KohayokiModel of power dry-type transformerWhat are the types

It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.What is the reason for the shutdown of power transformer?Kohayoki,The domestic transformer market is slowThe vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.Kontiolahti,Careless maintenance and insulation damageThere are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.What is the wiring mode of dry-type transformer?

What is the wavelength of oil immersed transformer?The common dry-type transformer is an important electrical equipment, 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.The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection,What about oil immersed transformer fire?The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection,KohayokiFunction of oil immersed transformer, wipe the Fushi blue film remover on the surface,KohayokiHow much is a box transformer,KohayokiOil immersed transformer 1600KVA, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.

In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?Test results,Causes of fire in power transformerThere 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.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, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.Kohayoki,(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than m; At the angle with actual operation a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.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.Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, which dissolve and ignite, 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.
