For no-load impulse closing of transformer， pay attention to the following matters:
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.
MartabanPrinciple of step-up dry-type transformer: the step-up dry-type transformer is a component that correspondingly converts low communication AC voltage， large current flow and small characteristic impedance into high communication AC voltage， small current and large characteristic impedance. When there is an AC circuit in the original coil， the communication AC magnetic flux will be caused in the transformer core (or magnetic core) causing the magnetic induction voltage in the primary coil (or current).
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， so as to promote the safety of dry-type transformer!
Yongwang， get upIn fact，MartabanPower supply and distribution transformer， ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them， safety factor grounding device can be divided into grounding protection， anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.
(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m， and a guardrail of no less than m shall be installed around it， and some immediately press the two edges together， and there is still oil leakage without sealing effect.
Dry type transformer is a common electrical equipment， which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries such as variable frequency power supply.
Some are tied with plastic tape， and some immediately press the two edges together， because the socket can not be pressed firmly during installation， and there is still oil leakage without sealing effect.
Where can I find it?The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side)， and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring， and D (or D) is triangular wiring.
In terms of the place of use， dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire， and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;
(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m， and a guardrail of no less than m shall be installed around it， and a warning sign shall be hung at a prominent position.
After sampling， bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
Supply chain quality managementPower transformer
How to maintain dry-type transformer?
The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core，MartabanBox type transformer recycling manufacturer， which is resistant to corrosion and rust，Martaban800 dry type transformer quotation， and has sound insulation and noise reduction.
MartabanAfter tightening the loose bolts seal the flange， and solve the bolts that are likely to leak， so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.
The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name， source， sampling date， sampling person， weather conditions and other materials of the oil sample.
