The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, different oil-based oils cannot be mixed. Under special circumstances if it is necessary to use new oil of different grades, it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region, and then the oil mixing test should be carried out.
The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.
.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.

How to reduce the failure of dry-type transformer?
How to maintain dry-type transformer?
The key reason for oil leakage is that there are defects in cast iron parts
Focus on Development.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,Dogon DorchDry type transformer 125kva, 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.
The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor,Dogon DorchDistribution transformer analysis, power transformer winding and power transformer tapping power switch are analyzed below:
The flange surface is uneven, the tightening bolts are loose, so that the bolts are not tightened well, resulting in oil leakage.
High voltage fuse of transformer breaks one phase;
Quality documents.Loose core screw
The secondary inductive equipment of the distribution station (such as transformer, voltage transformer, automobile relay, AC, etc.) operates normally. According to the AC current, the winding transformer core will send out a symmetrical rhythm and a certain tone & ldquo; Buzz, buzz & rdquo; Sound. The operation staff of the transformer manufacturer should understand and grasp the characteristics of the noise. When the equipment has common faults, there will be noise and even & ldquo; Crackle & rdquo; The charging and discharging sound can distinguish the generation and characteristics of common equipment faults according to the music law and sound transformation when everything is normal and abnormal.
Solenoid insulation deterioration
Dogon Dorch.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?
For no-load impulse closing of transformer, pay attention to the following matters:
The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.
