MinasHigh efficiency and energy saving power transformerWhat are the operating procedures and maintenance of the production line?

Then clamp the branch pipe with your thumb,MinasPrice list of 630kVA box type transformer, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.

The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, large current flow and small characteristic impedance into high communication AC voltage small current and large characteristic impedance. When there is an AC circuit in the original coil, causing the magnetic induction voltage in the primary coil (or current).

The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts the communication AC magnetic flux will be caused in the transformer core (or magnetic core),MinasTransformer three-phase transformer, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.

.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, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.

Before no-load impulse closing, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.

(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; 0mm galvanized wire shall be wound over 4 turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than 0.2m.

The whole process of hanging the core of dry-type transformer is more critical, and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore, the hanging core of dry-type transformer should be carried out according to the above matters, so as to promote the safety of dry-type transformer!

Two point grounding device of iron core caused by residual welding scar;

Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.

Customer first.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.

Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil,MinasDistribution transformer quotation, insulated by insulating oil in the circulating system inside the transformer, and long-term scalding of iron core will lead to insulation aging.

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, please be rational to make the oil immersed transformer safer and more efficient.

discount.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.

During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.

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, snow, wind and sand.

Connection group structure of dry-type transformer

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
