Abstract

The present invention relates to a system for assessing a health index of a switchgear, and the system comprises a remaining life assessment unit that calculates a remaining life of the switchgear based on a number of uses, a number of operations, and history information of the switchgear; a deterioration degree assessment unit that examines a deterioration degree of the switchgear based on installation environment information and inspection information; a risk degree assessment unit that detects a risk degree of the switchgear based on partial discharge data, insulating gas analysis data, and temperature data; and a health index assessment unit that assesses a health index of the switchgear based on the remaining life information of the switchgear, the deterioration degree information, and the risk degree information of the switchgear.

Claims

1. A system for assessing a health index of a switchgear, the system comprising:

a remaining life assessment unit that calculates a remaining life of the switchgear based on a number of uses, a number of operations, and history information of the switchgear;

a deterioration degree assessment unit that examines a deterioration degree of the switchgear based on installation environment information and inspection information;

a risk degree assessment unit that determines a risk degree of the switchgear based on partial discharge data, insulating gas analysis data, and temperature data; and

a health index assessment unit that assesses a health index of the switchgear based on the remaining life information of the switchgear calculated by the remaining life assessment unit, the deterioration degree information of the switchgear examined by the deterioration degree assessment unit, and the risk degree information of the switchgear detected by the risk degree assessment unit.

2. The system of claim 1, further comprising:

a display unit that displays a remaining life, a deterioration degree of the switchgear, and a risk degree as a result of assessing the health index.

3. The system of claim 1, wherein the remaining life assessment unit comprises:

a usage information detection unit that receives a period of use information of the switchgear and a number of operations information of the switchgear to detect a usage of the switchgear;

a history information detection unit that receives the manufacturer information of the switchgear, and the use and type information of the switchgear to detect the history information of the switchgear; and

a remaining life detection unit that determines a remaining life of the switchgear based on usage information detected from the usage information detection unit and history information detected from the history information detection unit.

4. The system of claim 3, wherein the remaining life detection unit is configured to assign a weight according to the importance to a period of use of the switchgear, a number of operations, manufacturer information, the use and type information of the switchgear to determine a remaining life of the switchgear.

5. The system of claim 1, wherein the deterioration degree assessment unit comprises:

an installation environment examination unit that receives installation environment information and the importance information of an electric power line to examine the installation environment of the switchgear;

an inspection information detection unit that detects an inspection status of the switchgear based on the body status information of the switchgear, enclosure information, connection material status information, and flooding information; and

a deterioration degree examination unit that examines a deterioration degree of the switchgear based on information examined by the installation environment examination unit and inspection information detected by the inspection information detection unit.

6. The system of claim 5, wherein the deterioration degree examination unit is configured to assign a weight according to the importance to installation environment information, the importance information of an electric power line, body status information, enclosure information, connection material status information, and flooding information, respectively, to examine a deterioration degree of the switchgear.

7. The system of claim 1, wherein the risk degree assessment unit comprises:

a partial discharge analysis unit that analyzes a partial discharge occurring at the switchgear based on data received from a partial discharge detection sensor installed in the switchgear;

an insulating gas analysis unit that analyzes an insulating gas leak occurring at the switchgear based on data received from an insulating gas detection sensor installed in the switchgear;

a temperature analysis unit that analyzes a temperature of the switchgear based on data received from a temperature sensor installed in the switchgear; and

a risk degree detection unit that determines a risk degree of the switchgear based on information received from the partial discharge analysis unit, the insulating gas analysis unit, and the temperature analysis unit.

8. The system of claim 7, wherein the risk degree detection unit is configured to assign a weight according to the importance to partial discharge data, insulating gas information, and temperature information to determine a risk degree of the switchgear.
