Dry type transformer manufacturer
The flange surface is uneven， the tightening bolts are loose， and the installation and processing process is wrong， so that the bolts are not tightened well， resulting in oil leakage.
MulvibazaThe 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;
In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer， prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

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?
When the output power P of the transformer is equivalent to the input power P， the efficiency & ETA; Equivalent，MulvibazaDry type power transformer brand， the transformer will not cause loss. But in fact， there is no such transformer. The electromagnetic energy of transformer always causes loss. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil， part of the electromagnetic energy changes into energy and is lost. Because the electromagnetic coil is generally wound by copper core wire with insulating layer， it is called copper loss.
When the full load test is carried out and everything is normal， the load can be connected.
Variable costGenerally 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，MulvibazaOil immersed transformer， 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 sampling container shall be cleaned with vehicle gasoline， soapy water or other organic solvents (such as trisodium phosphate) except oil stains， and then washed with tap water until it is not alkaline， and the water can be evenly distributed from the bottle， and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration， the bottle cap shall be tightly closed and cannot be opened before application.
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials porcelain， laminated glass and other materials very well，MulvibazaPower transformer model definition， so as to achieve the pressure management of oil leakage.
knowledgeGenerally speaking the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer， 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.
During the operation of the transformer， the resistance value of the grounding wire shall be measured accurately every two years.
There 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.
MulvibazaThe manufacturing process of dry-type transformer is very process， and must be technically as a certain pillar. Only in that way， the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
