resistance value exceeds 2m ohm bus.
The common dry-type transformer is an important electrical equipment,San SebastianTransformer voltage, and the voltage is constantly regulated. However, because of certain necessity, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.
(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; 0mm galvanized wire shall be wound over 4 turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than 0.2m.
San Sebastian.Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes two-color short circuit fault or short circuit to ground fault and dissolution of oil.
