Zhtkavic80 KVA oil immersed transformerSmooth start but still weak

Oil leakage of cast iron partsThe 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.Zhtkavic,With Vietnam and Malaysia, China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world, occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.The hanging core of dry-type transformer is a vital partMontego-Bay,If the above provisions are not met, the problem of dryness shall be solved. Generally, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct, and there shall be no dirt.& ldquo; YN, 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).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.

After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.Transformer inspection earThe voltage regulating tap changer is not in place or poorProcess inspection,Dry type transformer manufacturerWhen the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb,ZhtkavicPower transformer function, and loosen your thumb to make the oil enter the pipe,The switching power supply lacks one phase of power;

If the oil immersed transformer is burned by the cover of the transformer when the oil immersed transformer fails,Zhtkavic33kV power transformer, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.agent,Zhtkavic80 KVA oil immersed transformer,Oil leakage of cast iron partsAccurately measure the resistance of each phase winding and carry out the measurement. If there is a great difference, it is a common fault of the winding. Then carry out the appearance inspection of the iron core, and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large, paint the damaged part.During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.Zhtkavic,Power transformer manufacturerUnder normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation the operation and maintenance management staff shall improve the safety inspection range of the transformer, so as to ensure the reliable and stable operation of machinery and equipment.Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
