ConcepcionS13-Oil immersed transformer
When the transformer is put into operation, if the tap changer is not in time a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.
Concepcion, Uruguay.The proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text,Concepcion, Uruguay2500kVA dry type transformer, we have already mastered the structure and characteristics of dry-type transformer. In this part, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.
The bearing capacity of each load is different. Generally, while oil transformer has better load working capacity.
.Oil immersed transformer
(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m, and a guardrail of no less than 7m shall be installed around it, and a warning sign shall be hung at a prominent position.
In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?
Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.
The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT100 temperature sensor embedded in the bottom voltage winding to immediately indicate the winding temperature of each phase (three-phase safety inspection and Zui large value indication, and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as 420mA analog quantity. If it is to be far away (the distance can reach 1200m,Concepcion, UruguayDry type transformer production process, the electronic computer can be equipped with an electronic computer socket, an intelligent transmitter, and 31 transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt100 thermistor sensor, so as to further improve the stability of the temperature maintenance system software.
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.
Product range.What is the wiring mode of dry-type transformer?
After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack,Concepcion, UruguayTransformer and box transformer, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.
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.
Oil leakage of bolt or pipe external thread
discount.The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
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.
Sound in case of phase failure
Concepcion, Uruguay.What about oil immersed transformer fire?
The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, that is most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, the disconnection component of the electric field is small.
Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, which dissolve and ignite, resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure, endangering all normal production
