Abstract
The invention particularly relates to a gap adjusting mechanism for a 500-kV pure air gap surge arrester, which solves the problem that the pure air gap surge arrester is relatively difficult to mount, and a gap distance is difficult to adjust. A distance between a top electrode and a bottom electrode of a discharging gap can be intermittently or continuously adjusted through the gap adjusting mechanism which comprises a coarse adjusting part and a fine adjusting part. The gap adjusting mechanism provided by the invention has the advantages of reasonable structure, convenience in installation, easiness in utilization and high reliability.
Description
Technical field
The present invention relates to lightning arrester field, be specially the pure air gap arrester clearance adjustment mechanism of a kind of 500kV.
Background technology
From domestic and international 500kV transmission line employing nineties lightning arrester, do after lightning protection device, obtained good effect.Conventionally wire (12) is to utilize line insulator (13) to hang in cross arm of tower (14) below.Lightning arrester has two kinds of versions: a kind of is insulator supporting gap type; A kind of Shi Chun air gap type.Two kinds of lightning arresters respectively have pluses and minuses.With regard to its electric property and operation stability and operation, detect property Lai Jiang，Chun air gap type lightning arrester and be far superior to composite insulator supporting gap type.Owing to there is any abnormal failure lightning arrester, can not affect system safety operation, therefore adopt in large quantities pure air gap type abroad.Even in the standard of IEC, all there is no composite insulator support type lightning arrester.But relative complex while installing due to pure air gap type lightning arrester, clearance distance adjustment is more difficult, to use, brings certain difficulty.
Summary of the invention
When the present invention installs in order to solve pure air gap type lightning arrester, relative complex, the more difficult problem of clearance distance adjustment, provide the pure air gap arrester clearance adjustment mechanism of a kind of 500kV.
The present invention adopts following technical scheme to realize: the pure air gap arrester clearance adjustment mechanism of 500kV, comprise the fixedly fixing lower plate of train wheel bridge and some lightning arresters of a lightning arrester being fixed on cross arm of tower, lightning arrester fixedly train wheel bridge left end is provided with discharge counter, lightning arrester is the protruding cantilever that is provided with of train wheel bridge left end fixedly, lightning arrester main body has been hung in cantilever below, lightning arrester body below is fixed with discharging gap top electrode, between lightning arrester main body and discharging gap top electrode, be provided with some C type adjustment blocks, on the wire of discharging gap top electrode below, be fixed with gap rod, on the rod of gap, be fixed with discharging gap bottom electrode, discharging gap bottom electrode comprises the bottom electrode supporting bracket that is supported on rod top, gap, in bottom electrode supporting bracket, utilize Height Adjustment bolt to be supported with bottom electrode discharging rod supporting bracket, in bottom electrode discharging rod supporting bracket, be fixed with bottom electrode discharging rod.
Adjusting mechanism is divided into two parts, and the some C type adjustment blocks between lightning arrester main body and discharging gap top electrode, as coarse adjustment part, are adjusted the height of discharging gap top electrode by changing the quantity of C type adjustment block; Height Adjustment bolt is as fine setting part, by turning the height of the continuous trickle adjustment bottom electrode discharging rod of Height Adjustment bolt; Thereby realize the adjustment of discharging gap.C type piece is according to calculative determination quantity, and Height Adjustment bolt is according to calculative determination height, and distance is adjusted suitable rear locking Height Adjustment bolt.
Beneficial effect of the present invention is as follows: utilize a clearance adjustment mechanism that comprises coarse adjustment part and fine setting part, realized the distance between interruption or continuous setup discharging gap top electrode and discharging gap bottom electrode.The present invention is rational in infrastructure, easy for installation, easy-to-use and reliability is high.
