Abstract
A current transformer arrangement for a gas-insulated switchgear is provided. The current transformer arrangement includes an adapter having a housing, the housing defining a first end connection opening, a second end connection opening and a hollow interior, a current conductor passing through the hollow interior of the adapter, and an annular current transformer core surrounding an exterior of the housing for measuring a current of the current conductor.
Claims8
A current transformer arrangement for a gas insulated switchgear device, comprising:
- an adapter for connection to the gas insulated switchgear device, the adapter having a first housing, the first housing defining a first inner conical end connection opening, a second inner conical end connection opening, and an interior passage extending between the first conical end connection opening and the second conical end connection opening;
- a connector disposed between the adapter and the gas insulated switchgear device, the connector having a second housing, the second housing having a first outer conical portion that is positioned within the gas-insulated switchgear device and a second outer conical portion positioned exterior to the gas insulated switchgear device positioned within the first end connection opening of the adapter, and a conductor passing through the connector from the first outer conical portion to the second outer conical portion;
- and
- at least one annular current transformer for measuring a current of the current conductor, the at least one annular current transformer comprising an annular current transformer core and a secondary winding,
- wherein the secondary winding of the at least one annular current transformer surrounding an exterior of the first housing of the adapter, the second outer conical portion of the connector within the first inner conical end connection opening of the first housing of the adapter, and the current conductor passing through second outer conical portion of the connector, and
- wherein the at least one annular current transformer is attached to the exterior of the first housing of the adapter by an insulating adhesive.
