Abstract
A line protection system described herein provides reliable electro-mechanical connections between system components, reduces mechanical stresses on a disconnector, assures more effective disconnection of a failed arrestor, and is lower in cost than existing systems. The line protection system includes a surge arrestor, a disconnector coupled to the surge arrestor, and a line lead coupled to the disconnector. The line lead generally is a high strength cable and/or the line protection system generally does not include a shunt bypass assembly. Upon exposure to a high voltage condition, the disconnector actuates and separates the line lead from the system.
Claims20
A line protection system, comprising:
- a surge arrestor;
- a first disconnector coupled to the surge arrestor;
- a line lead having a first end and a second end, the first end of the line lead coupled to the first disconnector;
- and
- a second disconnector coupled to the second end of the line lead,
- whereby exposure to a high voltage condition causes the line lead to disconnect at the first disconnector and the second disconnector.
A line protection system, comprising:
- a surge arrestor;
- a disconnector coupled to the surge arrestor;
- and
- a line lead coupled to the disconnector, wherein the line lead comprises a high strength cable, and wherein the line protection system does not comprise a shunt bypass assembly.
A line protection system, comprising:
- a surge arrestor;
- a disconnector coupled to the surge arrestor by a first conductive connector;
- and
- a line lead coupled to the disconnector by a second conductive connector.
