Bunúsach Réamhrá Le Dáileadh Claochladáin

Tagraíonn dáileadh claochladán do a statach leictreach gléas a úsáidtear in an dáileadh córas go athrú AC voltas agus reatha de an dlí de leictreamaighnéadacha ionduchtú agus tarchur AC leictreach fuinneamh . Sínis claochladán táirgí is féidir go ginearálta a bheith roinnte i ultra-ard voltas (750KV claochladáin / 7b 7b % 7b4% 7d% 7dKV claochladáin% 2c agus 35KV agus thíos claochladáin bunaithe ar voltas leibhéil. Dáileadh claochladáin de ghnáth tagairt do cumhacht claochladáin oibriú in an dáileadh líonra le a voltas leibhéal de % 7b % 7b6% 7d% 7dKV agus a cumas de 6300KVA nó thíos go go díreach soláthar cumhacht go deiridh úsáideoirí.
A distribution power transformer is a static electrical device used to convert a certain value of AC voltage (current) into another or several different values of voltage (current) with the same frequency. When alternating current is applied to the primary winding, alternating magnetic flux is generated. The alternating magnetic flux is induced in the secondary winding through the magnetic conduction effect of the iron core, resulting in an alternating electromotive force. The height of the secondary induced electromotive force is related to the number of turns in the primary and secondary windings, that is, the voltage is directly proportional to the number of turns. The main function is to transmit electrical energy, therefore, rated capacity is its main parameter. Rated capacity is a commonly used value to represent power, which characterizes the size of transmitted electrical energy, expressed in kVA or MVA. When a rated voltage is applied to a transformer, it is used to determine the rated current that does not exceed the temperature rise limit under specified conditions. The most energy-efficient power transformer is the amorphous alloy iron core distribution transformer, which has the greatest advantage of having a particularly low no-load loss value. Whether the final no-load loss value can be ensured is the core issue to be considered throughout the entire design process [2]. When arranging the product structure, in addition to considering that the amorphous alloy iron core itself is not subjected to external forces, it is also necessary to accurately and reasonably select the characteristic parameters of the amorphous alloy during calculation. The major domestic manufacturers of power transformers include TBEA, Shandong Mingda, and TBEA Luming Transformers.
