Abstract
The present invention discloses a 220 KV transformer sleeve. The sleeve includes a sleeve assembly and a connecting assembly. The sleeve assembly includes a sleeve brace, an adjustable part coupled with the sleeve brace. The connecting assembly includes a rotating part and a mobile part. The sleeve is secured on the transformer core body through screws, and the adjustable part can be opened through the connecting assembly. When maintenance is required, there is no need to dismantle the entire sleeve. The work efficiency is greatly improved. This minimizes inductance leakage and prevents eddy currents from occurring.
