HalleyParameters of 500 KVA oil immersed transformerWhat is the application principle of

The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.Halley,Transformer inspection nose sniffing methodHow much is the power transformerDouglas,& 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 V megger, the resistance value exceeds m ohm bus.The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.In the case of using dry-type transformer customers must master the method of wiring. If there are problems in wiring,Halley2000 KVA dry type transformer, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?

The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.Transformer isIf the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %), it should be insulated before putting into use, and accurately measured with a V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ mfl, the insulation resistance from the secondary side to the ground should be ^ mh, and the insulation resistance from the iron core to the ground should be & amp; gt; mfl (note that the grounding device piece should be removed).technical service,The voltage regulating tap changer is not in place or poorFor example, in the s, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.

When the whole process of winding wave of oil immersed transformer is calculated by using the marking method the winding of oil immersed transformer is generally divided into multiple modules, and each module is replaced by an equivalent circuit,HalleyParameters of oil immersed power transformer, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.Quality inspection report, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;How much is the power transformerHalleyUnder 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, 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.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.For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, damage to machinery and equipment, etc.
