How to reduce the failure of dry-type transformer?
Zdunskavora.Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.
Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.

Operation of oil immersed transformer
From the appearance,ZdunskavoraPrice of 1000 KVA transformer, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;
(I) the distance between the external contour of 10kV 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 1m; At the angle with actual operation, a spacing of more than 2m 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.
Many people probably don't know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration,ZdunskavoraModel of dry-type power transformer, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.
When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.
how.The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.
Protective measures for damping of dry-type transformer
Operation of oil immersed transformer
The 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.
Quality recommendation.Power transformer
Maintenance contents of power transformer
35kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, the winding of oil immersed transformer is generally divided into multiple modules and each module is replaced by an equivalent circuit, 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.
In the case of dry-type transformer operation, there is more noise,ZdunskavoraDry type transformer box type transformer, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.
The whole process of hanging the core of dry-type transformer is more critical, and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore, the hanging core of dry-type transformer should be carried out according to the above matters
