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?
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;

In the whole process of transmitting electromagnetic energy in the power supply system， it will inevitably cause the loss of voltage and output power. When transporting the same output power， the voltage loss is inversely proportional to the voltage， and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.
If the volume of power transformer is too small， the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore， the rated capacity of the transformer should be selected according to the power consumption， which is not suitable for too large or too small.
Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer， special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage， it shall be handled properly.
There is a magnetic induction line crossing in the transformer core，BograModel of three-phase oil immersed transformer， which will cause induced electromotive force on the plan with the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex， it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.
Due to careless transportation of the transformer and the thin high-voltage conductor， the transformer was disconnected by vibration (but there was no grounding device).
Where is goodWhen the manufacturer of the power transformer samples from the automobile oil tank， after opening the sealing cover，BograPrice of 2000kVA dry type transformer， clamp the branch pipe with your thumb， and loosen your thumb to make the oil enter the pipe，
The 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?
Seal oil leakage
The power transformer conductor refers to the connecting transmission line between each electromagnetic coil between the electromagnetic coil and the group outlet pipe， and between the electromagnetic coil and the tap changer.

Dry type transformer， a static electrical equipment， is used to change the AC current (current) of a certain standard value into another or several types of working voltage (current) with the same frequency and different standard values. According to the supervision sampling inspection data of the third quarter of last year released by AQSIQ， kinds of commodities were found to be inconsistent with the provisions of relevant specifications， with a compliance rate of %& ldquo; This result mostly shows the quality level of China"s dry-type transformer industry at the present stage.
The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation maintenance and transportation， and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.

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.
