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.
Avoid the load operation of power transformer: if the load operation is long-term it will lead to the scalding of solenoid coil, slow aging of insulation, two-color short circuit fault or short circuit to ground fault and dissolution of oil.
Janduba.The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment,JandubaOil immersed air-cooled transformer, such as discoloration, deformation, offset, cracking, loosening, ignition smoke, oil leakage, broken strand disconnection, short-circuit fault marks, etching and turbidity, which can be inspected according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.
If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.
.In the case of dry-type transformer operation, 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.
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, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.
Performance and main parameters of common metal composites, various welding processes and machinery and equipment, preparation treatment of thick steel plate, blanking process, production and manufacturing process and quality standards of automobile oil tank, riser, coupling and oil storage tank cabinet, welding leakage test and NDT technology, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process, body dryness solution and dry transformer oil solution process,JandubaLoss table of distribution transformer,JandubaStandard for AC withstand voltage test of power transformer, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.
Power transformer
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, 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.
In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuit
recommend.When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,
The hanging core of dry-type transformer is a vital part
The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is, the disconnection component of the electric field is small.
Inspection standard.It includes the performance and main uses of insulating layer materials, various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.
In fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.
In the case of using dry-type transformer, it is easy to cause common faults in application. So what is the wiring mode of dry-type transformer?
Janduba.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, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
For 630kVA 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.
(III) dry type transformers of 315KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than 5m; The distance between the electrified part and the road surface shall not be less than 5m.
