Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage,TangierDry type transformer scb14, commerce, airports, tunnel construction, chemical enterprises and factories.
Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, wind and sand.
Tangier.If the input of dry-type transformer is an alternating switching power supply, its output voltage is directly proportional to the coil turn ratio of the output input solenoid coil. If a rechargeable battery is used, because it is DC, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way, the alternating DC current can be obtained at the output end.
Naturally, 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, which can control the oscillation below 0.2%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.

Careless maintenance and insulation damage
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, 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,TangierPower transformer specification, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.
In order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as y4cs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.
Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.
target.For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.

Manufacturing process and steps of dry-type transformer
How much does it cost?.Falling foreign matters and piercing
Many people probably don't know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.
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.
Tangier.Noise pollution control and prevention measures of dry-type transformer
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation and overload is not allowed in the whole process of operation.
