Boya HotelAppl
EdPrice list oThe project cost is different. Compared with the purchase price of capacity transformer,Boya HotelComprehensive protection of power transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
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, so as to achieve the pressure management of oil leakage.
Boya Hotel.When the output power P2 of the transformer is equivalent to the input power P1, the efficiency & ETA; Equivalent, 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, it is called copper loss.
Operation of oil immersed transformer
.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, causing short circuit obstruction. If not handled properly, it will cause great damage.
For no-load impulse closing of transformer, pay attention to the following matters:
It should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international,Boya HotelWhat are the protections for oil immersed transformers, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.
The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.
Where is good.Careless maintenance and insulation damage
Noise dispersion of dry-type transformer
The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core which is stacked at the 45 degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.
The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.
Honest management.What about oil immersed transformer fire?
Several detection methods for installing transformer
In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.
Boya Hotel.Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below 0.2%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.
Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling,Boya HotelStructure introduction of oil immersed transformer, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.
The conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.
