This application discloses a
transformer bushing, comprising a conductive rod and a head
assembly, a composite insulator, an intermediate
flange, and a
tail assembly connected in sequence. The conductive rod passes through the head
assembly, composite insulator, intermediate
flange, and
tail assembly in sequence. The oil conservator of the head assembly includes an interconnected cabinet and end caps, with at least one pressure relief device on the end caps. The second end of the cabinet is fixed to the first end of the composite insulator, the second end of the composite insulator is fixed to the first end of the intermediate
flange, and the second end of the intermediate flange is fixed to the first end of the oil-insulated tube in the
tail assembly using
adhesive. The
internal pressure of the oil conservator during failure is greater than the
internal pressure of the composite insulator during failure but less than the
internal pressure of the oil-insulated tube during failure. The solution of this application can ensure the
structural integrity of the
transformer bushing during operation and prevent
transformer oil leakage due to damage to the transformer
bushing.
