LanceMain transformer of wind farmHow to sell
If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore,LanceTemperature standard for oil immersed transformers, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.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,LanceScb13 dry type transformer with secondary energy efficiency, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.Lance,The grounding resistance of, high voltage and bottom voltage shall not be less than % (m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed %, which shall not exceed % compared with the last accurate measurement result.The whole process of hanging the core of dry-type transformer is more critical, the hanging core of dry-type transformer should be carried out according to the above matters, so as to promote the safety of dry-type transformer!HerzonUse fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss,LanceStructure of 35 kV oil immersed transformer, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.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, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.The insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;The input and output three-phase power lines shall be connected to phase a, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.Respect for customers,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, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment the output capacity can be increased by %.A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, and has sound insulation and noise reduction.
When the full load test is carried out and everything is normal, the load can be connected.reform,The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV, which also ensures the rated voltage of kV; Oil immersed transformers are generally suitable for distribution equipment.This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.Dry type transformer factoryLance,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, snow, wind and sand.The voltage regulating tap changer is not in place or poorNoise pollution control and prevention measures of dry-type transformer
