Distribution Transformer Introduction
Stationary power distribution transformer is an electrical equipment, is used to a certain value of the AC voltage (current) becomes the same frequency as the value of one or another type of voltage (current) of the device. When the primary winding to the AC, it creates an mcb circuit breaker magnetic flux, alternating
Magnetic flux through the core effects induced in the secondary winding of the AC electromotive force. Secondary induced electromotive force and the level of a secondary winding turns much air circuit breaker ,, that the voltage is proportional to the size and number of turns. Main role is to transmit power, therefore, the rated capacity is its main parameters.
Rated capacity is a manifestation of the power of conventional value, which is characterized by transmission of electrical energy in kVA or MVA said that when the rated voltage is applied to the transformer, according to it to determine the required conditions does not Electric energy meter the temperature limits of the rated current. Now more energy-efficient power transformers non-
Crystal alloy core distribution transformers, the biggest advantage is that the ultra-low no-load loss values. Load loss can ultimately ensure that the value of the entire design process to consider the core issues. When the structural arrangement of the product, in addition to consider the amorphous alloy core itself from external forces, the same
When reasonably accurate in the calculation must also select the characteristic parameters of amorphous alloys. Domestic production of large power transformer manufacturers have TBEA Shandong Ming, Tebian Ro transformers.
