Selection Of Switch Parameters Of Tap Changer

The switching parameter of the tap switch refers to the rated characteristic of the current, the level voltage and the level capacity.

Rated through the current when the tap is running. It must take the maximum passing current of the transformer to be transmitted as the rated value of the tap switch.

The maximum rated pass current is the maximum passing current of the tap switch, and its value is different from the design, and the current-related type test is based on the current.

The rated level voltage is the working voltage between adjacent points. The rated level voltage of the tap switch is the maximum allowable voltage when a rated pass current value. Rated rated voltage associated with the rated level voltage at current rating.

The maximum rated voltage is the maximum level voltage allowed by the tap switch, and its value varies with design. The transition resistance of the load tap changer is designed according to the actual value of the transformer's maximum voltage and rated passing current using the tap switch.
