IzygumPrice of 400 KVA box transformerEssence

which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment

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, the output capacity can be increased by %.How to reduce the failure of dry-type transformer?Izygum,The fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate, the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, and then the iron loss is considered and the copper loss is ignored. In fact, for a certain load, the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer, so it consumes electromagnetic energy.Before no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.Madaoua,Power transformerDry 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.Noise pollution control and prevention measures of dry-type transformer

Seal oil leakageOil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.Method and process of taking oil sample of power transformerPromotion,The switching power supply lacks one phase of power;Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).Protective measures for damping of dry-type transformer

It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.Highly recommended,If 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,IzygumDifference between oil immersed transformer and dry-type transformer, the insulation resistance from the secondary side to the ground should be ^ mh, and then the iron loss is considered and the copper loss is ignored. In fact the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, for a certain load, the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer, pay attention to the following matters:Izygum,Oil leakage at electric welding positionThe technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω, The resistor is generally more than & omega;, According to Ohm's law, when the insulating layer is damaged, the current is only / of the total current flow, so as to play a guarantee effect. The higher the voltage, the smaller the resistance,IzygumWhat is the main function of power transformer, in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.Dry type transformer company
