Everyone knows that there are many gears of box-type transformers, and the gears are different, and the speed of operation of box-type transformers is different. The box-type transformer needs to be adjusted continuously during the operation. There are many problems that need to be paid attention to in the process of adjusting the gear of the box-type transformer, so how does the box-type transformer adjust the gear? Let's take a look with the editor of Anhui Dali.

When adjusting the gear position, the tap power switch should be adjusted to the opposite position according to the output working voltage. The basic elements of adjusting the tap power switch are: when the output working voltage of the box-type transformer is less than the control value, the tap power switch position should be adjusted from The I gear is adjusted to the II gear, or the II gear is adjusted to the III gear. When the output working voltage of the box-type transformer is higher than the control value, adjust the position of the tap power switch from Ⅲ to Ⅱ, or from Ⅱ to Ⅰ. After adjusting the gears, use a DC bridge to accurately measure the measured values of various winding resistances, and check that the intermediate resistances of each winding are more than 2% apart. Be sure to adjust them again. Otherwise, after operation, the sound circuit breaker will not touch well. And hot, and even charging and discharging, damage the box transformer.

The effect of the iron core is to improve the magnetic coupling between the two coils. In order to reduce the eddy and eddy current loss in the iron, the iron core is extruded from a painted ferrite core; there is no electrical connection between the two coils, and the coil is wound by an insulating copper core wire (or aluminum wire cable) become. One coil connected to alternating current is called the primary coil (or primary coil), and the other coil connected to high-power electrical appliances is called the secondary coil (or secondary coil).
