Saint VicentePIn specific daily life, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.
.Some are tied with plastic tape, and some immediately press the two edges together,Saint LaurentDry type transformer 10 / 0.4kV,Saint Laurent500 KVA oil immersed transformer,Saint LaurentTechnical parameters of power transformer, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.
Protective measures for damping of dry-type transformer
How to reduce the failure of dry-type transformer?
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface, the treatment goal can be achieved.
How is the quality level of dry-type transformer compared with foreign countries?
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.
query.What is the wavelength of oil immersed transformer?
Dry type transformer
Power transformer manufacturer
In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuit
Click to view.From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;
When the operating oil is mixed with different types of new oil or used for oil, in addition to the accurate measurement of the cold filter point of the mixed oil, it is also necessary to carry out high and low temperature test and sludge test, and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor, so it can be managed and used in a mixed manner.
The voltage regulating tap changer is not in place or poor
Saint Laurent.The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.
(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.
The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by 20%.
