Dry type transformer when work is a lot of problems need to be aware of, one of the most important is the problem of dry type transformer current and voltage to be carefully to find out, the dry type transformer is voltage distribution of all kinds, large and small voltage controls the overall operation, and even ACTS as a more important role in the circuit, the dry type transformer voltage distribution in dry type transformer body, is mainly the stability of the main factors of the performance of the dry type transformer. The distribution of the dry type transformer is scientific and reasonable, so the distribution of the dry type transformer's voltage cannot be ignored.
The electromagnetic design of frequency converter shall carry out the electromagnetic design of dry type transformer according to the technical and performance parameters specified in the bidding document and contract agreement, and determine the main dimensions and electromagnetic loads of the product. Short circuit impedance calculation short circuit impedance is an important performance parameter of dry type transformer. It determines the voltage change of dry type transformer under load condition and the current when short circuit condition, and it is also the condition of parallel operation of dry type transformer. Therefore, accurate calculation of short circuit impedance of dry transformer is of great significance to the operation of dry transformer. Coil short-circuit strength calculation in large dry type transformer short-circuit current is rated current of the 8 a 10 times, due to the short circuit force is proportional to the square of the short circuit current, so in short circuit winding leakage magnetic field and turns under the interaction of current, it will produce great electric effect on the winding turns, winding structure can produce permanent deformation and damage.
In addition, the relative displacement of wire insulation and other parts of winding may damage the insulation and lead to the line-turn short circuit. The coil short-circuit strength calculation is mainly to calculate the size and distribution of the force on each section of the coil in the case of the dry-type transformer short-circuit, and to check whether the mechanical strength of the coil meets the requirements. It is very important to calculate the voltage distribution of the coil impulse for large dry transformers. The dry type transformer allows the continuous working voltage to be no more than 5% of the rated voltage. The transformer may produce overvoltage during operation. Overvoltage is mainly caused by operation fault or lightning strike.
The distribution process of the dry type transformer voltage is the above several. The distribution of the dry type transformer voltage should be grasped as a whole. In this way, the control and operation rules of the dry type transformer can be mastered. If you don't know, please pay attention to the knowledge part of our dry transformer.
