Abstract
The utility model discloses a lightning protection device which comprises an iron tower rod arranged outside a transformer substation, and an electricity conduction cable provided with an arc extinction switch. One end of the arc extinction switch is connected with an earth wire. A lightning protection structure is arranged between the electricity conduction cable and the iron tower rod. According to the lightning protection device, the lightning protection structure is arranged between the electricity conduction cable and the iron tower rod outside the transformer substation, and therefore the problems of large occupied area and high cost due to the fact that a lightning protection structure in a traditional technique is placed inside a transformer substation are solved, the occupied area is saved effectively, the cost is reduced, and the lightning protection effect is good.
Description
Technical field
The utility model belongs to transformer station lightning protection field, is specifically related to a kind of protection of arrester device.
Background technology
Transformer station generally has lightning-protection device; its lightning-protection device can be contained in the transformer station; also can fill on the terminal pole or head end bar outside the transformer station; existing transformer station lightning-protection device generally is mounted in the transformer station; yet lightning-protection device is installed in the transformer station, has not only increased floor space, increased capital expenditure; but also need to do the anti-property test of a large amount of gaplesss, cost is large.
Summary of the invention
The purpose of this utility model provides on a kind of terminal pole or head end bar that is arranged on outside the transformer station, can reduce the lightning-protection device of floor space, reduction cost.
The technical scheme that realizes the utility model purpose provides a kind of lightning-protection device; comprise the iron tower pole that is arranged on outside the transformer station and the conductive cable that is provided with arc-suppressing switch; one termination ground wire of described arc-suppressing switch is provided with the lightning protection structure between described conductive cable and iron tower pole.
Described lightning protection structure comprises lightning arrester and lightning-arrest disconnect; described lightning-arrest disconnect comprises cylindrical electrode and the annular electrode that matches with cylindrical electrode; one end of described lightning arrester is connected with iron tower pole; the other end of lightning arrester is electrically connected with cylindrical electrode, and an end of described annular electrode is connected electrically on the conductive cable of arc-suppressing switch away from ground wire one end.
Also comprise electric capacity, described electric capacity is arranged between arc-suppressing switch and the ground wire.
Described iron tower pole is terminal pole.
Described iron tower pole is the head end bar.
The utlity model has positive effect: the utility model is arranged on the lightning protection structure between the iron tower pole and conductive cable outside the transformer station; solved in the conventional art because the lightning protection structure is placed on the deficiency that the floor space that causes transformer station inside is wide, cost is high; effectively saved floor space; lowered cost, and lightning protection effect is good.
