Noise solution of dry-type transformer
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.
MaimensinFirst of all， although dry-type transformer has strong moisture resistance， it is generally open structure or very susceptible to moisture， especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore， the dry-type transformer can obtain high stability only when the air humidity is below %. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than / V (operating voltage)， it indicates that the transformer is seriously damp， and the trial operation shall be terminated.
After 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.
TraThe zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance， the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety， it is more and more unreliable. Ground wire (PE): it is not used as a working circuit， the current will be quickly grounded. Even if there is a lead for the PE line， it will be grounded from the surrounding grounding body.
The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?
Sound，MaimensinDry type transformer， causing short circuit obstruction. If not handled properly， it will cause great damage.
Operation of oil immersed transformer
Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact， but consuming electromagnetic energy.
Due to poor sealing generally， the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well， it will lead to common faults of oil leakage.

With the rapid development of society and the continuous development trend of computers， the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed， the accuracy of calculation conclusions can meet the needs of architectural design， and scientific and reasonable data method is selected， Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage， but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.
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.
Sales DepartmentThe vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment， the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.
How to maintain dry-type transformer?
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut)， wipe the Fushi blue film remover on the surface， and then tighten it after wiping the raw materials on the surface. After drying， the treatment goal can be achieved.

For no-load impulse closing of transformer， pay attention to the following matters:
After sampling， bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
