Abstract
An isolator protection device can include a housing having at least one wall and a first coupling feature, where the at least one all forms a cavity, where the first coupling feature is configured to couple to an arrester, and where the at least one wall is configured to house an isolator body of an isolator within the cavity. The isolator protection device can also include a securing device disposed within the cavity, where the securing device is configured to secure a stud of the isolator to the isolator body during normal operating conditions.
Claims20
An isolator protection device, comprising:
- a housing comprising at least one wall and a first coupling feature, wherein the at least one wall comprises a top wall portion and at least one side wall portion, wherein the first coupling feature comprises an aperture that traverses the top wall portion, wherein the top wall portion and the at least one side wall portion form a cavity having a bottom end, wherein the first coupling feature is configured to couple to an arrester, wherein the aperture of the first coupling feature is configured to receive an arrester coupling device of the arrester, and wherein the at least one wall is configured to house an isolator body of an isolator within the cavity, wherein the isolator comprises an isolator coupling device that is coupled to the arrester coupling device;
- and
- a securing device disposed within the cavity toward the bottom end, wherein the securing device is configured to secure a stud of the isolator relative to the isolator body during normal operating conditions, and said stud physically releases when a fault current is detected.
An electrical transmission system, comprising:
- an arrester comprising:
- an isolator comprising an isolator body, an isolator coupling device, and a stud coupled to a distal end of the isolator body;
- and
- an isolator protection device coupled to the arrester, wherein the isolator protection device comprises:
- a housing comprising at least one wall and a first coupling feature, wherein the at least one wall comprises a top wall portion and at least one side wall portion, wherein the first coupling feature comprises an aperture that traverses the top wall portion, wherein the top wall portion and the at least one side wall portion form a cavity having a bottom end, wherein the first coupling feature couples to the arrester, wherein the aperture of the first coupling feature is configured to receive an arrester coupling device of the arrester, and wherein the isolator body and at least a portion of the stud is disposed within the cavity during normal operating conditions, wherein the isolator coupling device is coupled to the arrester coupling device;
- and
- a securing device disposed within the cavity toward the bottom end, wherein the securing device couples to the stud of the isolator and helps maintain a coupling between the stud and the isolator body during normal operating conditions, and said stud physically releases when a fault current is detected.
