Abstract
The utility model relates to a Suspension knockout lightning arrester, which is formed by the orderly connection for a suspension beam 1, an insulation substring 2, a hanging nose 3, a lightning arrester 4, a pressure releasing peeling body 5, a ground wire 6, an anti-swinging insulation substring 7, a spring 8 and an anchor 9. When the lightning arrester has a failure, the utility model makes the ground wire separated from the lightning arrester through automatic falling of the pressure releasing peeling body 5, which can ensure the safe running for the electric network after the lightning arrester has a failure.
Description
Technical field: the utility model relates to the lightning arrester that the electric equipment that moves is protected in power network.
Background technology: be used for lightning arrester that the electric equipment that moves at power network is protected at present; be sitting type structure; when lightning arrester self breaks down; because of it can not be out of service from power network automatically; often cause the ground short circuit situation of power network, so that lead to the large-area pernicious power outage of power network by lightning arrester and pedestal and the earth connection.
Summary of the invention: the purpose of this utility model provides a kind of pedestal of not having, when lightning arrester self breaks down, can make the pressure of lightning arrester bottom discharge the body that comes off automatically falls earthward together with ground wire and lightning arrester disengaging, automatically out of service from power network, the ground short circuit and the power outage that power network can not occur are guaranteed the suspension separation-type lightning arrester that power network still can safe operation after lightning arrester breaks down.It discharges come off body, ground wire, anti-sway insulator string, spring and earth anchor by hanging beam, insulator string, hanging nose, lightning arrester, pressure successively and interconnects and form, pressure discharges the body that comes off for having the round metal plate-like body of ground wire binding post on it, and it is welded on the insulator inwall of lightning arrester bottom by its dish edge.It is low that the present invention also has cost, the advantage of easy to maintenance and monitoring safety.
Description of drawings: accompanying drawing is the utility model example structure schematic diagram.
Embodiment: as shown in the figure, it discharges come off body 5, ground wire 6, anti-sway insulator string 7, spring 8 and earth anchor 9 by hanging beam 1, insulator string 2, hanging nose 3, lightning arrester 4, pressure successively and interconnects and form, pressure discharges the body 5 that comes off for having the round metal plate-like body of ground wire binding post 10 on it, and it is welded on the lightning arrester 4 bottom insulator inwalls by its dish edge.Present embodiment also is provided with safe fence 11 and lightning arrester ruuning situation monitoring case 12.
