Abstract
A surge arrester includes at least one resistor element and a cage in which the at least one resistor element is disposed. The cage includes an upper holder, a lower holder and at least three insulating rods, which are each held at one respective rod end thereof by the upper holder and at the other respective rod end thereof by the lower holder. The upper holder and the lower holder are configured in such a way that they each enable at least two different positions for at least one of the insulating rods, relative to the two holders, and the at least one insulating rod can be positioned differently relative to the two holders.
Claims11
A surge arrester, comprising:
- a cage including an upper holder, a lower holder and at least three insulating rods having rod ends;
- one of said rod ends of each of said insulating rods being held by said upper holder and the other of said rod ends of each of said insulating rods being held by said lower holder;
- said upper holder and said lower holder each configured to allow at least two different positions for at least one of said insulating rods relative to said holders;
- said holders each configured to allow positioning of said at least one insulating rod differently relative to said holders;
- at least one resistor element disposed in said cage;
- said upper holder and said lower holder each having a respective slot formed therein through which a respective one of said rod ends of said variably positioned insulating rod passes to fasten said at least one variably positioned insulating rod;
- and
- a tightening strap configured to be adjusted during mounting, to be passed around said variably positioned insulating rod and to exert a tensile force on said variably positioned insulating rod in direction of said at least one resistor element.
A surge arrester, comprising:
- a cage including an upper holder, a lower holder and at least three insulating rods having rod ends;
- one of said rod ends of each of said insulating rods being held by said upper holder and the other of said rod ends of each of said insulating rods being held by said lower holder;
- said upper holder and said lower holder each configured to allow at least two different positions for at least one of said insulating rods relative to said holders;
- said holders each configured to allow positioning of said at least one insulating rod differently relative to said holders;
- at least one resistor element disposed in said cage;
- at least one intermediate holder disposed between said upper holder and said lower holder;
- said at least one intermediate holder having a slot formed therein with a longitudinal direction extending radially outward from a center of said cage, said slot configured to allow said variably positioned insulating rod to pass therethrough, for fastening said at least one variably positioned insulating rod;
- and
- an adjustable tightening strap passed around said variably positioned insulating rod and configured to exert a tensile force on said variably positioned insulating rod, in direction of said center of said cage.
A surge arrester, comprising:
- a cage including an upper holder, a lower holder and at least three insulating rods having rod ends;
- one of said rod ends of each of said insulating rods being held by said upper holder and the other of said rod ends of each of said insulating rods being held by said lower holder;
- said upper holder and said lower holder each configured to allow at least two different positions for at least one of said insulating rods relative to said holders;
- said holders each configured to allow positioning of said at least one insulating rod differently relative to said holders;
- and
- at least one resistor element disposed in said cage;
- at least said upper holder and said lower holder each having an outer contour with a holding device and a ring having a mechanical damping effect applied in said holding device.
