专利汇可以提供Power transformer having flux shields surrounding metallic structural members专利检索，专利查询，专利分析的服务。并且Structural members projecting from the transformer tank are surrounded by flux shields to prevent leakage flux from entering and heating the structural members. The flux shields are constructed of a non-magnetic material which has relatively good electrical conductivity. Current induced into the flux shield by the leakage flux produces flux which counteracts the leakage flux and reduces heating of the structural members.，下面是Power transformer having flux shields surrounding metallic structural members专利的具体信息内容。

权利要求

1. A power transformer comprising: a tank assembly; a magnetic core disposed within said tank assembly; a winding assembly inductively coupled to said magnetic core; structural members projecting from the surface of said tank assembly and bracing said core; and flux shields which surround disposed adjacent to said structural members and which effectively reduce the leakage flux entering said structural members, said flux shields being constructed of a relatively good electrical conducting, non-magnetic material.

2. The power transformer of claim 1 wherein the flux shields are constructed of a metallic plate having a thickness which is greater than the skin depth of the plate at the frequency of the flux in the core.

3. The power transformer of claim 1 wherein the flux shields surround substantially the entire projecting surface of the structural members.

4. The power transformer of claim 1 wherein the flux shield is constructed of a U-shaped channel member.

5. The power transformer of claim 1 wherein the flux shield is constructed of aluminum.

6. A power transformer comprising: a tank assembly; a magnetic core disposed within said tank assembly; a winding assembly inductively coupled to said magnetic core; structural supporting members which project from the surface of said tank assembly and brace said core; and flux shields surrounding substantially the entire projecting surface of said supporTing members; said flux shields being constructed of a metallic plate having a thickness which is greater than the skin depth of the plate at the frequency of the magnetic flux in said core, and said metallic plate being constructed of a relatively good electrical conducting, non-magnetic material.
