The dry-type transformer regulator switch has several gears

The dry-type transformer's gear is continuously adjusted, when adjusting the dry-type transformer's gear, we need to pay attention to various dry ways of adjustment and the main methods of adjustment, dry-type transformer's gear adjustment is many, moreover dry-type transformer's gear adjustment needs to pay attention the question is also many. So common dry-type transformer gear is how to adjust it? Or with the dry-type transformer manufacturers of small series together to understand the dry-type transformer gear related adjustment:

　　When adjusting the gear, the tap-changer should be adjusted to the corresponding position according to the output voltage. The basic principle of adjusting the tap-changer is: when the output voltage of the dry-type transformer is below the allowable value, the tap-changer position should be adjusted from I to II, or second gear to third gear. When the output voltage of the dry-type transformer is higher than the allowable value, adjust the tap-changer position from III TO II, or II TO I. After adjusting the gear, use the DC Bridge to measure the DC resistance value of each winding, check the resistance value difference between each winding is more than 2% , must be adjusted again, otherwise, after operation, the dynamic and static contact will be heated due to bad contact, or even discharge, damaged dry-type transformer. The role of the core is to strengthen the magnetic coupling between the two coils. To Reduce Eddy current and hysteresis losses in iron, the core is laminated with painted silicon steel sheets; there is no electrical connection between the two coils, which are wound with insulated copper (or aluminum) wires. One coil connected to an AC power supply is called a primary coil (or primary coil) , and the other coil connected to an appliance is called a secondary coil (or secondary coil) . Above is the common dry-type transformer gear the main adjustment and the main adjustment method of the main gear for your reference, for the dry-type transformer gear you have any other need to know, please visit our website for more information.
