Abstract
A kind of reversal of the natural order of things type lightning arrester, the present invention relates to lightning protection equipment field, steel tower cross-arm has been bolted fixed mount, lightning arrester body is hung upside down on steel tower cross-arm by the lightning arrester draw ring be arranged on lightning arrester body by fixed mount, lightning arrester draw ring is connected with lightning arrester body upper end electricity-leading end, lightning arrester body silicon rubber casings is provided with the dead ring that more than 5 groups sizes are alternate, the discharge end of lightning arrester body low side is provided with disconnector, and disconnector is connected with the also hook wire clamp be arranged on high-voltage conducting wires by wire; Lightning arrester body upper end electricity-leading end is also connected with detector by wire A.Beneficial effect of the present invention is: protective value is excellent, can limit circuit lightning overvoltage and various switching overvoltage; Lightning arrester body has excellent sealing property and explosion-resistance characteristic; Lightning arrester high-pressure side installs disconnector additional, avoids the generation of serious accident; Hang the arrester ground end installed and adopt side outlet method, conveniently to install and linkage counter or monitor.
Description
one, technical field
The present invention relates to lightning protection equipment field, particularly one reversal of the natural order of things type lightning arrester.
two, prior art
Alternating current gapless metal oxide arrester is for the protection of AC input transformation device, from lightning overvoltage and switching overvoltage infringement, be applicable to transformer, transmission line, switchboard, switch cubicle, electric metering box, vacuum switch, parallel capacitor, the overvoltage protection such as electric rotating machine and semiconductor device, lightning arrester is under normal system operating voltage, present high resistance state, microampere order electric current is only had to pass through, under the effect of overvoltage big current, it just presents low resistance, thus limit the residual voltage at lightning arrester two ends, existing protection of arrester working range is all (see standard at below height above sea level 1000m, GB11032-2010), also do not have a kind of lightning arrester can use safely in high altitude localities, this is just imperative in the urgent need to developing the lightning arrester that a kind of height above sea level 1000 ~ 5000m scope can use safely.
three, summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of reversal of the natural order of things type lightning arrester, it is characterized in that: steel tower cross-arm (1) is fixed with fixed mount (4) by bolt (11), lightning arrester body (5) is hung upside down on steel tower cross-arm (1) by the lightning arrester draw ring (12) be arranged on lightning arrester body (5) by fixed mount (4), lightning arrester draw ring (12) is connected with lightning arrester body (5) upper end electricity-leading end (13), lightning arrester body (5) silicon rubber casings is provided with the dead ring (10) that more than 5 groups sizes are alternate, the discharge end (14) of lightning arrester body (5) low side is provided with disconnector (6), disconnector (6) is connected with the also hook wire clamp (8) be arranged on high-voltage conducting wires (9) by wire (7), lightning arrester body (5) upper end electricity-leading end (13) is also by wire A(3) be connected with detector (2).
Beneficial effect of the present invention is: volume is little, lightweight, anti-pollution characteristic strong, and protective value is excellent, not only can limit circuit lightning overvoltage, and various switching overvoltage can be limited, not only can protection circuit insulator, also can protect power cable, also can make power station lightning arrester and use; Lightning arrester body adopts silicon rubber injection molding process to make whole product become not aeriferous solid monolithic, has excellent sealing property and explosion-resistance characteristic; Lightning arrester high-pressure side can install disconnector additional, when lightning arrester breaks down, can realize rapidly the disengaging with high-voltage conducting wires, avoid the generation of serious accident, effectively ensures that security of operation improves power supply quality; Hang the arrester ground end installed and adopt side outlet method, conveniently to install and linkage counter or monitor.
