Longitudinal Load Limiting Devices For Transmission Lines And The Like
US Patent:
7732708, Jun 8, 2010
Filed:
Dec 16, 2005
Appl. No.:
11/303667
Inventors:
Alan B. Peabody - Anchorage AK, US
International Classification:
H02G 7/20
US Classification:
174 40R, 174 42, 174 45 R, 174 45 TD, 174 40 TD, 248 61, 248 63, 361107
Abstract:
A device for limiting loads on towers that limits loads only in the longitudinal direction and does not affect the manner in which vertical and transverse loads are resisted by the structure. The device incorporates a shield to prevent ice buildup that could affect its operation. It also has optional antifriction bearings to provide a consistent release force independent of the amount of ice that may accumulate on the wires. The device is of simple construction. The device includes an optional energy absorber, such as that used in U. S. Pat. No. 3,211,260 that can provide a resisting force that is within the longitudinal strength of the tower. The device includes both a mechanical fuse and an energy absorbing mechanism that is used to arrest the wire movement. The energy absorber can extend as much as 50 ft to safely absorb the energy released by broken wires with heavy ice coatings.
Transmission Tower Devices For Reducing Longitudinal Shock Loads
US Patent:
7057103, Jun 6, 2006
Filed:
May 6, 2005
Appl. No.:
11/123302
Inventors:
Alan B Peabody - Anchorage AK, US
International Classification:
H02G 7/20
US Classification:
174 45R, 174 40 R, 174 45 TD
Abstract:
A device for reducing a shock load having a longitudinal direction along a power line coupled through an insulator to a crossarm of a transmission tower, comprising: a rotary damper coupled between the insulator and the crossarm for rotating by the insulator in the longitudinal direction in response to the shock load, the damper having an axle to which the insulator is rotatably coupled; and, a torsion bar coupled at a first end to the axle and at a second end to the crossarm for resisting rotation of the insulator, whereby at least a portion of the shock load is absorbed.
