The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:The noise of dry-type transformer comes fromSiroli,There is a magnetic induction line crossing in the transformer core, which will cause induced electromotive force on the plan with the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex, it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.The method and whole process of taking oil sample of power transformer are as follows:Bonoua,Operation of oil immersed transformerCaused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.

The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.It should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.Operation of oil immersed transformersystem,Common problems of tap changer of power transformerHigh voltage fuse of transformer breaks one phase;The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.

How much is the power transformerCreate brilliance,Analysis of common faults of oil immersed transformer:Overtemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again,Siroli10kV dry type transformer test, if it reaches ℃, the overtemperature trip data signal must be transported to the secondary maintenance circuit, and the transformer shall be tripped quickly.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?Siroli,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,Siroli3000 oil immersed transformer,SiroliPrice of 200 KVA box type transformer, 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).For kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.Gradually, high-frequency vibration damping mechanical equipment such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.
