Plug in the power with full load first， ignition check whether the equipment has abnormal sound， odor and other abnormal conditions. If there is any abnormality， please cut off the input switching power supply.
Dorney KubinHow to select dry-type transformer
& ldquo; YN，Dorney KubinBox type transformer 160KVA price， D & rdquo;， in which indicates that when the working voltage phasor of the primary side line， as the minute hand， refers to the position at o"clock， the phase voltage phasor of the secondary side is at o"clock. That is， the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).

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.
Equipped with a temperature controller， platinum thermistor (pt) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer， stop the cooling centrifugal fan， set up common problem alarm， overtemperature alarm and overtemperature tripping effect， and provide reliable overvoltage protection machinery and equipment for the dry test transformer， so as to test the safety performance of the transformer operation.
There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let"s master and consult in detail with the small editor of the dry-type transformer manufacturer.
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， among the kinds of dry-type transformer commodities manufactured by manufacturers in provinces and municipal districts across the country， 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.
Plug in the power with full load first observe and detect that the input and output voltage meets the regulations. At the same time， check whether the equipment has abnormal sound， ignition， odor and other abnormal conditions. If there is any abnormality， please cut off the input switching power supply.
Click to viewDue to careless transportation of the transformer and the thin high-voltage conductor， the transformer was disconnected by vibration (but there was no grounding device).
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， which is not suitable for too large or too small.
Gradually， high-frequency vibration damping mechanical equipment， such as low-frequency vibration damping platform， is installed at the bottom of the dry-type transformer， which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings， roads， etc. with flexible connection，Dorney KubinDry type transformer function， or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible， the dry-type transformer room can also be soundproofed and decorated， and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.
Due to poor sealing， 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.
reformNaturally， if the oil immersed transformer catches fire， please don"t panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire， please be rational to make the oil immersed transformer safer and more efficient.
The dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.
Therefore in the operation prevention and regulation of relay protection dry-type transformer， it is necessary to find the short-circuit fault point according to the fault situation， lock the fault point，Dorney KubinOil immersed transformer thermometer， and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time， if all fields are clear， disconnect the switching power supply at the fault point， the maintenance work of employees will be carried out smoothly， and the harm will not expand to a greater extent.
Dorney KubinPlug in the power with full load first， observe and detect that the input and output voltage meets the regulations. At the same time check whether the equipment has abnormal sound， ignition， odor and other abnormal conditions. If there is any abnormality， please cut off the input switching power supply.
The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions， including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance， capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation， the good model is the solid model of infinite transformer core column， but there are many calculation methods.
