Dry type transformer is also an important power equipment, is also an important electrical appliances, dry-type transformer in the use and work process is constantly heating, only continuous heating can produce energy. For the heat output of dry-type transformer, it indicates the performance and efficiency of various use of dry-type transformer. The heat output of common dry-type transformer is calculated in this way, and the calculation of heat output of common dry-type transformer is carried out in this way. Let's introduce it in detail with the editor of dry-type transformer manufacturer
The heating capacity of dry-type transformer is basically no-load loss + load loss
Taking s9-500kva dry-type transformer as an example, no-load loss + load loss = 6.06kw, and the power consumed per hour is 6.06kwh
According to the thermal work equivalent of 1 card (thermochemical card) = 4.1840 joules
1 kwh = 3600000 joules
The calorific value basis of dry-type transformer is no-load loss + load loss
No load loss: when the secondary winding of dry-type transformer is open circuit and the rated voltage of rated frequency sinusoidal waveform is applied to the primary winding, the active power consumed is called no-load loss.
Load loss: variable loss. It is proportional to the square of the current passing through. Load loss is the load loss at rated current and reference temperature. To expand, the so-called rated current refers to the primary tap position must be the main tap, not other tap rated current.
For reference temperature, it depends on the heat resistance grade of insulation material of dry-type transformer. For oil immersed dry-type transformer, whether it is self cooling, air-cooled or forced oil air-cooled, there are A-class insulation materials. The reference temperature is specified according to the traditional concept, which is 75 ℃.
The above is the introduction of common dry-type transformer calorific value. For dry-type transformer, you should pay attention to the calculation. In this way, the dry-type transformer can enhance the efficiency and function, and play a greater advantage and efficiency.
