Abstract
The utility model discloses a novel lightning protection device, and belongs to the field of lightning protection of high tension lines. The novel lightning protection device comprises an insulated terminal and a lightning arrester, wherein the top end of the insulated terminal is fixed on a high-voltage cable, and the bottom end thereof is grounded; the lightning arrester is arranged with the insulated terminal side by side; a U-shaped lightning stroke electricity guiding part is arranged at the top of the lightning arrester; the high-voltage cable passes through a groove of the U-shaped lightning stroke electricity guiding part; the novel lightning protection device further comprises an adjusting structure for adjusting the distance between the high-voltage cable and the groove of the U-shaped lightning stroke electricity guiding part; and the bottom end of the insulated terminal and the bottom end of the lightning arrester are connected and grounded through the regulating structure. In case of lightning stroke, the novel lightning protection device can strike through the discharge clearance provided by the U-shaped lightning stroke electricity guiding part, so that the zinc oxide lightning arrester acts to limit the lightning overvoltage to be lower than flashover voltage of an insulator, and then the power frequency afterflow is intercepted through the zinc oxide lightning arrester, so that the accidents of trip and conducting wire breakage, which are caused by lightning stroke flashover, can be avoided, and the power supply reliability is high.
Description
Technical field
The utility model belongs to high-voltage line lightning protection field, is specifically related to a kind of Novel lightning-proof device.
Background technology
In high-tension distributing line, be easy to the lightning strikes event, especially in the distribution line of 10KV, because insulation level is lower, easier lightning strikes event, the main cause that causes the lightning-caused breaking situation is to build arc at the lightning stroke flashover passage to form power frequency continued flow, the temperature of arc root is very high, can at short notice wire be blown, even plain conductor, if the electric current that passes through is very large, also wire can be blown.
The lightning protection measures of prior art has the overhead ground wire of installation, puncture arc-preventing metal utensil, lightning protection pillar insulator and lightning arrester etc., and so also there are various problems in these measures, and lightning protection effect is not good, need to improve.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, Novel lightning-proof device that power supply reliability is high.
The technical scheme that realizes the utility model purpose is a kind of Novel lightning-proof device, comprise insulated terminal, lightning arrester, the top of described insulated terminal is fixed on the high-tension cable, bottom ground connection, described lightning arrester and insulated terminal are arranged side by side, the top of described lightning arrester is provided with the U-shaped thunderbolt and draws electric section, described high-tension cable passes the groove setting that electric section is drawn in the U-shaped thunderbolt, comprise also and regulate the adjustment structure that the groove distance of electric section is drawn in high-tension cable and U-shaped thunderbolt that the bottom of described insulated terminal and the bottom of lightning arrester are by the adjustment structure also ground connection that links to each other.
Described adjustment structure comprises fixed head and adjustable skid, described fixed head links to each other with the bottom of insulated terminal, described adjustable skid links to each other with the bottom of described lightning arrester, described fixed head is provided with the chute that adjustable skid is installed, described adjustable skid is arranged in the chute, described fixed head is provided with the strip screw, and described adjustable skid is provided with circular screwhole, and described fixed head links to each other by bolt with adjustable skid.The utlity model has positive effect: of the present utility model simple in structure, be provided with the U-shaped thunderbolt at the top of lightning arrester and draw electric section, high-tension cable passes described U-shaped thunderbolt and draws the groove of electric section, when thunderbolt is arranged, can puncture the U-shaped thunderbolt and draw the discharging gap that electric section provides, make the zinc oxide arrester action, lightning overvoltage is limited under the flashover voltage of insulator, then by zinc oxide arrester power frequency continued flow is blocked, can prevent the tripping operation and the conductor cord disconnection accident that are caused by lightning stroke flashover, power supply reliability is high.
Further also be provided with the thunderbolt of adjusting U-shaped and draw the groove of electric section and the adjustment structure of high-tension cable position, can suitably regulate the position that electric section and high-tension cable are drawn in thunderbolt, to guarantee that lightning arrester can work.
