Description
Technical field
The utility model relates to lightning arrester, the horizontal lightning arrester of especially a kind of ultra high voltage (1000KV).
Background technology
Along with the raising of the electric pressure of transmission system, the lightning arrester height of vertical installation is more and more higher, and in order to overcome above-mentioned defective, the horizontal lightning arrester of keeping away that level is installed arises at the historic moment.For keeping away horizontal lightning arrester, its inner medium position need be installed the intermediate insulation support column lightning arrester core body is played support and fixation, but the intermediate insulation support column has occupied the part installation site of internal equalizer, and the security performance of lightning arrester is impacted.
Summary of the invention
The purpose of this utility model is to provide a kind of ultra high voltage (1000KV) horizontal lightning arrester, can avoid the lightning arrester internal equalizer to conflict with the installation of lightning arrester intermediate insulation support column, and its internal equalizer has reasonable in design, beneficial effect simple in structure, that connection is reliable, easy for installation.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
The horizontal lightning arrester of a kind of ultra high voltage, comprise pressure-equalizing device, housing, be positioned at the stem stem of housing central authorities, be separately fixed at preceding insulation support column, intermediate insulation support column, the back insulation yoke plate of stem stem front end, middle part, rear end, it is characterized in that described pressure-equalizing device comprises grading ring, all presses the grading shield of segmental arc and cup-shaped; Described grading shield side-inversion and between preceding insulation support column and stem stem front end, its cup-shaped opening points to stem stem rear end, and described grading ring is fixed on by connecting rod on the opening of grading shield, all presses segmental arc to be fixed on the grading ring by connecting rod.
Further characteristics of the present utility model and improvement are:
The described segmental arc of all pressing is two pairs, all presses segmental arc about stem stem center symmetric arrangement for every pair, all presses between the segmental arc for two pairs and fixes by connecting rod, and described intermediate insulation support column is all pressed between the segmental arc at two pairs.
The described segmental arc of all pressing is the quadrant segmental arc, and the two ends of its arc section are provided with Metal Ball.
In the utility model, pressure-equalizing device comprises grading ring, all presses the grading shield of segmental arc and cup-shaped; Described grading shield side-inversion and between preceding insulation support column and stem stem front end, its cup-shaped opening are pointed to back insulation support column, and grading ring is fixed on by connecting rod on the opening of grading shield, all presses segmental arc to be fixed on the grading ring by connecting rod; And owing to all press segmental arc is two pairs, all press segmental arc about stem stem center symmetric arrangement for every pair, all press between the segmental arc for two pairs and fix by connecting rod, the intermediate insulation support column is all pressed between the segmental arc at two pairs, all pressing segmental arc is the quadrant segmental arc, all press for two pairs and leave the gap between the segmental arc, the intermediate insulation support column is separate with pressure-equalizing device, unaffected, simple in structure, it is reliable, easy for installation to be connected.All pressing segmental arc is the quadrant segmental arc, and the two ends of its arc section are provided with Metal Ball, and the electric field that Metal Ball can balanced all be pressed the segmental arc end improves electric field environment.
